Does my basement development in Renfrew need a vapour barrier?

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

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

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

Do you seal the outlet boxes and vents in Renfrew?

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

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

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

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

Yes, and it is how most Renfrew work runs: insulation, vapour barrier and drywall as one job, with one crew accountable for what is behind it. We also cover Homestead, Moraine, Twinhills and every Calgary quadrant.

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

In a Renfrew 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 Renfrew 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. Renfrew is an older NE 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 Renfrew, Homestead, Moraine, Twinhills and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Renfrew?

Area, penetrations and detailing

Vapour barrier cost in Renfrew 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 Renfrew 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 Renfrew wall, and why it is not a preference

The warm side, always

In Renfrew the barrier goes on the warm side of the insulation — the side facing into the heated Renfrew room. Its job in a Renfrew 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 Renfrew wall that cannot be corrected without opening the wall back up, which is exactly why we check every Renfrew job before anything is covered. Some Renfrew homes are plaster rather than drywall behind the paint, which changes the repair entirely.

How we install and seal it in Renfrew

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 Renfrew home. Poly over open boxes does not make a functioning barrier, and on Renfrew jobs started by others it is the number one thing we come across. Some Renfrew homes are plaster rather than drywall behind the paint, which changes the repair entirely.

Common vapour barrier situations in Renfrew

In Renfrew, we treat every Renfrew job as its own case rather than a standard package — a character home this age can hide anything behind the wall, from original horsehair lath to a 1970s drywall retrofit, and the right repair depends on which one we actually find. Assessed on site, priced up front, and finished properly — every time.

Why Renfrew 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 Renfrew.

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

In Renfrew

What vapour barrier installation usually involves in Renfrew

Housing in Renfrew is mixed enough that two jobs on the same street can need completely different vapour barrier installation work.

In older Renfrew houses it is worth knowing whether there is lath behind the wall before anything is opened up.
