Does my basement development in Westmount need a vapour barrier?

Almost without exception, yes: exterior basement walls in Westmount require a barrier on the warm side of the insulation ahead of the drywall. Rather than reading it off the plan, we confirm on site in Westmount what that specific assembly needs.

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

It goes warm side, facing into the heated room of the Westmount property. This is the detail most commonly installed the wrong way round in Westmount, and once the wall is boarded there is no fixing it.

Do you seal the outlet boxes and vents in Westmount?

Yes, individually: every box, vent and pipe penetration in a Westmount wall is sealed separately. Poly run over open boxes looks complete on a Westmount wall but does nothing.

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

Occasionally no: where a Westmount assembly uses spray foam that acts as its own barrier, adding poly can be wrong. The answer turns on the product and its thickness -- confirmed at the Westmount home, not guessed.

Can you do the vapour barrier and the drywall together in Westmount?

Yes, and it is how most Westmount work runs: insulation, vapour barrier and drywall as one job, with one crew accountable for what is behind it. We also cover Central Heights, Cornerstone, Crystal Ridge and the Okotoks area.

Vapour barrier installation in Westmount, sealed before the board goes on

In a Westmount home the vapour barrier is invisible and unforgiving in equal measure -- board over a torn sheet or an open outlet box and it stays that way for the life of the wall. In Westmount 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. Westmount is a Calgary community with a mix of older homes and newer builds, so insulation calls here range from basement development in the newer homes to attic and wall upgrades in the older ones nearby. We cover Westmount, Central Heights, Cornerstone, Crystal Ridge and the Okotoks area, 7 days a week.

What affects the cost of vapour barrier installation in Westmount?

Area, penetrations and detailing

Vapour barrier cost in Westmount 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 Westmount 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. Stipple ceilings turn up throughout Westmount, often with several layers from past repairs.

Where the vapour barrier goes in a Westmount wall, and why it is not a preference

The warm side, always

In Westmount the barrier goes on the warm side of the insulation — the side facing into the heated Westmount room. Its job in a Westmount wall is to stop indoor moisture reaching the cavity and condensing against cold framing.

What goes wrong when it is reversed

On the cold side, a barrier holds moisture inside the assembly instead of excluding it. It is one of the few mistakes in a Westmount wall that cannot be corrected without opening the wall back up, which is exactly why we check every Westmount job before anything is covered.

How we install and seal it in Westmount

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 Westmount home. Poly over open boxes does not make a functioning barrier, and on Westmount jobs started by others it is the number one thing we come across. Stipple ceilings turn up throughout Westmount, often with several layers from past repairs.

Common vapour barrier situations in Westmount

In Westmount, westmount is one of Okotoks’s older, established neighbourhoods, so the work here leans toward popcorn and stipple ceiling removal, settling-crack repair and refinishing tired drywall in original homes that are now well past their first few decades. That is the standard on every job here, big or small — on-site quote, fixed price.

Why Westmount 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 Westmount.

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 Westmount and the Okotoks area, 7 days a week. We quote Westmount jobs on site at no charge and fix the price before starting. Where Westmount still has stipple, we check how many coats are on it before deciding to match or remove.

What to expect from vapour barrier installation in Westmount

Homes in Westmount are settled, so the vapour barrier installation is more often repair and refinish than new board — and the repair has to disappear into a surface that has aged.

Removal is a frequent request in Westmount, and the age of the ceiling decides how the work is approached rather than how it is priced.

Where Westmount still has stipple, we check how many coats are already on it before deciding whether to match it or take it back.
