"I couldn’t be happier with how my basement remodel turned out! From start to finish, the team was professional, communicative, and incredibly detail-oriented. They helped transform what used to be an ok man cave to a custom at home personal sports bar!! The craftsmanship is top-notch —lighting, and trim work are all flawless. They also stayed right on schedule and within budget, which is rare these days. I especially appreciated how they communicated and was not thrown off by the ongoing questions and changes that was thrown at them. Now we have a beautiful new living area that’s perfect for family gatherings and guests. I’d absolutely recommend this company to anyone looking to remodel their basement or any part of their home. Outstanding work! We will be giving them a call in a few months to remodel our master bathroom. Great guys not only as contractors but in general also made new friends!!!"

"Fabulous job! Met up with Mr. Harris to discuss my concept. I wanted a carport built on my existing driveway to park my Mini Cooper. My concept was for 4 posts, he recommended 6 to accommodate the weight of the tiled roof. He built the posts on pillars that he poured 3 feet into the ground. It has gutters with covers on either side. The finished structure is quite impressive. Me and my Mini love it."

"Trevor and his team did a brilliant job with the renovations of the house that was not in good shape prior. He was communicative and available to chat at all times to provide updates. The attention to detail on all tasks is what impressed the most. He was flexing with his pricing and got the job done before estimated completion date. I would definitely use his services again."

"Kimberly and her team were excellent. She and her team finished our basement. She was very professional, worked well with our designer, listened to our needs and brought great ideas. Her communication and transparency throughout the process were outstanding and the finished product completely reflected the vision. We have gladly referred her to friends for other projects and will continue to do so."

"Pablo is the best contractor I have ever hired in my life (age 67). He gave reasonable estimates in a extremely professional way. His subcontractors to do the tiling and excavation did perfect work done expeditiously. They were no nonsense but very friendly and were frankly, a joy to have around the house. My bathroom belongs in a design magazine. In the lifetime I have left, I will hire Pablo and Simplicity Construction for any construction job for everything this house needs. He is also a terrific guy. On time, within budget, beautiful work, friendly and dependable work. What else is left?"

FAQs for addition to existing structure building service projects in Union City, GA

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.
