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
Caledon Attic Insulation air seals and insulates attics for households in Bolton, Caledon East and the smaller Caledon villages. All the work we do is fully insured. The way we work grew out of the houses here, where a farmhouse from the 1880s and a house finished last spring can share the same concession road.
Older homes receive a slower, more thorough attic inspection than most companies offer. That extra time is how we uncover open wall tops, old wiring and hidden leaks, the very things that decide whether new insulation will perform.
Each job opens with a free attic inspection. Depth readings are taken in several bays, the vents and hatch are looked over, and anything that needs attention is photographed.
Your written estimate is drawn up from that visit. It names the material, the finished depth, the R-value and each sealing task, and a price sits beside every line.
Sealing always comes ahead of the new fill. A leaky ceiling lets both warmth and humidity rise into the attic, and piling on more depth will not stop air that is on the move.
Lights, pipes, wire holes, wall plates and the hatch are closed off and the eaves get baffles before any loose fill arrives.
Inside a century home we lay planks over plaster ceilings, fill tight eaves by hand and stop to show you any knob-and-tube wiring or vermiculite before going further. Whatever we find is written into your estimate in plain words.
Newer homes get exactly the same written detail, usually in a shorter visit.
Drop sheets protect the floors and furniture on the route from the front door to the hatch. The fill is fed through a hose from the machine outside, and the vacuum comes out before we pack up.
Depth gauges are stapled up before new material arrives. At the finish you can see each gauge for yourself, and the invoice records the final R-value, the same number any rebate form will want.

Every job below begins with the same free attic check.

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 jobMention when the house was built and which rooms run cold, and we will arrive prepared. Our phone line is +1 (289) 210-8354.
