Dura Seal Ltd.

What Dura Seal Ltd. does

Dura Seal Ltd. is a privately held specialty construction firm founded in 1989 and headquartered in Port Coquitlam, British Columbia. The company operates as a General Contractor and Construction Manager focused exclusively on the renewal, restoration, and repair of existing buildings, with core disciplines centered on Building Envelope and Waterproofing. The building envelope practice spans glazing, curtain wall, fenestration (windows and doors), roofing and sheet metal, cladding, insulation, panels, and caulking/gaskets/sealants, while the waterproofing practice covers podium slabs, foundations, parking decks, bridges, pools, balconies, decks, membranes and coatings, and structural/joint injections.

The company delivers project work through direct engagement and referrals from engineering and architectural consultants, serving strata councils, apartment building owners and property managers, BC Housing, institutional clients, and commercial building owners across Western Canada. Beyond core construction execution, Dura Seal offers Discovery and Exploration assessments, Class D budgeting, property maintenance and emergency repairs, and Construction Project Financing facilitation, positioning itself as a full-lifecycle partner from pre-project advisory through completion.

Revenue is generated primarily through project-based contracts (one-time project execution for general contracting) and professional services fees (construction management, maintenance, discovery/exploration, budgeting, financing assistance). Pricing is quote-driven based on project scope and is not publicly disclosed. The company employs 23 people, reports hundreds of completed projects over 35 years, and operates from a single Western Canada office with no subsidiaries, no disclosed institutional investment, and no public listing.
