Chicagoland homes endure some of the most demanding weather conditions in the country — subzero winters, humid summers, freeze-thaw cycles that crack concrete, and spring storms that test every roof and gutter. Proactive maintenance is not optional here; it is what separates a home that ages gracefully from one that nickel-and-dimes you with emergency repairs.
Here is a comprehensive season-by-season checklist based on what we see most often when servicing homes across the North Shore and Northwest Suburbs.
Spring (March – May)
- Inspect the roof — Look for missing, cracked, or curling shingles after winter ice and snow. Check flashings around chimneys, vents, and skylights.
- Clean gutters and downspouts — Winter debris, leaves, and shingle grit clog gutters every spring. Ensure downspouts direct water at least 4 feet from the foundation.
- Check the foundation — Walk the perimeter and look for new cracks. Ensure the ground slopes away from the house for drainage.
- Service the AC — Change the filter, clean the outdoor condenser unit, and schedule a professional tune-up before the summer rush.
- Inspect windows and doors — Check weatherstripping and caulking. Replace anything dried, cracked, or peeling.
- Test sump pump — Pour water into the sump pit and verify the pump activates and drains properly. Spring rains are when you need it most.
- Power wash exterior — Clean siding, driveway, sidewalks, and patio of winter grime, road salt residue, and mildew.
- Check deck and patio — Look for loose boards, popped nails, and signs of rot. Clean and reseal if the wood no longer beads water.
Summer (June – August)
- Inspect and repair caulking — Bathroom, kitchen, and exterior caulk deteriorates with heat and humidity. Re-caulk any gaps.
- Check attic ventilation — Proper attic airflow prevents heat buildup that damages shingles and raises cooling costs. Ensure soffit and ridge vents are clear.
- Maintain landscaping away from the house — Trim bushes and trees so they do not touch siding or the roof. Vegetation holds moisture against the house.
- Clean dryer vent — Lint buildup is a fire hazard and reduces dryer efficiency. Professional cleaning costs $100 to $150.
- Test smoke and CO detectors — Replace batteries and test every detector. Replace units older than 10 years (smoke) or 7 years (CO).
- Touch up exterior paint — Address peeling or bare spots before sun and rain cause further damage.
Fall (September – November)
- Clean gutters again — After leaves fall, clean gutters and downspouts a second time. This is the most critical gutter cleaning of the year for preventing ice dams.
- Service the furnace — Change the filter, schedule a professional inspection and tune-up, and verify the thermostat works correctly.
- Winterize outdoor faucets — Disconnect hoses, close interior shutoff valves, and open outdoor spigots to drain. Frozen pipes burst and cause thousands in damage.
- Seal driveway cracks — Water enters cracks, freezes, and expands — turning small cracks into big ones. Fill cracks before the first freeze.
- Insulate and weatherstrip — Add weatherstripping to doors and windows. Check attic insulation depth — Chicagoland homes should have R-49 or better.
- Reverse ceiling fans — Set fans to spin clockwise on low speed. This pushes warm air down from the ceiling, reducing heating costs.
- Flush the water heater — Drain a few gallons to remove sediment buildup. This extends the life of the unit and improves efficiency.
Winter (December – February)
- Monitor for ice dams — Icicles hanging from the eaves can indicate ice dams. Proper attic insulation and ventilation prevent them. If dams form, address the cause in spring.
- Check for drafts — On a cold windy day, feel around windows and doors for cold air. Address with weatherstripping, caulk, or window film.
- Keep the furnace filter clean — Heavy winter use means monthly filter checks. A clogged filter makes your furnace work harder and costs more.
- Protect pipes in cold zones — Insulate pipes in the garage, crawl space, and along exterior walls. Open cabinet doors under sinks on extremely cold nights.
- Clear snow from vents — Ensure furnace exhaust vents, dryer vents, and bathroom exhaust vents are not blocked by snow drifts.
- Plan spring projects — Winter is the best time to get estimates and schedule spring work. Contractors are less busy and may offer better pricing.
