Vapour barrier installation in Garrison Woods, 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 Garrison Woods 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. Garrison Woods is an inner-SW Calgary community of late-1990s/2000s builds where Level 5 finish and reno drywall are common, so basement development insulation is the main call here, with the main floors already insulated to a recent code. We cover Garrison Woods, Pine Creek, Alpine Park, Osprey Hill and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Garrison Woods?

Area, penetrations and detailing

Vapour barrier cost in Garrison Woods 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 Garrison Woods 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.

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

The warm side, always

In Garrison Woods the barrier goes on the warm side of the insulation — the side facing into the heated Garrison Woods 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 Garrison Woods wall that cannot be corrected without opening the wall back up, which is exactly why we check every Garrison Woods job before anything is covered. In older Garrison Woods houses it is worth knowing whether there is lath behind the wall before anything is cut.

How we install and seal it in Garrison Woods

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 Garrison Woods 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. In older Garrison Woods houses it is worth knowing whether there is lath behind the wall before anything is cut.

Common vapour barrier situations in Garrison Woods

We treat every Garrison Woods job as its own case rather than a standard package — a character home this age can hide anything behind the wall, from original horsehair lath to a 1970s drywall retrofit, and the right repair depends on which one we actually find. Same trusted team, same process on every job — on-site quote, fixed price, no surprises.

We are the ones boarding over it

Left ready to be looked at

Vapour Barrier Garrison Woods: your questions answered

Does my basement development in Garrison Woods 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 Garrison Woods 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 Garrison Woods?
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 Garrison Woods 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 Garrison Woods?
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 Pine Creek, Alpine Park, Osprey Hill and every Calgary quadrant.
Our Garrison Woods home's walls aren't quite straight — will a repair look off?
No — we work with the house's real lines rather than an imaginary plumb wall, so the patch sits flush with what is actually there instead of standing out.
