"I'm not joshing you, but Josh Powers was great. We had a ton of questions and he answered them in a fast manner. Great work, high-quality and no complaints. He was patient when I drove back to get him assistance on his end on a Friday afternoon. I'd recommend him to anyone in Central Ohio for handyman duties, electrical, carpenter work, and, especially painting. He did a great job with painting three rooms and a kitchen--everything is top-notch!"

“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!"

"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."

Addition to existing structure building services FAQs

Building an in-law suite takes between two and seven months. Converting an existing basement, attic, or room can be done in about two months. Constructing a new addition or detached suite often takes four to five months for construction, plus one to two months for permits. The bigger the suite, the longer it will take. 

Yes, you can build an in-law suite in your backyard if you meet local building codes and zoning regulations. An in-law suite often occupies 300 to 800 square feet. Be sure to follow size restrictions, utility separations, and entrance requirements. Hiring a qualified contractor ensures you meet all regulatory requirements because they can pull permits, double-check local code, and gather other skilled pros to work on your suite.
