The Fall Home Maintenance Checklist for Michigan Homeowners

If you've lived in Michigan more than a year, you already know what the window looks like: a few weeks in late September and October where it's cool enough to work outside comfortably but warm enough that the ground isn't frozen and the contractors aren't slammed with emergency calls. That's your window. Here's what to do with it.

I've organized this by urgency — the first section is the stuff that can cause serious damage if you miss it, the second is maintenance that makes winter easier, and the third is the planning you can do now for spring projects.

Category 1: Do this before the first freeze

Clean and inspect your gutters — after the leaves drop

Gutters clogged with leaves back up water against the fascia and, in Michigan winters, cause ice dams. An ice dam is a ridge of ice at the roof edge that forces meltwater back up under the shingles. The damage from a bad ice dam — insulation, drywall, sometimes framing — is expensive and avoidable.

Time your gutter cleaning for after most of the leaves have fallen (late October in most of Oakland County). Cleaning them in mid-October just means doing it again in two weeks. While you're up there or hiring someone, check that all downspouts are clear and directing water at least 4–6 feet away from the foundation.

Check your grading and drainage

The ground around your foundation should slope away from the house — about 1 inch per foot for the first 6 feet. After summer, soil settles. Look for low spots against the foundation that could pool water. Fix them with topsoil before the ground freezes, because once it freezes you can't grade anything until spring — and a whole winter of water sitting against your foundation is a basement moisture problem in progress.

Service your furnace before you need it

HVAC companies are backed up in November when everyone turns the heat on for the first time and realizes something's wrong. Schedule your annual furnace tune-up in September or early October. A technician will clean the heat exchanger, check for carbon monoxide issues, test the safety controls, and replace the filter. A furnace tune-up typically runs $80–$130 in Oakland County and can catch a developing problem before it becomes an emergency.

Also: replace your furnace filter now if you haven't in the last 3 months. A clogged filter makes the system work harder, shortens equipment life, and degrades air quality all winter.

Shut off and drain exterior hose bibs

If your exterior faucets don't have frost-free shutoffs, you need to turn off the interior shutoff valve for each one and open the exterior faucet to let it drain. A hose bib that freezes with water in it will split the pipe behind the wall — a repair that typically costs $200–$400 and usually happens on the coldest weekend of the year.

If you're not sure whether you have frost-free bibs, look for a handle that sticks out 6–8 inches from the wall rather than being flush. When in doubt, shut off the supply inside.

Test your sump pump

Autumn rains and snowmelt put serious demand on sump pumps in spring, but fall is the right time to test yours — while you have time to replace it if it fails. Pour a bucket of water slowly into the pit and watch the float rise. The pump should kick on automatically and evacuate the water. If it doesn't, or if it sounds labored, replace it now. A sump pump replacement is a $200–$500 project when done proactively; an emergency replacement after a flooded basement is a much more expensive day.

Category 2: Maintenance that makes winter easier

Caulk and weatherstrip before heating season

Check the caulk around every window and door frame on the exterior. Caulk shrinks over time, especially through Michigan's freeze-thaw cycles. A failed caulk joint is both an air leak and a potential water entry point. Re-caulking is a DIY-friendly job — a tube of exterior caulk runs about $8 and the work takes an afternoon. Do it while temperatures are above 50°F, because caulk won't cure properly in the cold.

While you're at it, check the weatherstripping on all exterior doors. Close the door on a piece of paper — you should feel resistance when you pull it out. If the paper slides freely, the weatherstrip needs replacing.

Check attic insulation and ventilation

A poorly insulated attic drives up heating bills all winter and contributes to ice dams on the roof. The recommended insulation level for Michigan attics is R-49 to R-60. If you can see the tops of your floor joists, you need more insulation. Adding blown-in insulation to an attic is typically $1,500–$3,000 and one of the highest-ROI improvements you can make for energy efficiency.

Also check that your attic vents (soffit and ridge) are clear and not blocked by insulation. Proper airflow prevents moisture buildup and reduces ice dam formation.

Reverse your ceiling fans

Most ceiling fans have a small switch on the motor housing that reverses the blade direction. In winter, run them clockwise on low speed — this pushes warm air that collects at the ceiling back down along the walls without creating a wind chill. It's a free way to reduce heating costs in rooms with high ceilings.

Drain and store outdoor equipment

Drain garden hoses completely and store them indoors — rubber degrades quickly through freeze-thaw cycles. Drain and stabilize gasoline in lawn equipment, or run the tank dry before storage. Drain and cover patio furniture or move it inside. Cover air conditioning units to protect the condenser from debris (not strictly necessary with modern units, but it keeps leaves out of the fins).

Category 3: Plan now for spring projects

Fall is the right time to book contractors for spring work — not spring. The best contractors in Oakland County fill their calendars during winter. A homeowner who calls in April looking for a May start is often looking at July at the earliest.

Even if you're not ready to sign a contract in October, getting on a contractor's radar and having a scope conversation now puts you ahead of the spring rush.
