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.

How much insulation should my attic have?

It is settled depth and even coverage that decide performance, not the product name. We set depth markers before blowing so the result is measurable, and check the corners rather than just the area near the hatch.

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.

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.

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.

Blown-in attic insulation in Gariepy, sealed before it is filled

The most common mistake in an Gariepy 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.

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

Ventilation is not optional up there

Cold attic, by design

An Gariepy attic is meant to run close to outdoor temperature so the roof deck stays cold and snow does not melt and refreeze at the eaves.

The failure it prevents

Blocking soffit vents with insulation causes exactly the ice damming people add insulation to prevent. Air sealing the ceiling below and keeping the vents clear are two halves of the same job.

Gariepy drywall in context

About Gariepy

This area was named for Joseph Hormisdas Gariepy, an early pioneer merchant.

What we see in Gariepy

In Gariepy 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.

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 Gariepy 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.

What we can and cannot tell you about savings

Honest about the number

We will not quote you a percentage off your heating bill. It depends on your current depth, your air leakage, your windows, your furnace and how you heat the house.

What we will say

What the attic has now, what it would have after, and where the leaks are. Those are things we can measure and show you. A savings figure from a contractor who has not seen your utility bills is a sales number, not an estimate.

Storage in the attic and the insulation you lose

Boards over joists compress everything

Where a Gariepy 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.

Sealing the ceiling below first

The order that matters

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

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 Gariepy 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.
