Spring
Spring checklist
Winter is hard on a house. Spring is about finding the damage while it is still small and getting water moving away from the building again.Clean gutters and downspouts
Clogged gutters overflow against the fascia and foundation — the root cause of a shocking share of basement leaks. Scoop them out, then run a hose to confirm downspouts drain at least three feet from the house.Inspect the roof from the ground
Binoculars beat a ladder. Look for lifted or missing shingles, damaged flashing around chimneys and vents, and shingle grit collecting in gutters — all signs winter took a toll worth a professional look.Service the air conditioner before the first heat wave
Replace the filter, clear leaves and cottonwood fluff from the outdoor condenser coils, and give it a test run on the first warm day. HVAC companies book out weeks once summer actually arrives.Test the sump pump
Pour a bucket of water into the pit and confirm the pump kicks on, drains it, and shuts off. Spring storms are exactly when you find out the hard way that it seized over the winter.Check exterior caulk and paint
Walk the exterior and look at window and door trim, siding joints, and anywhere two materials meet. Cracked caulk lets water into the wall assembly; an hour with a caulk gun now prevents rot repairs later.Restart irrigation and outdoor faucets
Open the outdoor water supply slowly and watch each zone and spigot for leaks or heads broken over winter. A cracked line can run silently for months and show up only on the water bill.Summer
Summer checklist
Long days and dry weather make summer the season for exterior upkeep — the jobs that need open windows, warm temperatures, or a weekend outside.Wash siding and clean the deck
Mildew and grime eat finishes over time. Wash siding with a garden-hose foamer or pressure washer on low, and if water no longer beads on the deck, it is time to clean and reseal it.Clean the dryer vent duct
Not just the lint trap — the duct from the dryer to the outside wall. Lint buildup is a leading cause of house fires, and a clogged duct also doubles drying times. A drill-powered brush kit makes it a 30-minute job.Tune up the garage door
Lubricate rollers, hinges, and springs with garage-door lube (not WD-40), then test the safety reversal by placing a board under the door. Tighten any hardware that has rattled loose.Flush the water heater
Sediment settles on the tank bottom, making the heater noisy and inefficient and shortening its life. Hook a hose to the drain valve and flush until the water runs clear — annually is plenty.Do a pest patrol
Walk the foundation and eaves looking for carpenter-ant sawdust, wasp nests, and gaps where utilities enter the house. Seal openings with steel wool and caulk before fall, when rodents start looking for a warm place.Check window screens and weep holes
Patch or replace torn screens while windows are open daily, and clear the small weep holes at the bottom of window frames so rain drains out instead of pooling in the track.Fall
Fall checklist
Fall is deadline season: everything on this list gets dramatically more expensive or more miserable to fix after the first hard freeze.Service the furnace and replace filters
Have the furnace inspected and tuned before the first cold snap — the failure you want to find in October, not at 2 a.m. in January. Stock a season of filters while you are at it.Winterize outdoor faucets and irrigation
Disconnect hoses, shut interior supply valves to outdoor spigots, and drain or blow out irrigation lines. A burst hose bib inside the wall is one of the most expensive freeze failures a house has.Clean gutters after the leaves drop
The second gutter cleaning of the year matters most: full gutters in winter cause ice dams, which pry shingles up and push meltwater into ceilings.Seal drafts around doors and windows
On a windy day, feel around doors, windows, and outlets on exterior walls. Fresh weatherstripping and a door sweep pay for themselves in one season and make the house noticeably more comfortable.Sweep the chimney if you burn wood
Creosote buildup causes chimney fires. If you use the fireplace more than a handful of times a year, have it inspected and swept before the burning season starts.Replace smoke and CO detector batteries
Do it when the clocks change so it is automatic. Detectors themselves expire too — check the manufacture date on the back; smoke detectors are done at 10 years, CO detectors at 5–7.Winter
