Paul Chou is an excellent salesman! He came to our home and was very knowledgeable and explanatory with necessary details. We are absolutely confident that the job will be done correctly! Thanks Paul!

We added a sunroom to our home and Champion did a great job! Brian and James worked in the bitter cold the first week of installation. They were the most pleasant workmen I have ever met! They were kind and very easy to work with. The sunroom is beautiful. Many people have commented that it looks like it has always been a part of the house! Great job!

My experience with Champion Windows started very frustrating — it was extremely hard to schedule an appointment, I waited months, and the first technician arrived unprepared and unable to fix anything.

However, everything changed during the final visit. Ryan Wilson and Joseph Koihler were incredibly professional, efficient, and knowledgeable. They fixed the problem quickly and perfectly.

They truly restored my faith in professionalism. Thank you!

I’m in shock ! The whole process was fast , easy & not stressful at all. My windows were in stock & had me scheduled to install & installation was fast! ( 4 1/2weeks ) .But after the installation, I’m so happy with my choice , going with Champion . I’m OCD ! The crew showed up & was very pleasant, respectful towards my property inside and outside. They paid attention to the smallest details to make sure the windows looked amazing! I couldn’t be happier & I most definitely will be a retuning customer!

You guys are great!! From my first contact with Doug to Brian, Dave and the electrician, everything was great. Prompt, friendly staying on task was appreciated. I also appreciate everyone giving me the opportunity to pop my head out to ask questions as the construction was being done, My deck is beautiful!! I’m
Looking forward to enjoying many hours out side this summer relaxing under this beautiful cover. Thank you all for a job well done!!
