Prepare your project in Notre-Dame-de-Grâce (NDG)
When calling about a leak, provide the address, the affected floor and whether water is near electrical equipment. For a plex or condominium, identify who authorizes work and coordinates access. The cause assessment should include flashing and connections, not just the roof directly above the stain.
