Vapour barrier installation in Edgemont, 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 Edgemont 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. Edgemont is an NW 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 Edgemont, Glacier Ridge, Medicine Hill, Haskayne and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Edgemont?

Area, penetrations and detailing

Vapour barrier cost in Edgemont 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 Edgemont 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.

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

The warm side, always

In Edgemont the barrier goes on the warm side of the insulation — the side facing into the heated Edgemont 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 Edgemont wall that cannot be corrected without opening the wall back up, which is exactly why we check every Edgemont job before anything is covered. Stipple ceilings turn up throughout Edgemont, often with several layers from past repairs.

How we install and seal it in Edgemont

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 Edgemont 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. Popcorn ceilings are still in place in parts of Edgemont, and anything from that era gets treated carefully until its age is known.

Common vapour barrier situations in Edgemont

In Edgemont, edgemont is a community built out through the 1980s and 1990s. Homes from those decades typically carry sprayed ceiling texture — stipple or popcorn — so matching the existing finish is usually what decides whether a repair disappears, and pre-1990 texture is treated as unknown until its age is confirmed. Same trusted team, same process on every job — on-site quote, fixed price, no surprises.

Why Edgemont 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 Edgemont.

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 to expect from vapour barrier installation in Edgemont

In Edgemont we see original finishes and recent renovations on the same block, so the vapour barrier installation is scoped per house, not per postcode.

Where Edgemont still has stipple, we check how many coats are already on it before deciding whether to match it or take it back.

Removal is a frequent request in Edgemont, and the age of the ceiling decides how the work is approached rather than how it is priced.

Vapour Barrier Edgemont: your questions answered

Does my basement development in Edgemont 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 Edgemont 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 Edgemont?
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 Edgemont 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 Edgemont?
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 Glacier Ridge, Medicine Hill, Haskayne and every Calgary quadrant.
