The Complete Houston Home Maintenance Checklist (2026)

Schedule your HVAC inspection in March or early April — before every tech in Houston is booked solid through August. A tune-up catches refrigerant leaks, worn capacitors, and dirty coils before they fail on a 102°F day. Houston AC units run 2,000+ hours/year — twice the national average.

Houston's oak pollen season (Feb–April) clogs gutters fast. Clogged gutters push water toward your foundation — and on Houston's clay soil, that water causes the ground to swell and shift. Clean gutters after the pollen drops, before the spring rains hit hard.

Houston sits on Beaumont clay — one of the most expansive soil types in the country. It swells when wet, shrinks when dry, and moves your foundation with it. Spring is the ideal time for a structural engineer to check for new cracks, sticking doors, or uneven floors. Catching a crack early is a $500 fix. Catching it late is $10,000–$25,000.

Houston's warm, humid climate is paradise for Formosan subterranean termites — one of the most aggressive species in the U.S. Swarm season starts in April. An annual inspection by a licensed pest control company catches infestations before they hit structural wood.

Houston's humidity finds every gap. Inspect caulking around windows, doors, and where siding meets trim. Replace any cracked or peeling sealant to keep moisture and pests out before summer.

Run each zone and check for broken heads, leaks, and misaligned spray patterns. Proper irrigation keeps the soil moisture consistent around your foundation — which in Houston's clay soil, directly prevents foundation movement.

June 1 is the official start of hurricane season. By then, you should have: storm shutters or plywood pre-cut and labeled, a generator tested and fueled, trees trimmed away from the house, and a go-bag ready. Don't wait until a storm enters the Gulf — every contractor in Houston will be booked within hours of a named storm. See our complete Houston hurricane prep guide for the full week-by-week checklist.

In Houston's summer, your AC runs nearly 24/7. A dirty filter forces the compressor to work harder, drives up energy bills, and shortens the system's life. Change it every 30 days from June through September — no exceptions. Mark your calendar or let WellKept remind you.

After any major storm (hail, high winds, heavy rain), get a roofer to check for missing shingles, lifted flashing, and soft spots. Houston's summer storms are brutal on roofs, and a small leak caught in July prevents a ceiling collapse in October. File insurance claims within 30 days of the damage.

Houston summers hit 100°F+ regularly. Check your sprinkler system for leaks, coverage gaps, and broken heads. Adjust run times for summer watering restrictions (typically odd/even schedules). Consistent soil moisture prevents foundation problems during the dry summer months.

Houston attics can hit 150°F in summer. Poor ventilation traps heat, degrades shingles from below, and makes your AC fight harder. Ensure soffit vents are clear, ridge vents are unobstructed, and attic fans (if installed) are running.

Houston doesn't get brutal winters, but your heater still needs an annual check. Gas furnaces need burner and heat exchanger inspections. Heat pumps need a mode-switch test. Schedule in October before the first cold snap, when HVAC techs are less slammed than they were all summer.

Check all exterior doors and windows for drafts. Houston's mild winters still drive up heating costs if warm air leaks out. Replace worn weatherstripping on doors, and re-caulk any gaps around window frames. This also keeps Houston's bugs from finding a way in.

Houston's live oaks, pines, and pecan trees drop heavy branches in winter ice storms. Trim branches that overhang your roof, power lines, or fence. Fall is the best time — before winter storms and after the summer growth season. Never let branches touch your roof.

Houston's UV exposure and humidity wreck exterior paint faster than most U.S. markets. Inspect siding, trim, and fascia for peeling, bubbling, or bare wood. Touch up before winter rains to prevent moisture from penetrating exposed wood.

Fall leaves (yes, Houston does have a fall leaf drop — just later than up north) plus summer storm debris clog gutters again. Clean them before winter rains to keep water flowing away from your foundation.

Harris County appraisals come out in April, with a May 15 protest deadline. But fall is when you should start gathering comparable sales data and preparing your case for next year. The average successful protest saves Houston homeowners $1,200/year. WellKept tracks the deadline and prepares your filing.

Houston doesn't freeze often, but when it does, the damage is catastrophic. Winter Storm Uri (2021) caused billions in burst-pipe damage across Houston. Insulate exposed pipes in attics, garages, and exterior walls with foam sleeves. Know where your main water shut-off valve is. This is cheap insurance against a rare but devastating event.

Houston's hard water builds sediment in your water heater tank. Annual flushing extends the unit's life by 3–5 years and keeps energy bills lower. Tank-style heaters should be flushed every 12 months; tankless units need descaling every 1–2 years.

Replace batteries in every smoke and carbon monoxide detector. Test each unit. Houston's city code requires working detectors on every level and in every bedroom. Winter is heater season — CO risks go up when gas appliances run more frequently.

Lint buildup in dryer vents is a leading cause of house fires. Houston's humidity makes lint stick and compact faster. A professional cleaning once a year removes the buildup and checks the vent path for kinks or disconnections. Takes 30 minutes, prevents a disaster.

Lubricate springs, rollers, and hinges. Test the auto-reverse safety feature. Houston's humidity corrodes garage door hardware faster than dry climates. Inspect weather seals along the bottom for gaps — they keep out water, pests, and cold air.

Houston winters can be surprisingly dry. When the clay soil around your foundation dries out, it shrinks — pulling away from the slab and causing cracks. Run a soaker hose around your foundation's perimeter 2–3 times per week during dry spells. Consistent moisture is the cheapest foundation maintenance you can do.
