I got multiple bids to replace aluminum windows in my Pleasant Hill home with retrofit vinyl windows. Bestoff Windows was $200 dollars more expensive than the cheapest bid, but I chose them because of their reputation and good reviews...
This was the best choice, one of the workers even discovered dry rot inside of the frame of a sliding door and took care of it for free. Awesome!
I recommend this company to anyone looking for replacement windows in the east bay.
Pros: Got the cheapest estimate and the job was QUALITY
