Vapour barrier installation in Jensen, 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 Jensen 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. Jensen is an established Airdrie community where reno, repair and ceiling drywall are common, so basement development and the occasional upgrade where older insulation has settled or thinned are common here. We cover Jensen and all of Airdrie, 7 days a week.

What affects the cost of vapour barrier installation in Jensen?

Area, penetrations and detailing

Vapour barrier cost in Jensen 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 Jensen 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 Jensen the barrier goes on the warm side of the insulation — the side facing into the heated Jensen 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 Jensen wall that cannot be corrected without opening the wall back up, which is exactly why we check every Jensen job before anything is covered. Basement development is common in Jensen, and a basement behaves differently from the rest of the house — cooler, damper, and less forgiving of a rushed finish.

How we install and seal it in Jensen

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 Jensen 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 Jensen, 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 Jensen

From the first patch to a finished basement, Jensen is one of the areas we serve every week. We replace water-damaged drywall, fix stained ceilings and blend the texture invisibly, with insurance photos. We handle renovation and new-construction drywall, boarding and finishing on schedule. Fast, clean and paint-ready, most repairs in a single visit. That is the standard on every job here, big or small — on-site quote, fixed price.

Why Jensen 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 Jensen.

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.

Jensen: what shapes the job

In Jensen we see original finishes and recent renovations on the same block, so the vapour barrier installation is scoped per house, not per postcode.

A lot of the work in Jensen starts in the basement, where the ceiling has to stay openable for the plumbing and ducting above it.

Vapour Barrier Jensen: your questions answered

Does my basement development in Jensen 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 Jensen 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 Jensen?
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 Jensen 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 Jensen?
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 Bayside, Kings Heights, Coopers Crossing and the Airdrie area.
Do you do small drywall repairs in Jensen or only big jobs?
Both — from a single patch, crack or nail-pop repair in Jensen (often done in one visit) up to full basement finishing and renovations.
