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.

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.

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 do I know I got the depth I paid for?

We leave depth markers through the attic so the installed depth can be read off by anyone afterwards. Depth is easy to claim and hard to check once the hatch is closed, which is exactly why we mark it.

Why does my Grovenor 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.

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 Grovenor house and the parts a general top-up misses.

Attic insulation in Grovenor: air seal first, then blow

The most common mistake in an Grovenor 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.

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

Keeping the eaves clear in an Grovenor attic

Ventilation and insulation are not opposites

An attic needs air moving from the soffits up to the ridge. Blowing loose-fill right into the eaves blocks that path, and a blocked attic gets damp regardless of how much insulation is in it.

Baffles

Baffles hold the insulation back so the soffit vents stay open. In older Grovenor homes they are often missing entirely, which is why the corners look thin — someone deliberately kept the insulation back, or it was never installed to the edge.

Grovenor drywall in context

About Grovenor

Lying in the City's west end, parts of Grovenor date back to the 1910s.

What we see in Grovenor

In Grovenor 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.

The attic hatch, which everybody forgets

A hole in the ceiling

The hatch in an Grovenor 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.

Adding to what is already there

You rarely start empty

Most Grovenor 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.

Ice damming and what the attic has to do with it

A heat problem, not a gutter problem

Ice at the eaves on an Grovenor roof usually means heat is escaping into the attic, melting snow on the upper roof, and that meltwater refreezing over the cold overhang.

Where the fix actually is

More heat tape rarely solves it. Sealing the air leaks and getting even insulation coverage right out to the eaves is what lowers the deck temperature. That is why we look at the attic when someone calls about ice, not at the roofline.

Storage in the attic and the insulation you lose

Boards over joists compress everything

Where a Grovenor 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.

Cellulose against fibreglass in an Grovenor 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.
