"We were extremely impressed with the craftsmanship that Bill brought to the job. He made several suggestions that improved upon our initial design/ideas and brought the job home in the time-frame and for the cost quoted. We are already in discussion to have him do some additional work for us."

"Mose is very talented and easy to work with. I sent him several pictures of fireplace surrounds I liked. He built a prototype and came to the house to discuss and confirm design options before building it in his workshop (no mess at our house was a plus). Typical of an old house, the installation required custom fitting. He took his time and made sure every detail was right. It will look even better once we paint and make it the showcase of the room!"

"Tim did a superb job of tearing out the old, putting in the new and repairing the active wet spots in the kitchen ceiling. I feel that his estimates were fair and reasonable and the craftsmanship was a world of difference from the previous subpar job I had done. He is very timely, works consistently and stays on schedule. I can't say enough how happy I am with his end result on this project! I'll be having him back to do another bathroom soon!"

"We hired Diamond in the Rough Construction for a home addition, and while the finished result looks good at first glance, the process was full of issues and cost us much more than expected. We chose Diamond because of Abby, the salesperson, who was incredibly helpful and responsive. However, she left midway through the project, and we missed her support. Addison, the project manager, did his best but was left to handle more than he should have. The owners, Joe and Mike, were completely absent ? no check-ins or follow-ups, even when major issues arose.There were significant mistakes, like framing the windows to the wrong size, and we were blamed for "approving the wrong windows." HVAC was also forgotten until after construction started, forcing us to pay thousands more. The trim was poorly finished with putty that didn?t match the color of the pre-painted trim, and the solution was simply to cover the nail holes with a paint pen. In the end, we can?t recommend Diamond in the Rough"

FAQs for addition to existing structure building service projects in Lewis Center, OH

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
