Spring Home Maintenance Checklist: 15 Things to Inspect Before Summer Hits

Winter is rough on a house. Freezing temps, ice, wind, and moisture spend months quietly working against your home's exterior, plumbing, and systems — and most of the damage doesn't show up until spring rolls around. The good news? A few hours of inspection in March or April can save you thousands in repairs later in the year.

Here's a practical, room-by-room checklist you can walk through yourself on a Saturday morning. No special skills required for most of it — just a sharp eye and a flashlight.

Outside First: Start Where Winter Hit Hardest

1. Walk Your Roof Line (From the Ground)

You don't need to climb up there. Grab a pair of binoculars or use your phone's zoom camera and look for:

  • Missing or curling shingles — a few missing shingles are a quick patch job; widespread curling means the roof is aging out
  • Flashing gaps around chimneys, vents, and skylights — this is where most roof leaks actually start
  • Sagging sections — that's a structural flag, call a pro right away

2. Check Your Gutters and Downspouts

After a winter of ice and debris, gutters take a beating. Run a hose through them and watch where water exits. Signs of trouble:

  • Water spilling over the sides (clogged or sagging)
  • Downspouts not directing water at least 4–6 feet from the foundation
  • Gutter sections pulling away from the fascia board

This is one of those jobs most people ignore until water starts getting into the basement. Don't be that person.

3. Inspect the Foundation

Walk the perimeter and look at ground level. You're looking for:

  • New cracks — hairline cracks in poured concrete are usually fine; horizontal cracks or stair-step cracks in block foundations are serious
  • Grading issues — the ground should slope away from your house, not toward it. If water pools near the foundation after rain, that needs to be addressed before summer storms arrive

4. Look at Your Deck or Fence

Freeze-thaw cycles love to loosen fasteners and split wood. Check:

  • Deck boards for soft spots, rot, or raised nails/screws
  • Posts for wobble at the base (rot often starts underground)
  • Fence panels for leaning sections or broken pickets

A few loose boards or a wobbly post section is a quick repair now. Let it go another season and you're replacing whole sections.

5. Caulk Around Windows and Doors

Look for cracked, shrinking, or missing caulk on the exterior. Gaps here let water in and drive up your energy bills all summer. A $6 tube of exterior caulk and 20 minutes can fix this yourself.

Inside the House: Systems and Surfaces

6. Test Every GFCI Outlet

These are the outlets with the little TEST/RESET buttons — found in bathrooms, kitchens, garages, and outdoors. Press TEST, confirm the power cuts out, then press RESET. If any outlet doesn't respond correctly, it needs to be replaced. In 2026, an electrician trip for a single GFCI swap runs about $85–$130 depending on your area.

7. Check Under Every Sink

It takes 30 seconds and catches a lot. Open the cabinet doors under kitchen and bathroom sinks and look for:

  • Water stains or mineral rings on the cabinet floor
  • Soft or swollen wood (sign of a slow, ongoing leak)
  • Rust on the drain connections or supply lines

Small drips can quietly rot out a cabinet floor over a winter. Catch it early and it's a $15 part swap. Ignore it and you're replacing the cabinet.

8. Flush Your Water Heater

Sediment builds up at the bottom of tank water heaters over time, making them work harder and shortening their lifespan. Once a year, you should attach a garden hose to the drain valve and flush a few gallons out until it runs clear. If you haven't done this in years — or ever — and the water heater is over 8 years old, have a plumber take a look at the anode rod while you're at it.

9. Test Smoke and CO Detectors

Spring is a great reminder to test every detector in the house. Hold the test button until it beeps. Replace any that don't respond. Smoke detectors should be replaced every 10 years regardless — check the manufacture date on the back.

10. Look at Your Attic (Even Briefly)

You don't have to explore it thoroughly, but poke your head in and look for:

  • Daylight coming through where it shouldn't
  • Water stains on the sheathing or insulation
  • Signs of animal activity (nesting material, droppings)

A lot of roof leaks live in the attic for months before homeowners notice them on the ceiling below.

HVAC: Get Ahead of the Heat

11. Replace the HVAC Filter

If you haven't swapped the filter since fall, do it now. A clogged filter makes your system work harder and circulates dust through the house all summer. A basic 1-inch filter runs $8–$15; a higher-quality MERV 11 filter costs $20–$35 and lasts longer.

12. Schedule an AC Tune-Up

HVAC technicians book up fast in May and June. Call now, in March or April, and you'll get a better appointment slot — and probably a lower price. A standard AC tune-up in 2026 runs $100–$175. They'll check refrigerant levels, clean coils, and make sure the system is ready before you actually need it.

13. Clear Around Outdoor AC Units

Over winter, leaves, twigs, and debris collect around and inside the condenser unit outside. Shut the power off at the disconnect box nearby, then remove any debris around the unit. Keep at least 2 feet of clearance on all sides.

Quick Checks That Take Under 5 Minutes Each

14. Run Every Faucet and Look for Drips

Do a lap around the house and briefly turn on every faucet, including outdoor hose bibs. Look for drips at the spout or base. Outdoor hose bibs sometimes crack over winter from a freeze — easy to spot, easy to fix before you need the hose.

15. Check Window and Door Hardware

Locks, hinges, and weatherstripping see a lot of expansion and contraction over winter. Tighten any loose screws on hinges, check that door locks engage cleanly, and replace weatherstripping that's flattened out or cracked.

When to Call a Pro

Most of this checklist is purely observational — you're identifying issues, not necessarily fixing them. Some things you spot will be obvious DIY jobs (replacing a filter, caulking a window). Others are worth a call:

  • Foundation cracks that are new, horizontal, or growing
  • Roof damage beyond a shingle or two
  • Any sign of water intrusion in the attic or walls
  • Electrical outlets that don't reset properly
  • Deck posts with significant rot at the base

The point of doing this walkthrough every spring isn't to alarm yourself — it's to catch the small stuff while it's still small. A $50 repair in April beats a $2,000 repair in August every single time.

If you find something on this list that needs attention and you'd rather not tackle it yourself, we're happy to take a look. Free estimates, no pressure.
