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 works
From a one-day top-up in a Bolton subdivision to a slow, careful job in a century farmhouse, all nine of our services open with a free inspection.
Each page explains how that attic insulation job gets done and what it typically costs in Ontario.

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 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.
How old fill is removed
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.
Price ranges by jobChoose a job, enter how many square feet your attic floor covers and a typical Ontario range appears. The free inspection later narrows it to one written price.
Treat these as provincial market figures, not a firm price. Existing depth, access and any removal shift the figure, and most jobs start at about $1,100.
Typical installed range
The free inspection tells you what is above your ceiling today and which job would make the biggest difference.
