Vapour barrier installation in Silverado, 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 Silverado 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. Silverado 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 Silverado, Pine Creek, Alpine Park, Osprey Hill and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Silverado?

Area, penetrations and detailing

Vapour barrier cost in Silverado 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 Silverado 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. Basement development is common in Silverado, and a basement behaves differently from the rest of the house — cooler, damper, and less forgiving of a rushed finish.

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

The warm side, always

In Silverado the barrier goes on the warm side of the insulation — the side facing into the heated Silverado 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 Silverado wall that cannot be corrected without opening the wall back up, which is exactly why we check every Silverado job before anything is covered.

How we install and seal it in Silverado

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 Silverado 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. In Silverado basements the deciding detail is usually access: what has to stay reachable once the ceiling is closed up.

Common vapour barrier situations in Silverado

Basement development is a popular first or second project for Silverado owners once they have settled in — we board, tape, mud and finish to a smooth, paint-ready Level 4 or 5 to match the upstairs. That is the standard on every job here, big or small — on-site quote, fixed price.

Why Silverado 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 Silverado.

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 Silverado and every Calgary quadrant, 7 days a week. Free on-site quotes and a fixed price before any work starts. A lot of our Silverado work starts in the basement, where the ceiling has to stay openable for the plumbing above it.

What vapour barrier installation usually involves in Silverado

Silverado 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.

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

Vapour Barrier Silverado: your questions answered

Does my basement development in Silverado 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 Silverado 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 Silverado?
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 Silverado 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 Silverado?
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.
Our Silverado builder used a basic wall finish — can you upgrade it before we paint?
Yes — smoothing builder-grade walls to Level 5 before the first repaint is one of our most common Silverado requests, especially in rooms with strong window or pot light.
