Attic Insulation Questions From Bradford Homeowners

It is the smallest amount of insulation the building code allowed when the house went up. In plenty of Bradford homes that is well below R-60, and years of settling bring it lower still.

Most attic insulation jobs here cost $1.20 to $3.00 per square foot, or about $1,200 to $3,000 for an average subdivision attic. Taking old material out costs more. The free depth reading gives you a written price.

We build Bradford attics to R-60, about 17 to 22 inches of loose fill once it settles. The Ontario rebate program sets R-50 as its finishing target.

Details sit on our attic insulation rebate page.

That may be vermiculite, and some of it contains asbestos. Leave it undisturbed and mention it when you book. A lab test comes first, and if asbestos is found, an abatement contractor clears it before any insulation goes in.

Most Bradford top-ups wrap up in a single morning or afternoon. Pulling out an old layer and replacing it usually takes a day or two.
