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 fact that they took time to do this, tells me they'd be a great company to work with. Integrity and sincerity goes a long way, and it's not something that can be taught. I'm sure you'd be in good hands with this company.

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

This was a stellar experience from beginning to end!…read more We spoke with Amanda Rodriguez over two different visits and she could not have been friendlier or more knowledgeable. We had tons of questions and decisions about what best matched the original look of the windows from our 1939 house. We finally decided on what windows we wanted replaced and put down a deposit. A second team member came out weeks later to confirm the measurements. And some weeks after that, the installation team of Juan and Erik came out to do the install. (They even started by doing the measurements a third time to make sure everything was correct! And it was.) They had told us that the job might take the whole day, but they carefully removed the old ones, installed the new ones and cleaned up afterward in only about six hours. It was a flawless experience. Everyone we dealt with was extremely kind, warm and knowledgable. And the new windows look stunning - while still matching the look of the almost 90-year old home. We cannot recommend them highly enough!

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.
