Reactive maintenance — fixing things after they fail — is always more expensive than proactive maintenance. The problem is most homeowners don't have a systematic way to stay ahead of the curve. This is the checklist I've developed working on homes across Southeast Michigan for years. It's organized by season because our climate really does create different problems at different times of year.
Fall (September–November) — The Most Important Season
Fall is your window to prepare before freeze-up. Repairs are easier and materials cure better in mild temperatures. Don't skip these:
- Caulk all exterior penetrations — wherever pipes, wires, or vents exit the building. Caulk shrinks over time; missing the fall window means a full winter of air infiltration.
- Inspect door and window weatherstripping — compress the weatherstripping in place and check for flat spots. Replace anything that's lost its spring.
- Check exterior door thresholds and sweep seals — run your hand at the base of each exterior door. Any cold air? Fix it before December.
- Clean and seal wood decks — if the deck surface repels water (water beads up), the sealer is still working. If water soaks in immediately, it needs a fresh coat before winter.
- Ensure proper attic ventilation — inadequate ventilation leads to ice dams. Check that soffit vents aren't blocked by insulation and ridge vents are clear.
- Shut off exterior hose bibs and drain them — this is not optional in Michigan. Frozen hose bibs split, and the damage often shows up on the other side of the wall inside.
Winter (December–March) — Monitor and React
Most major work can't happen in winter, but there are things to watch:
- Ice dam patrol — heavy, uniform snowfall is less concerning than icicles forming at the eaves. Significant icicles indicate heat escaping through the roof and ice dam formation. Water backing up under shingles is the expensive consequence.
- Check for frost on interior walls or windows in unheated spaces — garages, enclosed porches, mudrooms. Frost means condensation is accumulating and will cause damage over the season.
- Inspect visible pipe runs in cold zones — below sinks on exterior walls, in basement areas near the foundation. Foam pipe insulation is cheap insurance.
Spring (March–May) — Assess the Winter's Damage
- Walk the perimeter and look at caulk, paint, and wood — the freeze-thaw cycle opens gaps every year. Do this while you can still act before summer humidity arrives.
- Check downspout extensions and grading — water should drain away from the foundation. After a wet winter, soil may have settled and directed water toward the house.
- Inspect deck boards for frost heave or fastener movement — boards that were tight in fall sometimes have gaps or raised fasteners after winter. Address these before summer barefoot traffic.
- Look for signs of ice dam damage on interior ceilings — staining along exterior walls or at peak areas of the ceiling. Better to find and address these in spring than to discover active mold in fall.
Summer (June–August) — Humidity and Pest Season
- Treat wood trim on east and west-facing facades — these get the most direct sun exposure leading to faster paint failure.
- Inspect and caulk where different materials meet — window flanges to siding, siding to trim boards, trim to foundation. This is when the wood is driest and caulk adheres best.
- Check crawl space or basement moisture levels — a dehumidifier running in the basement during humid summers is often the difference between a dry basement and one that develops long-term moisture issues.
The Payoff
Homeowners who stay on top of this kind of seasonal maintenance genuinely experience fewer major repairs. The problems that turn into $5,000–$15,000 emergencies almost always showed minor symptoms years earlier.
