We are thoroughly pleased with our windows from Design Windows & Doors, Inc.; the worker/employees are all are professional, caring and concerned. We can't believe the difference in our home since the windows were installed. Our home is brighter and appears to be more open. Great investment!!! Many companies gave us estimates not one could compare to this dealer. Yes, we highly recommend this company.

We had 14 new windows installed last week. The quote was under what we had budgeted for and our installers, Danny and Ed did an awesome job. It has made such a difference in our home. Outside noise has been reduced, the house stays cooler during the day and the overall appearance is wonderful. We have had many neighbor stop by and comment on them. Would recommend Hometime Windows & Doors to everyone.

Excellent job from start to finish. Everything was done as promised and on time. Our new sliding doors and windows look fantastic. The crew that did the install were great to work, very professional and friendly. We highly recommend JR Windows and Doors
