Does my basement development in Lewisburg need a vapour barrier?

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

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

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

Do you seal the outlet boxes and vents in Lewisburg?

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

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

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

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

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

Nothing else in a Lewisburg 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 Lewisburg 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. Lewisburg 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 Lewisburg, Homestead, Moraine, Twinhills and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Lewisburg?

Area, penetrations and detailing

Vapour barrier cost in Lewisburg 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 Lewisburg 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. Because Lewisburg is largely new construction, the board is still settling and hairline cracking at corners is the normal first-year complaint.

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

The warm side, always

In Lewisburg the barrier goes on the warm side of the insulation — the side facing into the heated Lewisburg room. It is what keeps household moisture out of the Lewisburg 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 Lewisburg wall that cannot be corrected without opening the wall back up, which is exactly why we check every Lewisburg job before anything is covered. Basement development is common in Lewisburg, and a basement behaves differently from the rest of the house — cooler, damper, and less forgiving of a rushed finish.

How we install and seal it in Lewisburg

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 Lewisburg home. A Lewisburg 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. Knockdown is the standard ceiling texture through Lewisburg, so a patch gets tested for match before the whole ceiling is sprayed.

Common vapour barrier situations in Lewisburg

In Lewisburg, lewisburg 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. Free on-site quote, one fixed price, and work that holds up after.

Why Lewisburg 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 Lewisburg.

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 Lewisburg and every Calgary quadrant, 7 days a week. Quotes at your Lewisburg property are free, with a fixed price before work begins. In Lewisburg basements the deciding detail is usually access: what has to stay reachable once the ceiling is closed up.

In Lewisburg

What vapour barrier installation usually involves in Lewisburg

In a newly built Lewisburg home the drywall has not yet been through a full winter, so we plan the vapour barrier installation around settling that is still happening rather than settling that has finished.

Builder deficiency work is common in Lewisburg — nail pops, corner cracks and seams that only appeared after possession.

Ceilings here are typically knockdown, and matching that spray pattern is the part people notice if it is done badly — so we test the match before committing to the whole ceiling.
