The Seasonal Home Maintenance Checklist That Prevents Expensive Repairs

Almost every expensive home repair starts as a cheap one that nobody noticed. A $15 tube of caulk ignored becomes a rotted window frame; a clogged gutter becomes a foundation problem. The good news: staying ahead of it takes about an hour per season. Here's the checklist.

Spring

• Walk the roofline. From the ground with binoculars is fine — look for lifted or missing shingles after winter storms. Catching one now costs a shingle; catching it in autumn costs a ceiling.
• Clean gutters and downspouts. Water should discharge at least a few feet from the foundation. Pooling at the base of the house is the root cause of a shocking share of basement and foundation repairs.
• Service the air conditioner before the first heat wave. Rinse or replace filters and clear debris around the outdoor unit. HVAC companies charge premium rates in July; in April they're happy to see you.
• Check exterior caulk and paint. Anywhere wood meets weather, gaps let water in. Recaulking is a 20-minute job.

Summer

• Inspect washing machine hoses. A burst supply hose is one of the most common causes of home water damage. If yours are rubber and older than five years, replace them with braided stainless ones — about $20.
• Test the sump pump (if you have one) by pouring a bucket of water into the pit. It should kick on and drain. You want to learn it's dead in July, not during a November storm.
• Trim vegetation away from the house. Branches touching siding or the roof are a highway for moisture and pests.

Fall

• Gutters again — after the leaves drop. This is the one people skip, and it's the one that matters most going into winter.
• Have the furnace or boiler serviced and replace filters. A tuned system runs cheaper all winter and is far less likely to die on the coldest night of the year.
• Disconnect garden hoses and shut off exterior faucets. A frozen hose bib can split a pipe inside the wall — a four-figure repair for a two-minute task.
• Test smoke and carbon monoxide detectors and replace batteries. Heating season is CO season.

Winter

• Watch for ice dams — thick ridges of ice at the roof edge mean heat is escaping into the attic. Better attic insulation fixes the cause; a roof rake manages the symptom.
• Keep an eye on humidity. Persistent condensation on windows breeds mold and rots frames. Running bathroom fans longer or cracking a window briefly usually solves it.
• Flush the water heater (or have it done) to clear sediment. It extends the tank's life and lowers the energy bill.

The bottom line

Four hours a year, mostly with tools you already own. Insurance industry data consistently shows water damage and heating failures among the most common — and most preventable — home insurance claims. This checklist is aimed squarely at both.
