Does my basement development in Garrison Woods need a vapour barrier?

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

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

Do you seal the outlet boxes and vents in Garrison Woods?

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

Do I still need a vapour barrier in Garrison Woods if I have spray foam?

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

Can you do the vapour barrier and the drywall together in Garrison Woods?

Yes -- running insulation, barrier and boarding as a single Garrison Woods job is our usual approach, and it puts one crew on the hook for what ends up in the wall. We also cover Pine Creek, Alpine Park, Osprey Hill and every Calgary quadrant.

Vapour barrier installation in Garrison Woods, sealed before the board goes on

Few parts of a Garrison Woods build are as completely concealed, or as unforgiving, as the vapour barrier; once boarded, a torn sheet or unsealed box is permanent. In Garrison Woods 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. Garrison Woods is an inner-SW Calgary community of late-1990s/2000s builds where Level 5 finish and reno drywall are common, so basement development insulation is the main call here, with the main floors already insulated to a recent code. We cover Garrison Woods, Pine Creek, Alpine Park, Osprey Hill and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Garrison Woods?

Area, penetrations and detailing

Vapour barrier cost in Garrison Woods 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 Garrison Woods 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 Garrison Woods home, and why it is not negotiable

The warm side, always

In Garrison Woods the barrier goes on the warm side of the insulation — the side facing into the heated Garrison Woods room. That is how indoor moisture is prevented from moving into a Garrison Woods 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 Garrison Woods wall that cannot be corrected without opening the wall back up, which is exactly why we check every Garrison Woods job before anything is covered. In older Garrison Woods houses it is worth knowing whether there is lath behind the wall before anything is cut.

How we install and seal it in Garrison Woods

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 Garrison Woods 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 Garrison Woods jobs. In older Garrison Woods houses it is worth knowing whether there is lath behind the wall before anything is cut.

Common vapour barrier situations in Garrison Woods

In Garrison Woods, we treat every Garrison Woods job as its own case rather than a standard package — a character home this age can hide anything behind the wall, from original horsehair lath to a 1970s drywall retrofit, and the right repair depends on which one we actually find. Same trusted team, same process on every job — on-site quote, fixed price, no surprises.

Why Garrison Woods 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 Garrison Woods.

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