Vapour barrier installation in Whitehorn, 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 Whitehorn 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. Whitehorn is an established NE Calgary community of older homes where repair and stipple-ceiling work are common, so attic top-ups and wall insulation upgrades are common here alongside basement development, since original insulation levels are often below current standards. We cover Whitehorn, Homestead, Moraine, Twinhills and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Whitehorn?

Area, penetrations and detailing

Vapour barrier cost in Whitehorn 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 Whitehorn 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. Housing in Whitehorn is mixed, which is why we look before we quote rather than after.

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

The warm side, always

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

How we install and seal it in Whitehorn

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 Whitehorn 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.

Common vapour barrier situations in Whitehorn

A lot of our repeat work in Whitehorn comes from owners who had a patch done elsewhere that never quite matched — we re-texture it properly, blending into the original surface rather than leaving a second visible seam. Assessed on site, priced up front, and finished properly — every time.

Why Whitehorn 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 Whitehorn.

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.

FAQ — Vapour Barrier Whitehorn

Vapour Barrier Whitehorn: your questions answered

Does my basement development in Whitehorn 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 Whitehorn 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 Whitehorn?
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 Whitehorn 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 Whitehorn?
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 Homestead, Moraine, Twinhills and every Calgary quadrant.
Do older Whitehorn homes need a different repair approach than newer builds?
Somewhat — established homes have had more time to settle and more layers of past work, so we always assess what's actually on the wall (original texture vs. a past patch) before matching it, rather than assuming one standard finish.
