Does my basement development in Thorncliffe need a vapour barrier?

Yes, essentially always -- our climate means a Thorncliffe exterior basement wall gets a barrier on the warm side of the insulation before drywall goes on. The requirement for your Thorncliffe 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 Thorncliffe home?

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

Do you seal the outlet boxes and vents in Thorncliffe?

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

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

Sometimes it should not go on at all -- some spray foam assemblies in Thorncliffe 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 Thorncliffe instead of assuming.

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

Yes -- running insulation, barrier and boarding as a single Thorncliffe job is our usual approach, and it puts one crew on the hook for what ends up in the wall. We also cover Glacier Ridge, Medicine Hill, Haskayne and every Calgary quadrant.

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

Few parts of a Thorncliffe build are as completely concealed, or as unforgiving, as the vapour barrier; once boarded, a torn sheet or unsealed box is permanent. In Thorncliffe 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. Thorncliffe is an older NW Calgary community where settling cracks, aging texture and the occasional plaster repair come up, so attic top-ups and wall insulation upgrades are common here alongside basement development, since original insulation levels are often below current standards. We cover Thorncliffe, Glacier Ridge, Medicine Hill, Haskayne and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Thorncliffe?

Area, penetrations and detailing

Vapour barrier cost in Thorncliffe 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 Thorncliffe 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. Thorncliffe spans a range of build eras, so what is behind the wall differs street to street.

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

The warm side, always

In Thorncliffe the barrier goes on the warm side of the insulation — the side facing into the heated Thorncliffe room. That is how indoor moisture is prevented from moving into a Thorncliffe 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 Thorncliffe wall that cannot be corrected without opening the wall back up, which is exactly why we check every Thorncliffe job before anything is covered.

How we install and seal it in Thorncliffe

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 Thorncliffe 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 Thorncliffe jobs. Thorncliffe spans a range of build eras, so what is behind the wall differs street to street.

Common vapour barrier situations in Thorncliffe

In Thorncliffe, we get a steady stream of insurance-related repair calls in Thorncliffe — older plumbing and roofing mean occasional water damage, and we document and repair it properly, with photos for the claim, rather than just closing it up. One fixed price after an honest on-site look, and the job done right the first time.

Why Thorncliffe 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 Thorncliffe.

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 Thorncliffe and every Calgary quadrant, 7 days a week. On-site quoting in Thorncliffe costs nothing, and the price is set before anything starts. Thorncliffe spans a range of build eras, so what is behind the wall differs street to street.
