Vapour barrier installation in Reunion, 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 Reunion 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. Reunion is a newer Airdrie community where settling cracks and finishing work are common, so basement development insulation is the main call here, with the main floors already insulated to a recent code. We cover Reunion and all of Airdrie, 7 days a week.

What affects the cost of vapour barrier installation in Reunion?

Area, penetrations and detailing

Vapour barrier cost in Reunion 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 Reunion 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. Removal is a frequent Reunion request, and the age of the ceiling decides how that work is approached.

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

The warm side, always

In Reunion the barrier goes on the warm side of the insulation — the side facing into the heated Reunion 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 Reunion wall that cannot be corrected without opening the wall back up, which is exactly why we check every Reunion job before anything is covered. In Reunion basements the deciding detail is usually access: what has to stay reachable once the ceiling is closed up.

How we install and seal it in Reunion

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 Reunion 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 Reunion

From the first patch to a finished basement, Reunion is one of the areas we serve every week. We take down dated popcorn and stipple ceilings and skim them to a smooth, modern flat finish. We board, tape, mud and finish basements to a smooth, paint-ready Level 4 or 5. One trusted team, fully insured, tidy and dust-conscious in your home. One fixed price after an honest on-site look, and the job done right the first time.

Why Reunion 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 Reunion.

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 Reunion and all of Airdrie, 7 days a week. Free on-site quotes and a fixed price before any work starts. Basement development is common in Reunion, and a basement behaves differently from the rest of the house — cooler, damper, and less forgiving of a rushed finish.

What vapour barrier installation usually involves in Reunion

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

Popcorn ceilings are still in place in parts of Reunion. Anything from that era is treated as unknown until its age is established, and handled accordingly.

Stipple ceilings turn up throughout Reunion, often with more than one layer from earlier repairs, and each layer changes how the new work has to be feathered.

Vapour Barrier Reunion: your questions answered

Does my basement development in Reunion 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 Reunion 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 Reunion?
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 Reunion 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 Reunion?
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 Bayside, Kings Heights, Coopers Crossing and the Airdrie area.
Do you provide free quotes in Reunion?
Yes — we come out to your Reunion home, look at the work and give you a real, fixed on-site price. No guessing after.
