Vapour barrier installation in Westgate, 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 Westgate 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. Westgate is an older SW 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 Westgate, Pine Creek, Alpine Park, Osprey Hill and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Westgate?

Area, penetrations and detailing

Vapour barrier cost in Westgate 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 Westgate 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. Westgate spans a range of build eras, so what is behind the wall differs street to street.

Which side the vapour barrier goes on, and why that is not optional

The warm side, always

In Westgate the barrier goes on the warm side of the insulation — the side facing into the heated Westgate 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 Westgate wall that cannot be corrected without opening the wall back up, which is exactly why we check every Westgate job before anything is covered.

How we install and seal it in Westgate

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 Westgate 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. In Westgate we see everything from original finishes to recent renovations on the same block.

Common vapour barrier situations in Westgate

Character homes in Westgate tend to have settled unevenly over many decades, so wall and ceiling lines are rarely perfectly straight — we work with the house rather than fighting it, patching and skimming so repairs sit flush without chasing a plumb line the original build never had. Same trusted team, same process on every job — on-site quote, fixed price, no surprises.

Why Westgate 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 Westgate.

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.

Fixed price, same-day reply

We cover Westgate and every Calgary quadrant, 7 days a week. Free on-site quotes and a fixed price before any work starts. Housing in Westgate is mixed, which is why we look before we quote rather than after.

FAQ — Vapour Barrier Westgate

Vapour Barrier Westgate: your questions answered

Does my basement development in Westgate 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 Westgate 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 Westgate?
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 Westgate 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 Westgate?
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 Pine Creek, Alpine Park, Osprey Hill and every Calgary quadrant.
Our Westgate home has a mix of plaster and drywall — is that a problem?
Not for us — we treat each surface on its own terms. We match plaster repairs into plaster and drywall repairs into drywall, so you don't end up with a visible seam between the two.
