Attic insulation cost in Barrhaven depends on the attic's floor area, the depth you add, the sealing needed and whether old material comes out first.
Each of those parts gets its own line on the written quote, so every dollar has a label. The ranges below are Ontario market figures, and the quote after the visit is the real number for your house.
Attic Insulation Cost details
Typical Attic Insulation Cost By Job
Topping up an existing layer is usually $1.40 to $2.60 per square foot. Taking a nearly bare attic to R-60 is about $2.00 to $3.20. Air sealing combined with a top-up comes to roughly $1.90 to $3.40, and stripping old material before a full refill lands near $3.20 to $5.80.
Rooms over garages are about $2.50 to $4.50 per square foot of floor, and cathedral ceilings about $3.50 to $7.00. The smallest job we take on is $1,100.
Attic Insulation Cost For Common Barrhaven Homes
A townhouse attic of about 600 to 800 square feet often costs $1,100 to $2,000 for sealing and a top-up. A detached two-story home with a 1,000 to 1,300 square foot attic often lands between $1,800 and $3,500. Larger homes in Stonebridge or around Manotick cost more because of the area and the more complex roof lines.
What Changes Attic Insulation Cost
The number of pot lights and other ceiling openings changes the sealing time. A hatch in a tight closet slows the work. Low roofs at the eaves take longer to reach. Mouse damage or wet insulation adds removal. A clean, dry existing layer lowers the price, because it is left where it is and added to the depth.

Attic ventilation moves outside air in at the soffits and out near the ridge, so the attic stays cold and dry in winter and less hot in summer.
