Water Heater Installation or Replacement

We didn't have heat or hot water for 2 days. After my husband trying and failing on finding the issue, and PG&E declaring it wasn't an emergency and that their next appointment is in a week (not gonna happen with 2 kids) we looked through Thumbtack and discovered Costello's Plumbing. Within an hour of messaging them through the app, Miguel showed up! I was blown away by the responsiveness and punctuality. Miguel was professional, detailed and very informative, walking us through all the things that needed fixing. He even caught a water leak that was just starting. We ended up replacing the entire tank and he even waived some fees. Definitely will recommend them next time anyone has plumbing issues!!!!

Plumbing Pipe Repair

We had a leak in our main water line, so needed quick response. Costellos responded immediately, came to check it out same afternoon, and proposed two solutions (cheaper, ‘stopgap’ solution or more expensive but longer term solution). We went with the longer term solution to avoid this happening again. The team that came was very transparent on the solutions, costs, and time to repair. They came and completed the repair next day, as promised. They were great to work with, kept us updated and while having to put in a new line, were careful to put back dirt, lawn, etc. in as close to as possible as it was. We were very impressed. I should also note that we had a different plumber come by to look, as well, and they only gave us the ‘stopgap’ option that Costellos did, but initially at double the price. So glad we went with Costellos.

Plumbing Pipe Repair

Victor was very knowledgeable an went the extra mile sealing the connectors with plumbing tape to assure no future leaks. He also informed about water pressure and my water heater being drained for longevity of use.

Water Heater Installation or Replacement

My water heater had a leak and needed to be replaced quickly. Costello Plumbing was able to fit me into their schedule and replace the water heater the next morning. They also advised me in advance based on pictures I sent them of my old water heater of any changes that needed to made for code compliance and the cost. They are very professional and try their best to give you an accurate quote by phone based on the information provided to them so there are no surprises. The crew did a great job!

Water Heater Repair or Maintenance

Water heater replacement completed. Came out to repair it and was not successful. Didn’t try to sell me a new one. However, they found other problems after they had it repaired and recommended a new one which I agreed. The price was higher than expected but they do good work. Thank you. Highly recommended.
