WSIB Insured

We never hire subcontractors and all of our employees at Centennial Windows & Doors are fully covered by WSIB. This protects you and the worker should an accident happen while working at your home. It also helps to ensure that the installers receive proper safety training, carry safety equipment, and use it while on the job. In the event that something happens at your home, we have a minimum of $5 million dollars in liability insurance coverage for our jobsites.
