The Home Maintenance Schedule That Prevents Expensive Repairs

The cheapest home repair is the one you never have to make. Most four-figure emergencies — a collapsed ceiling, a flooded basement, a dead furnace in January — start as a small, ignorable problem months earlier. A simple seasonal routine catches those problems while they're still cheap. Here's the schedule.

Spring: recover from winter

• Inspect the roof for shingles loosened or lost over winter; check flashing and the attic for leak stains.
• Clean gutters and downspouts, and confirm water drains away from the foundation.
• Service the AC before the first heat wave — replace the filter, clear the condenser, test the condensate drain.
• Walk the foundation and exterior for new cracks, and reseal gaps in siding and around windows.

Summer: protect and prevent

• Reseal decks and check railings and fasteners for rot or movement.
• Test smoke and carbon-monoxide detectors and replace batteries.
• Inspect for pests — termite mud tubes, ant trails, rodent entry points — and seal gaps.
• Check exterior paint and caulk; touch up before sun and moisture get underneath.

Fall: prepare for the cold

• Service the furnace or heat pump before the first freeze — this is when a cracked heat exchanger or failing igniter shows up.
• Clean gutters again after the leaves drop.
• Drain and shut off exterior faucets and irrigation to prevent burst pipes.
• Seal drafts around doors and windows and check attic insulation levels.
• Have the chimney inspected and swept if you use a fireplace.

Winter: monitor and respond

• Watch for ice dams on the roof and condensation or moisture in the attic.
• Keep cabinet doors open on cold nights so warm air reaches pipes on exterior walls.
• Check the basement and crawl space for leaks after heavy snow or rain.
• Test the sump pump before the spring thaw.

The few-times-a-year jobs

Why this saves real money

A $20 filter protects a $6,000 HVAC system. A morning of gutter cleaning prevents thousands in foundation and basement water damage. Catching a single lifted shingle prevents a rotted roof deck. Maintenance isn't glamorous, but it's the highest-return work you'll do on your home. When something does need professional attention, estimate the cost first with the matching project calculator so you know what's fair before you call.
