CUPERTINO PLUMBING did a really good job for us. This was our first time using their services. A friend of mine referred me to them. I called to have a valve to the toilet fixed. The technician, Ron, was prompt, polite and professional. He was a pleasure to work with. He was able to quickly and efficiently find out what the problem was with his assessment. He took the time to explain his findings from the assessment to us and tell us what he would need to do to fix it. He also took the time to answer our questions. He was respectful of our home and very courteous. I would absolutely use CUPERTINO PLUMBING again!
