★★★★☆

Thank you Costello Plumbing for being so responsive. I needed the backyard hose valve replaced and you came the next day. The plumber, Miguel, was professional and explained everything he was doing along the way. The repair took less than 45 minutes which was great.

I found this company after 8 pm after on outdoor pipe burst and I had to turn the water off to the house. They called me back before 11 pm and showed up at my home by 9 am It was a big job, completed beautifully. I am grateful. The water is back on in no time really. Miguel was kind, focused and easy to talk with.

Gary was so easy to work with -- he set up a sewer lateral inspection with us and worked around the schedule of the sanitary district inspector to get it done very quickly to help us move forward on a home inspection. Not only that but he showed up early and was all set up for the inspection by the time the inspector arrived on site. It was quick, painless, and his quoted price was comparable to other contractors in the area. We will be calling him back for plumbing repairs as soon as we close. Thank you, Gary!

Made quick work of garbage disposal replacement and fixing a leaky faucet in my home. I called around 11 and they were able to work the same afternoon. Meno was very knowledgeable, polite, and efficient, getting all the work done in about 2 hours including a trip to get parts. He saved me a lot of money and time by repairing the bathroom tub faucet instead of the big job to replace it (which would have required cutting into the tile and the wall). I will call them again if I need a plumber.

I found them on google and they were listed as one of the top 10 plumbers. We wanted to work on a mini project and needed someone who can handle it. They're really responsive and the price they quoted is very reasonable compared to what other companies quoted us for. I'm very satisfied with their work and we would definitely call them if we ever need to.

Gary is a an expert plumber. Very knowledgeable and experienced. I can tell he has seen it all and knows how to fix anything. We originally contacted Gary to help us figure out if we should install a new hot water heater or go tankless. He explained the pros and cons very clearly and helped us make an informed decision.

One month later we were demoing concrete in our backyard and our main water line and sewer pipes were damaged. We called Gary and he came right away to start fixing the damage. Because our pipes were in such poor condition, we decided to replace all of them with new copper pipes. We needed the work done immediately. Gary cleared his schedule and started working on our project. He finished it right away without taking breaks in between workdays.

Gary redid the entire plumbing of my 1922 home, which was a mix of galvanized and old copper. He worked with us in terms of budget and timing the project with our travel needs. He was helpful, efficient, professional, honest and very easy to communicate with. Top quality work at a very reasonable price. I'm planning on working with him in the future.
