We have been in business for over 40 years and, in 1995, we introduced the tubular skylight to British Columbia and other parts of Canada. We have extensive knowledge in skylights and tubular skylights, and have helped to make improvements in the design and performance of the tubular skylight. Today Donnelly Skylights is proud to be one of Velux's Skylight Specialists. This enables us to work closely with Velux in order to maintain a good relationship with our customers. With nearly 18 years of experience in the skylight business we offer to our customers a (5) five-year warranty against any leakage due to improper installation. In addition Donnelly Skylights carries a $3 million commercial liability insurance policy for protection and we are covered by WorkSafe B.C.
