Winter in Whatcom County can be unpredictable. While temperatures may stay mild for much of the season, sudden cold snaps can catch homeowners off guard: leading to frozen pipes, water damage, roof leaks, and costly repairs.
The good news? A little preparation goes a long way. Taking time to winterize your home before the next freeze can help prevent emergencies and protect your property.
Use this winter home maintenance checklist to stay ahead of cold weather and avoid common winter damage.
1. Insulate Exposed Pipes
One of the most common causes of winter water damage is frozen pipes.
Why it matters:
- Water expands as it freezes, causing pipes to crack or burst
- Damage often isn’t discovered until pipes thaw and begin leaking
What to do:
- Insulate pipes in crawl spaces, basements, garages, and exterior walls
- Use foam pipe sleeves or heat tape where necessary
- Pay extra attention to pipes near exterior walls
2. Disconnect and Drain Outdoor Hoses
Outdoor plumbing is especially vulnerable during cold snaps.
Why it matters:
- Water left in hoses or outdoor faucets can freeze and back up into interior pipes
What to do:
- Disconnect hoses completely
- Drain and store hoses indoors
- Shut off and drain exterior water lines if possible
3. Seal Drafts Around Doors and Windows
Cold air infiltration makes your home harder to heat and can contribute to frozen pipes.
Why it matters:
- Drafts increase energy costs
- Cold air can freeze plumbing near exterior walls
What to do:
- Replace worn weather stripping
- Caulk gaps around windows and doors
- Check garage doors and access points
4. Clean Gutters and Downspouts
Clogged gutters can create serious winter moisture issues.
Why it matters:
- Trapped water can freeze, causing ice dams
- Ice dams push water under roofing materials, leading to leaks
What to do:
- Remove leaves and debris before freezing temperatures
- Ensure downspouts direct water away from the foundation
5. Inspect Your Roof for Damage
Small roofing issues become big problems in winter.
Why it matters:
- Loose or damaged shingles allow melting snow to enter your home
- Moisture intrusion can go unnoticed until significant damage occurs
What to do:
- Look for missing or damaged shingles
- Check flashing around chimneys and vents
- Address issues before freezing weather hits
6. Test Your Sump Pump (If You Have One)
Winter storms and melting snow can overwhelm sump pumps.
Why it matters:
- A failed sump pump can lead to basement flooding
- Flooding often occurs during power outages
What to do:
- Test your sump pump before winter
- Consider a battery backup system
- Make sure discharge lines aren’t blocked or frozen
7. Keep Your Home Warm, Even When You’re Away
Turning the heat too low is a common winter mistake.
Why it matters:
- Pipes can freeze even if you’re not home
- Damage often occurs while homeowners are away or asleep
What to do:
- Keep your thermostat set to at least 55°F
- Open cabinet doors under sinks to allow warm air circulation
- Have someone check your home if you’ll be away during cold weather
8. Know Where Your Main Water Shut-Off Is
In an emergency, time matters.
Why it matters:
- Quickly shutting off water can prevent extensive flooding
- Many homeowners don’t know where their shut-off valve is located
What to do:
- Locate your main water shut-off
- Make sure it turns easily
- Show all household members where it is
9. Trim Trees and Branches Near Your Home
Winter storms can bring heavy snow, ice, and wind.
Why it matters:
- Falling branches can damage roofs and siding
- Damage can allow water intrusion during storms
What to do:
- Trim branches hanging over your roof or near your home
- Remove dead or weakened limbs before storms arrive
10. Have a Restoration Professional You Can Call
Even with preparation, winter emergencies still happen.
Why it matters:
- Frozen pipes, roof leaks, and flooding require immediate response

- Save the contact information for a trusted restoration company
