Vapour barrier installation in West Springs, sealed before the board goes on

A vapour barrier is one of the few things in a build that is completely hidden and completely unforgiving — once the drywall is on, a torn sheet or an unsealed outlet box stays that way for the life of the wall. In West Springs 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. West Springs is one of SW Calgary's newer communities, where fresh installation and first-year settling work are common, so insulation calls here are usually limited to basement development, since the main floors are already insulated to current code. We cover West Springs, Pine Creek, Alpine Park, Osprey Hill and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in West Springs?

Area, penetrations and detailing

Vapour barrier cost in West Springs 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 West Springs 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.

Which side the vapour barrier goes on, and why that is not optional

The warm side, always

In West Springs the barrier goes on the warm side of the insulation — the side facing into the heated West Springs room. That is what stops indoor moisture from travelling into the wall cavity and condensing when it reaches cold framing.

What goes wrong when it is reversed

A barrier installed on the cold side traps moisture inside the assembly instead of keeping it out. It is one of the few mistakes in a West Springs wall that cannot be corrected without opening the wall back up, which is exactly why we check every West Springs job before anything is covered. Because West Springs is largely new construction, the board is still settling and hairline cracking at corners is the normal first-year complaint.

How we install and seal it in West Springs

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 West Springs home. Poly on the walls with open boxes behind it is not a working vapour barrier, and it is the single most common thing we find on jobs that were started by someone else. Basement development is common in West Springs, and a basement behaves differently from the rest of the house — cooler, damper, and less forgiving of a rushed finish.

Common vapour barrier situations in West Springs

In West Springs, west Springs is a community still building out. Homes there are current-build, so ceilings are typically knockdown and the work is new-build boarding and taping, basement development, and the first-season movement that shows up as a house dries out. That is the standard on every job here, big or small — on-site quote, fixed price.

Why West Springs 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 West Springs.

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.

What we tend to find in West Springs

In a newly built West Springs home the drywall has not yet been through a full winter, so we plan the vapour barrier installation around settling that is still happening rather than settling that has finished.

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

In West Springs we are often the second trade to look at a wall, so the first question is what the original finish actually was.

Vapour Barrier West Springs: your questions answered

Does my basement development in West Springs need a vapour barrier?
Almost always, yes — exterior basement walls in our climate need a barrier on the warm side of the insulation before drywall. We confirm what your specific assembly needs on the site visit rather than guessing from the plan.
Which side of the insulation does the poly go on in a West Springs home?
The warm side — the side facing into the heated room. It is the detail that gets reversed most often, and it is not correctable once the wall is boarded.
Do you seal the outlet boxes and vents in West Springs?
Yes — every outlet, switch box, vent and pipe penetration gets sealed individually. Poly hung over open boxes looks finished and does not work.
Do I still need a vapour barrier in West Springs if I have spray foam?
Sometimes not — some spray foam assemblies act as their own barrier, and adding poly over them can be the wrong call. It depends on the product and the thickness, so we confirm on site instead of assuming.
Can you do the vapour barrier and the drywall together in West Springs?
Yes — insulation, vapour barrier and boarding as one job is the most common way we do it, and it means one crew is responsible for what ends up behind the wall. We also cover Pine Creek, Alpine Park, Osprey Hill and every Calgary quadrant.
