Does my basement development in NE Calgary need a vapour barrier?

Yes, essentially always -- our climate means a NE exterior basement wall gets a barrier on the warm side of the insulation before drywall goes on. The requirement for your NE assembly is confirmed in person on the visit, not guessed from the plan.

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

The warm side of the assembly -- the one looking into the heated NE room. More than anything else on a NE job this gets reversed, and it cannot be corrected after boarding.

Do you seal the outlet boxes and vents in NE Calgary?

Yes -- each and every outlet, switch box, vent and pipe going through a NE wall is sealed on its own. Hanging poly over open boxes in NE framing gives you the look of a finished barrier without the performance.

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

Sometimes it should not go on at all -- some spray foam assemblies in NE homes are already the barrier, and poly over them is the wrong move. It varies with product and thickness, so we verify it on site in NE instead of assuming.

Can you do the vapour barrier and the drywall together in NE Calgary?

Yes -- running insulation, barrier and boarding as a single NE job is our usual approach, and it puts one crew on the hook for what ends up in the wall. We also cover Redstone, Coventry Hills, Whitehorn and every Calgary quadrant.

Vapour barrier installation in NE Calgary, sealed before the board goes on

Few parts of a NE build are as completely concealed, or as unforgiving, as the vapour barrier; once boarded, a torn sheet or unsealed box is permanent. In NE Calgary 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. NE Calgary is spanning established communities like Whitehorn and Rundle and newer ones like Skyview, Redstone and Cornerstone, so insulation calls here range from basement development in the newer homes to attic and wall upgrades in the older ones nearby. We cover all of NE Calgary, 7 days a week.

What affects the cost of vapour barrier installation in NE Calgary?

Area, penetrations and detailing

Vapour barrier cost in NE Calgary 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 NE Calgary 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.

Vapour barrier placement in a NE home, and why it is not negotiable

The warm side, always

In NE Calgary the barrier goes on the warm side of the insulation — the side facing into the heated NE Calgary room. That is how indoor moisture is prevented from moving into a NE cavity and condensing on cold framing.

What goes wrong when it is reversed

Installed cold-side, the barrier traps moisture within the assembly rather than keeping it out. It is one of the few mistakes in a NE Calgary wall that cannot be corrected without opening the wall back up, which is exactly why we check every NE Calgary job before anything is covered.

How we install and seal it in NE Calgary

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 NE Calgary home. Where poly is on the walls but the boxes behind are open, the barrier does not work; it is the commonest fault we find on part-finished NE jobs.

Common vapour barrier situations in NE Calgary

New basement developments

insulation calls here range from basement development in the newer homes to attic and wall upgrades in the older ones nearby, and that makes basement work the main source of NE vapour barrier jobs -- exterior walls and rim joist finished before the drywall stage. See our basement drywall work if the boarding is part of the same job.

Renovations and open walls

When a wall in a NE Calgary home is already open, it is the only practical moment to add or repair a barrier.

Repairing a damaged barrier

We also repair poly that has been torn by other trades after it went up — a common find once electrical and plumbing have been through.

Why NE Calgary 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 NE Calgary.

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 all of NE Calgary, 7 days a week. On-site quoting in NE costs nothing, and the price is set before anything starts.

How it works

Simple, clean, on schedule — Vapour Barrier Installation in NE Calgary

Free quote

Someone attends the NE Calgary address, inspects what the vapour barrier installation actually involves, and gives you a firm number before leaving. Nothing is estimated from a photo.

Book a day

We book around you, not around our week. When the day comes the NE Calgary crew is there at the agreed time, loaded for the vapour barrier installation.

The work

Floors get covered and doorways sealed before the vapour barrier installation begins. Your NE Calgary home stays liveable while we work, and the site is tidied each day.

Walk it with you

The vapour barrier installation is not done when the tools are packed — it is done when you have walked it in NE Calgary and told us it is right.
