  • review rating 5  We can't say enough about how wonderful the experience with Julian and his team was from beginning to end. Communication was so clear about our options. We never felt pressure. And the best part of course was the quality of the installation. The crew were kind, hard working, efficient, clea, and professional in every other way! Thanks!

  • review rating 5  All I can say is Wow! Julian's crew arrived right on time - on the hottest, most humid day of the year - and installed my new old door. The guys were amazing - very professional, polite and clean. Their attention to detail was impressive and I couldn't be more pleased. Would wholeheartedly recommend, and definitely use them again!

  • review rating 5  Julian and his team did a great job from start to finish. He talks straight and gives me full details and disclosure from the get go. His team showed up on time, did their job well and cleaned up after. The guys were all very friendly and shared tips on window frame painting, glass cleaning and even beer choices :). What impressed me most was Julian's honesty and integrity. He had promised to make best efforts to make the new windows fit my old, existing custom-made blinds. When it turned out that they won't fit even after cutting (at no cost to me), Julian paid for my new blinds! I highly recommend Comfort Windows!
