Vapour barrier installation in The Cove, 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 The Cove 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. The Cove 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 The Cove and all of Chestermere, 7 days a week.

What affects the cost of vapour barrier installation in The Cove?

Area, penetrations and detailing

Vapour barrier cost in The Cove 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 The Cove 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. A lot of our The Cove work starts in the basement, where the ceiling has to stay openable for the plumbing above it.

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

The warm side, always

In The Cove the barrier goes on the warm side of the insulation — the side facing into the heated The Cove 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 The Cove wall that cannot be corrected without opening the wall back up, which is exactly why we check every The Cove job before anything is covered. Basement development is common in The Cove, and a basement behaves differently from the rest of the house — cooler, damper, and less forgiving of a rushed finish.

How we install and seal it in The Cove

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 The Cove 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 The Cove

The Cove is an established lakeside community, so the drywall calls we get here are mostly repair-focused -- settling cracks, nail pops, holes from furniture -- along with basement drywall for owners updating a lower level. Assessed on site, priced up front, and finished properly — every time.

Why The Cove 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 The Cove.

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.

What we tend to find in The Cove

The Cove 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.

A lot of the work in The Cove starts in the basement, where the ceiling has to stay openable for the plumbing and ducting above it.

Vapour Barrier The Cove: your questions answered

Does my basement development in The Cove 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 The Cove 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 The Cove?
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 The Cove 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 The Cove?
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.
Can you repair and paint in one visit in The Cove?
Often yes -- we patch, texture-match, prime and paint in one booking in The Cove so the wall looks completely finished when we leave.
