Two numbers drive attic insulation cost: how many square feet the attic floor covers and how many inches it needs. You get the going rate when you call and a firm written price after the free check.

At Ontario market rates, attic insulation cost usually lands between $1.25 and $3 per square foot of attic floor.

Attic Insulation Cost Details

Typical Attic Insulation Cost By Job

These are Ontario market ranges, not quotes. Topping up an existing layer to R-60 runs about $1.25 to $2.75 per square foot, and filling an empty attic with cellulose about $1.75 to $3. Taking out old insulation adds about $1.50 to $3.50 per square foot.

Air sealing is often priced per job, at roughly $400 to $1,500. Small jobs start at about $1,200.

Attic Insulation Cost For Common Orléans Homes

The attic insulation cost for a 1,200 square foot bungalow or two-story attic that needs a top-up often lands between $1,500 and $3,300. A townhome attic is smaller, but a narrow hatch and party walls can add time.

Use the estimator on this page for a first attic insulation cost range, then book the check for the real number.

What Raises Or Lowers Attic Insulation Cost

Easy access, an open attic and a solid old layer keep the price down. Low roofs, a tiny hatch, lots of ceiling openings, wet or dirty insulation, and missing baffles push it up.

Every one of those items appears as its own line on the quote. If you want to start with the coldest part of the house, we can price that area alone.

The Written Quote Holds

Your attic insulation cost is the figure on the signed quote unless you ask for more work. If something hidden turns up mid-job, like a bath fan blowing into the attic, we stop, show you, and price it before going further.

Attic Insulation Top-Up To R-60

An attic insulation top-up blows fresh cellulose over the layer already in place and lifts the attic to R-60. For a chilly top floor in an older Orléans house, it is the quickest fix there is.

Cellulose Attic Insulation

Cellulose attic insulation is blown in as loose fill and settles into a dense, even layer across the whole attic floor. It reaches the low corners at the eaves where batts often stop short.

Old Attic Insulation Removal

Attic insulation removal pulls out old fill that is flattened, dirty or damaged, so the attic can be sealed and refilled properly. It leaves through a sealed vacuum hose and goes away in bags.

Attic Air Sealing

Attic air sealing plugs the openings between your living space and the attic above. Heated air rises out through pot lights, wire holes, vent stacks and the hatch, carrying moisture along with it.

Ice Dam Prevention

Ice dams start when warmth leaking out of the house softens roof snow from underneath and the water freezes again at the cold overhang. Ice dams then hold back more meltwater, which can creep under the shingles and stain the ceiling.

Wet And Mouldy Insulation

Wet attic insulation holds little heat, and left damp it can feed mould on the roof boards. We find out where the water came from, take out the damaged material, and reinsulate once the wood is dry.

Vermiculite Insulation

Vermiculite insulation is a light, pebbly loose fill in silver-gold to grey-brown. Some vermiculite insulation sold in Canada before 1990, including the Zonolite brand, came from a mine with natural asbestos in it. Not all of it contains asbestos, and nobody can tell by looking.

Attic Insulation Rebate

The Ontario attic insulation rebate comes from the Home Renovation Savings program, run across the province by Save on Energy together with Enbridge Gas. Its attic-only stream pays up to $1,250 once a thin attic is brought to R-50, and it does not ask for a home energy assessment first.
