Do you insulate the attic hatch too?

Yes. It is a direct opening between the house and a space at outdoor temperature, and it is usually the first place we look when someone says a hallway or landing is cold.

My bathroom fan seems to vent into the attic. Is that a problem?

Yes, and it needs correcting before insulating. It dumps warm wet air into the coldest part of the house, and burying it under fresh insulation hides a moisture source that will show up later as frost and staining.

Cellulose or fibreglass?

Both work when installed to depth with the ceiling sealed underneath. Cellulose is denser and resists air movement better; fibreglass is lighter and settles less. We pick based on what is already up there and tell you why.

Can you just blow on top of what is already there?

Usually yes, if the existing insulation is dry, undisturbed and not contaminated. If it is wet or shows rodent activity it comes out first, because topping over that seals the problem in rather than fixing it.

Why does my Allendale attic frost up in winter?

Almost always warm moist air leaking up from the house through pot lights, top plates or the hatch, then condensing on cold sheathing. More insulation on its own does not fix it — the leaks have to be sealed first.

Can I add over the old insulation?

Usually yes, if it is dry, even and uncontaminated. If it is wet, compacted, rodent-affected or hiding unsealed penetrations, removing it first is worth the cost, and we tell you which one we found.

Attic insulation in Allendale: air seal first, then blow

The most common mistake in an Allendale attic is blowing insulation over an unsealed ceiling. Warm moist air keeps rising through pot lights, top plates and the hatch, and it carries moisture into cold insulation where it condenses. We air-seal the penetrations first, then insulate.

Why air sealing comes before insulation in Allendale

Insulation does not stop air

Batt and loose-fill slow heat transfer; neither stops air movement. In an Allendale attic warm moist household air rises through pot lights, top plates and the hatch, passes straight through the insulation and condenses when it hits the cold deck.

What that looks like later

Frost on the underside of the sheathing in February, then staining on the ceiling in spring. Sealing the penetrations first is the difference between insulation that works and insulation that becomes the problem.

Allendale drywall in context

About Allendale

Once farmed by the Allen family, this area was annexed by the City of Strathcona in 1907 and became part of Edmonton in 1912 when Strathcona and Edmonton amalgamated.

What we see in Allendale

In Allendale the drywall work is plaster and lath repair, popcorn and stipple ceiling removal, careful patching into original surfaces. We confirm what your home actually needs on site, in writing, before anything starts.

Bathroom and kitchen fans venting into the attic

Found more often than you would think

In older Allendale homes a bathroom fan is frequently ducted into the attic space rather than through the roof or soffit. It dumps warm wet air straight into the coldest part of the house.

Why it matters before insulating

Burying that under fresh loose-fill hides a moisture source that will show up as frost and staining. If we find one we tell you, because it needs correcting first — insulation on top of it makes it harder to reach and harder to diagnose.

Sealing the ceiling below first

The order that matters

Warm moist air leaking from the house into a cold Allendale attic is what frosts the underside of the roof deck and wets the insulation.

Where it leaks

The hatch, pot lights, bath fans, plumbing stacks and the top plates of interior walls. Blowing more insulation over unsealed penetrations buries the problem instead of fixing it, so sealing comes first.

Topping up against removing and replacing

Usually a top-up is fine

Old fibreglass in an Allendale attic that is dry and undisturbed can be levelled and topped up. It still insulates, and removing it is a large cost for a small gain.

When it has to come out

Insulation that is wet, contaminated, or full of rodent activity gets removed rather than buried, because topping over it seals the problem in. We will tell you which of the two you have after looking, not before.

Ventilation is not optional up there

Cold attic, by design

An Allendale attic is meant to run close to outdoor temperature so the roof deck stays cold and snow does not melt and refreeze at the eaves.

The failure it prevents

Blocking soffit vents with insulation causes exactly the ice damming people add insulation to prevent. Air sealing the ceiling below and keeping the vents clear are two halves of the same job.

Insulating a Allendale attic with knob-and-tube or old wiring

Stop and check first

Some older Allendale homes still carry active knob-and-tube wiring in the attic. Burying it in insulation is not something we do — it needs an electrician to assess and usually to replace before the attic is filled.

Why we raise it

It is the kind of thing found halfway through a job, and it is far cheaper to find at the quote. If we see it, we tell you and we stop until it is dealt with.
