"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."

"This company gets a 0 rating from me. My experience with Alltecs was terrible please do you research on this company before hiring them I even encourage you to go and physically see work that they have done instead of relying on their photos. I would never recommend their company for anything. I hired Alltecs for a 203K rehab July 2021 by March 2023 they quit and nothing was completed in my house. Alltecs had already been paid a substantial amount of money, for a totally f....ed up job and to add Insult to injury Dawnta Million filed a Mechanics Lien on my property in which he never enforced. The nerve of somebody who don't pay his subcontractors (found that out later) so please please please don't get defrauded by Alltecs like I did."

They scheduled the work promptly and showed up on time. Unexpected issues were discovered that required a second trip and additional work. They communicated everything clearly and the additional costs were handled separately and transparently. They also cleaned up after the work was done. I would hire them again."
