His teams attention to detail, from the foundation to the finishing touches, ensured a seamless integration with our existing structure. Throughout the project, Jasons clear communication and willingness to address our concerns made us feel valued as clients. The addition now feels like an integral part of our home, and we have Jason and his team to thank for that."

"I hired Terry to build a 14'x20' lean to box building with no windows on an existing concrete slab. The slab wasn't checked for level and the building went up without addressing the issue. The slab issue was my fault, but I think a professional should check before building on anything. If someone is concerned for their product I think that person should say I can't build on that because it has an issue. I also understand time is money and once he started i was locked in. I am writing this to help the next guy. A slab check would have taken a minute and this is why it was so grievious to me."

"Allan & the guys working at AC Cornerstone do quality work. They built my house in 2005. I know they build quality because I watched the attention to detail and selection of quality materials that last. In 16 years, I've had only minor/expected maintenance issues. Everything still works. No cracks in the rock. This house is solid and built to last decades. I love this house. Building anything can be stressful with 1000's of choices and unanticipated problems. Allan's friendly personality takes away the stress and he has the knowledge/experience to solve or work around any problem. Happy Long-term Customer"

"From the first contact I made with Tristan from TTT, he was absolutely responsive and customer focused! He came right out after hours to look over my space and get an idea of what we were looking for, and promptly provided me with a bid. He provided several options for materials and structure. He was particularly tuned in to my concerns over structural integrity and durability for our free-standing carport. He laid out the construction schedule and showed up EVERY SINGLE TIME AND DATE he'd committed to. His crews were also very professional, skilled and user-friendly, answering all my questions as they went about their work. I would definitely use TTT again, and I highly recommend them!

"I cannot recommend SPS & Contracting enough. When we first started our search for a GC to build our 3 room addition we did not really know where to start. We met with a few & Ed really separated himself quickly & that quality of work ethic showed in every step of the project. Arrived on time, worked long hours, & my family loves our new addition. A lot of contactors will "tell you" what value they will bring if hired to do a project. Ed & Jesus show by example the value they add to a project. I have already recommended them to neighbors & would hire them again myself in the future."

FAQs for addition to existing structure building service projects in Liberty Hill, TX

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.
