Vapour barrier installation in South Calgary, sealed before the board goes on

Vapour barrier installation in South Calgary, 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 South Calgary 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. South Calgary is an older SW Calgary community where settling cracks, aging texture and the occasional plaster repair come up, 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 South Calgary, Pine Creek, Alpine Park, Osprey Hill and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in South Calgary?

Area, penetrations and detailing

Vapour barrier cost in South Calgary 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 South Calgary 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. In older South Calgary houses it is worth knowing whether there is lath behind the wall before anything is cut.

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

The warm side, always

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

How we install and seal it in South Calgary

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 South Calgary 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 South Calgary houses it is worth knowing whether there is lath behind the wall before anything is cut.

Common vapour barrier situations in South Calgary

South Calgary's older housing stock means ceiling heights, corner details and wall textures vary house to house even on the same street, so every plaster or drywall repair here starts with matching what is already on that specific wall, not a standard template. Free on-site quote, one fixed price, and work that holds up after.

Why South Calgary 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 South Calgary.

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 South Calgary and every Calgary quadrant, 7 days a week. Free on-site quotes and a fixed price before any work starts. Some South Calgary homes are plaster rather than drywall behind the paint, which changes the repair entirely.

FAQ — Vapour Barrier South Calgary

Vapour Barrier South Calgary: your questions answered

Does my basement development in South Calgary 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 South Calgary 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 South Calgary?
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 South Calgary 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 South Calgary?
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 South Calgary 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.
