It looks like we found our local plumbing superheroes! Quick response, repairs, and future project advice - they're like the Avengers of home maintenance. Exciting to have reliable folks nearby!

Got the handle of my (very old) water main valve broken that was on the off position, so no water going in the house. I used Yelp project and a few plumbers contacted me. Most seem pretty qualified. I ended up using Costellos as they were able to do the fix the same day with reasonable price. The team is very professional and efficient with their work. Word was done very well. Will use them again for my future plumbing needs.

Just had our water heater done by Costello's Plumbing. I was a pleasure dealing with these guys. Miguel came in and scanned the work that needs to done throughly. Explained why it needs to done. At the end of the job, he explained how to work the heater(igniting pilot, flushing etc.). Ask for Miguel. He will not disappoint. So friendly and accommodating too. Good job!

Our 18 year old hot water heater stopped working last weekend. Costello's was the first plumber we called and Gary the owner answered and started working with us immediately. He had to do some leg work (calling, driving) to get us the new hot water heater so he could replace ours the same day. He kept us informed on what was happening. He was responsive, polite, and did great work. I highly recommend.

I highly recommend this company and the gentleman that helped me out! Absolutely fabulous. I was stranded with a corroded p-trap in my kitchen sink. He came over and problem solved until he fixed it, and there were quite a few things that went sideways during that experience. I was not charged through the nose at all!!! It was incredibly reasonable and I am very pleased with the service and will most definitely use this company again.

We reached out to Costello about a potential leak under our foundation on a Monday. They answered our call right away, no voicemail or phone tag and scheduled a visit on Tuesday . Came out and looked and advised on hot water usage in the meantime as well as scheduled leak detection for next day. Once they received the report, they called the and scheduled repair for Friday morning. They showed up on time, did all the work in one day (I expected a few days) including protecting the area, covering vents, covering surrounding floors, plastic around their work area to contain dust from jackhammers and finished the work, cleaned up, and left the area clean when they went home. Amazing how quick and easy it was. Price was fair and reasonable too. Thank you Costello. Keeping this one in my contacts!!

Willie was my technician who unclogged my drain today. He was communicative, reliable and professional. I know my drain is not the easiest, but he kept trying and trying until it's working. He came out the next day very quickly as promised. Everything was smooth and peace in mind. I highly recommend this company and their technicians.
