Attic insulation cost comes down to four things: attic floor area, the depth already there, the material chosen and whether old insulation must come out first.

We publish Ontario ranges here so the number does not come as a surprise. After the free inspection, your written estimate shows the true attic insulation cost for your house, task by task, which makes it easy to split the work across two seasons if you prefer.

Attic Insulation Cost details

Attic Insulation Cost By Type Of Job

Each figure below is a typical Ontario price for one square foot of attic.

Topping up over existing insulation runs $1.30 to $2.60.

Blowing cellulose over a thin or bare attic floor runs $1.50 to $2.80.

Sealing and insulating a century home attic, with extra hand work, runs $2.25 to $4.25.

Removing old insulation and replacing it runs $3.25 to $5.75.

Air sealing as a separate job runs $0.60 to $1.40, and sloped cathedral ceilings run $3.00 to $6.50, measured on the ceiling itself.

Attic Insulation Cost For A Typical Bolton House

Picture a newer Bolton house with a 1,200-square-foot attic holding eight inches of old fill. Raising that attic to R-60 would usually come in around $1,560 to $3,120, with another $700 to $1,700 if it needs sealing too.

What Raises Or Lowers Attic Insulation Cost

Tight headroom, steep roof pitches, balloon framing and a lot of hand work all raise the attic insulation cost, as does old fill that has to come out first.

A roomy, open attic with dry old insulation lowers it, since the new layer simply goes on top. Smaller jobs carry a minimum charge of about $1,100 to cover travel and setup.

Use The Calculator, Then Get The Written Number

The calculator on this page multiplies your attic area by these ranges. Treat it as a guide, since the written estimate after your free inspection shows the exact attic insulation cost. If a rebate is on your mind, the attic insulation rebate page is worth a read too.
