Vapour barrier installation in South Shore, 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 Shore 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 Shore is a Calgary 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 South Shore and all of Chestermere, 7 days a week.

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

Area, penetrations and detailing

Vapour barrier cost in South Shore 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 Shore 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 South Shore, 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 South Shore the barrier goes on the warm side of the insulation — the side facing into the heated South Shore 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 Shore wall that cannot be corrected without opening the wall back up, which is exactly why we check every South Shore job before anything is covered. A lot of our South Shore work starts in the basement, where the ceiling has to stay openable for the plumbing above it.

How we install and seal it in South Shore

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 Shore 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. A lot of our South Shore work starts in the basement, where the ceiling has to stay openable for the plumbing above it.

Common vapour barrier situations in South Shore

South Shore is one of Chestermere's premium lakeside communities, so our work here leans toward higher-end finishing -- Level 5 skim coats on feature walls, plus basement development in the walkout lots and water-damage repair. Assessed on site, priced up front, and finished properly — every time.

Why South Shore 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 Shore.

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.

Vapour Barrier South Shore: your questions answered

Does my basement development in South Shore 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 Shore 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 Shore?
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 Shore 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 Shore?
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 Kinniburgh, Chestermere Station, Westmere and the Chestermere area.
We want a flawless finish on a feature wall in our South Shore home -- what do you recommend?
For feature walls and vaulted ceilings under strong light we recommend a full Level 5 skim coat -- it's the smoothest finish available and a common choice in South Shore's higher-end homes.
