We offer complete roof replacements, sunroom installation, and additions. We are an exterior remodeler specializing in James Hardie fiber cement siding, vinyl siding, cedar siding, Sunrooms, 3 Season Room and more!

"Ohio Exteriors completed a three-season room that met all of our expectations. The office staff was responsive, and they provided a custom design that met our needs, particularly with the window options and slope of the roofline. The crew paid attention to details and adjusted well to the challenges that popped up along the way. The work was completed in a timely manner, and the site was kept clean throughout the project."

“The basement finishing experts..." Endless design solutions. Thirty (30) years of experience, and a resume that includes work on over 1,200 basements. Buckeye Basements, Inc. is an award-winning remodeling company that specializes in basement remodeling.

"Excellent. We had several quotes before making a commitment. Our biggest priorities were quality work that we could trust was done right (no cutting corners) and timely completion of the project (no disappearing contractor horror stories), and that is what we got with Buckeye Basements. They presented us with a timeline at the beginning and it was accurate throughout the project, even ending a few days early. This helped us know exactly what to expect, when payments were due, and what days we needed to have decisions made such as paint colors. The crews were professional and kept a clean worksite. We would highly recommend them to family and friends!"

You can sit down with us and we will help you design your new kitchen layout. You will see your future kitchen using our 3D design center. Our showroom features a variety of cabinets, countertops, flooring & hardware. We provide cabinetry that fits your specific budget, from basic to luxurious.

"Complete kitchen remodel (cabinets, counters, sink/fixtures, adding electrical) and flooring replacement on 1st floor; new half bath vanity, top and faucet; outstanding customer support and attention to detail and quality by this team. They are customer-focused, adaptive, accommodating and professional. While there were delays as a major holiday approached, they did everything they could to complete this remodel to our satisfaction, on budget. There were also a few supply-chain issues but were handled fairly and the outcome was wonderful. Their showroom on the west side of Columbus is beautiful but their people (Roman, Diana, Daniel, Nazar, Igor and their team) and how we were treated also impressed us greatly. I really liked how they itemized each portion of the project where I could pick and choose portions I could do myself such as demolition and painting. This saved us several thousand dollars. I would not hesitate to use their services again."

Addition to existing structure building services FAQs

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
