Get Your Home Ready for Winter

A little prep now helps protect your home all winter.

As temperatures drop, it’s easy to focus on the furnace, gutters, and yard cleanup. But your home’s exterior paint deserves a spot on your fall maintenance list, too. A sound paint finish helps protect siding and trim, while worn coatings and failed seals can leave vulnerable areas exposed to moisture.

You don’t necessarily need to repaint your entire home before winter. A careful inspection can help you identify small repairs, address trouble spots, and plan larger projects for suitable weather.

Use this fall painting checklist to get started.

1. Check for peeling or cracking paint

Take a walk around your home and look closely at siding, trim, doors, and window frames. Pay particular attention to exposed wood, horizontal ledges, and places where paint has failed before.

Look for:

• Paint that is lifting, flaking, or curling at the edges.

• Cracks in the painted finish.

• Bare patches of wood or other exposed surfaces.

• Blisters or recurring damage in the same location.

Before touching up a damaged area, determine why the paint failed. Adding another coat won’t solve an underlying moisture problem. Sherwin-Williams identifies damp surfaces and moisture entering through deteriorated joints as possible causes of exterior peeling. Learn about moisture-related paint failure.

Your fall task: Photograph damaged areas and make a repair list. Small, isolated spots may need localized preparation and painting; widespread failure deserves a closer assessment.

2. Clean away dirt and mildew

Dirt, grime, and mildew can make it harder to see the condition of your paint. Cleaning also matters before any touch-up work: new paint needs a properly prepared surface.

Choose a cleaning method appropriate for your siding and existing finish. Follow the surface manufacturer’s guidance and the cleaner’s instructions. Avoid aggressive washing that could damage the coating or force water behind siding.

Start with a small test area, protect nearby landscaping, and allow surfaces to dry thoroughly before painting.

Your fall task: Clean the areas you plan to inspect or repair, including shaded sections and lower trim where buildup is easy to overlook.

3. Inspect caulk around windows, doors, and trim

Even when the paint looks good, deteriorated caulk can leave openings where moisture may enter.

Check appropriate sealed joints for caulk that has cracked, separated, or pulled away. When replacement is needed, choose an exterior sealant compatible with the surrounding materials and your planned paint finish. Follow its preparation, application, and paint-over instructions.

Be selective about where you seal. Some openings serve a drainage or ventilation purpose. Sherwin-Williams specifically advises against caulking overlapping siding joints because doing so can trap moisture. Follow the siding and window manufacturers’ requirements rather than filling every visible gap. Read the exterior caulking guidance.

Your fall task: Identify failed seals around windows, doors, and trim, while keeping intended drainage paths open.

4. Touch up exposed wood

Bare wood deserves attention before winter weather arrives. Look at door frames, window trim, fascia, porch details, and other painted wood surfaces.

A lasting repair involves more than brushing paint over a bare patch. The area may need cleaning, removal of loose coating, sanding, repairs, and a compatible primer before the finish coat goes on. The correct preparation depends on the wood’s condition and the coating system you use.

Match the existing paint’s color and sheen as closely as possible, but remember that older paint can fade. A small touch-up may remain visible; painting an entire trim board or clearly defined section can sometimes create a more consistent appearance.

Your fall task: Prioritize exposed areas and confirm that the wood is sound and dry before recoating.

5. Look for moisture damage before covering it

Peeling paint, stains, and soft wood can be signs that a repair needs to go beyond the painted surface.

Look for discoloration beneath gutters, damaged trim near roof intersections, or repeated paint failure around a window. Inside the home, investigate new water stains before treating them as a cosmetic problem.

The order matters: identify the source, complete the necessary repair, allow the material to dry, and then restore the finish. Paint cannot repair rotten wood or stop an active leak.

Your fall task: Separate cosmetic touch-ups from problems that require a carpenter, roofer, window specialist, or other qualified professional.

6. Check the forecast before scheduling exterior painting

A pleasant afternoon doesn’t automatically create a suitable painting window. Overnight temperatures, surface moisture, humidity, and the possibility of rain or dew also affect the work.

Check the instructions for the specific primer, paint, and sealant you plan to use. Products have different application temperatures and requirements for protection from moisture. Air temperature alone may not tell you whether the surface is ready.

Sherwin-Williams notes that cool evenings and dew can interfere with exterior paint application. Follow the product’s current technical guidance throughout the required drying period. Review exterior application guidance.

Your fall task: Schedule enough suitable weather for preparation, application, and drying. If conditions won’t cooperate, address urgent building repairs and plan the painting for a better window.

7. Decide what needs attention now

Once your inspection is complete, organize your list by priority.

Investigate promptly: Active leaks, soft or deteriorated wood, and recurring moisture damage.

Complete when conditions allow: Failed caulk at appropriate joints, exposed sound wood, and localized coating repairs.

Plan for a future project: Widespread fading, a color change, or a larger repaint when the existing finish remains intact.

This approach helps you focus on the work that protects your home while giving larger projects the preparation and weather they need.
