Most homeowners stay on top of the obvious chores—mowing the lawn, painting touch-ups, and weekly cleaning. But what about the hidden home maintenance tasks that protect your biggest investment behind the scenes?
Neglecting these lesser-known projects can cost you big. A recent survey revealed that 60% of homeowners delay necessary maintenance and 40% have already paid for a major repair that could have been avoided with better upkeep.¹ On the flip side, research shows that well-maintained homes sell for an average of 10% more than those that aren’t.²
Here are 10 essential but often overlooked maintenance tasks that can save you thousands of dollars—and extend the life and value of your home.
1. Gutter Cleaning: Protecting Your Foundation
Clogged gutters can push rainwater into your foundation, attic, or siding, leading to rot, mold, or flooding.
- Cost of cleaning: $162 on average (up to $390 for multi-story homes)³
- Cost of neglect: $5,100 for foundation repairs or $4,300 for a flooded basement⁴⁵
Action tip: Clean gutters twice yearly (spring and fall), and consider installing gutter guards.
2. HVAC Filter Replacement: Lower Bills, Longer System Life
Dirty filters restrict airflow, strain your HVAC, and raise energy costs—sometimes even causing complete system failures.⁶
- Cost of neglect: $4,000–$12,000 for full replacement
- Savings potential: Up to 20% on energy bills, per the U.S. Department of Energy⁸
Action tip: Replace filters every 1–3 months, choose MERV 8–13, and schedule yearly tune-ups ($175–$550).⁷⁸
3. Water Heater Flushing: Avoid Tank Failure
Sediment buildup reduces efficiency and can void your warranty.
- DIY or pro cost: $160 for professional service¹⁰
- Cost of neglect: Early replacement and higher energy bills⁹
Action tip: Flush annually, replace the anode rod every 3–5 years, and follow manufacturer guidelines.
4. Dryer Vent Cleaning: Prevent Fires
Lint-clogged vents are one of the leading causes of home fires in the U.S.¹¹
- Cost of cleaning: $144 on average¹²
- Cost of neglect: Tens of thousands in fire damage
Action tip: Clean vents twice a year, replace plastic ducts with rigid metal, and watch for slow drying times.
5. Refrigerator Coil Cleaning: Cut Energy Waste
Dusty coils can spike refrigerator energy use by 35%.¹³
Action tip: Every six months, vacuum or brush coils and clear fan areas. This no-cost DIY task lowers bills and extends appliance life.
6. Garage Door Lubrication: $10 vs. $1,000 Repair
Friction damages springs and openers, leading to expensive breakdowns.¹⁴
- Cost of lubricant: ~$10
- Cost of new opener: $350–$1,000 installed¹⁴
Action tip: Annually lubricate moving parts with the recommended product, and inspect for wear.¹⁵
7. Sump Pump Testing: Flood Insurance for Your Basement
Your sump pump protects your basement, but only if it works during a storm.
- Cost of neglect: Thousands in flood cleanup⁵
Action tip: Test quarterly by pouring water into the pit, and clean the inlet screen yearly.
8. Chimney Cleaning: Reduce Fire Risk
Dirty chimneys cause 30% of home heating fires.¹⁶
- Cost of cleaning: $100–$350¹⁷
- Cost of neglect: Fire and structural damage
Action tip: Hire a certified sweep annually, burn only seasoned wood, and add a chimney cap.
9. Roof Inspection: Catch Small Issues Early
Your roof faces constant stress, and repair costs are climbing fast (28% year-over-year).¹⁹
- Average inspection: $239 (sometimes free)¹⁸
- Average replacement: $9,500²⁰
Action tip: Inspect twice yearly, check attics for leaks, and book professional inspections every 1–2 years.
10. Water Pressure Monitoring: Protect Your Plumbing
Excess water pressure (above 80 psi) can quietly destroy pipes, appliances, and fixtures.²¹
Action tip: Test annually with a pressure gauge. Maintain 40–60 psi and install a regulator if needed.
Build a Proactive Maintenance Schedule
Instead of waiting for emergencies, plan ahead:
- Budget 1–4% of your home’s purchase price annually for upkeep.²²
- Remember: well-maintained homes sell for 10% more.²
As Thumbtack economist Lucas Puente explains: “Across the U.S., buyers should be prepared to spend at least a few thousand a year in home maintenance costs.”²³
