Is It Time to Clear Out Your Attic Insulation?
In London’s long, cold winters, attic insulation eventually stops pulling its weight, and removal is worth considering once you notice signs like these:
Rising heating bills as settled or thin insulation lets warm air slip out through the attic all winter
Ice damming and attic frost that leave the insulation damp, matted, or streaked with mould
Mice and squirrels that nest in Southwestern Ontario attics and leave droppings and torn fibre behind
Musty odours or allergy flare-ups that point to aging, moisture-laden material
Renovations or additions that call for opening up ceilings or attic space
Older knob-and-tube wiring in century homes that must be cleared before electrical upgrades
A Superior
Warmer Winters, Smaller Bills
Clean removal comes down to the right equipment. We stage our vacuum system outside the house and draw the old material straight into a sealed container, so airborne dust and fibre never drift into your living space. Through a London winter, that contained approach protects your indoor air while we clear the attic from end to end.
These capabilities define the insulation type:
The right gear for the job: A complete removal often calls for commercial vacuums, protective equipment, and treatment products to handle damp or contaminated material safely.
Protects your household: Disturbed old insulation can release fine particles, so proper containment and protective gear matter for everyone under your roof through the long winter.
London's Easy 5-Step
Insulation Removal Process
Free Home Energy Assessment
Our Koala Insulation team looks closely at how your home holds heat through the deep-freeze months and where the attic is quietly costing you comfort.
- Attic & Home Walk-ThroughEvery project opens with a careful look through your attic and home. We note the type and depth of insulation, check for frost, condensation, and ice-dam damage, and watch for rodent activity, then assess ventilation, air-sealing gaps, and access so the removal is planned to run cleanly and safely from the start.
Koala Difference: We dig past a quick glance to find the air leaks, frost, and ventilation issues behind London’s biggest winter heat loss.
- Prep & ContainmentNext we set up the work zone, shielding access points and laying protective coverings from the attic hatch out to the truck. Where the layout calls for it, we put up barriers and run negative-air equipment so dust and loose fibre stay well clear of your finished rooms while the job is underway.
Koala Difference: We box in the mess before it starts, so nothing drifts into your finished London rooms.
- Old Insulation ExtractionOur crew pulls the aging insulation with professional vacuum equipment, working methodically across the attic floor and into eaves, corners, and tight cavities. Settled, frost-damaged, or contaminated material is drawn directly into a sealed collection unit staged outside, so nothing compromised is left hiding above your ceilings.
Koala Difference: Commercial equipment and a controlled process hold back the dust and protect your comfort while we work.
- HEPA Detailing & Treatment
Once the bulk material is out, we run HEPA-filtered vacuums across the attic floor and framing to lift the fine dust and fragments larger equipment leaves behind. If we found pests, droppings, or moisture, we can follow with a disinfectant or antimicrobial treatment and a deodorizing pass to clear that stale, musty attic odour.
Koala Difference: Detailed HEPA cleanup and targeted treatment hand you an attic that is genuinely clean, not simply emptied.
- Cleanup & Responsible Disposal
From there, the old insulation is bagged, loaded, and hauled off-site for disposal that follows the City of London and Ontario waste guidelines. You are left with a tidy property, and the material is dealt with the right way instead of piling up at the curb or in your own bin.
Koala Difference: Nothing gets dumped in your bin; London insulation waste is removed and handled responsibly.

Xan was great with the assessment, detailing out the issues we had and the process going forwards. He helped us navigate the rebate system and the price point was great as well. Once we had a separate issue dealt with, we were able to book very quickly and his crew were timely and clean!

Great friendly service with Xan and his installers. Had blown in attic insulation added as well as spray foam done. Both trucks well equipped, clean. Took every effort to cover work area and clean up after the job was complete.
Fair pricing and quick service and took the time to explain work thoroughly and provided before and after pictures. Will use his services again on other properties.

Should I remove my old insulation or just add more on top?
If your attic insulation is dry, clean, and undamaged, topping it up toward the R-60 level suited to London’s climate is often the practical choice. Removal makes more sense when the material is matted, mould-stained, frost-damaged, or fouled by rodents, since burying compromised insulation just seals the problem in. A quick attic assessment tells you which path fits your home.
Can old insulation lead to attic frost or ice dams in winter?
It can. When insulation is thin, settled, or paired with weak attic ventilation, heat escapes unevenly and warms the roof deck, which drives the melting and refreezing that forms ice dams and attic frost. Over time that moisture leaves the material damp and mouldy. Clearing it out, then air-sealing and ventilating properly, helps keep the attic cold and dry the way an Ontario winter demands.
How long does an insulation removal project take?
Most residential attic removals wrap up within a day, though the exact timing depends on the size of the attic, how much material comes out, and whether contamination calls for extra cleaning or treatment. After a free on-site assessment, we give you a realistic timeline alongside your quote, so you know what to expect before the crew arrives.
