10 Uncommon Home Maintenance Tasks Landlords Often Forget

Published on Feb 11, 2025

Landlords

Maintaining a rental property is a balancing act–one that requires attentiveness, foresight, and a knack for anticipating potential pitfalls before they blossom into expensive headaches. Amid other duties as a landlord such as rent collection, tenant communications, and everyday upkeep, it’s easy to overlook certain maintenance tasks that carry significant weight behind the scenes. From neglected dryer vents that pose a fire hazard to drafty windows causing higher energy costs, these “small” issues can decrease property value and overall tenant satisfaction.

Regular HVAC Filter Changes

Maintaining a comfortable, energy-efficient home isn’t just about installing a state of the art HVAC system It’s about giving that system the consistent care it needs. And at the top of that list? Filters. Replacing filters is something that’s easily forgotten since they’re out of sight and out of mind, but are vital to your property’s health.

Why Landlords Overlook HVAC Filters

Hidden away from daily view
HVAC filters are frequently tucked away in corners, inside panels, or behind grilles, making them an afterthought for most homeowners. Oftentimes, issues aren’t noticed until airflow starts dwindling or strange noises emerge.

Assumpting tenants may handle filter replacements
In some rental agreements, tenants are responsible for minor maintenance like replacing lightbulbs or cleaning lint traps. It’s not unreasonable for landlords to assume tenants also know how (and when) to replace HVAC filters. Assumptions often lead to oversights, especially when tenants are unaware of the recommended schedules or simply forget. A quick check in or a reminder can prevent this “who’s responsible?” confusion between both parties.

Consequences of Neglecting HVAC Filters

Reduced efficiency and higher energy costs
Picture your HVAC system as a champion long-distance runner, striving to keep interiors cozy in winter and refreshingly cool in summer. A dirty filter is like making that runner breathe through a straw. Suddenly, everything becomes a struggle, efficiency plummets, and energy bills soar. This not only affects your bottom line but also reduces overall tenant satisfaction and nobody wants a home that takes forever to heat up or cool down.

Increased wear and tear leading to expensive repairs
When the system has to work overtime just to push air through clogged filters, components like the blower motor, condenser, and other vital parts get stretched to their limits. Over time, this stress can lead to premature breakdowns or the need for major repairs that will cost more than routine maintenance ever would. A $10 filter can save you from a $1,000 repair bill.

Best Practices for HVAC Maintenance

Recommended frequency of filter replacement (every 1-3 months)
The golden rule: change or clean your filters every 1-3 months, depending on your filter type and the property’s usage. Homes with pets, smokers, or tenants who frequently host gatherings may need more frequent filter checks due to increased dander, dust, and foot traffic. If your property remains vacant or sees minimal occupancy, extending to the three month mark might be feasible to 6 months.

Reminders or digital alerts to stay on schedule
Staying on top of filter changes doesn’t have to be complicated or time consuming. Set up recurring digital alerts on your phone or property management software. You may also consider placing a small sticker on the HVAC unit to log each filter replacement date.

If you manage multiple units, a spreadsheet or app that sends automated notifications can be a landlord’s best friend. By keeping a replacement schedule, you’ll keep your HVAC system running smoothly, prolong its lifespan, and ensure your tenants remain comfortable.

Cleaning Dryer Vents

Dryer vents often go unnoticed during routine maintenance. While a clogged vent may continue to function for a time, accumulated lint restricts airflow and increases the likelihood of costly repairs or even a serious fire hazard.

Common Oversights with Dryer Vents

Only cleaning the lint trap but forgetting the vents
Many homeowners (and landlords) think they’re on top of dryer maintenance when they empty that little lint screen after every load. While that’s a vital first step, it only tackles a fraction of the debris. Lint, dust, and even errant socks can sneak past the screen and settle deep within the ducts leading to the exterior. Over time, these hidden blockages build up, restricting airflow and increasing the risk of serious problems.

