Does my basement development in Belmont need a vapour barrier?

Almost without exception, yes: exterior basement walls in Belmont require a barrier on the warm side of the insulation ahead of the drywall. Rather than reading it off the plan, we confirm on site in Belmont what that specific assembly needs.

Which side of the insulation does the poly go on in a Belmont home?

It goes warm side, facing into the heated room of the Belmont property. This is the detail most commonly installed the wrong way round in Belmont, and once the wall is boarded there is no fixing it.

Do you seal the outlet boxes and vents in Belmont?

Yes, individually: every box, vent and pipe penetration in a Belmont wall is sealed separately. Poly run over open boxes looks complete on a Belmont wall but does nothing.

Do I still need a vapour barrier in Belmont if I have spray foam?

Occasionally no: where a Belmont assembly uses spray foam that acts as its own barrier, adding poly can be wrong. The answer turns on the product and its thickness -- confirmed at the Belmont home, not guessed.

Can you do the vapour barrier and the drywall together in Belmont?

Yes, and it is how most Belmont work runs: insulation, vapour barrier and drywall as one job, with one crew accountable for what is behind it. We also cover Pine Creek, Alpine Park, Osprey Hill and every Calgary quadrant.

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

In a Belmont home the vapour barrier is invisible and unforgiving in equal measure -- board over a torn sheet or an open outlet box and it stays that way for the life of the wall. In Belmont 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. Belmont is one of SW Calgary's newer communities, where fresh installation and first-year settling work are common, so insulation calls here are usually limited to basement development, since the main floors are already insulated to current code. We cover Belmont, Pine Creek, Alpine Park, Osprey Hill and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Belmont?

Area, penetrations and detailing

Vapour barrier cost in Belmont 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 Belmont 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.

Where the vapour barrier goes in a Belmont wall, and why it is not a preference

The warm side, always

In Belmont the barrier goes on the warm side of the insulation — the side facing into the heated Belmont room. Its job in a Belmont wall is to stop indoor moisture reaching the cavity and condensing against cold framing.

What goes wrong when it is reversed

On the cold side, a barrier holds moisture inside the assembly instead of excluding it. It is one of the few mistakes in a Belmont wall that cannot be corrected without opening the wall back up, which is exactly why we check every Belmont job before anything is covered. In Belmont 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 Belmont

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 Belmont home. Poly over open boxes does not make a functioning barrier, and on Belmont jobs started by others it is the number one thing we come across. Ceilings in Belmont are typically knockdown, and matching that pattern is the part of a repair people notice.

Common vapour barrier situations in Belmont

In Belmont, belmont is a community still building out. Homes there are current-build, so ceilings are typically knockdown and the work is new-build boarding and taping, basement development, and the first-season movement that shows up as a house dries out. Same trusted team, same process on every job — on-site quote, fixed price, no surprises.

Why Belmont 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 Belmont.

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 Belmont and every Calgary quadrant, 7 days a week. We quote Belmont jobs on site at no charge and fix the price before starting.

In Belmont

Belmont: what shapes the job

In a newly built Belmont home the drywall has not yet been through a full winter, so we plan the vapour barrier installation around settling that is still happening rather than settling that has finished.

Basements in Belmont run cooler and damper than the rest of the house, and that affects both the board choice and how long each coat needs.

Knockdown is the standard ceiling texture through Belmont, which means the repair is judged on texture match as much as on whether the surface is flat.
