As winter approaches, ensuring your home is ready for freezing temperatures, snow, and ice is key to preventing costly damage and staying comfortable. Whether you own a historic New England farmhouse or a modern residence, this winter home maintenance checklist covers everything you need to minimize risks like ice dams, frozen pipes, and heating inefficiencies.
At Octagon Cleaning & Restoration, we help Maine and New Hampshire homeowners prepare for the season with practical tips to protect their homes from the harsh winter elements.
20 Must-Do Tasks to Winterize Your Home
1. Clean Gutters & Ensure Proper Drainage
Clogged gutters can lead to ice dams, which force water back under your roof shingles. Clear leaves and debris by hand, then flush with a hose to confirm water is draining properly. Also, check that water is flowing away from your foundation.
2. Inspect Gutters and Downspouts for Leaks
While cleaning, look for gutter leaks or areas where water is pooling near your home. Improper drainage can result in basement water damage or foundation issues.
3. Seal Exterior Cracks and Gaps
Use weather-resistant caulk on exterior wall cracks, especially around window and door frames. For brickwork, use a masonry sealer.
4. Test for Drafts Inside Your Home
Walk the interior perimeter with an incense stick. If the smoke wavers, you’ve found a draft. Seal gaps with weatherstripping, door sweeps, or caulk to block cold air.
5. Check and Upgrade Insulation
Inspect your attic, basement, and crawlspaces. Adding insulation where it’s lacking is one of the most effective ways to retain heat and lower energy bills.
6. Schedule a Furnace Inspection
Have your furnace professionally inspected and cleaned before the heating season begins. Regular maintenance improves efficiency and reduces the risk of breakdowns.
7. Replace or Upgrade Furnace Filters
Swap out disposable filters monthly, or invest in a reusable electrostatic filter for long-term savings.
8. Inspect and Seal Ductwork
Heat can escape through poorly sealed ducts. Apply metal-backed tape to seal any gaps. While you’re at it, consider professional duct cleaning for better airflow and air quality.
9. Install Storm Windows or Use Insulation Kits
Storm windows provide an extra barrier against the cold. If that’s not feasible, apply affordable plastic window insulation kits for a temporary but effective solution.
10. Schedule a Chimney Sweep
Before lighting the first fire, ensure your chimney is clean and free of creosote buildup to prevent chimney fires and improve ventilation.
11. Clean and Maintain Woodstoves
Regularly remove ash and inspect your woodstove for wear. A clean stove burns more efficiently and lasts longer.
12. Reverse Ceiling Fans
Set your ceiling fans to spin clockwise to circulate warm air down into living spaces.
13. Shut Off and Drain Outdoor Water Lines
Turn off the interior water valve leading to outdoor spigots, open the exterior spigots to drain remaining water, and store hoses indoors to prevent pipe bursts.
14. Insulate Exposed Pipes
Protect pipes in unheated areas like basements, crawlspaces, and garages with foam pipe sleeves to prevent freezing and reduce water heating costs.
15. Test Smoke and Carbon Monoxide Detectors
Replace batteries and test detectors to ensure your family is protected from fire and carbon monoxide hazards during heating season.
16. Keep a Fire Extinguisher Handy
Ensure you have a working fire extinguisher, especially in or near the kitchen.
17. Flush and Adjust Your Water Heater
Drain sediment from your water heater to improve efficiency. Lowering the thermostat to 120°F will reduce energy usage without sacrificing comfort.
18. Install a Programmable Thermostat
Save on heating costs by automating temperature adjustments based on your schedule.
19. Ensure Heating Vents Are Unobstructed
Check each room to make sure furniture or rugs aren’t blocking vents and restricting airflow.
20. Bundle Up Indoors
Layering up with warm clothes and blankets is a simple way to stay cozy and reduce heating expenses.
