"Worst experience ever. Unresponsive, unwilling to complete the work, no communication among the different teams which came to the house to do the work, lying every time I talked with person who gave me the estimate and signed the contract with, lying by a supervisor, and more ? Horrible company."

"OK, so Mr. Frank was very professional. All his team was very professional, very polite. They were on time and they went far and beyond of what they were supposed to do and did not charge me more than what they said, so I am very very very satisfied with the work that Frank did, and I wanted to thank him team for being so wonderful and such a great People, we don’t get that anymore in America, but he definitely gave me that. And I’m so happy that I hired him. I had five different people that I got proposals from, and I called all of them multiple times to check on things. And definitely Frank.

"Charles and Kevin were outstanding! We were very impressed by the notifications to allow us to know precisely when they would arrive. They were very clear throughout the process on what was required, what the process itself entailed, the cost, and how much time was estimated for the project. In addition, they were very professional and friendly! We would highly recommend Charles and Kevin!"

Marvin communicated the process involved, project pricing and returned on the second day with necessary parts to complete the job. The entire experience working with him was seamless and was a great way to start 2026!"

Again a huge thank you to Roland, Brandon, Wayne, Umasis, Dillion, Cliff, Damon, and Thomas. Awesome job ! Tight spot and a deep trench. Happy Holidays ! Hope you get some rest."

"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

"Excellent, efficient, and affordable!"

"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"
