Does my basement development in Willowbrook need a vapour barrier?

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

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

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

Do you seal the outlet boxes and vents in Willowbrook?

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

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

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

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

Yes, and it is how most Willowbrook work runs: insulation, vapour barrier and drywall as one job, with one crew accountable for what is behind it. We also cover Bayside, Kings Heights, Coopers Crossing and the Airdrie area.

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

In a Willowbrook 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 Willowbrook 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. Willowbrook is an Airdrie 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 Willowbrook and all of Airdrie, 7 days a week.

What affects the cost of vapour barrier installation in Willowbrook?

Area, penetrations and detailing

Vapour barrier cost in Willowbrook 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 Willowbrook 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. Basement development is common in Willowbrook, and a basement behaves differently from the rest of the house — cooler, damper, and less forgiving of a rushed finish.

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

The warm side, always

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

How we install and seal it in Willowbrook

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 Willowbrook home. Poly over open boxes does not make a functioning barrier, and on Willowbrook jobs started by others it is the number one thing we come across. Basement development is common in Willowbrook, and a basement behaves differently from the rest of the house — cooler, damper, and less forgiving of a rushed finish.

Common vapour barrier situations in Willowbrook

In Willowbrook, willowbrook is a mature Airdrie community, and our jobs here lean toward repair and basement finishing -- settling cracks that have accumulated over the years, nail pops, and drywall for owners developing an older, unfinished basement. Assessed on site, priced up front, and finished properly — every time.

Why Willowbrook 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 Willowbrook.

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.

Basement development is common in Willowbrook, and a basement behaves differently from the rest of the house — cooler, damper, and less forgiving of a rushed finish.

How Willowbrook homes affect the work

Willowbrook has been through many freeze-thaw cycles, so before quoting vapour barrier installation we look at whether a crack is old movement that has stopped or something still opening.

Basements in Willowbrook run cooler and damper than the rest of the house, and that affects both the board choice and how long each coat needs.
