Vapour barrier installation in Glamorgan, sealed before the board goes on

Vapour barrier installation in Glamorgan, 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 Glamorgan 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. Glamorgan is an established SW Calgary community of older homes with plaster, stipple and crack-repair 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 Glamorgan, Pine Creek, Alpine Park, Osprey Hill and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Glamorgan?

Area, penetrations and detailing

Vapour barrier cost in Glamorgan 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 Glamorgan 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 Glamorgan 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 Glamorgan the barrier goes on the warm side of the insulation — the side facing into the heated Glamorgan 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 Glamorgan wall that cannot be corrected without opening the wall back up, which is exactly why we check every Glamorgan job before anything is covered. In older Glamorgan houses it is worth knowing whether there is lath behind the wall before anything is cut.

How we install and seal it in Glamorgan

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 Glamorgan 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 Glamorgan

Glamorgan's vintage housing means we carry a wider kit on every truck here than in a newer community — plaster tools alongside standard drywall gear — since we genuinely do not know which one a given wall will need until we open it up. Assessed on site, priced up front, and finished properly — every time.

Why Glamorgan 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 Glamorgan.

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

Glamorgan: what shapes the job

Homes in Glamorgan have had time to settle without accumulating decades of patch-ups, which is the easiest condition to get an invisible vapour barrier installation result in.

Some Glamorgan homes are plaster rather than drywall behind the paint, which changes the repair entirely — different backing, different bonding, different failure mode.

FAQ — Vapour Barrier Glamorgan

Vapour Barrier Glamorgan: your questions answered

Does my basement development in Glamorgan 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 Glamorgan 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 Glamorgan?
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 Glamorgan 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 Glamorgan?
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.
Is it worth keeping the original plaster in our Glamorgan character home, or should we just replace it with drywall?
Depends on the damage — small areas are usually cheaper and more true-to-character to repair in place; if a whole wall is failing, replacing with drywall and matching the surrounding texture is often the better long-term call. We'll tell you honestly which applies.
