Attic Insulation Top-Up To R-60
An attic insulation top-up blows fresh cellulose over the layer already in place and lifts the attic to R-60. For a chilly top floor in an older Orléans house, it is the quickest fix there is.
Details and pricesVermiculite insulation is a light, pebbly loose fill in silver-gold to grey-brown. Some vermiculite insulation sold in Canada before 1990, including the Zonolite brand, came from a mine with natural asbestos in it. Not all of it contains asbestos, and nobody can tell by looking.
That is why a lab test comes first. We do not remove vermiculite insulation.
Vermiculite insulation that stays put poses little risk. The risk comes when it is stirred up by renovations, storage or wiring work. Until the results are back, keep out of the attic and store nothing up there.
If you are not sure what is in the attic, describe it or text us a picture through the hatch opening, and we can say if it looks like vermiculite insulation.
A trained person takes samples and a lab tests them. A negative result means the attic can be handled like any other. A positive result means an asbestos abatement contractor removes the vermiculite insulation under Ontario's asbestos rules.
With the vermiculite insulation gone and the attic cleared, we seal the ceiling and blow in new cellulose attic insulation to R-60.
The first Orléans subdivisions went up in the late 1960s and 1970s, before the Zonolite mine closed in 1990. Most of those attics hold fibreglass or cellulose, but only a test can rule vermiculite insulation out.
Testing and abatement are priced by the firms that do them. Our part is the new fill once the vermiculite insulation is gone, priced like an empty attic at about $1.75 to $3 per square foot at Ontario market rates.
Call (343) 301-5501 before anyone touches vermiculite insulation in the attic, and we will explain the next step. The Orléans Attic Insulation home page lists our other services.
Two of these often go together in Orléans, such as sealing the ceiling and then topping it up.

Cellulose attic insulation is blown in as loose fill and settles into a dense, even layer across the whole attic floor. It reaches the low corners at the eaves where batts often stop short.

Attic insulation removal pulls out old fill that is flattened, dirty or damaged, so the attic can be sealed and refilled properly. It leaves through a sealed vacuum hose and goes away in bags.

Attic air sealing plugs the openings between your living space and the attic above. Heated air rises out through pot lights, wire holes, vent stacks and the hatch, carrying moisture along with it.

Ice dams start when warmth leaking out of the house softens roof snow from underneath and the water freezes again at the cold overhang. Ice dams then hold back more meltwater, which can creep under the shingles and stain the ceiling.

Wet attic insulation holds little heat, and left damp it can feed mould on the roof boards. We find out where the water came from, take out the damaged material, and reinsulate once the wood is dry.

The Ontario attic insulation rebate comes from the Home Renovation Savings program, run across the province by Save on Energy together with Enbridge Gas. Its attic-only stream pays up to $1,250 once a thin attic is brought to R-50, and it does not ask for a home energy assessment first.

Two numbers drive attic insulation cost: how many square feet the attic floor covers and how many inches it needs. You get the going rate when you call and a firm written price after the free check.
