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.

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.

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

Do I need to seal before adding insulation?

Yes, and it is the part most often skipped. Warm moist air leaking from the house frosts the roof deck and wets the insulation. Blowing over unsealed pot lights and top plates buries the problem instead of fixing it.

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.

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.

Attic Insulation Crestwood Edmonton | Attic Top-Up

Attic top-ups in Crestwood that hold their depth

The most common mistake in an Crestwood 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
Attic hatch insulated and weatherstripped
Baffles kept clear so the soffit vents still breathe
Air sealing at pot lights, top plates and the attic hatch
Blown-in loose-fill to the depth your permit specifies

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 Crestwood 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.

Crestwood drywall in context

About Crestwood

Crestwood's unique street pattern provides excellent views of the river valley from the north, east, and south sides of the area.

What we see in Crestwood

In Crestwood 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.

Bathroom and kitchen fans venting into the attic

Found more often than you would think

In older Crestwood 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.

The attic hatch, which everybody forgets

A hole in the ceiling

The hatch in an Crestwood 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.

Storage in the attic

An honest trade-off

Boards laid over the joists in an Crestwood attic compress the insulation beneath them and create a thin band right through the middle of the ceiling.

What we suggest

A raised platform over a limited area if storage is genuinely needed, so the insulation depth continues underneath it. Or accepting that a full-depth attic is not also a storage room.

Topping up against removing and replacing

Usually a top-up is fine

Old fibreglass in an Crestwood 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.

Adding to what is already there

You rarely start empty

Most Crestwood 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.
