Spring Home Maintenance Checklist for Denton Homeowners

Spring in Denton means warming temps, unpredictable storms, and the transition from heating to cooling. It’s the best time to catch small problems before they become expensive summer emergencies.

This checklist covers everything a Denton homeowner should address between March and May of 2026.

Exterior Checklist

Start outside. Winter weather — even a mild North Texas winter — takes a toll on your home’s exterior.

Roof and Gutters

• Walk the perimeter and look for missing or curled shingles
• Check flashing around vents, chimneys, and skylights
• Clean gutters and downspouts — Denton’s spring storms dump heavy rain fast
• Make sure downspouts direct water at least 3 feet away from your foundation

Foundation

• Inspect the perimeter for new cracks wider than 1/4 inch
• Check that the grade slopes away from the foundation on all sides
• Start your soaker hose program if you see separation between soil and foundation — Denton’s clay soil shrinks as it dries, and foundation movement is the most expensive repair you’ll face

Siding and Paint

• Look for peeling, cracking, or bubbling paint
• Check caulking around windows, doors, and trim
• Power wash siding, sidewalks, and the driveway

HVAC and Mechanical

Your AC is about to work hard for 5 straight months. A spring tune-up is non-negotiable.

• Schedule an AC tune-up — refrigerant levels, coil cleaning, electrical connections, and drain line flush
• Replace the air filter — if you haven’t changed it since fall, it’s overdue
• Test the thermostat — switch from heat to cool and verify it kicks on within a few minutes
• Clear the area around your outdoor condenser — trim vegetation back 2 feet on all sides
• Check the condensate drain line — pour a cup of white vinegar down it to prevent algae clogs (the #1 AC service call in Denton summers)

Plumbing

• Inspect outdoor faucets for freeze damage — turn each one on and check for leaks at the handle and the wall connection
• Check under every sink for slow drips or moisture
• Flush your water heater — drain 2–3 gallons from the valve to remove sediment. Denton’s hard water makes this especially important.
• Test sump pump (if you have one) before spring rains arrive

Interior Checklist

Safety Devices

• Test smoke detectors and CO detectors — replace batteries even if they still chirp
• Check fire extinguisher expiration dates
• Test GFCI outlets in bathrooms, kitchen, and garage (press the test/reset buttons)

Windows and Doors

• Check weatherstripping — worn seals let cool air escape and drive up summer energy bills
• Clean window tracks and lubricate sliding door tracks
• Inspect screens for holes or tears before mosquito season

Attic

• Look for signs of pests or moisture
• Check that attic insulation hasn’t shifted or compressed — Denton homes need R-38 minimum
• Make sure soffit vents are clear and not blocked by insulation

Yard and Irrigation

• Test your sprinkler system — run each zone and check for broken heads, misdirected spray, or low-pressure zones
• Adjust sprinkler heads so they’re not hitting the house, fence, or sidewalk
• Apply pre-emergent herbicide in early March before soil temps hit 55°F
• Mulch flower beds — 2–3 inches of hardwood mulch retains moisture and suppresses weeds

Bottom Line

Spring maintenance in Denton isn’t glamorous, but it’s the difference between a smooth summer and a string of emergency repair calls. Budget a weekend (or hire a handyman for a half-day) and work through this list before the heat arrives. Your future self — and your wallet — will thank you.
