Spring Home Maintenance Checklist for East Contra Costa County

By Richard · Published February 19, 2026

Spring in the East Bay is a small window. By April we’ve had enough dry weather to see what winter damaged, and by May summer prep takes over. The two or three weeks between are the best time of year to do home maintenance — temperatures are perfect for outdoor work, the rain is mostly gone, and you’ve got a clear view of what needs attention before things get baked in by 100°F afternoons.

Here’s a practical checklist for East Contra Costa County homes.

Outside

Walk the Fence Line

Wind and wet ground in winter loosens posts and weakens panels. Do the wiggle test on every post. Look at gate hardware — gate posts are usually the first to go because they take stress every time the gate swings. More on patching vs. replacing here.

Inspect the Deck

Walk every board and look for:

• Soft spots (knock with a screwdriver handle)
• Popped or rusted fasteners
• Cracked or splintered boards
• Loose railings or wobbly handrails

If finish has stopped beading water, it’s time to refinish.

Check Caulking on the Exterior

Walk the exterior and look at every caulked seam — windows, doors, where siding meets trim. Cracks and gaps are how water gets behind siding and starts dry rot. Caulking is cheap, fast, and one of the highest-ROI maintenance projects.

Look for Dry Rot

Probe with a screwdriver at the bottom corners of windows, on fascia and eaves, around exterior door jambs, and on the bottom of porch posts. Soft = trouble. Catch it early. More on spotting dry rot here.

Clean Gutters and Test Downspouts

Run a hose into each gutter and watch where water comes out. It should leave the property at least 4–6 feet from the foundation. If water is dumping near the house or onto wood structures, that’s a project.

Pressure Wash What Needs It

Siding, walkways, driveways, and decks. Be careful with pressure on wood decks (low setting, fan tip) and on older painted siding (paint comes off fast).

Inside

HVAC Service Before Summer

Replace filters. Service the AC if you haven’t in a year or more. Clear weeds and leaves from around the outdoor condenser. Hot summer is the worst time to discover an AC problem.

Caulking in Wet Areas

Same idea as exterior caulking, but in bathrooms, kitchens, and around tubs. Re-caulk anywhere you see cracks or gaps.

Smoke and CO Detectors

Test every detector. Replace batteries that are over a year old. Replace any unit older than 10 years entirely.

Check Under-Sink Plumbing

Look for slow drips, water stains, or warped wood under kitchen and bathroom sinks. Catching a slow leak early prevents the dry rot and mold problems that come from a slow leak ignored.

Refresh Weatherstripping

If you do anything before summer, do this. Check exterior doors. Replace any weatherstripping that’s compressed, cracked, or peeling. AC bills drop measurably with fresh weatherstripping.

What’s Worth Hiring Out

If your time is limited, the items I’d bundle into a half-day handyman visit:

• Fence repair and post replacement
• Deck refinishing (or hire it as a separate project)
• Dry rot patching
• Whole-house weatherstripping refresh
• Caulking refresh on the exterior
• Door adjustments before summer makes them worse

A half-day on these items can knock out most of the high-ROI spring work for the year.
