How to Winterize Your Cape Cod Home

Cape Cod winters are no joke. Between the nor'easters, salt air, and freezing temperatures, your home takes a serious beating from November through March. The good news? A little preparation in the fall can save you thousands in repairs — and keep your family warm all season long.

Here's what our home improvement team recommends every Cape Cod homeowner do before the first frost hits.

Frozen pipes are one of the most common — and costly — winter emergencies on the Cape. When water freezes inside a pipe, it expands and can burst, causing major water damage.

What to do:

• Insulate exposed pipes in unheated spaces like basements, crawl spaces, and garages
• Disconnect and drain outdoor hoses
• Know where your main water shutoff valve is located
• If you're leaving for an extended period, keep the heat at a minimum of 55°F

For vacation homes and rental properties, consider installing a smart thermostat with remote monitoring so you can check the temperature from anywhere.

Cape Cod homes — especially older ones — are notorious for drafts. Cold air sneaking in around windows, doors, and electrical outlets can spike your heating bill significantly.

Where to check:

• Around window and door frames (use a candle to detect airflow)
• Attic hatch openings
• Electrical outlets on exterior walls
• Where pipes and wires enter the home

Weatherstripping and caulk are inexpensive fixes that make a big difference. For larger gaps, expanding foam sealant works well.

Don't wait until the first cold snap to find out your furnace isn't working. Schedule a heating system tune-up in September or October before HVAC companies get slammed with emergency calls.

Annual maintenance checklist:

• Replace furnace filters (do this every 1–3 months during heating season)
• Bleed radiators if you have a hot water heating system
• Test your thermostat
• Check carbon monoxide detectors and replace batteries

Leaves and debris clog gutters, causing water to back up and freeze. Ice dams — those ridges of ice that form at the roof's edge — can force water under your shingles and into your home.

Clean gutters in late November after most leaves have fallen. Make sure downspouts direct water at least 6 feet away from your foundation.

The combination of heavy snow loads and freeze-thaw cycles is tough on roofs. Before winter, take a look (or hire someone to look) for:

• Missing or damaged shingles
• Cracked or deteriorating flashing around chimneys and vents
• Sagging areas that could indicate structural issues

Catching a small problem now is far less expensive than dealing with a leak mid-January.

Cape Cod is no stranger to powerful nor'easters. Make sure you're ready:

• Stock an emergency kit: flashlights, batteries, bottled water, non-perishable food
• Know how to manually open your garage door if the power goes out
• Trim tree branches that hang over your roof or power lines
• Have a generator serviced and ready if you own one

Your deck, patio furniture, and landscaping need attention before winter too.

• Clean and seal your deck (fall is a great time — see our deck maintenance guide)
• Store or cover outdoor furniture
• Drain and store garden hoses
• Shut off and drain irrigation systems
• Mulch garden beds to protect plant roots

Winterizing a home is a lot of work, and some tasks — like roof inspections, pipe insulation, and weatherproofing — are best left to professionals. Our home improvement team has been helping Cape Cod homeowners prepare for winter for years.
