    Frequently Asked Questions for Gas Line Installation & Repair in San Jose, CA
    Q: What are clients of Diamond Certified gas line installation and repair companies saying about companies in San Jose, CA?
    A: Verified Allstar Plumbing Customer, 1 of 216
    "They came almost as soon as I called and they resolved what they could and they did something diagnostic that they had to come back for, but at least they got our plumbing working and when they came back, they applied the cost of the emergency response to the work that needed to be done, which ultimately saved us a few hundred dollars. I worked with a plumber named Larry who was really informative and told us what needed to be done and it was just quality service. Their prices were reasonable and they came when we really had a need. Quality service and responsive" - Rebecca R.
