How It Works
Kasa Demolition simplifies every step: from initial contact to receiving a clear, detailed quote, with no obligation.
Contact Kasa Demolition by phone at (514) 812-8763, by email or through the online form. Briefly describe your project: type of demolition, the space involved and its location in Montreal.
Once contact is established, Kasa Demolition schedules the on-site assessment at a time that works for you.
A Kasa Demolition expert visits the site to assess the space and identify technical constraints (load-bearing walls, utilities, potential presence of asbestos).
They also determine the municipal permits required for your borough. This visit is included in the quote process, at no charge.
Once the assessment is complete, Kasa Demolition prepares the detailed quote.
You receive a written quote detailing every line item: labour, demolition method, debris removal and disposal, permits, and applicable CNESST standards.
No hidden fees. No obligation to purchase. The delivery timeline for the quote is confirmed during the visit.
Service Area
Available 7 days a week, 8 AM to 10 PM, in every borough of Montreal, Laval, Longueuil and South Shore municipalities.
