"I couldn't have asked for a better company to perform the remodel on my kitchen, downstairs bathroom and a new bathroom addition upstairs. I live in an older home built in the 1930's and previously when new floors were laid the other companies just nailed another layer of underlayment down and off they went. Much to my surprise A Plus Home Remodeling removed all old flooring down to the floor joist and leveled everything prior to the remodel. Once crews came onsite, they were there 6 days a week until complete. They were able to do in all, electrical, plumbing, framing and finish carpentry. A one stop shop. The Kitchen and bathrooms look fantastic. I recommend anyone needing some work done to contact Carlos at A Plus Home Remodeling. Philip S. Spencer, NC"

"Wow! I had the privilege of Bailey helping me with a project to build a pantry and I can’t express how impressed I am with his dedication and craftsmanship. He worked SO hard, all day long, and finished the entire thing in record time. All while having innovated ideas to make the project extremely functional and professional. His craftsmanship was outstanding and his work ethic was the cherry on top. I hope to work with him again soon."

""My husband and I had been so impressed by Greg’s work & professionalism that in 2011 we contracted him to complete a remodel project to finish our basement. Greg handled the project with the utmost honesty, efficiency and ease, keeping us updated throughout the process. He respected our home, more importantly we felt he respected us. His impressive handiwork is especially exhibited in our beautiful woodwork. We are still thrilled with the outcome! Greg is a skilled builder and contractor and I wholeheartedly recommend him to everyone!""

"DHIM Construction is an excellent choice for renovations and construction. I hired them to gut and renovate my medium sized kitchen, from scraping the popcorn ceiling to removing and relaying flooring. Oscar and Brandon were knowledgeable, professional, and very easy to work with. They communicated exceptionally well, and moved the job along, managing everything from demolition to the cabinet source to the granite countertops to electrical and plumbing to the final finish work. The work went quickly and they inspected the progress every step of the way. Their price was reasonable and the work top-notch. I highly recommend DHIM Construction! They are a pleasure to work with."

"Wonderfully! Jonathan planned it all out and worked efficiently and neatly to remodel the barn into more usable space. Part of the barn is workshop, part is garden equipment storage and the upper level is an abundance of household storage. He built a staircase to replace the old ladder which is so much safer and more efficient. Very satisfied with his work."

FAQs for addition to existing structure building service projects in Oak Ridge, NC

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.
