Does my basement development in West Valley need a vapour barrier?

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

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

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

Do you seal the outlet boxes and vents in West Valley?

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

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

Occasionally no: where a West Valley 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 West Valley home, not guessed.

Can you do the vapour barrier and the drywall together in West Valley?

Yes, and it is how most West Valley work runs: insulation, vapour barrier and drywall as one job, with one crew accountable for what is behind it. We also cover Cochrane, Sunset Ridge, Heritage Hills and the Cochrane area.

Vapour barrier installation in West Valley, sealed before the board goes on

In a West Valley 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 West Valley 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. West Valley is an established Cochrane community where reno and repair drywall are typical, so basement development and the occasional upgrade where older insulation has settled or thinned are common here. We cover West Valley and all of Cochrane, 7 days a week.

What affects the cost of vapour barrier installation in West Valley?

Area, penetrations and detailing

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

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

The warm side, always

In West Valley the barrier goes on the warm side of the insulation — the side facing into the heated West Valley room. Its job in a West Valley 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 West Valley wall that cannot be corrected without opening the wall back up, which is exactly why we check every West Valley job before anything is covered. Housing in West Valley is mixed, which is why we look before we quote rather than after.

How we install and seal it in West Valley

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

Common vapour barrier situations in West Valley

In West Valley, west Valley is a residential neighbourhood in Cochrane. Build years vary across the neighbourhood, so rather than assume what is behind the wall we confirm it on site — the finish, the texture and how the existing surface has aged all change how the repair is approached. One fixed price after an honest on-site look, and the job done right the first time.

Why West Valley 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 West Valley.

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 West Valley and all of Cochrane, 7 days a week. We quote West Valley jobs on site at no charge and fix the price before starting. Housing in West Valley is mixed, which is why we look before we quote rather than after.
