Denver winters aren't the harshest in the country, but they're deceptive. Sunny 50-degree afternoons can drop to single digits overnight, and that freeze-thaw cycle is exactly what stresses a home. Getting ready isn't about one big project — it's a short list of small, high-value steps done before the cold sets in.
Seal the leaks first
Heat escapes through the smallest gaps, and in a dry, windy climate that adds up quickly on your bill. Weather-sealing is the cheapest, highest-return winter task there is.
- Add or replace weatherstripping around doors and windows.
- Install door sweeps on any exterior door with a visible gap.
- Caulk gaps where pipes, vents, and wiring pass through exterior walls.
- Check the attic hatch and outlets on exterior walls — common hidden drafts.
Winterize water and irrigation
Frozen water is a home's most expensive winter enemy. In Colorado, a blown-out sprinkler system and protected exterior lines are non-negotiable before the first hard freeze.
- Have your sprinkler system blown out with compressed air — standing water in the lines will crack them.
- Shut off and drain exterior spigots; disconnect all hoses.
- Insulate exposed pipes in the garage, crawlspace, and along exterior walls.
- Know where your main shut-off is — before you need it at 2 a.m.
Ready the roof and gutters
Clean gutters are your defense against ice dams — the ridges of ice that form when clogged or poorly drained water refreezes at the roof's edge and forces melt back under the shingles. Clear them out, make sure downspouts carry water well away from the foundation, and fix any loose shingles while the roof is still dry.
Tune the heat before you need it
Furnaces almost always fail on the coldest night of the year, when every HVAC company in town is slammed. A fresh filter and a pre-season heating check are cheap insurance against a cold, expensive emergency. If tackling this list feels like a weekend you don't have, our seasonal maintenance service handles the whole walk-through in one visit — and leaves you with a written record of what was done.
