🏠 Home Winterization Guide

Winterization is the process of preparing a home for the harsh conditions of winter. It’s typically done in the fall, before freezing temperatures and snowfall arrive. Proper winterization helps prevent:

• Burst pipes from freezing temperatures
• Heat loss through drafts or poor insulation
• Damage to outdoor systems and structures

🔥 Heating System

Since the heating system sees its heaviest use in winter, inspect it early:

• Raise the thermostat to test the furnace. If it doesn’t respond quickly, it may need repair.
• Replace the air filter at least once per season.
• If your furnace uses oil or propane, fill the tank before winter.

❄️ Cooling System

Shut down and protect cooling components before winter sets in:

• Use a hose to clear debris from the outdoor AC unit.
• Cover the unit with a breathable, waterproof cover to prevent rust and freezing.
• Remove window air conditioners to prevent drafts and internal damage.
• Reverse ceiling fans to rotate clockwise, pushing warm air down from the ceiling.

🪟 Building Envelope

A well-sealed building envelope reduces heat loss and energy costs:

• Check for air leaks around windows, doors, and outlets.
• Test for drafts using your hand or an incense stick.
• Seal leaks with weatherstripping, caulk, or insulation tape.
• Inspect attic insulation—12 inches is recommended for homes in colder climates.
• Install storm doors and windows for added protection.

🧱 Insulation

Proper insulation keeps your home warm and energy-efficient:

• Inspect insulation in attics, basements, and crawlspaces.
• Install additional insulation where needed.

🧱 Chimney & Fireplace

Make sure your fireplace is safe and efficient before winter use:

• Have the chimney inspected and cleaned by a certified professional.
• Ensure the damper opens and closes easily.
• Test for proper airflow—smoke should rise up the chimney.
• Check for animals or debris in the flue.
• Keep the damper closed when not in use to prevent heat loss.
• Install glass doors for added insulation.

🪜 Roof & Gutters

Prevent costly roof and gutter damage from ice and snow:

• Clean gutters and downspouts to prevent ice dams.
• Remove debris such as leaves and pine needles.
• Replace any missing or damaged shingles.

🚿 Plumbing System

Frozen pipes are one of the most common (and costly) winter issues. Prevent them with the following steps:

• Insulate all exposed water pipes in attics, basements, crawlspaces, and garages.
• Use foam or fiberglass insulation sleeves from hardware stores.
• Shut off and drain water to outdoor spigots and sprinkler systems.
• Use compressed air to purge sprinkler lines.
• Maintain a safe indoor temperature, even in unheated areas.
• Homes in cold climates may benefit from plastic plumbing, which is more tolerant of freezing.

🌳 Landscaping

Protect outdoor furniture and decks:

• Cover patio furniture to prevent damage.
• Apply sealant to decks if needed.

🏚️ Winterizing an Unoccupied Home

If a home will be unoccupied during the winter (e.g., seasonal homes or foreclosures), winterization is critical to avoid severe damage:

• Drain all plumbing—including toilets, water tanks, and pumps.
• Pour antifreeze into toilets and plumbing traps.
• Open all faucets and leave them open.
• Unplug all non-essential appliances, including refrigerators.
• If the house will be empty and no electricity is needed, shut off power at the main breaker.

✅ Summary

• Start winterizing in fall, before freezing temperatures arrive.
• Focus on heating, plumbing, insulation, and sealing air leaks.
• Schedule professional inspections when necessary (chimney, furnace, AC, roof).
• Winterization is especially important for homes that will remain unoccupied during cold months.
