The 7 Absolute Must‑Do’s to Prepare Your Home for Winter

Built for Idaho homeowners. Engineered to prevent water damage, mold growth, storm losses, and freeze‑related failures.

1. Winterize Exterior Water Sources & Irrigation Systems

Exterior water systems freeze first — and they’re responsible for a huge percentage of winter water losses.

Do this:

• Disconnect hoses and drain all spigots.
• Shut off irrigation supply lines and complete a full sprinkler blowout.
• Install insulated faucet covers.

A frozen hose bib can rupture the interior wall pipe and flood a home in minutes.

2. Clean Gutters & Downspouts to Prevent Ice Dams

Ice dams push melting snow backward under shingles, causing roof leaks, attic mold, and interior water damage.

Do this:

• Clear gutters and downspouts before snowfall.
• Ensure downspouts drain 3+ feet away from the foundation.
• Improve attic ventilation to stabilize roof temperatures.

This is one of the most common winter water‑intrusion sources Restoration Pro sees.

3. Inspect Your Roof & Remove Hazardous Tree Limbs

Winter storms bring heavy snow loads, ice, and wind — all capable of causing structural damage.

Do this:

• Replace missing or damaged shingles.
• Trim overhanging branches that can snap under snow.
• Document your roof condition for insurance.

Storm‑related roof punctures often lead to secondary mold growth if not addressed quickly.

4. Seal Air Leaks & Improve Insulation to Prevent Moisture & Mold

Cold air infiltration creates condensation pockets — perfect environments for mold.

Do this:

• Seal gaps around windows, doors, sill plates, and attic penetrations.
• Add insulation to attics and crawlspaces.
• Maintain proper ventilation to prevent moisture buildup.

Moisture + cold surfaces = winter mold growth behind walls.

5. Service Heating Systems & Reduce Fire‑Risk Appliances

Winter fires spike due to overworked heating systems and space heaters.

Do this:

• Schedule a furnace inspection.
• Replace filters every 30–60 days.
• Clean fireplaces, chimneys, and dryer vents.

Fire damage often leads to secondary water damage from suppression efforts.

6. Prepare for Storm Power Outages & Emergency Water Shutoff

Storms and freeze events often cause sudden outages — and homeowners must act fast to prevent damage.

Do this:

• Locate and label your main water shutoff valve.
• Keep flashlights, batteries, and a backup heat source accessible.
• Store Restoration Pro’s emergency number in your phone.

Knowing your shutoff valve location can prevent thousands of gallons of water loss.

7. Protect Your Home’s Foundation & Drainage System

This is the strongest replacement for the pipe‑insulation item — and it’s a major winter damage prevention step homeowners overlook.

Do this:

• Ensure soil slopes away from the home to prevent winter pooling.
• Clear debris from window wells and foundation vents.
• Install or test sump pumps in basements or crawlspaces.

Poor drainage leads to winter seepage, foundation leaks, and mold growth — especially during freeze‑thaw cycles.

Restoration Pro Takeaway

These seven steps dramatically reduce the risk of water damage, mold growth, storm damage, and freeze‑related losses — the exact issues Restoration Pro resolves every winter across the Treasure Valley and McCall.
