Not too long ago I had a problem with my garbage disposal or something under the sink.

I called Costello plumbing on a Monday morning.

They were at my house Monday midday and the problem was fixed shortly thereafter.

The owner came out and was very informative, assessed the situation and got to work.

They also offer a senior citizen discount so I was happy about that but yes, if you have any type of plumbing problems,

I highly highly highly recommend Costello's plumbing.

They get the job done.

They don't railroad you or your budget.

I'll be using them exclusively going forward, and you should too.

I had the unfortunate experience of having a leaking bath tub faucet. I immediately went to yelp to find the best company and am so happy to have landed at Costellos Plumbing. I got a quick response from the owner and the work was done the next day. Miquel R. and a partner came out to do the work. Miguel was kind, respectful, efficient, knowledgeable and professional. He kept me up to the minute on what was happening and when things were needed. He was very flexible and accommodating of the price. My only sad thing was that they did not leave me my receipt which I would like to have for the 1 year warranty. Hopefully, I will not need to use it. The shower is working better than it ever did and I am very happy with the work that was done. He worked with me on pricing also. I cannot recommend Costello's Plumbing enough and especially Miguel who was awesome!

I had a very good experience with their technician Miguel Romero. He did a thorough assessment of the work needed and pointed out some problems that could be addressed in the future. He was fast and efficient and the work was done cleanly. I had the impression I was dealing with an expert plumber. They also seemed to be flexible with the pricing.

Gary and his crew were great! They helped us identify a few issues we had and resolved it in a very timely manner. We started off with clogged toilets 2 days before Christmas - they came out and helped us snake it, pulling out a bunch of roots. They didn't have their camera so we scheduled another appointment for them to come back out after Christmas. They found another clog, but their 100ft snake was not long enough to clear that clog because our main sewer entry was built too far from it. They advised us to put another entry point closer to the city sewer connection for easier access to clearing the pipes in the future. Gary was knowledgeable and provided detailed information to help us make our decision to move forward with the work, without any pressure. Him and his crew of 3 finished the work in 2 days without any disruption to our lives. He provided his advice for maintenance going forward and CDs with the video from the camera footage to show us before and after their work. We are very happy, thank you Costello Plumbing!

On time! Accountable. Professional. Everything I expect from a skilled repairman. I have a old house with old plumbing. Problems galore. Gary was tip top.

Called them today and Gary, owner, came out within a couple of hours. He quickly diagnosed the problem, ran to get a part and fixed the issue. Price was reasonable compared to other plumbers we have used in the past. Friendly, competent and nice. We will definitely use him again.

I called Gary yesterday and he arrived today exactly on schedule. I had a problem with both my upstairs toilets - one leaked and the other was wobbling. Gary removed both and found that they had not been sealed, they were basically just sitting on the floor with a bit of caulk around the edge. Gary thoroughly cleaned the floors and the under side of the toilets and put in proper seals and replaced the toilets. He did the work very efficiently and left his work area spotless. I would definitely use him again for any plumbing emergency. Forgot to mention he is also a very nice guy.