Risks and Costs of Ignoring Dryer Vents

Fire hazards and increased insurance liabilities
A clogged vent isn’t just about inconvenience, it’s a potential tinderbox. Dry, compacted lint is startlingly flammable and can ignite under the high heat produced by your dryer. Even worse, if a fire breaks out and the cause is traced back to negligence, insurance providers may deny covering related damages, leaving you with a significant financial burden.

Poor drying performance leading to higher electricity bills
Have you ever stood impatiently by the dryer, wondering why the clothes still feel damp after an extra cycle? A blocked vent often forces the machine to run longer and harder, translating to higher utility bills and added wear on your appliance. Just because it’s functioning doesn’t mean it’s efficient.

How to Properly Clean Dryer Vents

Detailed steps or professional services
For the DIY crowd, cleaning a dryer vent usually involves carefully disconnecting the dryer, accessing the duct with a long brush or vacuum attachment, and removing all trapped lint. The key is being thorough by pushing and pulling the brush multiple times to dislodge any debris vents.

Don’t forget the exterior opening where critters or debris might block airflow. If you’re unsure or dealing with a particularly complicated vent setup, calling in a professional can spare you headaches (and bruised knuckles). Their specialized tools and expertise ensure a deeper clean without damaging the ductwork.

Annual vs. semi-annual cleaning schedules
Most experts advocate for a yearly inspection and cleaning, though you may need to be more attentive if your property houses larger households or sees unusually heavy laundry traffic. Keep an eye on drying times–if you notice loads taking longer than usual, it’s time for a checkup. Whether you opt for annual or semi-annual cleaning, the small investment in maintenance can save you heaps in energy costs and prevent a potentially catastrophic fire hazard.

Testing Smoke and Carbon Monoxide Detectors

Imagine suddenly being interrupted by a high-pitched “chirp” echoing through the hallway. That sound usually signals a dying battery. A warning that could save a life. Yet if these alarms are silent, it’s easy to assume everything is fine. Without proper attention, smoke and carbon monoxide detectors can fail just when they’re needed most.

Why Detector Maintenance is Often Neglected

“Out of sight, out of mind” if no chirping or battery alerts
Many landlords and tenants forget about detectors, at least until that piercing chirp or telltale red blinking light demands attention. It’s human nature: if it’s not beeping, we assume it’s working perfectly. Over time, dust, corrosion, or expired components can weaken sensors, making these lifesavers less effective, even if they look (and sound) just fine.

Liability for landlords if devices fail during an emergency
A non-functional smoke or carbon monoxide detector is more than an inconvenience, it’s a liability nightmare waiting to happen. Should an unfortunate incident occur, an improperly maintained detector can leave landlords in the crosshairs of legal repercussions.

Local regulations requiring functional detectors
From state to state, and sometimes even city by city, regulations can vary. Most municipalities agree on one thing: functional smoke and carbon monoxide detectors are non-negotiable. Many areas conduct regular property inspections that can result in fines for non-compliance. Missing or malfunctioning alarms often end up on the “must fix yesterday” list when inspectors come knocking.

Best Practices for Detector Upkeep

Monthly testing and annual battery replacement
Testing these devices is a fairly simple task. Press and hold the “test” button until you hear that chirp sound. Replacing batteries once a year (or when you hear that chirp) keeps your devices powered up. If you’re forgetful, set a recurring calendar alert or tie it to a routine event, like the start of daylight savings time.

Complete device replacement every 7–10 years
Smoke and CO detectors don’t last forever. They have built-in sensors that degrade over time–think of them as having an expiration date. Most manufacturers recommend a complete replacement at the 7–10 year mark. If you aren’t sure when a device was installed, now’s the perfect time to note its “birthday.” With fresh, modern detectors in place, you’ll rest easier knowing your property is guarded by the latest technology and reliable components.

Water Heater Maintenance

Water heaters are like the reliable sidekicks of your property’s plumbing system quietly standing by to provide that toasty shower or soothing bath at the turn of a faucet. Despite their crucial role, they’re often overlooked until the day they begin to rattle, leak, or quit working. Being proactive and giving your water heater attention can spare you (and your tenants) the shock of chilly water on a winter morning and the repair or maintenance costs that follow.

