My son broke the glass in patio door and needed to replace it because it's a rental property. After shopping around for patio door replacement, I finally contacting Cambridge Window Homeview Improvements. I think this was the best decision I've made in so far. John and his team did a terrific job. The job was done very professionally and on time. John was very knowledgeable and professional. He explained all pros and cons of our product choices, gave us the best price, was always available on the phone even after we signed the contract, and was present during the installation to ensure the installation was smooth. I am going to highly recommend this company to all my friends and family. Thank you John for your professional work !
