Bill McIntosh, the owner of Airtight Window and Door, recently installed a new patio door for us. We are very pleased! The work was done very professionally, with lots of attention to detail. The ease and confidence with which Bill completed the work reflects his decades of experience. Bill is very affable and considerate of the needs of the homeowner. Bill was recommended to us by a senior staff member of a major building materials supplier in the area (who himself has decades of experience in window and door replacement). We highly recommend Airtight Window and Door!
I needed a front door completely replaced in our new house. I called airtight window and door, left a message and Bill called me back the next day, we scheduled a time to look at the job, it took a few weeks to get the doors delivered, and job was completed in one day. Bill is thorough and takes pride in his work. I will continue to use him for my future window and door needs.
Bill was fantastic! He was very knowledgeable about the products and he helped me to get the exact door I wanted. The wait time was very reasonable. He was efficient with the install and my place was immaculate afterwards. I can’t recommend him enough!
It was a pleasure working with Bill. We received a very prompt response to our request for a quote. Bill was punctual, professional and exceeded our expectations. The job was done right and we could not be happier. I would highly recommend Bill McIntosh and Air Tight Windows & Doors.
Prompt, professional, clean. Easy to work with, very knowledgeable. The kind of straight shooter you hope for with any job. Have already recommended to others!
