About Dura Seal

Dura Seal was born of the 'leaky condo crisis' and has grown alongside the Building Sciences Community in Western Canada. We work exclusively on existing buildings and have a track record of hundreds of successful projects delivered in our 35 years in business. Our broad specialty is Building Envelope and Waterproofing, so essentially anything to do with the exterior of a building from the roof to the windows and doors, to the underground parkade or penthouse swimming pool.

Our team comprises highly experienced Project Managers and a Construction team of talented multi-disciplined tradesmen to tackle the most complex and challenging restoration and renewal projects. Our work is specialized; our Team Members are doers; and our work is done right.

When you are looking for specialized know-how and value-added solutions, look to Dura Seal.

Planning a BECA?

Understand your building today. Plan confidently for tomorrow.

A Building Envelope Condition Assessment helps owners and strata councils understand the condition of their building’s exterior, identify repair priorities, and plan for future renewal.

Dura Seal supports your engineering consultant with exploratory openings, site access, and reinstatement, along with practical construction input and preliminary budgeting. Together, we help turn assessment findings into a workable plan for protecting your property.
