Does my basement development in Altadore need a vapour barrier?

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

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

Do you seal the outlet boxes and vents in Altadore?

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

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

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

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

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

Few parts of a Altadore build are as completely concealed, or as unforgiving, as the vapour barrier; once boarded, a torn sheet or unsealed box is permanent. In Altadore 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. Altadore is an older SW Calgary community where settling cracks, aging texture and the occasional plaster repair come up, so attic top-ups and wall insulation upgrades are common here alongside basement development, since original insulation levels are often below current standards. We cover Altadore, Pine Creek, Alpine Park, Osprey Hill and every Calgary quadrant, 7 days a week.

What affects the cost of vapour barrier installation in Altadore?

Area, penetrations and detailing

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

The warm side, always

In Altadore the barrier goes on the warm side of the insulation — the side facing into the heated Altadore room. That is how indoor moisture is prevented from moving into a Altadore 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 Altadore wall that cannot be corrected without opening the wall back up, which is exactly why we check every Altadore job before anything is covered. Altadore has infill builds next door to original houses, so two homes on one street can need completely different work.

How we install and seal it in Altadore

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 Altadore 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 Altadore jobs. Some Altadore homes are plaster rather than drywall behind the paint, which changes the repair entirely.

Common vapour barrier situations in Altadore

In Altadore, in an established, older community like Altadore we spend a lot of time repairing cracked and settled plaster, refinishing tired walls and ceilings, and blending patches into original textured surfaces — plus new-construction drywall on the infill homes replacing original lots. Same trusted team, same process on every job — on-site quote, fixed price, no surprises.

Why Altadore 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 Altadore.

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

How Altadore homes affect the work

Altadore has been through many freeze-thaw cycles, so before quoting vapour barrier installation we look at whether a crack is old movement that has stopped or something still opening.

Altadore has infill builds next to original houses, so two homes a few doors apart can need completely different work.

Some Altadore homes are plaster rather than drywall behind the paint, which changes the repair entirely — different backing, different bonding, different failure mode.
