Does my basement development in Millrise need a vapour barrier?

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

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

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

Do you seal the outlet boxes and vents in Millrise?

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

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

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

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

Yes, and it is how most Millrise work runs: insulation, vapour barrier and drywall as one job, with one crew accountable for what is behind it. We also cover Pine Creek, Alpine Park, Osprey Hill and every Calgary quadrant.

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

In a Millrise 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 Millrise 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. Millrise is a mature SW Calgary 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 Millrise, Pine Creek, Alpine Park, Osprey Hill and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Millrise?

Area, penetrations and detailing

Vapour barrier cost in Millrise 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 Millrise 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. Where Millrise still has stipple, we check how many coats are on it before deciding to match or remove.

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

The warm side, always

In Millrise the barrier goes on the warm side of the insulation — the side facing into the heated Millrise room. Its job in a Millrise 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 Millrise wall that cannot be corrected without opening the wall back up, which is exactly why we check every Millrise job before anything is covered. Where Millrise still has stipple, we check how many coats are on it before deciding to match or remove.

How we install and seal it in Millrise

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 Millrise home. Poly over open boxes does not make a functioning barrier, and on Millrise jobs started by others it is the number one thing we come across.

Common vapour barrier situations in Millrise

In Millrise, millrise's 1990s-era stipple ceilings are a frequent removal request, and because these homes are old enough now for real seasonal movement, we routinely pair that with settling-crack and nail-pop repair in the same rooms. Free on-site quote, one fixed price, and work that holds up after.

Why Millrise 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 Millrise.

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 Millrise and every Calgary quadrant, 7 days a week. We quote Millrise jobs on site at no charge and fix the price before starting. Stipple ceilings turn up throughout Millrise, often with several layers from past repairs.

Millrise spans a range of build eras, so what is behind the wall genuinely differs street to street — which is why we look before quoting the vapour barrier installation rather than after.
