Attic Insulation Top-Up
An attic insulation top-up builds a new layer of loose fill over the old one, bringing a shallow attic floor up to R-60.
How a top-up worksAttic insulation removal clears away fill that is soaked, mouldy, flattened or fouled by mice, squirrels or raccoons, leaving a clean attic ready for sealing and new material.
The work is done with an industrial vacuum. Old fill rides a long hose out to a collection bag in the driveway, and nothing dirty is walked through your hallways.
Removal is the right call when the old layer is stained, smells musty, holds droppings or was flattened by a roof leak. Nests and tunnels left by wildlife are another clear sign.
Dry, clean fill can usually stay, and a cheaper attic insulation top-up over it gives better value.
Vermiculite resembles grey-brown or golden gravel and may contain asbestos, so it is never vacuumed or stirred up until a sample has been tested.
If the lab finds asbestos, the removal belongs to an abatement contractor working under Ontario Regulation 278/05, and new fill is installed after that crew is done. A clean result lets the vacuum work go ahead as usual.
With the old fill gone, the attic floor is bare, and each pot light, pipe, wire hole and wall top sits in plain view.
That is the best moment for complete attic air sealing, followed by baffles and fresh loose fill blown to R-60.
Attic insulation removal plus new fill generally costs between $3.25 and $5.75 a square foot in Ontario, which puts a 1,200-square-foot attic near $3,900 to $6,900 with sealing included.
Phone (289) 210-8354 so we can inspect the old layer before any attic insulation removal is booked. The Caledon attic insulation home page covers everything else.
Booking two of these on the same day spares you a second round of setup.

How a top-up works
Blown-in cellulose insulation lays one continuous blanket across the attic floor and reaches into every corner, in new and old houses alike.
How cellulose is blown in
Century home attic insulation starts with a longer inspection, because a house past its hundredth birthday hides problems a newer home never has.
Details for older homes
Attic air sealing plugs the small openings where heated room air escapes upward through the ceiling, and it opens every job we take on.
Where the leaks get sealed
Ice dam prevention is most effective from inside the attic, where the goal is a roof deck too cold to melt the snow sitting on it.
How ice dams are stopped
Cathedral ceiling insulation goes into the thin space above an angled ceiling, where there is no open attic floor to work from.
Options for sloped ceilings
Ontario's attic insulation rebate is one stream of Home Renovation Savings, a program Save on Energy and Enbridge Gas run together, and it refunds a share of the bill once an attic reaches R-50 or more.
Rebate routes and amounts
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.