Common Reasons Water Heaters Get Ignored

Tucked away in closets or basements
Water heaters tend to be installed in nondescript corners, whether it’s a dark basement, garage, or closet. Because they operate silently (most of the time), it’s easy to forget they exist until one evening or morning when only cold water comes out from the shower head.

“If it isn’t broken, don’t fix it” mindset
Many landlords assume water heaters operate on the principle: “set it and forget it.” Just because the heater churns out hot water today doesn’t guarantee smooth sailing tomorrow. By the time odd noises or leaks surface, minor maintenance issues have often escalated into major and costly repairs.

Problems Caused by Neglected Water Heaters

Sediment buildup reducing efficiency
When minerals and debris accumulate at the bottom of the tank, your once efficient water heater starts to work doubletime. When your water heater is struggling to keep water hot it can translate to poor performance and higher energy bills.

Higher utility bills and premature failures
Combine the extra workload with prolonged neglect, and you may be looking at a recipe for disaster—both in terms of monthly utility costs and overall equipment lifespan. A heater strained by sediment and poor upkeep is more likely to experience breakdowns, leaks, or complete failure long before its time. In the worst cases, a catastrophic rupture can flood basements, ruin flooring, and leave you facing a hefty repair tab.

Routine Water Heater Care

Annual flushing to remove debris
Flushing your water heater once a year is a straightforward yet highly effective way to keep it in top condition. By draining the tank and removing mineral-laden sediment, you’ll instantly boost efficiency and reduce the risk of rust. It’s like hitting the “reset” button on a device that otherwise accumulates internal gunk over time.

Checking temperature and pressure relief valves
Water heaters aren’t just big metal tanks; they’re pressurized systems. The temperature and pressure relief (TPR) valve acts as the safety net, releasing pressure if it builds to dangerous levels.

A quick test involves lifting the valve’s handle and ensuring water flows freely, then letting it snap shut. If it’s rusty or refuses to open, it’s time for a valve replacement. This small inspection step can prevent big, messy problems.. think spewing water or even an exploding tank. A few minutes of TPR valve testing each year can save you thousands in cleanup and replacement costs, not to mention preserving your peace of mind.

Gutter and Downspout Inspections

Let’s face it: gutters and downspouts are rarely on top of anyone’s maintenance list. They quietly usher rainwater away from your roof, but gutters need regular check ups to keep performing at their best. Neglecting them can transform a small oversight into an expensive repair.

Why Gutters Are Often Overlooked

Out of reach areas that don’t get checked until a major clog
Gutters are typically perched far above eye level, making them easy to forget. It’s not uncommon for property owners to notice an issue only after a heavy downpour sends water cascading over the sides of the exterior. By then, leaves, twigs, and other debris have accumulated, forcing water to find alternate routes, often through your roof or siding.

Potential Damage from Clogged Gutters

Roof damage, fascia rot, and foundation issues
When gutters fail to drain properly, water pools and seeps into the edges of the roof, leading to leaks and costly shingle or underlayment repairs. The excess moisture can also wreak havoc on the fascia boards, those wooden panels at the roofline, causing them to rot. Water that continues down to the foundation can erode soil, potentially cracking the foundation and undermining the structural integrity of the entire property.

Water leaks and mold growth
Standing water is a haven for mold and mildew. Once these fungi latch on, they’re stubborn and can spread like wildfire, especially in humid climates. What begins as a dark patch can balloon into a full scale mold infestation inside walls. This could lead to health concerns and require professional mitigation.

Gutter Maintenance Schedule

Clearing debris twice a year (spring and fall)
Gutters typically need a good cleaning at least twice a year. Once after the leaves have fallen in the autumn and again in spring to clear out winter debris. In areas with particularly heavy foliage or frequent storms, you may need to give your gutters a little extra TLC. Grab a sturdy ladder, some gloves, and a bucket, or hire a professional for a risk free clean out.

