Does my basement development in Rosemont need a vapour barrier?

Almost without exception, yes: exterior basement walls in Rosemont 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 Rosemont what that specific assembly needs.

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

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

Do you seal the outlet boxes and vents in Rosemont?

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

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

Occasionally no: where a Rosemont 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 Rosemont home, not guessed.

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

Yes, and it is how most Rosemont work runs: insulation, vapour barrier and drywall as one job, with one crew accountable for what is behind it. We also cover Glacier Ridge, Medicine Hill, Haskayne and every Calgary quadrant.

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

In a Rosemont 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 Rosemont 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. Rosemont is an older NW 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 Rosemont, Glacier Ridge, Medicine Hill, Haskayne and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Rosemont?

Area, penetrations and detailing

Vapour barrier cost in Rosemont 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 Rosemont 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. Housing in Rosemont is mixed, which is why we look before we quote rather than after.

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

The warm side, always

In Rosemont the barrier goes on the warm side of the insulation — the side facing into the heated Rosemont room. Its job in a Rosemont 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 Rosemont wall that cannot be corrected without opening the wall back up, which is exactly why we check every Rosemont job before anything is covered. Housing in Rosemont is mixed, which is why we look before we quote rather than after.

How we install and seal it in Rosemont

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 Rosemont home. Poly over open boxes does not make a functioning barrier, and on Rosemont jobs started by others it is the number one thing we come across.

Common vapour barrier situations in Rosemont

In Rosemont, rosemont has some of the oldest housing stock we work in, so ceiling and cornice details here can be genuinely unusual — we match what is actually there rather than defaulting to a modern flat finish that would look out of place. Assessed on site, priced up front, and finished properly — every time.

Why Rosemont 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 Rosemont.

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 Rosemont and every Calgary quadrant, 7 days a week. We quote Rosemont jobs on site at no charge and fix the price before starting. Rosemont spans a range of build eras, so what is behind the wall differs street to street.
