Living in Wilmette means enjoying tree-lined streets, historic homes, beautiful parks, and proximity to Lake Michigan. But our North Shore climate—cold winters, hot summers, humidity, storms, and lake-effect moisture—means that proactive home maintenance is essential. Whether you own a new construction home near the lake or a charming older property in McKenzie or Indian Hill Estates, a seasonal checklist keeps your home safe, efficient, and protected year-round.

Here is a comprehensive, fact-based Wilmette home maintenance checklist designed to help homeowners prevent costly repairs and maintain long-term property value.

Spring Home Maintenance (March–May)

As the snow melts and temperatures rise, focus on repairs that address winter wear and prepare your home for rainy season.

1. Check the Roof for Winter Damage

Look for:

• Missing shingles

• Curling shingles

• Ice dam damage

• Exposed underlayment

Winter storms and freeze-thaw cycles can shorten a roof’s lifespan, especially on older homes.

2. Inspect Gutters and Downspouts

Spring rainfall in Wilmette is significant. Make sure:

• Gutters are clean.

• Downspouts extend 6–10 feet away from the home.

• Water flows away from the foundation.

This prevents seepage and reduces basement flooding risk.

3. Test the Sump Pump

With spring storms approaching:

• Test the float switch.

• Clear debris.

• Verify the discharge line is flowing freely.

• Check any backup system.

This is crucial for homes near Lake Avenue, Washington, or anywhere with a high water table.

4. Inspect the Exterior Grading

Soil should slope away from your home. Winter shifting can change ground levels, especially around patios or walkways.

5. Service the Air Conditioner

Have a licensed HVAC contractor:

• Clean coils

• Check refrigerant

• Test electrical components

Regular maintenance improves efficiency and prolongs equipment life.

6. Evaluate Trees and Landscaping

Trim branches away from your roof and power lines. Spring storms can bring heavy winds to Wilmette, especially near the lake.

Summer Home Maintenance (June–August)

Summer is the best time to handle exterior projects and preventative updates.

1. Power Wash Siding, Walkways, and Decks

This removes mold, algae, and debris that can build up in humid North Shore summers.

2. Inspect Windows and Doors for Energy Loss

Look for:

• Gaps

• Failing caulk

• Drafts

• Condensation between panes

Energy loss increases cooling costs and indicates air leaks.

3. Clean Dryer Vents

Lint buildup is a fire hazard. Have the entire vent line cleaned annually.

4. Treat Decks and Wood Structures

Apply sealant or stain every 1–3 years depending on exposure. Wilmette’s humidity accelerates wood deterioration.

5. Check Exterior Paint

Peeling or cracked paint exposes siding to moisture. Spot-treat or repaint as needed.

Fall Home Maintenance (September–November)

Prepare for freezing temperatures, heavy snowfall, and winter storms.

1. Clean Gutters and Downspouts Again

Fallen leaves can clog gutters, causing winter ice dams and water infiltration.

2. Schedule a Furnace Inspection

Have a licensed HVAC technician:

• Clean burners

• Inspect heat exchanger

• Replace filters

• Test carbon monoxide levels

Heating systems work hard in Wilmette’s winters—maintenance reduces breakdowns.

3. Seal Exterior Gaps

Caulk around:

• Windows

• Doors

• Siding transitions

• Utility penetrations

This prevents cold drafts, pests, and heat loss.

4. Winterize Outdoor Plumbing

Disconnect hoses and shut off exterior water valves to prevent frozen pipes.

5. Service the Chimney & Fireplace

If you have a wood-burning or gas fireplace, schedule a professional inspection before winter use.

6. Check Snow Removal Equipment

Before the first snowfall, make sure:

• Snowblower starts

• Shovels are in good condition

• Salt is stocked

Winter Home Maintenance (December–February)

Cold temperatures and winter storms are hard on homes across the North Shore.

1. Monitor Ice Dams

Ice dams form when warm air melts roof snow, which refreezes at the edges. This can cause:

• Roof leaks

• Soffit damage

• Mold growth

Use a roof rake or hire a professional for removal.

2. Maintain Indoor Humidity

Aim for humidity between 30–50% to prevent:

• Dry air

• Static

• Wood floor separation

• Window condensation

3. Check for Frozen Pipes

Insulate pipes in:

• Basements

• Crawlspaces

• Exterior walls

Open cabinet doors during extreme cold to allow warm air circulation.

4. Inspect the Attic for Proper Insulation

Good insulation reduces ice dams and heat loss. Look for:

• Uneven insulation

• Exposed joists

• Signs of moisture

5. Test Smoke and Carbon Monoxide Detectors

Heating systems can increase CO risks. Replace batteries every six months.

Year-Round Home Maintenance Essentials

Regardless of the season, keep up with these routine tasks:

✔ Replace HVAC filters (every 1–3 months)

✔ Test GFCI outlets

✔ Inspect water heater for leaks

✔ Keep basement dehumidifiers clean

✔ Check foundation for cracks

✔ Review homeowner’s insurance coverage annually

Staying consistent prevents expensive repairs and increases long-term property value.
