“Airtight Exteriors was excellent from beginning to end. I had at least three contractors come out to speak with me and I chose Airtight Exteriors because of their knowledge, the trust I had in them, and the price. Mike always had time to work with us on deciding what we wanted and needed, along with any questions we had. The cost was VERY reasonable. Miguel and Olga put in our windows with great care. They really knew what was required for proper installation, insulation, etc. And I have never seen anyone work SO HARD and carefully! They were here on time every day and worked long hours. They remained positive and never minded an interruption when my husband and I had questions. Nothing short of amazing for the whole team!! Best experience I’ve had with a home improvement company! I highly recommend them!” – Deborah S.
