Attic Insulation York Edmonton

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

Attics in York 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
• Existing insulation levelled before the top-up
• Attic hatch insulated and weatherstripped
• Air sealing at pot lights, top plates and the attic hatch
• Depth markers left in place so the result is verifiable
• Baffles kept clear so the soffit vents still breathe

Attic Insulation York Edmonton: your questions answered

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

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.

Why does my York 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.

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.

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.
