Be ahead of costly repairs with this easy guide for Colorado homeowners.

Homeownership on Colorado's Front Range equals four different seasons—and each one comes with its own set of tasks to do if you wish to keep your home safe, efficient, and in working order.

Regardless of whether you're located in Boulder, Lafayette, Longmont, or nearby, this spring home maintenance guide will spare you surprises and protect your investment year-round. It's not doing it all at once—it's getting a jumpstart on the little things before they turn big (and expensive).

______________________________

Spring Maintenance (March–May)

Purpose: Inspect for winter damage and prepare your home for warmer weather.

Inspect your roof for loose or missing shingles: Heavy snow and wind can loosen shingles—catch problems before they turn into leaks.

Clean gutters and downspouts: Clear winter storm debris from gutters and ensure drainage as snow melts and rain rises.

Inspect your siding and paint: Peeling paint or buckled siding can let moisture in—touch up early.

Service your air conditioning: Schedule A/C maintenance before the initial heat wave.

Inspect sprinklers and outside faucets: Inspect for leaks or busted heads after winter freeze-thaw periods.

Re-seal deck or patio surfaces: Spring is the best time to get outdoor living spaces ready for summer use.

Summer Maintenance (June–August)

Goal: Highlight exterior care and energy efficiency.

Clean and check windows/screens: Let the wind in and the critters out—also, clean windows make your space sparkle.

Power-wash siding, decks, and driveways: Remove dirt, mildew, and pollen buildup.

Check attic and crawl space ventilation: Proper airflow keeps heat and humidity under control (and preserves your roof).

Touch up caulking and weather stripping around the home: Keeps bugs out and cool air in on hot days.

Test carbon monoxide and smoke detectors: A quick monthly check keeps your family safe—replace batteries if needed.

Look for pest signs: Ants, wasps, and rodents love warm weather—catch infestations early.

______________________________

Fall Maintenance (September–November)

Goal: Prepare for freezing weather and winter storms.

Clean gutters once more: Leaves falling = clogged gutters. Prevent ice dams and water damage from occurring.

Turn off and drain outdoor faucets and sprinklers: Prevent frozen pipes and costly bursts.

Inspect weather stripping around doors and windows: Seal drafts and save on heating costs.
Service your furnace and replace filters: Beat the rush—book ahead and have it ready to roll.

Chimney inspection (if you have a fireplace): Creosote buildup is a fire hazard—have it drained before initial use.

Stock up on winter supplies: Salt, shovels, snow blower maintenance—it's better to be ready than stranded.

______________________________

Winter Maintenance (December–February)

Goal: Remain warm and prevent cold-weather damage.

Inspect ice dams and icicles: Check roof edges—clear gently if needed to prevent leaks.

Inspect for indoor condensation: Window moisture may be a sign of insufficient ventilation—use fans or a dehumidifier.

Reverse ceiling fans: Adjust blades to spin clockwise to push warm air downward.

Inspect pipes: Leave cabinet doors close to sinks open on cold nights and close garage doors to protect exposed plumbing.

Test your sump pump (if applicable): It may seem inactive, but snowmelt can trigger it—make sure it’s working.
Review your emergency supplies: Make sure flashlights, batteries, and blankets are handy for snowstorms or power outages.

Bonus Tip: Create a Maintenance Calendar

Don't try to accomplish everything all at once. Break up these activities into batches of months and schedule them as if you were making an appointment. We recommend using a recurring reminder on your phone or a posted checklist in your garage or utility closet.
