The most expensive home repairs are almost always preventable. A clogged gutter becomes a $4,000 foundation repair. An ignored HVAC filter becomes a $6,000 system replacement. The good news: most prevention is completely free — it just requires your attention a few times a year.
Here is your complete, seasonal checklist of maintenance tasks that cost nothing but time.
Spring Checklist
1. Inspect Your Roof from the Ground
After winter, walk around your home with binoculars and look for missing, curling, or cracked shingles. Catching a problem early means a $300 repair instead of a $12,000 roof replacement. You don't need to climb up — just look.
2. Clean Your Gutters
Clogged gutters force water against your fascia boards and foundation. Clear them every spring and fall. All you need is a ladder, gloves, and a bucket. Takes about an hour for most homes.
3. Test Every Smoke and CO Detector
Press the test button on every detector. Replace batteries in any that are slow to respond. The NFPA recommends replacing the entire unit every 10 years.
4. Check Exterior Caulking
Walk around all windows and doors and look for cracked or missing caulk. A $6 tube of exterior caulk can prevent water intrusion that leads to rot, mold, and thousands in damage.
5. Flush Your Water Heater
Sediment builds up at the bottom of your water heater tank and reduces efficiency — and lifespan. Attach a hose to the drain valve, run it outside, and flush until the water runs clear. Takes 20 minutes and can add years to the unit's life.
Summer Checklist
6. Check Your HVAC Filter
A dirty filter makes your system work harder, shortens its life, and raises your energy bill. Check it monthly during heavy use seasons. A $10 filter swap is far cheaper than a $7,000 AC replacement.
7. Inspect Your Deck or Patio
Look for loose boards, wobbly railings, and signs of rot. Poke any suspicious wood with a screwdriver — if it sinks in easily, you have rot. Catching it early means replacing one board, not the entire deck.
8. Clear Dryer Vents
Clogged dryer vents are a leading cause of house fires. Disconnect the vent hose from the back of the dryer and clean out any lint buildup. Do this at least once a year.
Fall Checklist
9. Service Your Heating System
Call an HVAC tech for a seasonal tune-up before you need the heat — it's cheaper and they're more available. A well-maintained furnace lasts 20+ years; a neglected one lasts 10.
10. Seal Gaps Around Pipes and Wires
Walk your basement and look for gaps where pipes or cables enter the home. A can of spray foam (under $10) seals out cold air, pests, and moisture.
11. Trim Trees Near the House
Branches overhanging your roof are a liability — in a storm, they become projectiles. Keep all branches at least 6 feet from your roofline. Many municipalities offer free tree trimming on public trees.
12. Check Your Sump Pump
Pour a bucket of water into the sump pit to confirm the pump activates and drains quickly. A failed sump pump during a heavy rain can mean a flooded basement — a $10,000+ disaster.
Winter Checklist
13. Know Where Your Water Shutoff Is
A burst pipe can dump 100 gallons of water into your home per hour. Every adult in the house should know exactly where the main shutoff valve is and how to turn it off.
14. Insulate Exposed Pipes
Pipes in unheated spaces — garages, crawl spaces, exterior walls — are vulnerable to freezing. Foam pipe insulation costs pennies per foot at any hardware store.
15. Check Door and Window Weatherstripping
Hold a candle near the edges of exterior doors and windows on a cold day. Flickering flame means air is leaking in. Replacing weatherstripping is a simple DIY fix that lowers your heating bill immediately.
