Does my basement development in Maple Ridge need a vapour barrier?

Almost always, yes -- exterior basement walls in our climate need a barrier on the warm side of the insulation before drywall, and Maple Ridge is no exception. We confirm what your specific Maple Ridge assembly needs on the site visit rather than guessing from the plan.

Which side of the insulation does the poly go on in a Maple Ridge home?

The warm side -- the side facing into the heated Maple Ridge room. It is the detail that gets reversed most often in Maple Ridge homes, and it is not correctable once the wall is boarded.

Do you seal the outlet boxes and vents in Maple Ridge?

Yes -- every outlet, switch box, vent and pipe penetration in the Maple Ridge wall gets sealed individually. Poly hung over open boxes in a Maple Ridge wall looks finished and does not work.

Do I still need a vapour barrier in Maple Ridge if I have spray foam?

Sometimes not -- some spray foam assemblies act as their own barrier, and adding poly over them in a Maple Ridge wall can be the wrong call. It depends on the product and the thickness, so on a Maple Ridge job we confirm on site instead of assuming.

Can you do the vapour barrier and the drywall together in Maple Ridge?

Yes -- insulation, vapour barrier and boarding as one job is the most common way we run Maple Ridge work, and it means one crew is responsible for what ends up behind the wall. We also cover Rangeview, Ricardo Ranch, Belvedere and every Calgary quadrant.

Vapour barrier installation in Maple Ridge, sealed before the board goes on

A vapour barrier is one of the few things in a Maple Ridge build that is completely hidden and completely unforgiving -- once the drywall is on, a torn sheet or an unsealed outlet box stays that way for the life of the wall. In Maple Ridge we install and seal 6 mil poly over the insulation on the warm side, lapped at the seams and sealed at every penetration, before any board goes up. Maple Ridge is an older SE Calgary community where settling cracks, aging texture and the occasional plaster repair come up, so attic top-ups and wall insulation upgrades are common here alongside basement development, since original insulation levels are often below current standards. We cover Maple Ridge, Rangeview, Ricardo Ranch, Belvedere and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Maple Ridge?

Area, penetrations and detailing

Vapour barrier cost in Maple Ridge depends on the wall and ceiling area being covered, the number of penetrations that need sealing — outlets, vents, pipes and light boxes — and how much detail work the rim joist and window returns need. We measure the space and give a fixed price before we start.

Usually priced with the insulation

Most Maple Ridge vapour barrier work is quoted together with the insulation and the boarding that follows it, because it is the same crew and the same visit.

Which side the vapour barrier goes on in a Maple Ridge home, and why that is not optional

The warm side, always

In Maple Ridge the barrier goes on the warm side of the insulation — the side facing into the heated Maple Ridge room. That is what stops indoor moisture travelling into a Maple Ridge wall cavity and condensing when it reaches cold framing.

What goes wrong when it is reversed

A barrier on the cold side traps moisture inside the assembly instead of keeping it out. It is one of the few mistakes in a Maple Ridge wall that cannot be corrected without opening the wall back up, which is exactly why we check every Maple Ridge job before anything is covered. In Maple Ridge we see everything from original finishes to recent renovations on the same block.

How we install and seal it in Maple Ridge

Hung, lapped and sealed

We run the poly in the largest sheets the space allows to keep seams to a minimum, lap every seam over a stud or joist rather than in open cavity, and seal it — a stapled overlap on its own is not a seal.

The penetrations are the job

Outlet and switch boxes, bath fans, dryer vents, plumbing stacks and pot lights each get sealed individually in your Maple Ridge home. Poly on the walls with open boxes behind it is not a working vapour barrier, and it is the single most common thing we find on Maple Ridge jobs that were started by someone else. In Maple Ridge we see everything from original finishes to recent renovations on the same block.

Common vapour barrier situations in Maple Ridge

In Maple Ridge, we see plenty of settling-related drywall cracks in Maple Ridge that trace back to the original foundation curing decades ago — cosmetic at this point, and a straightforward repair once we've confirmed there's no ongoing movement. One fixed price after an honest on-site look, and the job done right the first time.

Why Maple Ridge homeowners have us do the vapour barrier

We are the ones boarding over it

As a drywall company we install the barrier the way we want to board over it, because we are the trade that has to live with what is behind the sheet in Maple Ridge.

Left ready to be looked at

We leave the barrier complete and visible so it can be inspected before the drywall goes on — nothing gets covered until it has been seen.
