Does my basement development in Legacy need a vapour barrier?

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

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

Do you seal the outlet boxes and vents in Legacy?

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

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

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

Can you do the vapour barrier and the drywall together in Legacy?

Yes -- running insulation, barrier and boarding as a single Legacy 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 Legacy, sealed before the board goes on

Few parts of a Legacy build are as completely concealed, or as unforgiving, as the vapour barrier; once boarded, a torn sheet or unsealed box is permanent. In Legacy 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. Legacy 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 Legacy, Pine Creek, Alpine Park, Osprey Hill and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Legacy?

Area, penetrations and detailing

Vapour barrier cost in Legacy 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 Legacy 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. In Legacy basements the deciding detail is usually access: what has to stay reachable once the ceiling is closed up.

Vapour barrier placement in a Legacy home, and why it is not negotiable

The warm side, always

In Legacy the barrier goes on the warm side of the insulation — the side facing into the heated Legacy room. That is how indoor moisture is prevented from moving into a Legacy 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 Legacy wall that cannot be corrected without opening the wall back up, which is exactly why we check every Legacy job before anything is covered. Knockdown is the standard ceiling texture through Legacy, so a patch gets tested for match before the whole ceiling is sprayed.

How we install and seal it in Legacy

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 Legacy 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 Legacy jobs. New homes in Legacy tend to have long unbroken wall runs and high ceilings, which changes how a seam has to be feathered.

Common vapour barrier situations in Legacy

In Legacy, legacy 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. One fixed price after an honest on-site look, and the job done right the first time.

Why Legacy 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 Legacy.

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 Legacy and every Calgary quadrant, 7 days a week. On-site quoting in Legacy costs nothing, and the price is set before anything starts. Ceilings in Legacy are typically knockdown, and matching that pattern is the part of a repair people notice.

In Legacy

What we tend to find in Legacy

In a newly built Legacy 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.

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

Knockdown is the standard ceiling texture through Legacy, which means the repair is judged on texture match as much as on whether the surface is flat.
