"Was looking for a plumber to replace a leaking water heater.All the plumbers I talked to had to have someone come for a estimate and then someone to replace the water heater in a day or two. Robert came 20 minutes after I talked to him,installed the heater the same day and the install was top notch. I will be calling him again for some other plumbing issues I need fixed .If you need a fast ,dependable plumber,call Robert"

"We were in the need of a new plumber and we chose Dan Lavigne through Home Advisor. Dan was very prompt in calling us back to make an appointment. Over the phone, we told him that we needed to install a new toilet and to repair an existing one. He was very courteous and professional and came out within a reasonable time frame to do the work for us. He did an excellent job and we are very pleased with his service and pricing. We have other small jobs for him and we are definitely calling him back! He is great and we highly recommend him."

"Wanda?s is awesome! My old electric hot water heater tank finally retired to the recycling bin. I called on Tuesday evening and spoke to a knowledgeable technician named Chad. I told him what my old unit was doing and he said it definitely needs a replacement after 17 years. He then asked how the home is heated. And then gave me the 2 options for my home. He patiently explained the differences between the hybrid heat pump unit vs the electric one that was presently on its way out. He answered all my newbie questions. He explained the pricing between the two units. I told him I have to discuss everything with the cfo and I would call back Wednesday morning. He also told me they would get me on the schedule for tomorrow or the next day. That was amazing. I called the next day and spoke with Amanda to schedule me in the following day. Chad showed up the following morning and did an awesome job. He was very polite and knew his job well. I am very satisfied so far with Wanda?s."

"When our existing water tank started to falter we knew we needed to upgrade. Derry Plumbing and Heating installed a phenomenal tankless system for our 3800+ sq foot home and we never had a reason to complain. Our energy costs went down and we always had hot water for our family of 5 and numerous guests."

"The plumber was professional, courteous and did a good job. However, it was unreasonably expensive. $550.00 to replace the cartridge in my shower faucet. The work took about 1 1/5 hours including about 40 minutes to go pick up the part. I was charged an additional $140.00 just because he did not have the part with him. My faucet is a very common Kohler faucet."
