"They replaced my tankless water heater, under sink valves with quarter turn ball valves and three toilets. The price was fair, a little high, but the quality of work and service was excellent. These plumbers know what they are doing. They were timely and had good communication."

"Needed to replace hot water heater and mentioned that when the service call was made and asked that they come to the house with the replacement. They came to do an estimate and wasted three hours after I approved the estimate as he had to go pick up the water heater."

"Such great service!! My water heater went out in my rental property and they were able to hop on the phone with me right away and offer me a quote. Within the next 2 hours someone was at the property - they removed the old water heater and installed a brand new one and were on there way. Cobra Rooter & Plumbing was professional and quick! Will use again in the future."

"Excellent service and will happily recommend them to anyone needing a new water heater. I was so impressed by them that, in spite of the price being a bit higher than the other companies that came out,I hired them on the spot. Due to the bizarre way my water heater is installed, the job ended up taking about 6 hours longer than we expected and I was pleasantly surprised that Dylan, the service technician, was surprised that I expected to be charged more. He told me that they honor the quoted price whether it takes 2 hours or 2 days. He and Anthony, who was in the office, went out of their way to make what was shaping up to be a disaster (I literally had water pouring out around the front panel) into a pleasant experience. Anthony even helped me get financing set up. Bottom line: if you're looking for professionals who go the extra mile to provide excellent service and who genuinely care about solving your problems, I strongly recommend Tucker Hill."

"Glenn was an incredibly knowledgeable educator, above and beyond the other companies we spoke with. He also really didn’t want us getting anything but the best and wholistic options for our family’s situation and home. The warranty was great too! We had a water heater removed and replaced, reverse osmosis filtration installed, and a whole home filter and conditioner fitted. The water tastes great from everywhere in our home! The plumber on site was friendly and quick. 4 months later everything is working perfectly. Glenn was fast and constant with communication the whole time. If you need any work done related to water- highly suggest giving Aquaco and Glenn a call."

"Two valves and a leak were repaired. I started with old rusted main that was leaking. While doing the work I asked to have the hose bib updated and the system sprung a leak that was also repaired. Daniel Medina was awesome. He was friendly, courteous, fast thorough and did a great job. I was so impressed!. Prices seemed a bit high but Daniel did such a great job I barely noticed the sting. Thanks Daniel and thanks Tucker Hill for getting to me in a 'no water in the house' situation, to fully operational with a potential future issue handled in under three hours. That is three hours from the call to Tucker Hill asking for help to thanking Daniel as he drove away, problem solved. Shoot, I'm happy."
