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.

Can I add over the old insulation?

Usually yes, if it is dry, even and uncontaminated. If it is wet, compacted, rodent-affected or hiding unsealed penetrations, removing it first is worth the cost, and we tell you which one we found.

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.

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 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 Sweet Grass 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.

Attic Insulation Sweet Grass Edmonton | Attic Top-Up

Attic insulation in Sweet Grass: air seal first, then blow

Attics in Sweet Grass 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

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 Sweet Grass attic either blocks the venting or leaves a cold band above every exterior wall.

Sweet Grass drywall in context

About Sweet Grass

The neighbourhood is named in honour of the Cree Indian Chief Sweet Grass who was one of the early west's first conservationists and instrumental in the protection of the Plains Bison.

What we see in Sweet Grass

In Sweet Grass 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.

Why air sealing comes before insulation in Sweet Grass

Insulation does not stop air

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

The attic hatch nobody insulates

A hole in the ceiling

An uninsulated, unsealed hatch is a direct opening between the heated house and a cold attic, and it is often the single worst detail in an otherwise good Sweet Grass ceiling.

Simple fix

An insulated cover with weatherstripping and a dam around the opening so blown insulation does not spill through when it is opened.

Depth is the whole number

What you are buying

Attic performance is almost entirely a function of settled depth and even coverage. Two attics with the same product can perform very differently.

How we handle it

Depth markers are set before blowing so the result is measurable rather than asserted, and the Sweet Grass attic is checked at the corners rather than only where the hatch is. An attic that is deep in the middle and thin at the perimeter is the usual finding.

Bathroom and kitchen fans venting into the attic

Found more often than you would think

In older Sweet Grass 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.

Storage in the attic and the insulation you lose

Boards over joists compress everything

Where a Sweet Grass 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.
