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

Vapour barrier installation in Evergreen, 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 Evergreen 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. Evergreen is an SW Calgary community with a mix of older homes and newer builds, so insulation calls here range from basement development in the newer homes to attic and wall upgrades in the older ones nearby. We cover Evergreen, Pine Creek, Alpine Park, Osprey Hill and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Evergreen?

Area, penetrations and detailing

Vapour barrier cost in Evergreen 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 Evergreen 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 Evergreen the barrier goes on the warm side of the insulation — the side facing into the heated Evergreen 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 Evergreen wall that cannot be corrected without opening the wall back up, which is exactly why we check every Evergreen job before anything is covered. Knockdown is the standard ceiling texture through Evergreen, so a patch gets tested for match before the whole ceiling is sprayed.

How we install and seal it in Evergreen

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 Evergreen 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. Much of Evergreen carries an orange-peel finish, which is easy to apply and unforgiving to match badly.

Common vapour barrier situations in Evergreen

In Evergreen, evergreen is a community built out in the 2000s. Homes of that vintage generally have knockdown ceilings and orange-peel walls, and the common calls are settling cracks, nail pops and basement development. That is the standard on every job here, big or small — on-site quote, fixed price.

Why Evergreen 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 Evergreen.

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 Evergreen and every Calgary quadrant, 7 days a week. Free on-site quotes and a fixed price before any work starts.

In Evergreen

What vapour barrier installation usually involves in Evergreen

Housing in Evergreen is mixed enough that two jobs on the same street can need completely different vapour barrier installation work.

Orange peel is common on Evergreen walls. It is quick to apply and unforgiving to match, so the tip and the timing matter more than the mud.

Ceilings here are typically knockdown, and matching that spray pattern is the part people notice if it is done badly — so we test the match before committing to the whole ceiling.

FAQ — Vapour Barrier Evergreen

Vapour Barrier Evergreen: your questions answered

Does my basement development in Evergreen 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 Evergreen 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 Evergreen?
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 Evergreen 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 Evergreen?
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.
