"I hired Blue Horizon Construction for a fully custom home build. I worked with them from site selection, to finding an architect, to demo, site prep and build, including sourcing all materials. They stood out for their attention to timelines and our home was built in the best timeframe possible, while managing cost and quality well. Happy to recommend them to anyone looking to do a full build, major remodel, or other project."

"We converted a sun room and kitchen into a larger kitchen. Claudio handled everything including installing a ceiling beam to replace a structural wall. It was a complete transformation. The craftsmanship on the part of all of the subcontractors was excellent. Claudio’s strength is getting the job done- he carries out your plans."

"My husband and I met with Carson and explained what kind of deck we wanted built on the back of the house. We wanted a deck to cover an old patio and extend from the french doors in the living room to the back door of the house. He had some great suggestions about the layout of the deck and stairs. The deck turned out great and Carson was great to work with during the four days it took to build the deck."

"Freeman Repair and Remodel was very professional from start to finish. From the initial consultation wherein we discussed and finalized an overall design/construction plan to the final execution, Derek and his team came every morning and worked all day until the project was complete. I would hire them again in an instant!"

"They added an in-law space, bedroom, full bathroom, large closet and laundry closet, and tied it into an existing bedroom to be used as a sitting room. Start to finish, pour foundation, siding, windows, roofing, HVAC, flooring, painting. Very easy to communicate, very willing to work with your needs/concerns. They definitely know the business. Fair pricing, easy billing and payment. No hassles. After that addition was finished, I hired them to do an upgrade in the kitchen. Definitely recommend and would use them again."

FAQs for addition to existing structure building service projects in Summerville, SC

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.
