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

In a Shaganappi 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 Shaganappi 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. Shaganappi is an older SW 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 Shaganappi, Pine Creek, Alpine Park, Osprey Hill and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Shaganappi?

Area, penetrations and detailing

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

The warm side, always

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

How we install and seal it in Shaganappi

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 Shaganappi home. Poly over open boxes does not make a functioning barrier, and on Shaganappi jobs started by others it is the number one thing we come across. In older Shaganappi houses it is worth knowing whether there is lath behind the wall before anything is cut.

Common vapour barrier situations in Shaganappi

In Shaganappi, a lot of our Shaganappi calls come from owners partway through a renovation who have opened up a wall and found old plaster, horsehair lath, or a mix of both — we can patch back into it or remove and replace with modern board, whichever suits the rest of the room. One fixed price after an honest on-site look, and the job done right the first time.

Why Shaganappi 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 Shaganappi.

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

Shaganappi: what shapes the job

Shaganappi spans a range of build eras, so what is behind the wall genuinely differs street to street — which is why we look before quoting the vapour barrier installation rather than after.

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

Vapour Barrier Shaganappi: your questions answered

Does my basement development in Shaganappi need a vapour barrier?
Almost without exception, yes: exterior basement walls in Shaganappi 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 Shaganappi what that specific assembly needs.
Which side of the insulation does the poly go on in a Shaganappi home?
It goes warm side, facing into the heated room of the Shaganappi property. This is the detail most commonly installed the wrong way round in Shaganappi, and once the wall is boarded there is no fixing it.
Do you seal the outlet boxes and vents in Shaganappi?
Yes, individually: every box, vent and pipe penetration in a Shaganappi wall is sealed separately. Poly run over open boxes looks complete on a Shaganappi wall but does nothing.
Do I still need a vapour barrier in Shaganappi if I have spray foam?
Occasionally no: where a Shaganappi 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 Shaganappi home, not guessed.
Can you do the vapour barrier and the drywall together in Shaganappi?
Yes, and it is how most Shaganappi 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.
