Frequently Asked Questions
Most jobs cost $1.25 to $3.50 a square foot, going by the area of the ceiling. Jobs that start with removal cost more, at $3.00 to $5.25. Your real number comes on paper after we have measured.
No. Cottages and houses come off the same rate sheet. Extra work, such as more sealing in a board ceiling, gets its own line on the quote.
The new-house target in Ontario is about R-60. Older houses and cottages often sit somewhere from R-12 to R-30, so most of them need more.
Usually not. A dry, clean layer stays, and the new fill goes on top. It comes out only when it is wet, mouldy or fouled by animals.
Yes. Blown-in fill can go in at any time of year, and the work stays in the attic. A winter visit also makes frost and warm spots easier to see.
Yes, within limits. The Home Renovation Savings program offers as much as $1,250 through its no-assessment attic route, though only jobs done by the companies it has already named qualify, and it has stopped naming more. A second route, built around an energy advisor's before-and-after visits, leaves the choice of company to you. Check the program's website for the current rules; we last checked them in October 2026.
Leave it alone and send a sample to a lab. If it contains asbestos, an asbestos abatement company removes it, and the new layer goes in after the space is clear.
It goes a long way. A sealed ceiling, a deep layer and open soffits together keep the roof cold enough that snow does not melt from the bottom.
Mice will nest in any fill they can get to. The fix is keeping them out of the building, and a wildlife control company can close the gaps on the outside walls and roof.
Most jobs are booked within a week or two of the visit. Fall is the busiest season, so calling earlier gives you more dates to pick from.

Attic Insulation Top-Up
Orillia's older houses mostly need an attic insulation top-up: fresh loose fill laid over the dry layer already up there, until the depth sits near R-60. For an older house, nothing gets the attic up to standard faster or for less money.
Steps and prices -
Blown-In Attic Insulation
Blown-in attic insulation is loose cellulose or fibreglass sent up a hose and spread across the whole ceiling, around every wire, box and joist. It reaches the spots that batts leave open.
Steps and prices -
Cottage Attic Insulation
Cottage attic insulation turns a thin summer ceiling into one that holds heat through a winter weekend. It is priced from the same rates we charge for a house in town.
Steps and prices -
Attic Insulation Removal
Attic insulation removal vacuums out old fill that is wet, mouldy, flattened or fouled by animals, so the ceiling can be air sealed and refilled from scratch. A large hose carries it from the attic to a collection unit or sealed bags outside.
Steps and prices -
Vermiculite Attic Insulation
Pebbly vermiculite attic insulation in an older house may contain asbestos, so a lab test always comes before any other step. Until the result is in, the safest choice is to leave it alone.
Steps and prices -
Attic Air Sealing
Attic air sealing in an Orillia house stops the warm, damp indoor air that slips up through gaps at lights, pipes and wires. We work from above, on the ceiling side, ahead of any new fill.
Steps and prices -
Ice Dam Prevention
Ice dam prevention works from under the roof, keeping the roof boards so cold that the snow on top stays frozen until spring. Sealing, depth and open soffits are the three tools.
