Hired on Thumbtack
Met with Alex. Very nice and enthusiastic about my project. Gave me great ideas during the walk through estimate. I think he was even more excited about my remodel than I was! It came down to Cornejos Builders and a family friend contractor. Went with the family friend. If it wasn’t for that connection, I would have hired Alex in a heart beat. Hopefully we can work with each other on my next project.
Details: Full remodel of bathroom • Update style • Master bath • Home

Called Cornejos Builders after seeing their beautiful work on Tik Tok. Spoke to the owner regarding an ADU project. Alex always returned my calls, explained throughly how the project would be completed. Love how his company is an all in one stop. They definitely handle everything from getting permits, architect, plumbing, electrical etc. Turn key ready, his prices are very reasonable and is willing to work around your budget. Alex was very understanding when I explained why I had to put a hold on the the project. He definitely treats his customers like family.

Overall, my wife and I are happy with our ADU.I first need to point out CB builders strong points: Alexsander and his Father Pancho are knowledgeable and dependable. Their crew, Carlos and Andres are courteous and hardworking. Hugo, the tile layer , takes pride is his work and it was a joy to watch him work. The plumbers used top materials and did professional work. The cabinet and countertop guy are professionals. Cesar, the electrician is knowledgeable and clean.Now the negative. First, their drywall crew was sloppy. I came in on numerous occasions to correct their work Secondly, cleaning up was a bit of an issue for them. During the four month construction, CB Builders only picked up the trash pile twice. On numerous occasions, I cleaned up after them. The third issue was the one sided contract I signed. Ninety-nine percent of it is written to favor CB builders. I strongly recommended you read it carefully or hire an attorney to explain it to you. This will help you avoid misunderstandings as the project progresses. The fourth issue, and this is important, ask your architect to draw or directly annotate the details regarding the sewer, water, and gas hook up on the plans. My architect did not, and this was a point of contention. I resolved this by hiring a different plumber to finish the hook ups at a 70% savings compared to the CB builders estimated change order. My sons and I, did the asphalt removal, trenching, backfilling, and the concrete driveway repair. It was a major headache and backache for me. However, in the end we are happy with the ADU and CB builder workmanship on the project.
