What Our Chula Vista Customers Are Saying

  • ⭐⭐⭐⭐⭐

    Oliver from THA did an amazing job! He was able to diagnose and fix our plumbing issue really quickly. He was polite and friendly, and he was able to walk me through what he found and explained the preventive measures we can take to help avoid future issues. I will definitely be using THA again, and would recommend them to anyone who needs quick support.

    Oliver was fantastic. The best plumber I’ve ever worked with. He is patient, polite, knowledgeable about many contracting specialties, explains things well, and answers questions. He cleans up after his work better than he found the site. If you want to have this kind of plumber in your contacts to share with your friends and family, Oliver at THA is your guy.
