Spring Home Maintenance Checklist

Quick overview

Spring maintenance focuses on two goals: undoing what winter did and preparing the house for summer heat. Winter's freeze-thaw cycles crack caulking, clog gutters with debris, stress roofing, and leave outdoor plumbing shut down. Summer's early demand goes to the air conditioner and outdoor water systems. Catching problems in April or May is almost always cheaper than discovering them during a heatwave.

Recommended frequency

Complete this checklist once per year, in spring. The best window is after the last hard frost in your region — typically March through May depending on your climate. Pair it with the fall home maintenance checklist for a complete two-season schedule.

Tools and materials

• Ladder (for gutter inspection at eave height only — do not walk the roof yourself)
• Garden hose with spray nozzle
• Pressure washer (optional)
• Screwdriver and replacement batteries (9V or AA, check detector specs)
• Window screen repair kit or replacement screens
• Exterior caulk and caulk gun
• HVAC air filter (correct size — check your furnace/air handler label)
• Flashlight

Safety considerations

Most spring maintenance tasks are genuinely low-risk. The main hazards to keep in mind:

• Ladder safety. Use a stable, properly rated ladder on level ground. Have someone hold it when possible. Never lean past the ladder's side rails.
• Electrical. Do not open the outdoor AC condenser or touch wiring inside. Cleaning coil fins and clearing debris around the unit is safe; anything involving electrical components is not.
• Roof work. Visual inspection from a ladder at the eave, or with binoculars from the ground, is the safe approach for most homeowners. Walking a roof — especially after rain — is a significant fall risk.
• Pressure washer. Keep the spray moving to avoid surface damage and never aim at windows, vents, or light fixtures.

Maintenance checklist

Exterior and roof

• Visually inspect the roof from the ground or from a ladder at eave height — look for missing, curled, or lifted shingles
• Check flashing around chimneys, skylights, and vents
• Clear gutters and downspouts of winter debris; flush with a hose
• Confirm downspouts direct water at least 6 feet away from the foundation
• Inspect exterior caulking around windows, doors, and penetrations; re-caulk where cracked or missing
• Check wood trim, fascia, and siding for paint peeling or rot
• Power wash concrete walkways, driveway, and deck if needed

Outdoor plumbing and irrigation

• Reconnect and turn on outdoor hose bibs; check for leaks at the supply valve and at the bib itself
• Inspect hoses and nozzles for winter cracks
• Start up the irrigation system and check each zone for broken or misaligned heads
• Check the backflow preventer if your irrigation system has one (visual inspection only)

HVAC and cooling

• Replace the HVAC air filter (check your system's manual for the correct interval; many call for every 1–3 months)
• Clear at least 2 feet of clearance around the outdoor AC condenser — remove leaves, debris, and any mulch that has crept close
• Test the AC system on a mild day before you need it
• Clean or replace the dehumidifier filter if you use one

Deck and outdoor living

• Inspect deck boards for rot, raised screws, and loose fasteners; tighten or replace as needed
• Check deck ledger board connection to the house
• Apply deck stain or sealant if the surface is due (water beading test: sprinkle water — if it soaks in rather than beading, it is time to reseal)

Windows, doors, and screens

• Install or re-install window and door screens; repair or replace any with holes or bent frames
• Check weatherstripping on doors and windows; replace sections that no longer compress fully
• Clean window tracks and lubricate slides with dry silicone spray

Safety devices

• Test every smoke detector — press the test button and confirm the alarm sounds
• Test every carbon monoxide detector
• Replace batteries in battery-only detectors (even if not yet triggered)
• Check manufacturing dates on detectors: replace smoke detectors older than 10 years, CO detectors older than 5–7 years
• Inspect and recharge or replace fire extinguishers if older than 6 years or showing a low-pressure gauge reading

Step-by-step safe tasks

Flushing and inspecting gutters

1. Wait for dry weather so gutters are not full of water.
2. Set the ladder at the downspout end first. Remove any leaf debris by hand or with a small trowel.
3. Work along the gutter toward the high end, removing debris into a bucket.
4. Run a hose at the high end to flush remaining debris toward the downspout. Confirm water flows freely out the downspout bottom.
5. Check that the gutter has a slight pitch toward the downspout (roughly 1/4 inch per 10 feet). A level section will hold standing water.

Testing the air conditioner

1. Set the thermostat fan to "Auto" and mode to "Cool."
2. Lower the set point 3–5°F below room temperature.
3. Listen for the outdoor unit to start within a minute or two.
4. Feel the supply registers — air should feel noticeably cool within 5 minutes.
5. If the unit runs but air is warm, or the outdoor unit does not start, schedule service before summer.

Reconnecting outdoor faucets

1. Locate the indoor shutoff valve that feeds each outdoor hose bib. These are often in the basement or crawl space.
2. Open the valve slowly.
3. Go outside and check the hose bib for drips at the packing nut and at the threaded connection. A slow drip around the handle usually means the packing washer needs replacing — a straightforward repair.
4. Run water and check for adequate flow. A slow flow can indicate a partially closed valve or a frozen section that cracked the pipe over winter.

Tasks best left to a professional

• HVAC refrigerant check and recharge. Refrigerant is regulated; only EPA 608-certified technicians may purchase and handle it. If your AC runs but does not cool, a refrigerant issue is possible — call an HVAC company.
• Roof shingle repair or replacement. Walking a roof safely requires training and fall protection equipment. If you spot missing or damaged shingles, contact a licensed roofing contractor.
• Electrical panel inspection. If you want to verify your home's electrical service is in good shape for summer loads, hire a licensed electrician — not a general handyman.
• Irrigation backflow preventer testing. Many municipalities require annual certified testing by a licensed plumber or irrigation professional.

Common mistakes

• Skipping the AC test. Discovering the AC does not work on the first 90°F day means a longer wait for service and possible emergency pricing. Test in May.
• Flushing gutters without checking pitch. Debris-free gutters that hold standing water still cause fascia rot and ice dams next winter. If water sits in a gutter after flushing, the slope needs adjustment.
• Ignoring caulking. Failed caulking around windows and penetrations is one of the top causes of moisture intrusion. It is a 10-minute fix with a $5 tube; the water damage it prevents can cost thousands.
• Replacing batteries without testing. Swap the battery and then press the test button. A dead detector with a fresh battery still means you are unprotected.
