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.

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.

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.

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.

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.

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.

Attic Insulation Aldergrove Edmonton | Attic Top-Up

Attic top-ups in Aldergrove that hold their depth

Attics in Aldergrove 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.

Storage in the attic

An honest trade-off

Boards laid over the joists in an Aldergrove 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.

Aldergrove drywall in context

About Aldergrove

Planned in the 1970s, this area's multi-family dwellings on smaller lots were designed to help preserve agricultural land and conserve energy.

What we see in Aldergrove

In Aldergrove 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.

Pot lights, and which ones can be covered

Not all fixtures are equal

Older recessed fixtures in Aldergrove 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.

The attic hatch, which everybody forgets

A hole in the ceiling

The hatch in an Aldergrove home is often an uninsulated panel sitting in a frame with no weatherstrip. It is a direct opening between the house and a space that is at outdoor temperature.

What we do

The hatch gets insulated on its back face and weatherstripped so it seals when closed. It is a small job that shows up disproportionately in comfort, and it is the first place we look when someone says the hallway is cold.

Cellulose against fibreglass in an Aldergrove 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.

Depth, and how to check we delivered it

Verifiable rather than assumed

Blown insulation settles, and depth is easy to claim and hard to check once the hatch is closed. We leave depth markers through the Aldergrove attic so the installed depth can be read off later by anyone.

Even coverage

Depth is also an average — a deep drift in the middle and thin corners is not the same as an even blanket. Coverage to the edges is what actually reduces heat loss.

Sealing the ceiling below first

The order that matters

Warm moist air leaking from the house into a cold Aldergrove 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.
