March–May
Spring: Renewal & Inspection
Winter's done its damage; spring is when you find out how much.
Check the Roof After Winter
Look for lifted or missing shingles, granule loss in gutters, and ice-dam damage along the eaves.
Clear Gutters and Downspouts
Flush winter debris so spring rain drains away from the foundation, not into it.
Service the AC Before Summer
Replace the filter and schedule a tune-up before the season it works hardest.
Check Foundation and Grading
Look for new cracks and confirm soil still slopes away from the house.
Test the Sump Pump
Pour in a bucket of water and confirm it kicks on and drains properly.
Reseal Exterior Gaps
Check caulking around windows and doors before spring storms find the gaps first.
June–August
Summer: Systems Under Load
Heat and heavy use stress-test everything that runs hardest this time of year.
Inspect the Deck or Patio
Check for loose boards, rusted fasteners, and wood that needs resealing this season.
Check Attic Ventilation
Poor airflow bakes shingles from underneath and raises cooling costs all summer.
Test the Irrigation System
Look for leaks, clogged heads, and water pooling near the foundation line.
Check Siding and Paint
Sun and heat show damage first — look for cracking, fading, or warping.
Clean the Dryer Vent
A summer's worth of use builds lint fast; a blocked vent is a fire risk.
Schedule a Pest Check
Warm months are peak season for termites and carpenter ants near the foundation.
September–November
Fall: Prep & Seal
Every gap you seal now is a gap winter won't find for you.
Inspect the Chimney and Flue
Have it checked and cleaned before the season's first fire, not after.
Winterize Outdoor Faucets
Disconnect hoses and shut off exterior water lines before the first hard freeze.
Service the Furnace
Replace the filter and schedule a tune-up before the season it works hardest.
Seal Drafts and Gaps
Weatherstripping now is cheaper than a winter's worth of heating bills.
Clear Gutters Again
One more pass after the leaves drop keeps winter meltwater off the roofline.
Check Attic Insulation
Thin or settled insulation is one of the most overlooked heat-loss points.
December–February
Winter: Monitor & Protect
Less to do, more to watch — small monitoring habits prevent big winter repairs.
Watch for Ice Dams
Ridges of ice at the eaves signal heat loss and a risk of water backing up under shingles.
Check for Drafts Indoors
Cold spots near outlets and baseboards often point to gaps worth sealing.
Test Smoke and CO Detectors
Heating season raises carbon monoxide risk — test detectors and replace batteries now.
Protect Pipes From Freezing
Let faucets drip and open cabinet doors on the coldest nights of the year.
Inspect the Attic After Storms
Snow load and wind can loosen roofing that won't show damage until spring.
Plan Next Year's Projects
Winter's the season to gather quotes before spring's contractor calendars fill up.
