"The Acosta team was fantastic. We asked for a quote on a renovation, and they were out the same day to review the work and gave me a fantastic option. They started 2 weeks later and were prop, efficient, and the work was done flawlessly. I would highly recommend them for any construction projects you have."

"Considering the scope of the project everything went really well. When working with an existing house “surprises” are to be expected and we were pleased with Duan’s ability to think outside the box in providing suggestions for resolving challenges. We also appreciated the aesthetic approach to making the house into a home that we continue to enjoy without regrets nor wishing we had done something differently."

"I?ve worked with literally 100?s of Contractors over my years, both personally and in my Real Estate and Restaurant Career. Salt & Pepper Design & Construction, LLC is a RARE FIND! Their quality of work is literally the best, their employees well-trained and have a real work ethic and respect for the job?s needs (example, daily cleanup was exceptional). In addition, I am very particular about the work product details, i.e., not easy to please, and yet I was amazed at their great and very timely performance. In this case, it was an insurance claim, and they made things very smooth. Also, they helped with extra work that I needed, very impressed/happy, and you will be too! Nadav does an outstanding job, and we are hoping to hire him to build our next custom home! Shhh, did I shoot myself in the foot, because now they?ll get too busy and I won?t be able to use him again? haha. Get them on your job now, you won?t be disappointed, and that is the truth!"

"I needed an exterior door installed which also required installing the exterior light and concrete steps. The entire project went better than expected. All trades were punctual and professional. Joe was a pleasure to work with and was always responsive. The quality of work was worth every penny and I would definitely use them again."

FAQs for addition to existing structure building service projects in Oldsmar, FL

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.
