Does my basement development in Sunnyside need a vapour barrier?

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

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

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

Do you seal the outlet boxes and vents in Sunnyside?

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

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

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

Yes. On most Sunnyside 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 Sunnyside, sealed before the board goes on

Nothing else in a Sunnyside 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 Sunnyside 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. Sunnyside is an older NW 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 Sunnyside, Glacier Ridge, Medicine Hill, Haskayne and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Sunnyside?

Area, penetrations and detailing

Vapour barrier cost in Sunnyside 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 Sunnyside 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. Housing in Sunnyside is mixed, which is why we look before we quote rather than after.

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

The warm side, always

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

How we install and seal it in Sunnyside

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 Sunnyside home. A Sunnyside 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 Sunnyside is mixed, which is why we look before we quote rather than after.

Common vapour barrier situations in Sunnyside

In Sunnyside, sunnyside has some of the oldest housing stock we work in, so ceiling and cornice details here can be genuinely unusual — we match what is actually there rather than defaulting to a modern flat finish that would look out of place. Free on-site quote, one fixed price, and work that holds up after.

Why Sunnyside 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 Sunnyside.

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 Sunnyside and every Calgary quadrant, 7 days a week. Quotes at your Sunnyside property are free, with a fixed price before work begins. Sunnyside spans a range of build eras, so what is behind the wall differs street to street.
