Good: Sergey showed up ON TIME and gave me the cheapest estimate. Plus I looked over his list of references and was very impressed.. Other: I had old aluminum windows in my Walnut Creek house which were a drain on my energy bill and looked like a drag from every corner.
They replaced all the windows in my house in one day, now I have beautiful double-pane vinyl windows and have the prettiest house in the neighborhood. Very happy with the work done, doing business was a pleasure.
Thanks Sergey,
Rob.
