Most exterior contractors specialize in one or two trades. At Strasser & Lang, we handle every facet of your building's exterior. This Lake Superior new build is a perfect example of why that matters.

Roof. Siding. Stone Veneer. Soffit. Fascia and Eavestrough. Every element of this home's exterior, completed by one crew under one contract and one standard of quality.

No juggling multiple companies. No gaps between trades. No finger-pointing when something isn't right. Just one team that owns the entire job, from the first consultation to the final walkthrough.

When every part of your home's exterior is installed by the same experienced crew, everything fits together the way it should. That's the full envelope advantage, and it's something only Strasser & Lang delivers in Northwestern Ontario. 🏠

Another siding job done right. This one out at a camp on One Island Lake.

We installed Celect Board & Batten siding in the colour Grove. It's a composite product that looks sharp, holds up against the elements, and doesn't ask for much once it's on. For a camp that takes a beating from Northwestern Ontario winters, that matters.

This was a big one. Full siding wrap, soffit, fascia, all the flashing and aluminum capping to tie it together. The kind of job where every detail has to line up because there's nowhere to hide on a build like this.

Our crew worked through the winter to get it done. Scaffolding in the snow, temps well below zero, and the same standard of work we'd expect on any job regardless of the conditions. That's just how we operate.

Swipe through to see the progress and the finished product. The result speaks for itself.
