Vapour barrier installation in Riverview, sealed before the board goes on
A vapour barrier is one of the few things in a 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 Riverview 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. Riverview is a Cochrane community where reno, repair and finishing drywall are common, so basement development and the occasional upgrade where older insulation has settled or thinned are common here. We cover Riverview and all of Cochrane, 7 days a week.

What affects the cost of vapour barrier installation in Riverview?
Area, penetrations and detailing
Vapour barrier cost in Riverview 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 Riverview 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. Where Riverview still has stipple, we check how many coats are on it before deciding to match or remove.
Which side the vapour barrier goes on, and why that is not optional
The warm side, always
In Riverview the barrier goes on the warm side of the insulation — the side facing into the heated Riverview room. That is what stops indoor moisture from travelling into the wall cavity and condensing when it reaches cold framing.
What goes wrong when it is reversed
A barrier installed on the cold side traps moisture inside the assembly instead of keeping it out. It is one of the few mistakes in a Riverview wall that cannot be corrected without opening the wall back up, which is exactly why we check every Riverview job before anything is covered. Removal is a frequent Riverview request, and the age of the ceiling decides how that work is approached.
How we install and seal it in Riverview
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 Riverview 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 jobs that were started by someone else.

Why Riverview 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 Riverview.
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.

Riverview spans a range of build eras, so what is behind the wall genuinely differs street to street — which is why we look before quoting the vapour barrier installation rather than after.
Where Riverview still has stipple, we check how many coats are already on it before deciding whether to match it or take it back.
Removal is a frequent request in Riverview, and the age of the ceiling decides how the work is approached rather than how it is priced.
FAQ — Vapour Barrier Riverview
Vapour Barrier Riverview: your questions answered
Does my basement development in Riverview 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. We confirm what your specific assembly needs on the site visit rather than guessing from the plan.
Which side of the insulation does the poly go on in a Riverview home?
The warm side — the side facing into the heated room. It is the detail that gets reversed most often, and it is not correctable once the wall is boarded.
Do you seal the outlet boxes and vents in Riverview?
Yes — every outlet, switch box, vent and pipe penetration gets sealed individually. Poly hung over open boxes looks finished and does not work.
Do I still need a vapour barrier in Riverview if I have spray foam?
Sometimes not — some spray foam assemblies act as their own barrier, and adding poly over them can be the wrong call. It depends on the product and the thickness, so we confirm on site instead of assuming.
Can you do the vapour barrier and the drywall together in Riverview?
Yes — insulation, vapour barrier and boarding as one job is the most common way we do it, and it means one crew is responsible for what ends up behind the wall. We also cover Cochrane, Sunset Ridge, Heritage Hills and the Cochrane area.
Do you provide free quotes in Riverview?
Yes — we come out to your Riverview home, look at the work and give you a real, fixed on-site price. No guessing after.
