A spring walk-around for your home’s paint: what a Michigan winter does, and what to check
Winter leaves its marks on paint in predictable places. A slow walk around the house once the snow is gone tells you what needs a small repair now and what can wait for a full repaint.
Key takeaways
- Freeze–thaw works water into every small gap in paint, caulk and wood, so the damage shows up in spring in the spots where water collects.
- Check the bottoms of trim and doors, window sills, caulk lines, north-facing walls, gutters and the roof edge first.
- Small failures, such as a cracked caulk line or a bare patch of wood, are worth repairing right away before water makes them bigger.
- Wide areas of peeling, chalking or soft wood point to a bigger job that’s best planned for the next painting season.
A spring paint inspection is a slow walk around the house, looking at the spots where winter water does its damage: bottoms of trim and doors, window sills, caulk lines, north-facing walls and the roof edge. Fix small failures like cracked caulk and bare wood promptly, and plan wider peeling or soft wood for the next painting season.
Michigan’s freeze–thaw cycles are tough on exterior paint. Water gets into small cracks, freezes, expands and pries the gaps wider, and repeats the cycle many times a season. The good news is that damage is predictable and easy to spot with a plan. Here’s what to bring, where to look and how to sort what you find.
When should you do the walk-around?
Wait until snow and ice are off the ground and the walls have dried out, usually by mid to late spring. Wet wood looks worse than it is, and some paint defects only show when the surface is dry. In metro Detroit the last spring freeze is typically around late April, and it can come earlier or later, so a freeze after your inspection isn’t unusual.
Pick a dry day with decent light. Early morning or late afternoon sun, striking the wall at an angle, reveals blisters, ripples and raised wood grain that flat midday light flattens out.
Bring a notepad or phone for photos, a small screwdriver or awl to test wood, a flashlight and a pair of binoculars for upper areas. Stay on the ground; there’s no need to climb a ladder to see what you need to see.
What does a Michigan winter do to exterior paint?
Water enters wherever the paint film has opened: hairline cracks, shrunken caulk, bare end grain, gaps at joints. When it freezes it expands, forcing the gap wider, and when it thaws, more water follows. Wood swells and shrinks as it takes on and loses moisture, and a stiff, aged paint film can’t keep up. Repeat that dozens of times and a small crack becomes a peeled patch.
Snow also holds moisture against the house. Drifts against a wall, snow piled on a porch rail or ice at the roof edge keep wood wet for weeks. Lake-effect humidity and wind near Lake St. Clair add to the load. Our guide to why exterior paint peels goes deeper on the mechanics.
Where should you look, and what are you looking for?
Work around the house in one direction and check these spots on each side.
| Spot | What to look for | Why it matters |
|---|---|---|
| Bottoms of trim, doors and posts | Peeling, dark staining, soft wood | Splash and standing water collect here |
| Window sills | Cracks, bare wood, flaking | Sloped surfaces hold water |
| Caulk lines | Gaps, splits, pulled-away edges | Open joints let water into the wall |
| North and shaded walls | Green or black growth, chalky film | Slow to dry, mildew-prone |
| Gutters and downspouts | Sagging, overflow stains, rust | Overflow soaks walls and trim |
| Roof edge, fascia, soffit | Peeling, stains, soft wood | Ice dams and meltwater damage |
| Doors and thresholds | Blisters, cracked finish, bare wood | Sun and weather wear the finish |
Take a photo of anything that bothers you and note the location. A set of photos lets you compare next spring and shows a painter exactly what you mean.
Trim bottoms, sills and joints
Press a screwdriver tip lightly into the wood at the bottom of window and door trim, porch columns and the sill. Sound wood resists. Soft, crumbly wood needs repair before any paint. Look at where trim meets siding, at corners and around windows. Caulk that has split, shrunk or pulled away from one side is no longer sealing, and needs to be cut out and replaced with a paintable sealant.
North and shaded sides
The north side of a house and any wall under trees stays damp and dries slowly. Look for a green, gray or black film. Test it by wiping with a damp cloth; if it comes off, it’s probably dirt or mildew, and our guide to mildew on siding before painting explains how it should be treated. A chalky paint film, which rubs off as a powder on your fingers, means the coating is wearing out. See signs your house needs painting.
Gutters, roof edge and upper walls
Look for sagging gutters, overflow staining down the wall and downspouts that dump against the house. Check the fascia and soffit for peeling or dark patches. A pattern of damage along the eave points to winter water backing up under the roof edge; our guide on ice dams and peeling paint explains the order to fix it in.
Doors, porches and steps
Front doors take sun, rain and ice melt. Look for cracked or blistered finish, bare wood at the bottom edge and a worn threshold. Our front door paint guide covers that surface.
What should you repair now, and what can wait?
A simple triage keeps the list manageable.
Repair now (small and urgent):
- Open or cracked caulk lines around windows, doors and trim joints.
- Small patches of bare wood. Bare wood left open takes on water fast.
- Loose or sagging gutters and downspouts directed at the wall.
- Rusted nail heads that are bleeding stains onto paint.
- Soft spots that can be found early and fixed before rot spreads.
Plan for the next painting season (bigger):
- Wide areas of peeling, bubbling or alligatored paint.
- Chalking or fading across whole walls.
- Rotted trim or fascia that needs replacing.
- Mildew over large areas.
- Brick or stucco problems such as failing mortar or cracks, which are masonry repairs first.
Spring touch-ups are best done with the same type of coating that’s on the wall and when the surface is dry and the temperature fits the label. Primer goes on bare wood, and a spot of topcoat on a bare patch is not a repaint. Check the product label for minimum temperatures, since cold spring nights can fall below them.
When is it time to call a painter?
Call for help when problems are widespread, repeated or structural: peeling across large areas, many soft spots, damage that keeps coming back in the same place or anything that looks like a water problem, not a paint problem. A written scope that separates repairs from painting makes the plan clear.
Planning ahead also helps with timing. If the walk-around shows a full repaint is coming, lining up the work early in the season, before the summer rush, gives the wood time to dry and the weather time to cooperate.
Is there anything to know about lead paint when scraping?
Yes. Homes built before 1978 may contain lead-based paint, and scraping or sanding old paint can release it. The EPA’s Renovation, Repair and Painting (RRP) rule requires certified firms and lead-safe work practices for paid work that disturbs painted surfaces in pre-1978 homes, more than 20 square feet outside. See the EPA’s RRP program page, and our lead paint guide. If you’re unsure, test before you scrape.
How does a careful painter handle what the inspection finds?
If a repair list turns into a repaint, the prep-first steps on our process page are the order the work follows. Bob and Bobby are on every project, the scope is written in plain English, and a final walkthrough with touch-ups closes the job. That’s the order a spring inspection should feed: find the small things, fix them, and plan the large ones.

Questions
When is the right time to inspect exterior paint in Michigan?
Wait until the snow is gone and the walls have dried, usually mid to late spring. Choose a dry day with good angled light so blisters, cracks and raised grain show. A freeze after the inspection is still possible, since the last spring freeze in metro Detroit is typically around late April.
What spots on a house usually fail first after winter?
Water collects at the bottoms of trim, doors and posts, on window sills, along caulk lines, on shaded north walls and along the roof edge. These are the places to check first. Probe the wood with a screwdriver tip; soft wood needs repair before painting.
Can I touch up peeling paint in spring or should I wait?
Small failures, such as cracked caulk or bare wood, are worth fixing right away: scrape to sound paint, spot-prime, and use a paintable sealant. Wide peeling, rot or chalking calls for a full repaint in the next painting season. Follow the label’s minimum temperatures for any product.
