Window, Door & Siding Replacements

Tighten Up the Building Envelope

Windows, doors, and siding are the parts of your home that take the worst of an Algoma winter, and they are the first place heat escapes once they start to fail. We replace all three — units, trim, flashing, and cladding — as one coordinated scope rather than three separate trades.

Every replacement is fitted and flashed to shed water properly, so the new envelope looks right from the street and performs where you cannot see it.

Exterior siding and window work by Montare Construct

Windows

Full-frame and retrofit replacements, measured, fitted, and flashed so the opening drains instead of holding water.

Doors

Entry, patio, and garage-access doors hung square, weather-sealed, and finished to match the existing trim.

Siding

Vinyl, engineered wood, and board-and-batten cladding installed over a properly detailed weather barrier.

One Crew, One Envelope

The same team handles the opening, the flashing, and the cladding — nobody is blaming the trade before them.
