"Remark removed and replaced our large custom composite deck. Double picture frame with contrasting colors and aluminum rails. Fantastic quality construction on the new build. Very satisfied with the new product!!! Chris and his team were super courteous and respectful. Good to work with. Prompt responses to concerns or requested revisions. Would certainly hire this team again - have already recommended them to friends!"

"Since March 2026, Mostaed Construction has tackled six projects at my home: two bathroom tile projects, a large deck replacement, small deck replacement, back siding/front door painting project and front porch column replacements. Mostaed subs included drywall professionals, painters, concrete professionals, and truly superior craftsmen who dealt with installing tile, heated flooring, deck construction and siding replacement. I also have them scheduled for four future projects (kitchen replacement, basement bathroom floor replacement, house painting, and tree removal services. I highly recommend this team of professionals….SIX STARS!"

"Everything was done correctly and properly and allowed me to check off two more projects before winter set in. Both Mark and Simon (and Tim) were professional, but also friendly and easy to talk to. Enjoyed the the time I spent with them. Would highly recommend them, as well as will reach out next spring for some additional projects I have plan for our old house."

FAQs for addition to existing structure building service projects in Franklin, OH

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.
