Vapour barrier installation in Crescent Heights, 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 Crescent Heights 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. Crescent Heights is an older NE 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 Crescent Heights, Homestead, Moraine, Twinhills and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Crescent Heights?

Area, penetrations and detailing

Vapour barrier cost in Crescent Heights 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 Crescent Heights 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 Crescent Heights 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 Crescent Heights the barrier goes on the warm side of the insulation — the side facing into the heated Crescent Heights 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 Crescent Heights wall that cannot be corrected without opening the wall back up, which is exactly why we check every Crescent Heights job before anything is covered. Infill construction in Crescent Heights means new-build finishing and old-house repair often run on the same block.

How we install and seal it in Crescent Heights

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 Crescent Heights 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 Crescent Heights

Crescent Heights is one of the area's older, character neighbourhoods, so the work here runs to genuine plaster repair, taking down dated textured ceilings, and patching into original lath-and-plaster surfaces so a repair disappears. Where owners are renovating or building infills, we also handle full new-construction boarding and finishing. We handle all of it the same careful way — on-site quote, fixed price, done right.

Why Crescent Heights 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 Crescent Heights.

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

Crescent Heights: what shapes the job

Housing in Crescent Heights is mixed enough that two jobs on the same street can need completely different vapour barrier installation work.

Infill construction in Crescent Heights means new-build finishing and old-house repair often run on the same street.

In older Crescent Heights houses it is worth knowing whether there is lath behind the wall before anything is opened up.

FAQ — Vapour Barrier Crescent Heights

Vapour Barrier Crescent Heights: your questions answered

Does my basement development in Crescent Heights 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 Crescent Heights 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 Crescent Heights?
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 Crescent Heights 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 Crescent Heights?
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.
Our Crescent Heights 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.
