Winterization is the process of preparing a home for the harsh conditions of winter, usually performed in the fall before snow and excessive cold arrive. Here in the Albuquerque area, our nights can drop well below freezing even when the days are mild — which makes winterization easy to overlook. Getting ahead of it protects against damage from burst water pipes and heat loss through gaps in the building envelope.

Building Envelope

Leaky window frames, door frames, and electrical outlets let warm air escape outdoors. Feel for drafts with your hand, or watch for horizontal smoke from a burning incense stick near seams and edges. Air leaks can usually be sealed with insulation tape or caulk.

Insulation

Because hot air rises, a disproportionate amount of heat is lost through the attic. Adequate attic insulation — about 12 inches in cold climates — keeps warm indoor air from escaping. Storm doors and windows add another layer of protection.

Heating System

  • Test the furnace by raising the thermostat — if it doesn't respond quickly, it may need service.
  • Replace the air filter at least once every season of operation.
  • If your furnace uses an oil or propane tank, make sure the tank is full before the cold hits.

Plumbing System

All exposed water pipes in cold, unoccupied areas — attics, garages, and crawlspaces — should be insulated with foam or fiberglass pipe insulation. The water supply to exterior spigots should be shut off from inside and drained, and sprinkler systems should be purged of remaining water with compressed air to prevent cracking.

Chimney & Fireplace

Check the chimney for nesting animals, make sure the damper opens and closes easily, and have a chimney-cleaning professional inspect and clean it if it hasn't been serviced in several years. Keep the damper closed when the fireplace isn't in use — an open damper can let a surprising amount of warm air escape.

Roof & Gutters

Clear leaves and debris from gutters so trapped water doesn't freeze and form ice dams, which can damage gutters and lead to leaks and mold growth. Replace any missing shingles before winter weather arrives.

Leaving a Home Unoccupied This Winter?

If a property will sit vacant, drain all water from indoor and outdoor plumbing, empty toilets completely, leave faucets open, and unplug non-essential appliances. Homes with the heat shut off need this extra attention to avoid catastrophic damage from frozen pipes.

Bottom line: a little preventative maintenance in the fall goes a long way toward protecting your home — and your wallet — through a New Mexico winter. If you'd like a professional set of eyes on your home's readiness, Desert Sky Inspections is happy to help.
