Information
Frequently asked questions
How much does demolition cost in Montreal?
The price depends on the area, the materials, the thickness of the concrete, access and the volume of debris. We prepare a detailed quote after seeing the site.
Do I need a permit to demolish in Montreal?
It depends on the work and the borough. Demolishing a building requires authorization from the borough. We check with you what applies before we start.
What do you do with the debris?
We bring it out, sort it and take it to approved sites. Concrete and metal are recycled whenever possible.
Can pressure washing damage my paving stones?
Not if the pressure and nozzle are right. We clean without digging out the joints or marking the pavers, then polymeric sand or a sealer can be added.
Do you hold an RBQ licence?
Yes. Dahomey Construction holds RBQ licence 5825-5522-01, which you can check in the public registry of the Régie du bâtiment du Québec.
Which areas do you serve?
The whole island of Montreal from our base in Ahuntsic, plus Laval and the West Island (Kirkland, Pointe-Claire, Dollard-des-Ormeaux and Pierrefonds-Roxboro), in English and French.
