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.

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.

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 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.

Should I block the vents to stop drafts?

No. The attic is meant to run close to outdoor temperature so the roof deck stays cold. Blocking soffit vents causes exactly the ice damming people add insulation to prevent.

Why is the area above my exterior walls always cold?

Geometry. The roof meets the wall at the lowest point in the attic, so there is least room exactly where it is needed most. Baffles hold insulation back from the soffit vents while letting depth carry over the wall plate.

Attic Insulation Lee Ridge Edmonton | Attic Top-Up

Attic insulation in Lee Ridge: air seal first, then blow

Attics in Lee Ridge 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
Attic hatch insulated and weatherstripped
Blown-in loose-fill to the depth your permit specifies
Depth markers left in place so the result is verifiable
Air sealing at pot lights, top plates and the attic hatch
Existing insulation levelled before the top-up

Pot lights, and which ones can be covered

Not all fixtures are equal

Older recessed fixtures in Lee Ridge 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.

Lee Ridge drywall in context

About Lee Ridge

Lee Ridge, named for Robert Lee (Mayor of Edmonton, 1909 - 1910), is one of the 27 neighbourhoods of Mill Woods.

What we see in Lee Ridge

In Lee Ridge 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 Lee Ridge 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.

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 Lee Ridge 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.

Topping up against removing and replacing

Usually a top-up is fine

Old fibreglass in an Lee Ridge 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.

Why air sealing comes before insulation in Lee Ridge

Insulation does not stop air

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

Cellulose against fibreglass in an Lee Ridge 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.
