John and Brandon did an excellent job at replacing my outer doors. They did a very professional job in not ideal weather conditions. There work area was cleaner then when they started and the doors work great. I am very happy with my new doors from Asher.

The crew of Mick and Taip arrived on one of the coldest days at the end of February. The cold weather did not deter them from getting the job done. They quickly reviewed the project, told us what to expect and began work. They put down drop cloths to protect our carpeting and flooring. They removed one window at a time and replaced them as quickly as they could to keep the cold air out as much as possible. Chad joined the crew on the second day to help with the outside work on the windows. It took the crew 1 1/2 days to replace 5 large windows. They will return at a later day to replace one more window.
They were very respectful, professional, and answered all our questions. They demonstrated how to operate the new windows. Each day they cleaned up after themselves and took the old windows with them to dispose of them.
The windows are beautiful. Although the replacement windows are the same size as the old ones, they seem much larger. Even after only one day, we can tell they are brighter, quieter, and have eliminated the cold drafts of the old ones. Needless to say we are very pleased! We would recommend Asher, Mick, Taip, and Chad to our family and friends.