Ensuring downspouts direct water away from the property
Even if your gutters are clean, problems can persist if downspouts aren’t carrying water a safe distance from your foundation. Extenders or splash blocks can help channel runoff further away, preventing pooling or erosion around your home’s perimeter. A quick inspection after a steady rainfall will tell you if water is pooling where it shouldn’t. if so, you’ll know it’s time for a downspout adjustment or upgrade.

Sealing and Caulking Windows and Doors

Windows and doors do more than let in light and provide an exit point. Gaps or deteriorated seals can compromise energy efficiency and open the door to water damage. By regularly inspecting and maintaining these barriers, landlords protect both their investment and their tenants’ comfort.

Indications of Failing Seals

Drafts or visible cracks around frames
A telltale sign of compromised seals is a persistent draft wafting through the property, often near windowsills or door jambs. You might notice small gaps where caulk has dried, cracked, or pulled away from the frame. A quick “hand test” on a breezy day can be done by placing your palm near the window or edges of the door to confirm if air is seeping inside.

Increased heating or cooling bills
If your energy bill has a sudden increase, your windows or doors could be the culprits. When cold or hot air infiltrates, HVAC systems work overtime to maintain a comfortable interior temperature. This added workload translates to higher utility bills.

Consequences of Ignoring Caulking

Water seepage leading to mold or wood rot
Water has no boundaries. It seeps through the tiny openings, leading to discolored drywall, warped wood, and an ideal breeding ground for mold and mildew. Over time, even small leaks can turn into significant structural problems, forcing you to undertake pricey repairs that could have been avoided with a simple routine maintenance. 

Higher energy costs due to poor insulation
Ignoring deteriorating caulk is like leaving a window perpetually cracked open. In winter, your heating system strains to fill the gap; in summer, the AC is constantly battling rising indoor temperatures. The result is a spike in energy consumption, resulting in a higher monthly bill. Not to mention, tenants are quick to notice when the property feels drafty or uncomfortable.

Best Times to Reseal

Annually inspect before extreme weather seasons
A proactive approach is to schedule an annual inspection. Ideally, annual inspections should happen during mild weather such as before the summer heat or before winter cold sets in. This timing allows you to address minor problems before they escalate under harsher conditions. It’s akin to checking a car’s tires before embarking on a long road trip: it might be a small inconvenience now, but it saves you from major headaches down the line.

Use weatherproof caulk for long lasting results
Not all caulks are created equal. Investing in high quality, weatherproof formulas ensures a durable seal that can withstand temperature fluctuations, UV rays, and moisture. A good product can spare you from frequent reapplication. The goal is maximum efficiency with minimal fuss.

Quarterly Plumbing Checks

Periodic plumbing checks can uncover hidden leaks, such as under the sink, before they spiral into a costly repair. By scheduling routine inspections, landlords safeguard their property’s integrity and keep tenants happy.

Commonly Missed Areas

Under sink cabinets and around toilets
When was the last time you opened the cabinet beneath the sink? These spaces often gather clutter and dust, making a slow leak nearly impossible to spot. The same goes for that narrow gap behind the toilet where a leak can go undetected until it’s soaked through the floor or stained the ceiling below.

Hidden leaks in seldom used bathrooms
A guest bathroom or basement half bath might remain unused for weeks at a time. Because no one’s frequently running the taps or flushing the toilet, minor leaks can go unnoticed, gradually causing damage behind walls or under floors.

Impact of Unchecked Leaks

Mold and mildew growth
Water plus darkness equals a breeding ground for mold and mildew. Over time, spores can spread into drywall, insulation, and even HVAC ducts, creating health concerns for tenants and resulting in a full blown remediation.

Escalating water bills and structural damage
A hidden leak can quietly waste large volumes of water, leading to higher utility bills and potential penalties if the property exceeds local usage regulations. Continuous moisture also weakens wooden supports, corrodes metal fixtures, and gradually compromises the building’s foundation.

Simple Steps to Prevent Plumbing Disasters

Routine visual checks for moisture
A flashlight and a few extra minutes can be game changers. Open cabinets, peer around toilet bases, and don’t forget to inspect walls or ceilings directly beneath plumbing fixtures. Look for staining, bubbling paint, or even a musty smell. These subtle clues often indicate there may be a leak somewhere.

