Attic insulation replacement puts the attic back together after the old fill comes out. While the joists are bare, leaks around wiring, plumbing and ceiling boxes are sealed, eave baffles are fitted, and fresh loose fill is added until it reaches R-50 or R-60, which matches Ontario's new-home standard.
Insurance covers every replacement job we do. Most people book the removal and the replacement together, so the attic is empty for as short a time as possible.
Houses built decades ago were insulated to the standard of their day, which was far below what a new house gets now. About two thirds of London homes were built in 1990 or earlier, and many of their attics hold only a few inches of old fill.
Ontario's building code now calls for about R-50 to R-60 in an attic ceiling. Blowing new insulation to that depth makes the upstairs warmer in winter and cooler in summer.
Old attics often have deep piles in the middle and almost nothing at the edges, where the roof comes down low. Those thin edges are where upstairs rooms lose the most heat and where frost forms on the roofing nails in winter.
After the insulation removal, new fill is blown to an even depth across the whole attic, with depth markers stapled to the joists so anyone can check it later. The quote states the target depth, and the photos show the markers.
Heated air escapes upward through gaps at wiring holes, vent stacks, recessed lights, the chimney and the hatch. It carries warmth and moisture with it, which is a big reason attics collect frost and roofs grow ice dams.
With the old fill gone, every one of those openings is easy to see. Foam, caulk and sealed covers close them up before any new insulation is blown. Once the attic is full again, most of them are out of reach.
An attic needs air to move in at the soffits and out at the roof vents. Old insulation is often packed right into the eaves, which blocks that air and keeps the roof warm and damp.
We fit baffles between the rafters at the eaves so the insulation cannot block the vents again. In a city on the edge of the Lake Huron snowbelt, good airflow and a sealed ceiling are the best defence against ice dams. If an ice dam has already soaked the old fill, see wet, mouldy and smoke-damaged insulation removal.
BetterHomes London, a City of London program, offers low-interest loans for home energy upgrades, including insulation. The loan is repaid on the property tax bill and stays with the house, and it is available while the funds last.
Ontario's Home Renovation Savings program offers an attic rebate when the whole attic reaches R-50 and the work is done by a contractor registered with the program. It is scheduled to wrap up on November 30, 2026. Rules change and removal may not be an eligible cost, so check the current terms before you count on any program.
Call +1 (226) 400-3320 for a free visit. We will quote the insulation removal and the attic insulation replacement together, with the R-value and depth written down. Our remaining services are listed on the home page.
Droppings, water and thin coverage often turn up in the same attic, so one visit can price several of these at once.
Attic insulation removal clears out insulation that has flattened, gone dirty or stopped holding heat. A vacuum machine parked outside pulls loose fill through a hose into large bags, and batts are rolled up and bagged by hand, leaving bare joists that are ready to be checked, sealed and filled again.

Blown-in insulation removal clears away old cellulose and fibreglass loose fill that has sunk, compacted or been spoiled by leaks or animals. A long hose draws the fill from between the joists into big bags standing outside, so nothing is carried through the house and the attic finishes empty.

Attic cleaning and decontamination removes droppings, nesting and soiled insulation left by mice, squirrels, raccoons and bats. The old fill is wetted or treated and taken out with respirators on and the exhaust outside, and the empty attic is then disinfected and treated for odour before anything new goes in.

Wet, mouldy and smoke-damaged insulation removal deals with fill spoiled by roof leaks, ice dams, a bath fan that exhausts into the attic space, or a fire. The damage is photographed for any insurance claim, the ruined material comes out, and the roof boards are left open to dry and be checked.

Vermiculite insulation removal is a job for trained asbestos abatement workers under Ontario rules. We spot the pebbly grey-brown fill, stop work in the attic, arrange a test through a proper lab, coordinate the abatement contractor if the test is positive, and re-insulate after the air clearance.

Pre-sale and home inspection insulation removal handles attic problems that surface during a house sale, such as droppings, soaked insulation or possible vermiculite. Buyers, sellers, agents and inspectors receive a quick written price, then a set of before and after pictures they can pass along.
View Pre-Sale and Home Inspection Insulation RemovalWe climb into the attic, measure it and put the price in writing. Nothing is owed for the visit, and saying no costs nothing.
Describe the attic and anything you have noticed, such as droppings, a smell, water stains or thin insulation. Your name and phone number are all the form needs. If you would rather talk it over, you can call us at +1 (226) 400-3320.
