"Joe and Dan are very professional and have competitive prices. They did a stellar job removing our old water heater and installing the new one. They were enjoyable to work with and helpful with our questions/concerns. We definitely recommend Joe and Dan for any water heater needs. Thank you!"

"Had a gas leak that needed to be fixed. He came same day and did great work. He was upfront about prices and told me if the fix wasn’t as easy as it looked he would have to charge more but he would let me know before he did that. He even found a separate issue and told me the tank above my water heater was rusting from the inside out and needed to be fixed. Would definitely hire again "

Customers say: Super punctual

"Don't waste your time because that's all this company will do is WASTE YOUR TIME. I had an appt for 10/20 between 8-12pm. Never got a call, nor a visit. Called to find out why an d was told that they sent a text informing of running late which I never got. Received callback from Nicole informing of non received text stating she would set up visit so that I would be 1st stop. I requested today 10/22 and was assured she personally would call me around 8:30am and tech would be here by 9am. It's now 9:37am and I've again yet to hear from Nicole nor a tech. DON'T WASTE YOUR TIME BECAUSE LEN THE PLUMBER SURE WILL WASTE YOUR TIME. UNPROFESSIONAL AND NOT RECOMMENDED!!!!!"

"Initial rep was great and informative. Felt comfortable with initial sale. Hardly had any contact from customer service except for the payments. There were several delays that we were not informed about unless we called to ask. Took 7 months before they showed up to begin project. Only 1 person was sent to build steps. Took a week. Hard worked, hardly took a break. Had to call again to see when they would come to pour patio. Never knew when they were coming, they just showed up. Hardly spoke with the homeowners. Inspection paperwork was just left on porch. Additional paperwork that is "required by the County" had to be completed by homeowner and taken to Court house to be notarized and filed and also provide a copy back to Long Fence. Time sensitive materials which added to homeowners to-do list. Gave this contract to LF on the surface of their history and appearance of a 'good local company' but should have stayed with original contactors in VA. Puddle of water forms when it rains"
