We moved into our present home 3 years ago. The original house was built in 1968. Obviously the quality of the original windows and doors was not even close to the insulation and energy efficiency of today's market products. We decided to take advantage of the Ontario GREEN-ON program and have most of the windows in our house upgraded to the required specifications of the program. Simpson Windows and Doors gave us a very competitive quote and decided to contract their products and services. They did a great job removing our old windows and installing eight new windows in one day. The installation techs were very knowledgeable and highly competent. Our Sales Rep, Gary Hayden, was also very knowledgeable about the available products, the Green On Program, and the required service issues to be aware of when upgrading older home windows. We would highly recommend this company for anyone investing in an window upgrade for their home or business.
