"It went amazing. Paid the extra bucks for emergency service, because of our smallish waterfall, looking leak, sprouting from a bathroom pipe, enough to puddle water onto our basement/laundry room floor. Initially, spoke to Chris, who was pleasant and upfront with the per hour fees, for emergency services. He sent us Tim, who was hesitant at first, due to the location of the leak, but his experience and knowledge, enabled him to decipher the location of our leak and fix it. A quick trip to Lowes, where he promptly returned and in 90 minutes, the job was done. A week later and the valve is bone dry. Yay!!!"

"They replaced my leaking Poly water line from the street to the house with a new copper line. They tried to pull the new line through but were unsuccessful so they eventually had to trench through my yard to install the new copper line. In order to do this, they did have to cut through my concrete driveway which I had to get patched. After some adjustments were made with the new water pressure valve the system works great."

"The entire team did a great job. They were responsive and worked to my timeline. Main supply line replacement is not pleasant but they made the best of a difficult situation."

"My guy at Abbott’s was very professional. He came to look at my pipes. First we had the sewer line camered to see if there were any issues. He gave me a good price. We didn’t even need to repair the sewer line so I was thankful. The guy was very helpful and talked with me through other possible issues I may have. He cleaned up and headed out after providing great service. I’ll go with Abbott if I have any other plumbing needs. Thank you"

"I had a sewer backup in my basement. Used Angi’s list and gave RTillery, Alex, a call. They were fantastic - great estimate, responsive, professional, courteous, quick in all their responses, the list goes on. I started with replacing the inside cast iron pipe. Alex even added a clean out. He and his crew were prompt, always polite and professional. They didn’t seem to mind my popping in to watch. The line was replaced in a day and a half w/ minimal water outage. After going back and forth I decided to replace the outside pipes. Alex provided several options. Other estimates would dig up the yard, sidewalk and driveway, replace the cast iron and terra cotta, but no cement work. RTillery slid the new PVC inside the terra cotta which was cheaper and less to dig up and they replaced the sidewalk! Only one other company offered to sleeve the PVC and it cost more! RTillery even came back to fix an issue they noticed doing their final checks. Wow! Can’t recommend these guys enough!"

"John is a good man, with experience to prove it. We have hired him twice now, to sort out a flooded basement (care of the City of Baltimore & their contractor, Spiniello), and then to retrofit all the horizontal pipes in our row home. Not only did he and his team solve our issues, but they made it look good. For a 120 year old row home, you can imagine the plumbing has been subject to a number of revisions, so it was a real pleasure to see them cut it all out (pipes corroded down to a pin hole), and replace every water bearing line with a singular, clear & straightforward system of logically placed cut-off valves, t-joints and what-have-you.
Because we had already had him out to solve a 1400 dollar flood problem the city blamed us for (and which later turned out to be their fault but they are not willing to pay for), he offered us this super low rate to get all the rest* upgraded (*all the main branches had been upgraded already, namely the verticals to the second floor). Johns original quote was for 1250 to do all the horizontals, so since i had him there i asked if he could run gas to our stove. Because of our recent purchases from him and since he was already there, he ran all the gas and got me two (all you need is one) gas cut off valves for an additional 150 bucks. 
Home Depot quoted me 500 for the same job.
John's number resides firmly in my phone.

"James did multiple jobs for me after diagnosing the actual problem. Correcting the issue required james to replace part of an old pipe which could only be accessed through a ceiling. James not only fixed the plumbing issue, he completed the carpentry work and repaired the ceiling. He also replaced my shower floor and the tiles surrounding it. James also replaced faucets on my utility sink. James is exceptionally knowledgeable, professional, and a master of his craft. I highly recommend hiring him for your plumbing needs and wants."

"As it turned out to be an A/C problem Rob didn't perform the service otherwise I'd have hired him for the repair on the spot.  He explained our issue and assured me that there wouldn't be any worse water in our basement while we were away which relieved my concern.  Rob also answered questions I had about our hot water heater.  He was nice and knowledgeable.  We'll definitely call him with our next plumbing project or problem.
