Isolation à Rabais

Old attic insulation removal

Clean removal of old insulation, when adding on top is no longer enough.

Why remove the old insulation?

You can't always just "add on top." When the existing insulation is settled, soiled or damp, extraction — the complete removal of the old insulation — is the step that ensures your new insulation will actually reach its rated performance (R-50 to R-60).

Our team and equipment, ready to work at a customer's home.

When extraction is necessary

Settled insulation that has lost most of its insulating value.
Contamination by rodents, mould or water infiltration.
Vermiculite to be removed safely (see our dedicated page).
Major renovation of the attic or correction of ventilation.
Odours or air-quality problems coming from the attic.

Add or remove? We'll tell you honestly

In many cases, adding thickness over healthy, dry insulation is enough and more economical. Extraction is only needed when the existing insulation is compromised. Our job is to tell you the truth: we don't charge for an unnecessary extraction.

Assessment of the real condition of the insulation in place.
Clean extraction by industrial vacuum, with no mess in the home.
