Frequently Asked Questions

The biggest factors are the size of the attic and how deep the old insulation is. The type of fill matters, and so does the access, such as a small hatch, low headroom or a long hose run. Droppings, mould or water damage add cleaning time, which raises the price per square foot.

It should not be messy inside the house. The vacuum and the bags stay outside, only the hose comes in, and the floor from the door to the hatch is covered. The hatch opening is sealed with plastic while the work goes on.

For a standard job, the family can usually stay home. Keep children and pets out of the hallway or room under the hatch until the job is done. If vermiculite with asbestos is found, the abatement contractor will say what is needed, and that may include leaving the house.

Look for a musty or animal smell upstairs, stains on the ceiling, droppings near the hatch, or insulation that looks flat and grey. High heating bills and ice dams along the eaves can point to the same problem. We confirm it with a visit and photos.

It can. The work is done from inside the attic with a vacuum hose, so the ceilings below are not touched. The hose goes up through the hatch, and the fill is pulled out to bags outside the house.

We stop work and arrange a test at a proper lab. If the result shows asbestos, removal has to be done by a trained asbestos abatement contractor, which we coordinate. We come back to re-insulate after the air clearance is done.

A small amount on a shelf is fine to clean with the wet method public health recommends. An attic full of droppings is a bigger job, because the insulation holds dust that should not be breathed in. A removal crew dampens the material, works in respirators and vents the vacuum outdoors.

It depends on the policy and the cause. Sudden damage from a fire or a burst pipe is often covered, while slow leaks and animal damage often are not. We provide photos and a written quote for the claim, but only the insurer can decide what is covered.

Ontario's Home Renovation Savings program has given money back on attic insulation that reaches R-50 when an enrolled contractor installs it. It is set to finish in November 2026 and could close sooner if its funds run out. The current rules are on its website, and removal may not count toward the eligible cost.

Clean insulation at full depth, with the air leaks sealed underneath, keeps more heat in the house. The savings vary with how poor the old insulation was and how the house is heated. Older houses with thin or damaged fill usually see the biggest change.

We provide insulation removal across St. Thomas and Elgin County, including Port Stanley, Belmont, Sparta, Union, Lynhurst, Shedden, Fingal, Talbotville, Iona Station, Aylmer and Dutton. If your town is not on the list, call and ask.

Trailer-mounted insulation removal vacuum with a big collection bag in a driveway and a hose running to the house

Attic Insulation Removal

Attic insulation removal takes every layer of old batts and loose fill down to the bare joists. A trailer vacuum in the driveway pulls the loose material out through a long hose, batts are bagged by hand, and the attic floor is swept clean before any new insulation is added.

Blown-In Insulation Removal

Blown-in insulation removal clears settled cellulose and loose fibreglass out of an attic through a wide vacuum hose. The fill rides the hose down to collection bags parked beside the driveway, which keeps it off the stairs, the carpets and the furniture in the rooms under the attic.

Attic Cleaning and Decontamination

Attic cleaning begins by stripping out insulation that mice, raccoons, squirrels or bats have fouled with droppings and urine. The soiled fill is dampened, bagged and hauled off, and then the joists and roof boards are sanitized and deodorized so clean insulation has a fresh surface to sit on.

Vermiculite Insulation Removal

Vermiculite in an attic is left alone until a lab result comes back, because this fill may contain asbestos. We halt the job and have a sample analyzed. When asbestos is confirmed, we coordinate a trained asbestos abatement contractor to take it out, and we re-insulate after the air clearance.

Attic Insulation Replacement

Attic insulation replacement follows the removal while the attic floor is still bare. Gaps around wires and pipes get sealed, baffles hold the soffit vents open, and fresh loose fill is blown in to R-50 or R-60, the depth Ontario's code packages set for new homes.
