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.

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.

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 McCauley house and the parts a general top-up misses.

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.

How do I know I got the depth I paid for?

We leave depth markers through the attic so the installed depth can be read off by anyone afterwards. Depth is easy to claim and hard to check once the hatch is closed, which is exactly why we mark 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.

Attic Insulation McCauley Edmonton | Attic Top-Up

Attic top-ups in McCauley that hold their depth

The most common mistake in an McCauley 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.

Bathroom and kitchen fans venting into the attic

Found more often than you would think

In older McCauley 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.

McCauley drywall in context

About McCauley

McCauley, named in honour of Edmonton's first mayor (the colourful Matthew McCauley) developed primarily after 1908 when a street car line was started.

What we see in McCauley

In McCauley 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.

Ice damming and what the attic has to do with it

A heat problem, not a gutter problem

Ice at the eaves on an McCauley roof usually means heat is escaping into the attic, melting snow on the upper roof, and that meltwater refreezing over the cold overhang.

Where the fix actually is

More heat tape rarely solves it. Sealing the air leaks and getting even insulation coverage right out to the eaves is what lowers the deck temperature. That is why we look at the attic when someone calls about ice, not at the roofline.

Pot lights, and which ones can be covered

Not all fixtures are equal

Older recessed fixtures in McCauley ceilings need clearance and cannot be buried. Newer IC-rated fixtures are built to be in contact with insulation.

What we check

We identify what is installed before blowing. Where fixtures cannot be covered, they need boxing or replacing — and each one is also a significant air leak, so they are usually the first thing sealed regardless of type.

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

Stop and check first

Some older McCauley 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 eaves are where it goes thin

Geometry works against you

The roof meets the wall at the lowest point in the attic, so there is least room for insulation exactly where the wall below needs it most.

What it needs

Baffles that hold the insulation back from the soffit vents while still letting depth carry out over the wall plate. Skipping them in an McCauley attic either blocks the venting or leaves a cold band above every exterior wall.

Topping up against removing and replacing

Usually a top-up is fine

Old fibreglass in an McCauley 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.
