Does my basement development in Priddis need a vapour barrier?

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

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

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

Do you seal the outlet boxes and vents in Priddis?

Yes. In a Priddis home each outlet, switch box, vent and pipe penetration is sealed on its own. In a Priddis 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 Priddis if I have spray foam?

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

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

Yes. On most Priddis jobs we do insulation, barrier and boarding together, so a single crew answers for what is behind the wall. We also cover Royal Oak, Edgemont, Hawkwood and every Calgary quadrant.

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

Nothing else in a Priddis 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 Priddis 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. Priddis is a Calgary community with a mix of older homes and newer builds, 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 Priddis, 7 days a week.

What affects the cost of vapour barrier installation in Priddis?

Area, penetrations and detailing

Vapour barrier cost in Priddis 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 Priddis 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 Priddis -- and why there is no choice about it

The warm side, always

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

How we install and seal it in Priddis

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 Priddis home. A Priddis 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. Housing in Priddis is mixed, which is why we look before we quote rather than after.

Common vapour barrier situations in Priddis

In Priddis, priddis is a hamlet in Foothills County southwest of Calgary. Country-residential properties tend to be larger than a city build, with bigger open spans and higher ceilings, so access and staging shape the job as much as the technique. Build years vary parcel by parcel out here, so we confirm what is behind the wall on site rather than assuming it from the address. Free on-site quote, one fixed price, and work that holds up after.

Why Priddis 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 Priddis.

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 Priddis, 7 days a week. Quotes at your Priddis property are free, with a fixed price before work begins.
