I wanted to take this opportunity to thank you and your team for doing such a great work with windows at my house.
They were professional.They replaced the window in a very clean manner.There is not a single trace of old window or any holes!! Excellent work done.I m going to recommend your windows to people in my contacts.
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!

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.
