Vapour barrier installation in Lakeview, 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 Lakeview 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. Lakeview is an established SW Calgary community of 1960s-70s homes with plaster repair and stipple-ceiling work 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 Lakeview, Pine Creek, Alpine Park, Osprey Hill and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Lakeview?

Area, penetrations and detailing

Vapour barrier cost in Lakeview 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 Lakeview 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. Lakeview spans a range of build eras, so what is behind the wall differs street to street.

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

The warm side, always

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

How we install and seal it in Lakeview

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 Lakeview 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. Lakeview spans a range of build eras, so what is behind the wall differs street to street.

Common vapour barrier situations in Lakeview

Lakeview homes at this age often have at least one prior renovation on record, so we check for old patch work before starting a new repair — matching into a previous patch takes a different approach than matching into the original wall. Free on-site quote, one fixed price, and work that holds up after.

Why Lakeview 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 Lakeview.

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 Lakeview

Vapour Barrier Lakeview: your questions answered

Does my basement development in Lakeview 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 Lakeview 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 Lakeview?
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 Lakeview 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 Lakeview?
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.
We're renovating our Lakeview home and found rough drywall behind old cabinets — can you fix that?
Yes — that's a common find in homes this age. We patch and skim it flush with the rest of the wall so it's ready for new cabinetry, tile or paint.
