"We recently had the unfortunate experience of working with Character Companies Inc., and as government civil servants and veterans, we were deeply disappointed. The price of renovating two bathrooms and installing new LVP flooring at $70K (original quote: $84K) seemed excessive, but we hoped that the quality of service would justify the cost. Sadly, that was not the case, and it has cost us the chance to rent out our home while we are deployed to Iraq. From start to finish, the experience was a nightmare. The project management was abysmal, with multiple delays that extended the timeline one month beyond the agreed schedule. It took over two months to do just two bathrooms and replace flooring when the original timeline was four weeks. This company demonstrated a shocking lack of professionalism and accountability throughout the process. The design work was utterly incompetent, failing to conform to the existing plumbing structure in our bathrooms. The contractor disregarded our repeated attempts to bring attention to design flaws and forced the installation of bathroom vanities by performing a â carpentry fixâ that left us with two top drawers sealed shut, one bottom drawer with a cutout, and one fully functional drawer. One month after installation, one vanity separated from the wall and had to be reattached. Our allegations of Character charging us for high-end fixtures and installing cheaper ones were ignored. The final straw was the damage done to our marble floors. Instead of offering a repair or replacement, the contractor covered it with LVP and then charged us at the end of the project for the extra costs of the LVP that they incurred to cover up the damage! This was deceitful and completely unacceptable. The CEOâ s disregard for customer satisfaction and maintaining basic work standards is unforgivable. The only thing he did well was apologize profusely, not caring about fixing any problems. During a phone call, he admitted that our project was a â dumpster fireâ yet didnâ t offer any concessions. We strongly advise anyone considering Character Companies Inc. to stay far away. Their poor project management, substandard design, shoddy craftsmanship, and unprofessional conduct have left us with a costly mess that will take more time and money to fix. Protect yourself and go with an experienced, reputable company."

"We had an exceptional experience with Johnathan, Jeffry, and their team. Their professionalism, friendliness, and expertise stood out from the start to the finish of our basement project. The process was smooth, transparent, and free of surprises, with clear cost and material outlines. We appreciated their flexibility in allowing us to choose different materials and only charging the price difference. When we added more work mid-project, they were accommodating and maintained high-quality workmanship. They provided a wide selection of cabinets, flooring, tiles, mirrors, and bathroom faucets. The project was completed on time and within budget. We are thrilled with the results and plan to work with them again. Everyone who has seen our basement loves it! Overall, we highly recommend their services."

"I would HIGHLY recommend US builders for any home remodeling project. I saw the quality of their work when they did a total kitchen remodel for my neighbor. The quality was top notch so I hired them to repair the outside and inside of my home when a car, traveling at a high rate of speed crashed into the front of our home. Workmanship is superb, they arrive on time, have the skills and resources to do the job, and they clean up at the end of every day. They same workers were at the job site start to finish, they could easily problem solve unique issues. They repaired and painted drywall, put on new siding and new windows, replaced ceramic tile in the foyer, and "sistered" support beams around the stairwell. PLUS they worked seamlessly with the insurance company!!!!"

"With so many scams these days, it is hard to trust people. You can 100 percent trust Scott and his team. From the beginning of the process, Scott and his team surpassed my very high expectations.
