Does my basement development in Riversong need a vapour barrier?

Almost without exception, yes: exterior basement walls in Riversong require a barrier on the warm side of the insulation ahead of the drywall. Rather than reading it off the plan, we confirm on site in Riversong what that specific assembly needs.

Which side of the insulation does the poly go on in a Riversong home?

It goes warm side, facing into the heated room of the Riversong property. This is the detail most commonly installed the wrong way round in Riversong, and once the wall is boarded there is no fixing it.

Do you seal the outlet boxes and vents in Riversong?

Yes, individually: every box, vent and pipe penetration in a Riversong wall is sealed separately. Poly run over open boxes looks complete on a Riversong wall but does nothing.

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

Occasionally no: where a Riversong assembly uses spray foam that acts as its own barrier, adding poly can be wrong. The answer turns on the product and its thickness -- confirmed at the Riversong home, not guessed.

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

Yes, and it is how most Riversong work runs: insulation, vapour barrier and drywall as one job, with one crew accountable for what is behind it. We also cover Cochrane, Sunset Ridge, Heritage Hills and the Cochrane area.

Vapour barrier installation in Riversong, sealed before the board goes on

In a Riversong home the vapour barrier is invisible and unforgiving in equal measure -- board over a torn sheet or an open outlet box and it stays that way for the life of the wall. In Riversong 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. Riversong is a newer riverside Cochrane community where finishing and basement development are common, so basement development insulation is the main call here, with the main floors already insulated to a recent code. We cover Riversong and all of Cochrane, 7 days a week.

What affects the cost of vapour barrier installation in Riversong?

Area, penetrations and detailing

Vapour barrier cost in Riversong 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 Riversong 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. Riversong spans a range of build eras, so what is behind the wall differs street to street.

Where the vapour barrier goes in a Riversong wall, and why it is not a preference

The warm side, always

In Riversong the barrier goes on the warm side of the insulation — the side facing into the heated Riversong room. Its job in a Riversong wall is to stop indoor moisture reaching the cavity and condensing against cold framing.

What goes wrong when it is reversed

On the cold side, a barrier holds moisture inside the assembly instead of excluding it. It is one of the few mistakes in a Riversong wall that cannot be corrected without opening the wall back up, which is exactly why we check every Riversong job before anything is covered.

How we install and seal it in Riversong

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 Riversong home. Poly over open boxes does not make a functioning barrier, and on Riversong jobs started by others it is the number one thing we come across. In Riversong we see everything from original finishes to recent renovations on the same block.

Common vapour barrier situations in Riversong

In Riversong, riversong is a residential neighbourhood in Cochrane. Build years vary across the neighbourhood, so rather than assume what is behind the wall we confirm it on site — the finish, the texture and how the existing surface has aged all change how the repair is approached. That is the standard on every job here, big or small — on-site quote, fixed price.

Why Riversong 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 Riversong.

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 Riversong and all of Cochrane, 7 days a week. We quote Riversong jobs on site at no charge and fix the price before starting. Housing in Riversong is mixed, which is why we look before we quote rather than after.
