Does my basement development in Varsity need a vapour barrier?

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

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

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

Do you seal the outlet boxes and vents in Varsity?

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

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

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

Yes. On most Varsity jobs we do insulation, barrier and boarding together, so a single crew answers for what is behind the wall. We also cover Glacier Ridge, Medicine Hill, Haskayne and every Calgary quadrant.

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

Nothing else in a Varsity 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 Varsity 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. Varsity is an established, sought-after NW Calgary community of 1960s-70s homes and newer infills where plaster, stipple and reno drywall all 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 Varsity, Glacier Ridge, Medicine Hill, Haskayne and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Varsity?

Area, penetrations and detailing

Vapour barrier cost in Varsity 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 Varsity 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. Some Varsity homes are plaster rather than drywall behind the paint, which changes the repair entirely.

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

The warm side, always

In Varsity the barrier goes on the warm side of the insulation — the side facing into the heated Varsity room. It is what keeps household moisture out of the Varsity 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 Varsity wall that cannot be corrected without opening the wall back up, which is exactly why we check every Varsity job before anything is covered. Popcorn ceilings are still in place in parts of Varsity, and anything from that era gets treated carefully until its age is known.

How we install and seal it in Varsity

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 Varsity home. A Varsity 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 Varsity

In Varsity, varsity's 1960s–70s homes mean a lot of popcorn and textured ceiling removal (with the care that era's ceilings deserve), settling cracks, aging drywall and plaster refinishing, and texture-matched patching into original surfaces during renovations. One fixed price after an honest on-site look, and the job done right the first time.

Why Varsity 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 Varsity.

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 Varsity and every Calgary quadrant, 7 days a week. Quotes at your Varsity property are free, with a fixed price before work begins. In older Varsity houses it is worth knowing whether there is lath behind the wall before anything is cut.

In Varsity

What we tend to find in Varsity

Varsity 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.

Removal is a frequent request in Varsity, and the age of the ceiling decides how the work is approached rather than how it is priced.

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