"The windows were pricy but the quality of the windows justifies the price. The crew that installed the windows were wonderful to deal with. They cleaned up after themselves. The project manager was very understanding when I needed to change the schedule due to weather. They accommodated to my schedule changes for installation. They were very professional"

"Zavza Seal is an excellent business! We had a leak in our basement which was attributed to a problem with the foundation. The project manager responded promptly, clearly outlined the specifics of the problem as well as the plan for the repair. He patiently answered all of our questions and concerns. The estimate was fair and reasonable. The crew also arrived promptly and went above and beyond to assure the job is well done. We are extremely satisfied with the job. Zavza Seal is truly an outstanding group of professionals that I highly recommend."

"Overall excellent. My only quibble is that the screen over the window had holes but it was replaced within a week. I would use them again if I need another egress window. Note, these windows are primarily to let people out. If a fireman, or anybody else, have to get in they still have to break the glass."
