Does my basement development in SW Calgary need a vapour barrier?

Yes in nearly every case. In this climate a SW basement exterior wall needs a barrier on the warm side of the insulation before boarding. What your particular SW assembly requires is established at the visit, not inferred from a drawing.

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

On the warm side, meaning the face turned toward the heated space in your SW home. Of all the details on a SW job this is the one most often got backwards, and boarding makes it permanent.

Do you seal the outlet boxes and vents in SW Calgary?

Yes. In a SW home each outlet, switch box, vent and pipe penetration is sealed on its own. In a SW home, poly draped over open boxes has the appearance of a finished job and none of the function.

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

Not always. Certain spray foam assemblies are their own barrier, and putting poly over one in a SW home can be a mistake. Product and thickness decide it, which is why we check at the SW property rather than assume.

Can you do the vapour barrier and the drywall together in SW Calgary?

Yes. On most SW jobs we do insulation, barrier and boarding together, so a single crew answers for what is behind the wall. We also cover Aspen Woods, Signal Hill, Lakeview and every Calgary quadrant.

Vapour barrier installation in SW Calgary, sealed before the board goes on

Nothing else in a SW build is this hidden and this unforgiving: after the drywall goes up, a tear in the sheet or an unsealed box is there permanently. In SW Calgary 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. SW Calgary is covering high-spend areas like Aspen Woods and Springbank Hill alongside established suburbs like Lakeview and Glamorgan, so insulation calls here range from basement development in the newer homes to attic and wall upgrades in the older ones nearby. We cover all of SW Calgary, 7 days a week.

What affects the cost of vapour barrier installation in SW Calgary?

Area, penetrations and detailing

Vapour barrier cost in SW Calgary 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 SW Calgary 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.

The side a vapour barrier belongs on in SW -- and why there is no choice about it

The warm side, always

In SW Calgary the barrier goes on the warm side of the insulation — the side facing into the heated SW Calgary room. It is what keeps household moisture out of the SW wall cavity, where it would condense on cold framing.

What goes wrong when it is reversed

Put the barrier on the cold side and it seals moisture into the assembly rather than out of it. It is one of the few mistakes in a SW Calgary wall that cannot be corrected without opening the wall back up, which is exactly why we check every SW Calgary job before anything is covered.

How we install and seal it in SW Calgary

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 SW Calgary home. A SW wall with poly up and boxes still open behind it has no working vapour barrier -- and it is the most frequent thing we find on jobs someone else began.

Common vapour barrier situations in SW Calgary

New basement developments

insulation calls here range from basement development in the newer homes to attic and wall upgrades in the older ones nearby, which is why most SW vapour barrier work arrives with a basement build -- exterior walls and rim joist detailed ahead of drywall. See our basement drywall work if the boarding is part of the same job.

Renovations and open walls

When a wall in a SW Calgary home is already open, it is the only practical moment to add or repair a barrier.

Repairing a damaged barrier

We also repair poly that has been torn by other trades after it went up — a common find once electrical and plumbing have been through.

Why SW Calgary 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 SW Calgary.

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 all of SW Calgary, 7 days a week. Quotes at your SW property are free, with a fixed price before work begins.
