      Very quick response, and the job didn't take overly long. We had them completely repipe our 98-year-old house with copper. Never wanted to have to deal with floods again!

      They did a few squirrelly things, which we had to pay to have redone, and they left somewhat of a mess for me to clean up, but basically the job is done and hallelujah for that!

      If you are repiping, btw, my General Contractor told me, you are supposed to insulate the hot water lines. They didn't.

      We had a garbage disposal that was leaking, contacted Costello's, and were able to get an appointment the next day.

      Miguel was our service technician, and he was great. Quickly diagnosed that a replacement was needed and explained why, left to pick up the parts, then returned to complete the installation -- all in the same appointment.
      Miguel will also talk you through pro's and con's about different choices (what to fix now, what to wait on, etc.) and explain each step of what he's doing.

      This is our third repair with Costello's (all for different causes). Highly recommended when you have an emergency leak of any kind!

      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.

      Our bathroom faucet handles started loosening, and could not seem be tightened so was rendered unusable. Called Costello's, and Gary answered even at 8:30pm. He had appointments available the very next morning, which we greatly appreciated. A technician, Alex, came by within the window Gary had stated (and Gary even texted to let us know he was en route) and recommended installing a new faucet since the old housings were rusted and the loosening would only occur again in the near future. We took his advice, and I purchased a faucet from Home Depot (it would be a little more $ if he bought himself), and installed it within an hour. Alex cleaned up everything, and was very contentious, as well as friendly. We are very happy with his service and will use Costello's again!

      new service lines!

      Toilet needed to be replaced - Alex and his manager came in and quickly and seamlessly completed the service. Would 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.

      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.

      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!!

      Made a 5-star review on thumbtack but mistakenly spelt the company "castellos". Whoops! Hope this review makes
      up for that mistake a bit.

      No words for how impeccable their services were this evening...Trust me. It is rare that I have no words to say! . Thank you so much to "COSTELLOS BUT NOT "Castellos""

      Special shout out to Miguel, the service technician, for his high level of efficiency within the demanded needs of any business- customer service, speed, quality building rapport/social abilities and for simply just being courteous and friendly . Miguel brings forth a positive additional factor "I LOVE what I do and I got you,"
      and makes you, the customer, feel that true nature he presents.

      CP will be my local go to plumbing service provider when needed.

      Thank you again Miguel and everyone with Costellos Plumbing!!!!!
