Customer satisfaction

We are so impressed and happy with Renewal by Andersen through Asher Lasting Exteriors. Mick and Brad installed our first half of our home’s windows back on July 17, 2019 and did a marvelous job. Yesterday, December 6, 2019 we replaced the remaining windows of our home. Due to how satisfied we were with Mick and Brad back in July we requested that they were to install this set of windows. Asher Lasting Exteriors had split up Mick and Brad so they honored our request by sending both crews for this final project. We had the pleasure of having both Mick and Matt along with Brad and Holt install these last windows. All four of these wonderful installers, treated us, our home and the installation of these final windows with the up most respect and efficiency. Mick, Matt, Brad and Holt not only deserve a 5 star rating, they deserve a 10 star rating along with Renewal by Andersen and Asher Lasting Exteriors. Duane J. and Marie E. Bauer
