We are very happy with our choice to use Centennial Windows and doors. We had all the windows in our home replace and our patio door. The salesmen was knowledgeable and their install team was great. they had to make 2 trips to complete the install (do to an unforeseen issue with our house) but they resolved the problem on their end and continued to the install. warranty work is only a phone call away and they are prompt with replying. we even got a discount because the patio door was less expensive than quoted! we are looking forward to working with them again in the future. highly recommend price is what it is for a quality product. you get what you pay for, we can honestly say we have seen a noticeable decrease in heating cost with new windows installed
