"Joe and Alex did a great job with the complete demo and rebuild of our front deck. They ensured everything was up to code, structurally sound and the end product was designed the way I wanted. Quality work. I will definitely be hiring them to do my back deck and other projects when the time comes."

"We had Bryan and Julie do a kitchen facelift and were wowed with the results! They put in new countertops and backsplash, installed a new kitchen island light fixture, and painted our existing cabinets a beautifully soft, white color. Bryan also modified an old kitchen desk into a wine cooler/ wine rack area. Julie s design ideas and recommendations were wonderful and she was helpful with our budget. Bryan does his own work and his precision and attention to detail were impressive. They were easy to work with, professional and punctual! We will definitely use them again for our next home project!"

"Doug is excellent to work with. He brought my vision for the fireplace/living room remodel to life through his expert carpentry and design consultation. Great communication throughout the life of the project and he kept an excellent eye on the budget, even suggesting some changes with materials and other items that would save money without impacting the look and quality."

FAQs for addition to existing structure building service projects in Mosby, MO

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.
