Does my basement development in Mount Pleasant need a vapour barrier?

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

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

Do you seal the outlet boxes and vents in Mount Pleasant?

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

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

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

Can you do the vapour barrier and the drywall together in Mount Pleasant?

Yes -- running insulation, barrier and boarding as a single Mount Pleasant 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 Mount Pleasant, sealed before the board goes on

Few parts of a Mount Pleasant build are as completely concealed, or as unforgiving, as the vapour barrier; once boarded, a torn sheet or unsealed box is permanent. In Mount Pleasant 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. Mount Pleasant 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 Mount Pleasant, Glacier Ridge, Medicine Hill, Haskayne and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Mount Pleasant?

Area, penetrations and detailing

Vapour barrier cost in Mount Pleasant 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 Mount Pleasant 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 Mount Pleasant home, and why it is not negotiable

The warm side, always

In Mount Pleasant the barrier goes on the warm side of the insulation — the side facing into the heated Mount Pleasant room. That is how indoor moisture is prevented from moving into a Mount Pleasant 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 Mount Pleasant wall that cannot be corrected without opening the wall back up, which is exactly why we check every Mount Pleasant job before anything is covered. In Mount Pleasant we see everything from original finishes to recent renovations on the same block.

How we install and seal it in Mount Pleasant

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 Mount Pleasant 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 Mount Pleasant jobs. Housing in Mount Pleasant is mixed, which is why we look before we quote rather than after.

Common vapour barrier situations in Mount Pleasant

In Mount Pleasant, we get a steady stream of insurance-related repair calls in Mount Pleasant — 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. We handle all of it the same careful way — on-site quote, fixed price, done right.

Why Mount Pleasant 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 Mount Pleasant.

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 Mount Pleasant and every Calgary quadrant, 7 days a week. On-site quoting in Mount Pleasant costs nothing, and the price is set before anything starts.
