Homeownership is one of life’s biggest investments. And while it offers comfort and security, it also comes with responsibilities that many homeowners don’t expect until something goes wrong. The truth is, most of those costly home repairs aren’t the result of one big event – but a series of small, preventable issues that went unnoticed or unaddressed.
The good news? A little maintenance goes a long way. With regular check-ins and small fixes, you can prevent bigger (and more expensive) problems later on.
Below, we’ve compiled 10 common home maintenance tasks that are simple to manage when caught early, but often become costly if ignored. We’ve ordered them from the most frequent and easiest to handle, to the less frequent or more complex – so you can start with the simple wins and work your way down the list.
1. Clean Dryer Lint to Prevent Fire Hazards
Why it matters: Dryer lint is one of the most common causes of household fires. Even if you clean the lint trap regularly, lint can still build up in the dryer vent or exhaust duct over time.
What to do:
Clean the lint trap after every load.
Deep-clean the dryer vent and hose at least once a year, or more often if you’re noticing longer drying times.
Use a long-handled dryer vent brush to remove hard-to-reach lint and debris.
Pro tip: If you can’t recall the last time your dryer vent was cleaned, schedule it now. The job takes less than an hour and can prevent costly damage.
2. Replace HVAC Filters
Why it matters: Clogged or dirty air filters reduce the efficiency of your heating and cooling system and force it to work harder. This raises your energy bill and shortens the life of the system. Dirty filters can also impact your indoor air quality.
What to do:
Thoroughly clean or replace your HVAC filter every 1–3 months depending on the type of filter and whether you have pets, allergies, or a dusty environment.
Set a calendar reminder or sign up for a filter subscription to stay on track.
Pro tip: Write the date of installation on the filter frame so you always know how long it’s been in use.
3. Fix Leaky Faucets and Running Toilets
Why it matters: A slow-dripping faucet or constantly-running toilet can waste hundreds of gallons of water per year, driving up your water bill and putting unnecessary strain on your plumbing.
What to do:
Check faucets for drips and tighten loose fittings.
If a toilet runs nonstop, replace the flapper or float valve – usually a quick and inexpensive DIY fix.
Pro tip: Put a few drops of food coloring in your toilet tank. If it seeps into the bowl without flushing, you just caught a silent leak.
4. Reseal Caulking Around Windows, Doors, and Fixtures
Why it matters: Cracked or missing caulk around tubs, sinks, windows, and doors can let in moisture, drafts, and even pests. Left unchecked, this can lead to water damage, mold, and increased energy costs.
What to do:
Inspect caulking annually for cracks or gaps.
Remove old caulk and reapply a fresh bead where needed, using a waterproof and mold-resistant product in wet areas.
Pro tip: Use painter’s tape along the edges before applying caulk for a clean, professional-looking line.
5. Clean Gutters and Downspouts
Why it matters: When gutters clog with leaves and debris, rainwater can overflow and pool near your foundation, leading to leaks, mold, and even structural issues.
What to do:
Clean your gutters at least twice a year (typically in the spring and fall).
Check that downspouts direct water at least five feet away from your foundation.
Pro tip: If your home is surrounded by trees, consider installing gutter guards to cut down on future cleanings.
6. Monitor Drainage Around Your Home
Why it matters: Improper grading or pooling water near your home can cause damage to your foundation, encourage basement leaks, and contribute to mold growth.
What to do:
After heavy rain, walk around your home to check for standing water.
Extend downspouts and ensure the soil slopes away from your home.
For recurring issues, consider installing a French drain or regrading the soil.
Pro tip: Landscaping solutions like dry creek beds or gravel trenches can also improve drainage and curb appeal.
7. Trim Tree Branches Near Your Roof
Why it matters: Overhanging branches can damage your roof, clog gutters, and give pests like squirrels or raccoons a direct route into your attic.
What to do:
Trim branches so they are at least 6-10 feet away from your roof.
Check for overgrowth at least once a year, especially before storm season.
Pro tip: Always hire a certified arborist for larger limbs or trees near power lines.
8. Flush Your Water Heater
Why it matters: Over time, sediment builds up at the bottom of your water heater, reducing its efficiency and lifespan. This buildup can also clog your system and affect water pressure.
What to do:
Turn off the heater and let the water cool.
Attach a hose to the drain valve and flush the tank until water runs clear.
Perform this task annually for best results.
Pro tip: Be sure to consult your manufacturer’s instructions! Some newer models are self-cleaning or have different flushing requirements.
9. Inspect for Foundation Cracks
Why it matters: Small cracks in your home’s foundation can widen over time, potentially compromising structural integrity or letting in water.
What to do:
Walk your home’s exterior and interior walls seasonally to check for new or expanding cracks.
Fill small cracks with concrete filler or sealant.
If you notice shifting, sagging, or wide cracks, consult a professional.
Pro tip: Mark cracks with a pencil and date them. This helps you track whether they’re growing.
10. Inspect Your Roof for Damage
Why it matters: Minor roof issues like missing shingles or cracked flashing (protective metal trim) can quickly lead to leaks, insulation damage, or mold problems if left unattended.
What to do:
Check your roof seasonally and after major storms.
Look for missing, curled, or broken shingles, and check flashing around chimneys and vents.
Schedule a professional inspection every few years.
Pro tip: Use binoculars from the ground or rent a drone if it’s unsafe to climb on your roof.
Small Fixes = Big Savings
Staying on top of basic home maintenance doesn’t require a huge budget or expert-level skills. Just a little DIY, a diligent eye, and a consistent approach. By addressing small issues early, you can avoid costly repairs, preserve your home’s value, and enjoy greater peace of mind.
Whether you start with replacing air filters or checking your gutters, every small step adds up. Consider creating a seasonal maintenance calendar to stay on top of everything. And don’t forget – the best time to fix a problem is before it becomes one.
