Building envelope
Brick and block walls, facade restoration, repointing and roofing: we build and repair the envelope that protects your building from Quebec winters.
The envelope (exterior walls, masonry, roof and cladding) keeps water and cold outside. Crumbling brick, a receding joint or a rusted lintel let moisture in: repaired in time, they prevent much heavier work.
I
New construction or restoration, in Montreal, on the North Shore, including Laval, and on the South Shore.
Walls, low walls and facades in brick, concrete block, natural or manufactured stone, with careful, even and lasting workmanship.
Repair of damaged bricks and joints, repointing and surface cleaning: the facade regains its character and its resistance to moisture.
A rusted steel lintel makes the brick above openings swell and crack. We shore, take down the masonry, replace the lintel and relay the brick.
Natural stone veneers, architectural brick and custom finishes that enhance the look of your property.
Load-bearing walls and other damaged masonry work: safe, lasting strengthening, following the engineer's recommendations when the structure is affected.
On older buildings, the mortar is chosen to stay compatible with the original masonry, often lime-based, so it does not damage the brick or stone.
II
The roof takes the rain, the accumulated snow, freeze-thaw cycles and the wind. Well designed, it keeps water out, protects the structure from moisture and contributes to insulation. For commercial and heritage flat roofs, see also our Commercial roofing page.
Two-ply, the preferred solution for flat roofs in Quebec: resistant to frost, snow, impact and UV rays.
A white reflective surface that reduces the heat absorbed and the cooling needs of commercial and industrial buildings.
Durable, resistant to fire, snow and wind, available in several finishes for commercial and industrial buildings.
A regular inspection catches blisters, standing water and open seams early, and extends the life of the roof before a leak.
III
Here is how we classify what you see on your exterior walls during an inspection.
Joints that crumble or recede let water into the wall. Repointing done in time protects the brick.
Stair-step cracks or displaced bricks above openings often point to a rusted, swelling lintel.
Water inside, falling bricks or a bulging wall call for prompt work to make the facade safe.
IV
From inspection to final check, a written process.
V
Solid, careful work, built to last.
In most Montreal boroughs, a permit is required before restoring a facade; it is coordinated with you and its fees are not included in our quotes.

The parts of a building envelope, and what "réfection" (rebuilding) means.

We repair facades, masonry and building envelopes in Montreal, on the North Shore, including Laval, and on the South Shore.

A well-installed and well-maintained membrane lasts several decades; its actual life depends on the system, the slope and the maintenance. An annual inspection catches signs of wear early.
There is no fixed schedule: repointing is needed as soon as the joints crumble, recede or crack. On an exposed facade, a periodic inspection lets you act before water damages the brick.
Standing water, blisters on the membrane, stains or leaks on the ceiling, damp insulation in the attic.
For its reflective surface, which reduces the heat absorbed, its durability and its easy maintenance. It is especially suited to commercial flat roofs.
Yes, in most Montreal boroughs a permit application is required before exterior restoration work. We coordinate it with you.
Yes, if at least one facade has 5 or more storeys above ground. According to the Régie du bâtiment du Québec, the owner must obtain a report verifying that the facades are safe, prepared by a professional, no later than the 10th anniversary of construction, then every 5 years. The owner must also report any dangerous condition to the RBQ without delay and keep a register of the work. We carry out the masonry repairs recommended in the report. Source: RBQ.
Our prices are based on the current wage rates of the Commission de la construction du Québec (CCQ), set by the collective agreements for the sector concerned (residential, institutional and commercial, industrial), plus the materials and equipment specific to each job. Every quote is free, detailed and prepared after a site visit.
Leaks near windows, stains on interior walls, cracked or loose sealants, rusted flashing, drafts or frost on the walls in winter. These signs often point to a water or air tightness problem: a visit finds the cause before we propose any rebuilding.
A bulge is the brick veneer pushing outward. It often means that the ties holding the brick to the wall are corroded, or that water is getting in behind the veneer. Have it assessed quickly: depending on the condition of the wall, the affected section is taken down and rebuilt with new ties, on an engineer's advice when needed.
