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.

Do you insulate over an addition or a vaulted ceiling?

Those need looking at specifically rather than quoting an average depth. Shallow attics, cathedral sections and knee walls are usually the coldest rooms in an Westmount house and the parts a general top-up misses.

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.

Do I need to seal before adding insulation?

Yes, and it is the part most often skipped. Warm moist air leaking from the house frosts the roof deck and wets the insulation. Blowing over unsealed pot lights and top plates buries the problem instead of fixing it.

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.

Will you block my soffit vents?

No. Baffles hold the insulation back at the eaves so air can still move from the soffits to the ridge. A blocked attic gets damp no matter how much insulation is in it.

Attic insulation in Westmount: air seal first, then blow

The most common mistake in an Westmount 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.

Depth markers left in place so the result is verifiable
Blown-in loose-fill to the depth your permit specifies
Attic hatch insulated and weatherstripped
Baffles kept clear so the soffit vents still breathe
Air sealing at pot lights, top plates and the attic hatch
Existing insulation levelled before the top-up

Depth is the whole number

What you are buying

Attic performance is almost entirely a function of settled depth and even coverage. Two attics with the same product can perform very differently.

How we handle it

Depth markers are set before blowing so the result is measurable rather than asserted, and the Westmount attic is checked at the corners rather than only where the hatch is. An attic that is deep in the middle and thin at the perimeter is the usual finding.

Westmount drywall in context

About Westmount

Westmount likely takes its name from an affluent, predominantly Anglophone, city on the west island of Montreal.

What we see in Westmount

In Westmount 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.

Ventilation is not optional up there

Cold attic, by design

An Westmount 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.

Bathroom and kitchen fans venting into the attic

Found more often than you would think

In older Westmount 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.

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

Stop and check first

Some older Westmount 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.

The attic hatch nobody insulates

A hole in the ceiling

An uninsulated, unsealed hatch is a direct opening between the heated house and a cold attic, and it is often the single worst detail in an otherwise good Westmount ceiling.

Simple fix

An insulated cover with weatherstripping and a dam around the opening so blown insulation does not spill through when it is opened.

Cellulose against fibreglass in an Westmount attic

Two products, different behaviour

Blown cellulose is denser, settles into gaps well and resists air movement through it better. Blown fibreglass is lighter, does not settle as much over time and is less prone to holding moisture.

How we choose

Either performs when installed to the right depth with the ceiling sealed underneath. We pick based on what is already up there and how the attic is built, and we tell you which we would use and why rather than defaulting to whichever is on the truck.
