Does my basement development in Westmere need a vapour barrier?

Almost without exception, yes: exterior basement walls in Westmere 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 Westmere what that specific assembly needs.

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

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

Do you seal the outlet boxes and vents in Westmere?

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

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

Occasionally no: where a Westmere 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 Westmere home, not guessed.

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

Yes, and it is how most Westmere work runs: insulation, vapour barrier and drywall as one job, with one crew accountable for what is behind it. We also cover Kinniburgh, Chestermere Station, Rainbow Falls and the Chestermere area.

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

In a Westmere 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 Westmere 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. Westmere is a growing Chestermere lake-community where fresh installation and first-year settling work are common, so basement development insulation is the main call here, with the main floors already insulated to a recent code. We cover Westmere and all of Chestermere, 7 days a week.

What affects the cost of vapour barrier installation in Westmere?

Area, penetrations and detailing

Vapour barrier cost in Westmere 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 Westmere 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 the vapour barrier goes in a Westmere wall, and why it is not a preference

The warm side, always

In Westmere the barrier goes on the warm side of the insulation — the side facing into the heated Westmere room. Its job in a Westmere 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 Westmere wall that cannot be corrected without opening the wall back up, which is exactly why we check every Westmere job before anything is covered. Westmere spans a range of build eras, so what is behind the wall differs street to street.

How we install and seal it in Westmere

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 Westmere home. Poly over open boxes does not make a functioning barrier, and on Westmere jobs started by others it is the number one thing we come across. Westmere spans a range of build eras, so what is behind the wall differs street to street.

Why Westmere 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 Westmere.

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 Westmere and all of Chestermere, 7 days a week. We quote Westmere jobs on site at no charge and fix the price before starting.
