Products that are fine in cold
Fiber cement (James Hardie), engineered wood (LP SmartSide), steel and aluminum all install fine in cold weather. The boards don't care about temperature; they're cut and nailed the same way.
Vinyl is the exception
Vinyl gets brittle below about -5°C. Cut it cold and it cracks. Nail it tight on a cold day and it buckles in July because vinyl expands a lot with heat. We can install vinyl on mild winter days, but we won't do it in a deep freeze, and we leave extra room for expansion if we're installing cold.
What has to wait for warmer weather
Caulking and paint touch-ups need a few days above freezing to cure. Sometimes we finish the siding in winter and come back in April for the caulking and any touch-up paint. We tell you that up front so there's no surprise.
Snow on site
We need the ground clear enough to set up ladders and scaffolding safely. A foot of snow against the house slows us down and sometimes stops us for a day. Most jobs we can keep moving.
The upside of winter work
Our schedule is more open, so you're not waiting six weeks for a start date. Material pricing is often better. And the house gets sealed up before the spring thaw instead of after.
Our advice
If your siding is failing — water getting in, boards falling off — don't wait for spring. If it's cosmetic and you want vinyl, spring or fall is easier. Either way, call and we'll tell you honestly what makes sense for your house and the month you're calling in.
