Does my basement development in Sundance need a vapour barrier?

Almost without exception, yes: exterior basement walls in Sundance 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 Sundance what that specific assembly needs.

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

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

Do you seal the outlet boxes and vents in Sundance?

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

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

Occasionally no: where a Sundance 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 Sundance home, not guessed.

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

Yes, and it is how most Sundance work runs: insulation, vapour barrier and drywall as one job, with one crew accountable for what is behind it. We also cover Rangeview, Ricardo Ranch, Belvedere and every Calgary quadrant.

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

In a Sundance 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 Sundance 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. Sundance is an established SE lake community where reno and ceiling drywall are typical, so basement development and the occasional upgrade where older insulation has settled or thinned are common here. We cover Sundance, Rangeview, Ricardo Ranch, Belvedere and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Sundance?

Area, penetrations and detailing

Vapour barrier cost in Sundance 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 Sundance 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 Sundance work starts in the basement, where the ceiling has to stay openable for the plumbing above it.

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

The warm side, always

In Sundance the barrier goes on the warm side of the insulation — the side facing into the heated Sundance room. Its job in a Sundance 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 Sundance wall that cannot be corrected without opening the wall back up, which is exactly why we check every Sundance job before anything is covered. A lot of our Sundance work starts in the basement, where the ceiling has to stay openable for the plumbing above it.

How we install and seal it in Sundance

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 Sundance home. Poly over open boxes does not make a functioning barrier, and on Sundance jobs started by others it is the number one thing we come across. A lot of our Sundance work starts in the basement, where the ceiling has to stay openable for the plumbing above it.

Common vapour barrier situations in Sundance

In Sundance, basement development is common in Sundance at this point in a home's life — owners are finishing rec rooms and bedrooms below grade decades after the original build, so we do a lot of new boarding, taping and Level 4/5 finishing down there. One fixed price after an honest on-site look, and the job done right the first time.

Why Sundance 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 Sundance.

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.

We cover Sundance and every Calgary quadrant, 7 days a week. We quote Sundance jobs on site at no charge and fix the price before starting. A lot of our Sundance work starts in the basement, where the ceiling has to stay openable for the plumbing above it.

In Sundance

What vapour barrier installation usually involves in Sundance

Housing in Sundance is mixed enough that two jobs on the same street can need completely different vapour barrier installation work.

Basements in Sundance run cooler and damper than the rest of the house, and that affects both the board choice and how long each coat needs.
