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.

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.

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.

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.

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.

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.

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

The most common mistake in an Delwood 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.

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

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 Delwood 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.

Delwood drywall in context

About Delwood

Delwood is a mature, stable suburban neighbourhood featuring 90% single detached homes.

What we see in Delwood

In Delwood 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.

Attics over additions and vaulted areas

The awkward spaces

An Delwood addition often has a shallow attic, a cathedral section or a knee wall, and those areas are where insulation is thinnest and access is worst.

Why they matter disproportionately

They are frequently the coldest rooms in the house, and they are the parts a general top-up misses because the blower cannot reach them. We look at them specifically rather than quoting an average depth across the whole ceiling.

Keeping the eaves clear in an Delwood 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 Delwood 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.

Ventilation is not optional up there

Cold attic, by design

An Delwood 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.

Storage in the attic and the insulation you lose

Boards over joists compress everything

Where a Delwood 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.

Bathroom and kitchen fans venting into the attic

Found more often than you would think

In older Delwood 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.
