Peter and his staff did an excellent job of design and installation of windows on our third level and now second level Oak Park Home in Oakville. Absolutely incredible windows and installation.

Please pass my appreciation to the team and your management- I can have this officially stated.
I want to wish you Happy Holidays and all the best for you and for your family in new year!
Our thanks to your company for the prompt & professional job that was done on our home. Your installers (Ken &David) were great at explaining each phase of the work & answering all of our questions. It is obvious that they take pride in the work that they do (two thumbs up guys). Our home has been transformed & we are very happy with the look.
I would recommend Custom Window Designs to anyone thinking about purchasing windows. From picking out the right windows at an affordable price to the installation CW provided first class service. Custom Windows have reduced my homes heating/air conditioning bills by 20%. I have tested the post sale customer service as my pet destroyed one of the screens, and the screen was replaced within two days. Thanks to Danny and team for a job well done!
