We started using Comfortglaze last year for a few rooms, and have called them back several time to do more windows in our home. Customer service, communication and onsite jobs have all been smooth sailing and well executed. Each team member that has come to our home has been professional, friendly and has done an awesome job. Well done team. So happy to have partnered with you with our biggest asset. We are not finished yet, so you will see more of us! Thank you!
The Barrett Family.
