Vapour barrier installation in Willowbrook, 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 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.

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

The warm side, always

In Willowbrook the barrier goes on the warm side of the insulation — the side facing into the heated Willowbrook 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 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 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. 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

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.

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.

Vapour Barrier Willowbrook: your questions answered

Does my basement development in Willowbrook 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 Willowbrook 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 Willowbrook?
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 Willowbrook 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 Willowbrook?
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 Bayside, Kings Heights, Coopers Crossing and the Airdrie area.
Our Willowbrook basement has never been finished -- what's involved in drywalling it?
We handle the full scope -- boarding around your framing and mechanicals, taping and mudding to Level 4 or 5, and coordinating timing with your electrical and insulation trades so your Willowbrook basement is ready for paint on schedule.
