Why it costs less (and why there's no catch)

Other companies' prices hide costs that insulate nothing: commissions, sales visits, old machines. We took them out. The difference is your discount.

The most powerful machines on the market new machines

New, high-capacity equipment: an attic gets done in a fraction of the time. Fewer hours on your job = a lower bill, and more even insulation.

Materials bought by the truckload volume pricing

We buy our insulation by the full truckload, for hundreds of jobs at a time. You pay the volume price, not the single-bag price.

How does Isolation à Rabais work?

Enter your address, we calculate your price and your grants instantly, and you get your quote by text. If the price works for you, you accept it and book your appointment online. An installer confirms the measurements on-site, free of charge, before starting. No salesperson, no pressure.

Why are your prices lower?

No commissioned salespeople, everything happens online, and our installers work directly for us. We cut the needless costs and pass the savings on to you, without ever cutting back on quality or guarantees. It costs less because we're more efficient, not because we cut corners.

Is the online price the final price?

Yes. An installer confirms the measurements on-site, free of charge, before starting. If anything is off, we tell you before the work, with no obligation. The confirmed price = the price. And it's guaranteed: we beat any comparable written quote.

Is the work eligible for grants?

For most of our customers, yes (Hydro-Québec's LogisVert, Rénoclimat), up to $1,500. We check your eligibility and take care of all the paperwork for you.

What insulation do you use?

Depending on your needs: blown-in fiberglass, cellulose or spray foam (polyurethane). All are certified high-performance materials, R-51 in the attic. The tool recommends the right choice, and our team confirms it.

How long does the work take?

Installation is scheduled instantly, usually within 24 to 48 h. A typical attic usually takes 2 to 4 hours.

Is the quote free?

Yes, 100% free with no commitment. You're never bound to the price until you've accepted it.

Do you still come on-site?

Yes. An installer comes out to confirm the measurements and validate your project free of charge, right before the work. That's exactly when we take your home's particulars into account (especially in older homes).

Which areas do you serve?

Everywhere in Quebec: Québec City, Lévis, Montréal, Laval, Longueuil, Trois-Rivières, Sherbrooke, Gatineau, Saguenay and surrounding areas.
