Great service and an outstanding company to deal with! I thought it would be much more expensive to fix my windows but Apex did a great job for a reasonable price.


Marcelino and his associate were superbly trained, courteous and thorough in replacing a bay-window frame. They also painted the adjoining doors frames as a courtesy. I had some issues with one of the phone reps but on-site, this was a top-notch job.

Peter Kirstein

Responded on time and made clear what they wanted to do and duration of work. Left no mess to clean
