"Derrick was so helpful! He identified and repaired a leak for us, replacing our water filtration system under the kitchen sink. He was persistent and professional. I would absolutely hire him again."

"I emailed Day and Night Plumber after my old water heater started shooting water out the front panel and within 10 minutes I got a phone call from them with an appointment for an estimate with Marin. The quote was very reasonable and after I supplied the Hybrid Water Heater, Marin was able to come install it on Sunday. He was extremely knowledgeable, efficient, and hard working. He finished everything, cleaned up the area, hauled away my old water heater, and showed me how everything worked. He even gave me a military discount and 12 month warranty on labor. If you need a plumber for anything, give Day and Night Plumber a call, they will give you top notch service for a reasonable price."

"I have had Ehrhardt plumbing for numerous plumbing jobs. The Roman Tub Faucet installation was probably the least successful job but still OK. The tech left and the faucet was on a constant drip/flow. I had to call and have the tech return. He said he needed a replacement part. Since the faucet was one I had ordered online -and from company Ehrhardt does not deal with, I needed to find it. I eventually did. The drip fortunately stopped. I still wanted someone to come and recheck it -- didn't seem to work that great. I was told I would have to pay for the recheck. I was disappointed considering I have been a good loyal customer. I opted not to have him come. Previously they have replaced two hot water heaters. I would still call them because for the most part the service has been satisfactory."

"Called Clayton at Aqueduct about mid-morning. At first call went to his VM and I hung up to try later. Clayton called my number back within minutes. I explained my toilet drain issues. He said he could be out about 3-5 same day. He asked if I could text my info to his cell phone number. Clayton texted me about 2:30 that he was on his way. He cleared drain from the cleanout for the MB toilet to pipe feeding main to septic. I realized main hall bath was also clogged. We have someone that uses way too much toilet paper and often! He was able to clear that drain. I would definitely use Clayton's Aqueduct Plumbing services in the future. He is professional, courteous and lets you know exactly when he's coming."

"Both Justin and Charlie came out and were very thorough in explaining the process. I was very pleased and well informed in what was happening when replacing my main water service line. The crew that came out were in time and did a great job in communicating and avoiding disruption to the property. I reached out to my community on recommending a good plumbing company; after a total of about 25 responses, 22 of them suggested Heil Plumbing! Thank you to the family and crew of this company and I will make sure the appreciation is communicated through our social networks."

"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!"
