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.

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 CPR Irvine house and the parts a general top-up misses.

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.

Attic Insulation CPR Irvine Edmonton | Attic Top-Up

Attic top-ups in CPR Irvine that hold their depth

Attics in CPR Irvine 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.

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

Adding to what is already there

You rarely start empty

Most CPR Irvine 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.

What we see in CPR Irvine

In CPR Irvine the drywall work is first-year settling, basement dev for first owners, Level 5 over builder-grade. 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 CPR Irvine 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 CPR Irvine 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.

Insulating a CPR Irvine attic with knob-and-tube or old wiring

Stop and check first

Some older CPR Irvine homes still carry active knob-and-tube wiring in the attic. Burying it in insulation is not something we do — it needs an electrician to assess and usually to replace before the attic is filled.

Why we raise it

It is the kind of thing found halfway through a job, and it is far cheaper to find at the quote. If we see it, we tell you and we stop until it is dealt with.

Sealing the ceiling below first

The order that matters

Warm moist air leaking from the house into a cold CPR Irvine 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 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 CPR Irvine attic either blocks the venting or leaves a cold band above every exterior wall.
