Attic Insulation Top-Up In Orillia, Ontario
Ontario attic rebates up to $1,250 may apply
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.
The old layer is checked first. When it is dry, clean and free of droppings, it stays put and forms the base of the new depth. When it is wet or fouled, it comes out before anything else happens.
Attic Insulation Top-Up details
Why An Attic Insulation Top-Up Is Often Needed
Loose fill sinks a little every year, and batts sag or get kicked aside whenever someone crawls through. An attic filled to R-28 in the 1980s may hold a good deal less today.
An attic insulation top-up puts back the depth those years have taken. Most houses we measure near downtown Orillia need another eight to twelve inches to reach about R-60.
Seal The Ceiling First, Then Add Depth
Openings in the ceiling let warm, damp air rise straight through any depth of fill. We close them before the attic insulation top-up, while the joists are still in plain view.
Once a foot of new fill covers everything, those holes are buried and nearly impossible to find. Doing attic air sealing at the start lets the new depth do its full job.
Rulers Show The Depth Of Every Attic Insulation Top-Up
Before blowing starts, we stand depth rulers at several spots across the attic, each marked with the target from the written quote. They stay behind after we leave, so you can look at them from the hatch whenever you like.
The attic insulation top-up is spread evenly over the whole space. Vent chutes go in at the eaves first, so the added depth never smothers the soffit vents.
Attic Insulation Top-Up Prices
An attic insulation top-up usually lands at $1.25 to $2.25 for every square foot the attic covers. A 1,000 square foot attic usually comes to $1,250 to $2,250, plus any sealing listed separately. The attic insulation cost page has the full rate sheet.

Work That Often Goes With This One
Several of these are usually done on the same day.
-
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.
