"From my very first phone call, Tim was extremely helpful and eager to assist, clearly explaining the process and answering all of my questions. Jim visited first to assess the project, and I explained that the work would involve remodeling an existing built‑in furniture unit and transforming it into a functional home office. He fully understood the scope and offered practical input based on his experience. Jim completed the work on time and to a very high standard, with excellent attention to detail and overall quality. The transformation from the original built‑in to the finished home office exceeded my expectations, both in terms of craftsmanship and functionality. It was a pleasure working with Tristate from start to finish, and I would not hesitate to highly recommend them."

"My home cracked and popped horribly even walking on my wood floors. After the issue of structural support columns not being effective, the crew came in and fixed the problem in on day. No more stuck doors or cracks so loud in the middle of the night it sounded like a gunshot. Beautiful job and great price."

"Gary & Fred were very professional. They were friendly and courteous and arrived on time. They went above and beyond in doing the work which they completed on time. They even installed a new front door knob and deadbolt when the original one broke which is not what they were contracted to do. I would definitely recommend them to anyone."

"I hired Bryan to remodel the small master bath in my condo. I originally contacted him in 2018, but due to other issues within my home I had to place this project on hold. One year later I contacted Bryan again, and he was ready to place me on his schedule in two weeks. The price was just slightly higher from the original quote, which was to be expected. His contracts are strait forward and easy to understand. He and his crew are great. They were respectful of the time they started/finished daily due to parking restrictions in my area. Cleaned up the work area every day. Any issues he encountered were discussed so there would be no surprises at the end. They are pros in every sense of the word. The finished product looks great. If I had more projects I would definitely hire him again."

FAQs for addition to existing structure building service projects in California, KY

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.
