Does my basement development in Moraine need a vapour barrier?

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

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

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

Do you seal the outlet boxes and vents in Moraine?

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

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

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

Yes. On most Moraine jobs we do insulation, barrier and boarding together, so a single crew answers for what is behind the wall. We also cover Homestead, Twinhills, Lewisburg and every Calgary quadrant.

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

Nothing else in a Moraine 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 Moraine 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. Moraine is one of NE Calgary's newer communities, where fresh installation and first-year settling work are common, so insulation calls here are usually limited to basement development, since the main floors are already insulated to current code. We cover Moraine, Homestead, Twinhills, Lewisburg and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Moraine?

Area, penetrations and detailing

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

The warm side, always

In Moraine the barrier goes on the warm side of the insulation — the side facing into the heated Moraine room. It is what keeps household moisture out of the Moraine 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 Moraine wall that cannot be corrected without opening the wall back up, which is exactly why we check every Moraine job before anything is covered. New homes in Moraine tend to have long unbroken wall runs and high ceilings, which changes how a seam has to be feathered.

How we install and seal it in Moraine

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 Moraine home. A Moraine 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. A lot of our Moraine work starts in the basement, where the ceiling has to stay openable for the plumbing above it.

Common vapour barrier situations in Moraine

In Moraine, moraine is a community still building out. Homes there are current-build, so ceilings are typically knockdown and the work is new-build boarding and taping, basement development, and the first-season movement that shows up as a house dries out. Assessed on site, priced up front, and finished properly — every time.

Why Moraine 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 Moraine.

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

In Moraine

What we tend to find in Moraine

New construction in Moraine means the board is usually sound and square, so vapour barrier installation here is about finishing to a standard the builder did not, rather than undoing someone else's repair.

Knockdown is the standard ceiling texture through Moraine, which means the repair is judged on texture match as much as on whether the surface is flat.

In Moraine we are often the second trade to look at a wall, so the first question is what the original finish actually was.
