The quality of the windows and doors is exceptional. The installation was done on time and with total professional workmanship. I have recommended Castle Windows to everyone who will listen. One of my friends has already bought some windows and is also satisfied with the windows and workmanship—A+.
Castle did a great job installing our new steel front entry door. It looks beautiful, and the installers were punctual, friendly, and efficient. We are totally happy with our decision to go with Castle—A+.
My whole experience with Castle Windows was great. The sales rep was knowledgeable about their product. The installers were polite, worked through the rain to install the windows, and did an excellent job cleaning up.
Outstanding job. I am very pleased with this purchase—A+.
Couldn't be happier. Thanks for a great experience.
Professionalism and a job well done!
Castle Windows did everything they said they would do. From the time we meet to discuss until the time the job was completed. Excellent service.
Overall, very good experience. Only issue was a few small leaks when it rained really hard. I believe I fixed the problem with a little additional caulk.
The windows keep our house cooler in the summer and warmer in the winter. There is no air escaping or coming in the bottom of the windows. They are easy to clean and open. The slider door provides great light in our kitchen. Really enjoy them!
We are extremely impressed. We were very pleased with every aspect of this installation.
