Does my basement development in Sherwood need a vapour barrier?

Almost without exception, yes: exterior basement walls in Sherwood require a barrier on the warm side of the insulation ahead of the drywall. Rather than reading it off the plan, we confirm on site in Sherwood what that specific assembly needs.

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

It goes warm side, facing into the heated room of the Sherwood property. This is the detail most commonly installed the wrong way round in Sherwood, and once the wall is boarded there is no fixing it.

Do you seal the outlet boxes and vents in Sherwood?

Yes, individually: every box, vent and pipe penetration in a Sherwood wall is sealed separately. Poly run over open boxes looks complete on a Sherwood wall but does nothing.

Do I still need a vapour barrier in Sherwood if I have spray foam?

Occasionally no: where a Sherwood assembly uses spray foam that acts as its own barrier, adding poly can be wrong. The answer turns on the product and its thickness -- confirmed at the Sherwood home, not guessed.

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

Yes, and it is how most Sherwood work runs: insulation, vapour barrier and drywall as one job, with one crew accountable for what is behind it. We also cover Glacier Ridge, Medicine Hill, Haskayne and every Calgary quadrant.

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

In a Sherwood home the vapour barrier is invisible and unforgiving in equal measure -- board over a torn sheet or an open outlet box and it stays that way for the life of the wall. In Sherwood 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. Sherwood is one of NW 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 Sherwood, Glacier Ridge, Medicine Hill, Haskayne and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Sherwood?

Area, penetrations and detailing

Vapour barrier cost in Sherwood 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 Sherwood 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. A lot of our Sherwood work starts in the basement, where the ceiling has to stay openable for the plumbing above it.

Where the vapour barrier goes in a Sherwood wall, and why it is not a preference

The warm side, always

In Sherwood the barrier goes on the warm side of the insulation — the side facing into the heated Sherwood room. Its job in a Sherwood wall is to stop indoor moisture reaching the cavity and condensing against cold framing.

What goes wrong when it is reversed

On the cold side, a barrier holds moisture inside the assembly instead of excluding it. It is one of the few mistakes in a Sherwood wall that cannot be corrected without opening the wall back up, which is exactly why we check every Sherwood job before anything is covered. Ceilings in Sherwood are typically knockdown, and matching that pattern is the part of a repair people notice.

How we install and seal it in Sherwood

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 Sherwood home. Poly over open boxes does not make a functioning barrier, and on Sherwood jobs started by others it is the number one thing we come across. Because Sherwood is largely new construction, the board is still settling and hairline cracking at corners is the normal first-year complaint.

Common vapour barrier situations in Sherwood

In Sherwood, sherwood is a community built out in the 2010s. 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. We handle all of it the same careful way — on-site quote, fixed price, done right.

Why Sherwood 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 Sherwood.

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 Sherwood and every Calgary quadrant, 7 days a week. We quote Sherwood jobs on site at no charge and fix the price before starting. Knockdown is the standard ceiling texture through Sherwood, so a patch gets tested for match before the whole ceiling is sprayed.

How Sherwood homes affect the work

Sherwood is recent enough that we are normally working with original, untouched surfaces — which makes matching straightforward and keeps the vapour barrier installation quicker than it would be in an older area.

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

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