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

Nothing else in a Dover 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 Dover 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. Dover is an older SE 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 Dover, Rangeview, Ricardo Ranch, Belvedere and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Dover?

Area, penetrations and detailing

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

The warm side, always

In Dover the barrier goes on the warm side of the insulation — the side facing into the heated Dover room. It is what keeps household moisture out of the Dover 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 Dover wall that cannot be corrected without opening the wall back up, which is exactly why we check every Dover job before anything is covered. Dover spans a range of build eras, so what is behind the wall differs street to street.

How we install and seal it in Dover

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 Dover home. A Dover 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. In Dover we see everything from original finishes to recent renovations on the same block.

Common vapour barrier situations in Dover

In Dover, we see plenty of settling-related drywall cracks in Dover that trace back to the original foundation curing decades ago — cosmetic at this point, and a straightforward repair once we've confirmed there's no ongoing movement. That is the standard on every job here, big or small — on-site quote, fixed price.

Why Dover 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 Dover.

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 Dover and every Calgary quadrant, 7 days a week. Quotes at your Dover property are free, with a fixed price before work begins.

Vapour Barrier Dover: your questions answered

Does my basement development in Dover need a vapour barrier?
Yes in nearly every case. In this climate a Dover basement exterior wall needs a barrier on the warm side of the insulation before boarding. What your particular Dover assembly requires is established at the visit, not inferred from a drawing.
Which side of the insulation does the poly go on in a Dover home?
On the warm side, meaning the face turned toward the heated space in your Dover home. Of all the details on a Dover job this is the one most often got backwards, and boarding makes it permanent.
Do you seal the outlet boxes and vents in Dover?
Yes. In a Dover home each outlet, switch box, vent and pipe penetration is sealed on its own. In a Dover 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 Dover if I have spray foam?
Not always. Certain spray foam assemblies are their own barrier, and putting poly over one in a Dover home can be a mistake. Product and thickness decide it, which is why we check at the Dover property rather than assume.
Can you do the vapour barrier and the drywall together in Dover?
Yes. On most Dover jobs we do insulation, barrier and boarding together, so a single crew answers for what is behind the wall. We also cover Rangeview, Ricardo Ranch, Belvedere and every Calgary quadrant.
