How much insulation should my attic have?

It is settled depth and even coverage that decide performance, not the product name. We set depth markers before blowing so the result is measurable, and check the corners rather than just the area near the hatch.

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 blow insulation over my pot lights?

Only if they are rated for contact with insulation. Older fixtures need clearance and have to be boxed or replaced. Either way they are significant air leaks, so they get sealed first.

Why does my Prince Rupert 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.

I store things in my attic. Can I keep doing that?

Yes, but the plywood squashes the insulation beneath it to joist depth. Either the storage area gets raised on a platform above the finished depth, or it stays as a deliberately weaker zone kept small. We will not top up around it and pretend it is not there.

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 Prince Rupert house and the parts a general top-up misses.

Blown-in attic insulation in Prince Rupert, sealed before it is filled

Attics in Prince Rupert lose depth over time — insulation settles, someone crawls through it for a wiring job, and the corners near the eaves are usually thin to begin with. A top-up is only worth doing if the baffles are clear and the ceiling below is sealed, so that is what we check before quoting.

Existing insulation levelled before the top-up
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
Blown-in loose-fill to the depth your permit specifies
Depth markers left in place so the result is verifiable

Bathroom and kitchen fans venting into the attic

Found more often than you would think

In older Prince Rupert 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.

Prince Rupert drywall in context

About Prince Rupert

Prince Rupert lies within the old Hudson Bay Company land reserve.

What we see in Prince Rupert

In Prince Rupert 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.

Adding to what is already there

You rarely start empty

Most Prince Rupert attics already have something, whether old batts, older loose fill, or both in layers.

When to top up and when not

If the existing material is dry, even and uncontaminated, adding over it is usually the best value. If it is wet, compacted, rodent-affected or hiding unsealed penetrations, removing it first is worth the cost, and we say which one we found.

Why air sealing comes before insulation in Prince Rupert

Insulation does not stop air

Batt and loose-fill slow heat transfer; neither stops air movement. In an Prince Rupert 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.

Ventilation is not optional up there

Cold attic, by design

An Prince Rupert 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.

Cellulose against fibreglass in an Prince Rupert 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.

Storage in the attic

An honest trade-off

Boards laid over the joists in an Prince Rupert attic compress the insulation beneath them and create a thin band right through the middle of the ceiling.

What we suggest

A raised platform over a limited area if storage is genuinely needed, so the insulation depth continues underneath it. Or accepting that a full-depth attic is not also a storage room.
