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 Queen Alexandra house and the parts a general top-up misses.

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.

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.

Why does my Queen Alexandra 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.

Will insulating my attic stop the ice at my eaves?

Often it helps a great deal, because ice damming is usually escaping heat melting snow that then refreezes over the cold overhang. Air sealing plus even coverage to the eaves lowers the deck temperature, which is the actual cause.

How much will this save me on heating?

We will not put a percentage on it. Too much depends on your air leakage, windows and furnace. We will tell you what depth you have now, what you would have after, and where the leaks are — those we can actually measure.

Attic Insulation Queen Alexandra Edmonton | Attic Top-Up

Attic top-ups in Queen Alexandra that hold their depth

Attics in Queen Alexandra 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.

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

Sealing the ceiling below first

The order that matters

Warm moist air leaking from the house into a cold Queen Alexandra 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.

Queen Alexandra drywall in context

About Queen Alexandra

Queen Alexandra, named for the wife of Edward VII of England, was once part of the original Town of Strathcona.

What we see in Queen Alexandra

In Queen Alexandra 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 Queen Alexandra 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 Queen Alexandra

Insulation does not stop air

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

Topping up against removing and replacing

Usually a top-up is fine

Old fibreglass in an Queen Alexandra 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.

Pot lights, and which ones can be covered

Not all fixtures are equal

Older recessed fixtures in Queen Alexandra 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.

Storage in the attic and the insulation you lose

Boards over joists compress everything

Where a Queen Alexandra homeowner has laid plywood across the joists for storage, the insulation beneath is squashed to joist depth. That strip performs at a fraction of the rest of the attic.

Options

Either the storage area is raised on a platform above the finished insulation depth, or it is accepted as a deliberately weaker zone kept as small as possible. What does not work is topping up around it and pretending the platform is not there.
