Left no mess behind & final charge was the same price as they originally quoted. Can't argue with that!

Most offered the same type of products just from different manufacturers. This company had a very reasonable prices which was lower than most of the competition with the same or better warranty and quality of product. They were able to customize the glass for a few of the windows for my situation having artificial turf. But the windows are still California compliant and passed inspection for the permit. The installation was completed in one day. They did a good job cleaning up after the work was completed. I recommended them to a few co workers at the office.

The quoting process was incredibly smooth and it was extremely pleasant to work with them. I had 2 doors installed. I had quoted doors with 5 vendors. Bay King was not the cheapest nor the most expensive, but their level of customer service made it the best value. In the end, their commitment to their customers is well worth the price they quoted. They went the extra mile to help patch up some parts of the wall near the doors. Additionally they also tighten up some parts of the door sweep so for best insulation. The work was prompt and I felt happy that they followed up afterwards. Unfortunately my hardware didn't come in time and when I tried installing it after it didn't quite fit. They were able to set up some time to come address it immediately. Their dedication to their customers is really amazing. They really do stand by their work and go the extra mile to make sure the doors work well. I'm glad I went with them. Overall, I would definitely recommend.
