"We are completely satisfied with each aspect of our build. They worked with our HOA and mortgage company, who were both extremely difficult, to make my concept of a garage/shop a reality. Bordeaux has quality contractors from land clearing and the foundation to the builders, roofers, electricians and finishing the exterior. I cannot say enough good things about our experience."

"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."

"We couldn’t be happier with the incredible job Tristan and his team did on our pool deck and pergola! From start to finish, they were professional, hardworking, and exceptionally easy to work with. The entire project was completed quickly without sacrificing quality, and their attention to detail was evident every step of the way. Tristan communicated well throughout the process, made sure everything was done right, and went above and beyond to deliver a finished product that exceeded our expectations. The craftsmanship is outstanding, and the deck has completely transformed our outdoor space. We’ve already received so many compliments on it! If you’re looking for a contractor who is reliable, thorough, efficient, and takes pride in his work, we highly recommend Tristan and his team."

"Moran Construction was hired to remodel our Dock House after it flooded over the July 4th Weekend. Gregg Moran called me back after I left a message on Sunday July 6th. He showed up at our house Monday July 7th & had a bid to us by 9th. He has done a fantastic job putting our Dock House back together! He is excellent at communication & does what he says he is going to do & when he is going to do it. We have hired him to do a few more repairs/projects around our house since the Dock House reconstruction is finished. We would HIGHLY recommend him for any of your construction/remodeling/repair projects."

"THE COMPANY TO HIRE! Knowledgeable, efficient, dependable, very pleasant to work with. They did everything we asked and more at our vacation place. Not only did the finish the job early, and it looks great, we had a big water leak that they came right out and fixed. When I called them, they were there and willing to do what it took to help us out. They are honest and up front about cost and timing. If I could take this company back to our home town, I would!!! Jack of all trades. You won’t regret using these guys. They have welcome us into their J&J family. We feel they are Godsend snd blessed to be a part of J&J FAMILY!"

FAQs for addition to existing structure building service projects in Llano, 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.
