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 Drain Repair

My bathroom was clogged and flooded. We hired guys from our insurance but no help.Costello’s guy not only cleared the drainage but slso identified and provided solution to leakage in our drainage pipe with minimal charges. They have to get down to my crawl space and replace the old p-tapes and leakage area to avoid further clogging. They even explained us exactly where the clogging was and the future replacement required. I am very satisfied with their work. Not to mention they are very patient with customers and very confident.

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.
