Maintenance
The Complete Home Maintenance Checklist (Monthly, Seasonal & Annual)
Most expensive home repairs are not surprises. They are deferred maintenance that finally came due. A roof leak is usually five years of clogged gutters. A failed compressor is usually four summers of a dirty coil.
This checklist organizes home maintenance the way professionals think about it: by interval, not by room. Work through it once and you will have a defensible record of your property's condition.
Monthly tasks (15 minutes)
These are the low-effort checks that catch problems while they are still cheap.
- Replace or inspect HVAC filters
- Test smoke and carbon monoxide detectors
- Run water in unused sinks and showers to keep traps sealed
- Check under sinks and around the water heater for moisture
- Clear debris from exterior condenser units
Quarterly tasks
Every three months, look at the systems that fail slowly.
- Test GFCI outlets and breaker function
- Flush a gallon from the water heater drain valve
- Inspect caulking at tubs, showers, and exterior penetrations
- Check garage door reversing sensors
- Walk the perimeter for grading, cracks, or standing water
Seasonal tasks
Spring and fall are the two windows where climate does the most damage. Gutters, roofing, and HVAC changeovers belong here.
- Spring: clean gutters, service the air conditioner, inspect roof after winter
- Summer: check irrigation, seal decks, service pool equipment
- Fall: service the furnace, clear gutters again, winterize exterior spigots
- Winter: monitor ice dams, check attic insulation and ventilation
Annual tasks
Once a year, bring in a professional for the systems where DIY inspection is not enough: chimney sweeping, HVAC tune-up, septic inspection, and a full roof review.
Photograph everything. A dated photo library is the difference between an approved insurance claim and a denied one.
Turn the checklist into a record
A checklist you complete but never document has no resale or insurance value. Store service receipts, warranty documents, and photos in one place — that record is what Doma-Guard calls a Property Passport, and it is what turns maintenance into provable value.
Frequently asked questions
How often should I do home maintenance?
Plan on a 15-minute monthly walkthrough, a deeper quarterly check, a seasonal push in spring and fall, and one professional review each year.
What is the most commonly skipped maintenance task?
Gutter cleaning and HVAC filter changes. Both are inexpensive and both cause disproportionately expensive damage when neglected.