Prompt repairs or professional plumbing inspections
The moment you spot or suspect a leak you need to act fast. Many landlords have a “wait and see” mentality, hoping the issue will magically resolve itself. Spoiler alert: it won’t. Call in a qualified plumber or arrange for a thorough inspection if something seems off. A prompt response can transform a potential disaster into a manageable repair job, ultimately saving you time, money, and more than a few headaches.

Checking Sump Pumps (If Applicable)

Sump pumps might sit idle for months or even years, but when heavy rain or snowmelt threatens to turn your basement into a small lake, these pumps spring into action, but only if they’re in good working order. Overlooking sump pump checks is easy, but failing to do so can set the stage for watery chaos.

Why Sump Pumps Go Unnoticed

Located in basements or crawl spaces
Basements and crawl spaces aren’t typically high-traffic areas, meaning out of sight often becomes out of mind. Because sump pumps are rarely front and center, property owners may forget to inspect them. Months or years can roll by before a sudden storm reveals a problem hidden beneath that dusty trapdoor.

Not triggered unless there is heavy rainfall or flooding
Sump pumps sit idle  in “standby mode,” waiting for water levels to rise enough to trigger them. If you’ve been lucky with relatively dry seasons, you might never hear that reassuring hum. Unfortunately, it’s easy to assume all is well until the skies open up and you’re ankle deep in water, scrambling to figure out why your sump pump is silent.

Risks of a Non-Functional Sump Pump

Basement flooding and property damage
A malfunctioning sump pump can swiftly transform a cozy, finished basement into a swamp like disaster. Waterlogged drywall, ruined electronics, and soggy furniture can be painfully expensive and time consuming to address.

Costly water cleanup and mold remediation
Standing water doesn’t just evaporate overnight. It seeps into cracks, stains floors, and fosters a warm, damp environment where mold and mildew thrive. Professional water cleanup and mold remediation are no small tasks, and could result in high repair costs. Regular sump pump checks are a simple way to prevent these larger scale nightmares.

Simple Sump Pump Tests

Pour water into the pit to ensure activation
One straightforward method to test your pump’s mettle is to pour water directly into the sump pit. Keep an eye on the water level and listen for the pump to activate. A healthy sump pump should spring to life, drain the water, and shut off automatically. If it remains mute or sounds off, you’ll want to address the issue immediately.

Yearly inspections to detect mechanical failures
Even if your sump pump passes the water test, a yearly checkup by a plumbing professional can catch any subtle mechanical hiccups before they spiral into basement-flooding calamities. Think of it as scheduling a yearly doctor’s visit for your property—an ounce of prevention can mean the difference between a dry, comfortable basement and one brimming with headaches.

Exterior Paint and Wood Rot Assessment

A home’s exterior looks sharp but also shields what’s underneath from the harsh elements. Over time, paint can peel, wood can rot, and what was once pristine can deteriorate fast. Staying on top of exterior maintenance isn’t just about aesthetics; it’s about preserving the structural backbone of your property.

How Exterior Wear Occurs Gradually

Chipping paint goes unnoticed until it’s severe
Paint typically degrades slowly over time with subtle cracks or flakes appearing in inconspicuous corners. By the time the damage spreads to more visible spots, a simple touch up may no longer suffice. Paint functions as a protective coat, but once compromised, moisture, sunlight, and temperature fluctuations can assault the underlying wood.

Wood rot develops slowly and hides beneath surfaces
Unlike paint chips, which are usually visible to the naked eye, wood rot can remain undercover for months and possibly years. It might lurk behind a pristine coat of paint, gradually weakening the wood until a gentle push reveals a spongy, crumbling mess. This stealthy progression makes routine checks absolutely crucial, as waiting for a soft plank to give way underfoot is not exactly an ideal discovery method.

