What Others Say About Us

View more testimonials here

Hardy Window Company was one of three companies that provided me with a window replacement estimate. Casey Hardy was our sales representative and his quote was considerably less than the other two companies. From quote to job completion, it took less than one month. This company was professional, prompt, efficient, clean, and took great care to protect my home while they worked. They replaced 29 windows and it only took a day and a half. The first day the crew arrived by 7:45 a.m. and by 4:00 p.m., they had all of the new windows installed. On day two, they trimmed all of the windows, cleaned them, inspected them, and made sure I knew how to operate them.

I was very impressed with Hardy Window Company and would highly recommend this company to anyone interested in window replacement.

My wife and I went to Hardy’s showroom where the selection of the products they carried was terrific. We met with one of Hardy’s sales reps who later came down to our residence to look at the scope of the work. The sales rep arrived on time and gave an estimate for the cost of the job broken down by labor and material. The sales rep made sure we had a written contract describing exactly what to expect from the crew.

The day of the installation the two crew members arrived as scheduled and the supervisor went over what they were planning on getting done. The removal and installation project went as planned without any issues. The crew did a professional job as far as the installation of the new windows were concerned and they left the job site “spotless,” after they finished for the day.
