Jobs step by step

Before, during, after

The same job photographed at each stage: what we found, how we fixed it, and the result.

Covered-deck posts replaced

Posts rotted at the base, under a roof that had to stay up. We shored the roof, replaced the posts with solid cedar and installed an aluminum railing.

Cedar decks and patios

Lakeside cedar shed

A shed built from framing to double doors, facing the lake: framing wrapped in air barrier, then cedar siding.

Questions homeowners ask

Before starting a cedar decks and patios project with us.

Cedar or composite?

Cedar costs less up front, smells great and can be repaired board by board, but needs a treatment every two or three years. Composite costs more and needs nothing. We build both.

My covered-deck posts are rotted. Does it all need rebuilding?

Rarely. We shore the roof with temporary posts, replace the columns with solid cedar on raised bases, and keep the rest.

Do I need a permit for a deck?

In most towns in Vaudreuil-Soulanges and the West Island, yes, as soon as the deck is raised or attached to the house. We provide the drawing.