Consequences of Delayed Action

Structural integrity issues and increased repair costs
Once the wood begins to rot, you’re on a collision course with more expensive problems. Rafters, beams, and siding can lose their load bearing capacity, leading to sagging door frames, warped windows, or even more structural failings. These aren’t trivial or purely cosmetic, neglect can inflate a modest repair bill into a staggering one.

Pests like termites finding easy access
Termites, carpenter ants, and other hungry critters see rotting wood like an all you can eat buffet. Wherever moisture and decay meet, pests move in, chomping through the compromised wood faster than you’d expect. Before you know it, you could be hosting an uninvited insect colony, making eradication a second and equally pressing concern.

Regular Inspection Tips

Annual check for peeling paint or soft wood
A thorough walk around at least once a year can be your property’s lifesaver. Examine corners, edges, and any spots exposed to persistent moisture (like areas near gutters). Keep an eye out for paint that’s bubbling or peeling, and give suspect wooden sections a gentle push or prod. If it feels spongy, it’s time to investigate further.

Touch up paint and replace rotted wood immediately
Once you spot damage, swift action is paramount. For smaller paint chips, a quick touch-up can restore your home’s protective seal. If you discover rotting wood, remove the compromised section immediately and replace it with treated or rot resistant material. A fresh coat of high quality exterior paint can then provide a lasting shield against the elements helping you keep termites and mold at bay.

Routine Pest Prevention

Few things spook tenants or landlords quite like the sudden scuttle of roaches after a flicked on light or the sound of rodents in the walls. Pests often multiply unseen until the damage is done. Being proactive with pest control is the most effective strategy to keep these unwelcome guests from appearing.

Why Proactive Pest Control Is Often Ignored

Landlords wait until an infestation is obvious
By the time you witness a cockroach in the hallway or mouse droppings in the kitchen, you’re likely dealing with a full blown colony. Out of sight doesn’t mean out of existence. Waiting for that clear evidence can elevate a small, manageable issue into a time consuming, expensive ordeal.

Limited visibility in walls, attic, or crawl spaces
Areas such as attics and crawl spaces are rarely visited and pest populations can grow if these areas are unchecked. Rodents can chew through insulation, and insects can carve out entire nests before anyone notices, usually by the time it’s too late. The clandestine nature of these spaces makes regular inspections both essential and often overlooked.

Potential Costs of Infestations

Tenant complaints and possible health hazards
When tenants come face to face with critters, expect the phone to ring nonstop. Their alarm is justified–rodents, cockroaches, and other pests aren’t just nuisances; they can transmit diseases and trigger allergies. A single complaint on social media or a negative review can tarnish your rental’s reputation faster than you can say, “exterminator.”

Escalating extermination fees
Nipping an infestation in the bud is infinitely cheaper than treating an advanced colony. Once pests have nested, reproducing at a rapid clip, the cost of professional extermination increases by a lot. Factor in potential property damage such as chewed wiring, compromised insulation, and contaminated surfaces and repair costs can spiral out of control.

Effective Pest Prevention Measures

Seal cracks and gaps around doors and windows
Your property’s perimeter is its first line of defense. Even the tiniest gap can welcome ants, spiders, and other insects. Inspect door frames, window sills, and foundation edges for cracks and gaps. Caulking or weather stripping small cracks can make a huge difference.

Scheduled inspections and traps in high-risk areas
Routine sweeps of basements, attics, crawl spaces, and utility rooms let you spot early signs of activity such as droppings, gnaw marks, or the faint rustle of insects or rodents. Setting down traps or bait in these high risk zones can stop a future infestation. Consider hiring a local and trusted pest control service for periodic check ups, ensuring your property remains as pest free as possible.

Owning and managing a rental property isn’t just about collecting rent. By addressing the often overlooked repair and maintenance, you’ll protect your property from unnecessary wear, maintain energy efficiency, and create an environment that’s positive for tenants. Whether it’s changing HVAC filters, cleaning dryer vents, or regularly checking for leaks, these simple actions serve as both preventive measures and sound investments. Ultimately, the peace of mind gained from proactive maintenance ensures your rental remains safe, appealing, and profitable.
