We just had 15 of our builders windowpanes replaced by Simon & Sons. I could not have been more impressed with the companys representative, Paul, and the work he performed. Paul was professional, courteous, and extremely knowledgeable about the industry. The employees a company has working for them reflects highly on its ownership. This company is obviously well run by its owners. Great job and competitively priced.

We purchased a new sliding door from Simon & Sons. The installation was done by their own crew (not subcontracted out). They were very professional and cleaned up afterward perfectly. We plan to have them replace our other sliding door and front door soon! Best of all, they kept us apprised of the order status frequently by emails and came when they said they would arrive to install.

Simon and Sons was an absolute pleasure to work with. When we were just gathering information, Evan was wonderful to deal with and very knowledgeable and responsive (he was also great after we ordered). Derrick was helpful and made great recommendations during the measuring portion. Finally, the crew was fantastic to spend two days with. Theyre great guys and are clearly very experienced. Colin even fixed an issue I had with an existing window I was keeping and bought me an ice cream cone when the ice cream truck stopped at my house. Vitas does fantastic trim work - There was an issue where

6 stars if I could! Had a crack in my window due to weather changes, Colin came inspected my window
measured it, ordered it and repaired it in a quick and timely manner. He was very professional, respectful, and wasnt afraid to answer any questions if I had any. Reasonable price for the repair too! I would gladly have them come back and do any window and door work anytime. Highly recommend them!
