"There's a reason Mose is my go-to guy for this type of work. The build-in he completed for my media room looks fantastic, is highly functional and totally elevates the room. Mose and his teammate Reuben are seasoned pros, so it's no surprise that they completed the project on time and within budget. I'll be back for more."

"I happened upon David when he was working on another house and saw the quality of his work firsthand. So, I talked with him about my kitchen and he came and looked at it. It took a little while to get an estimate, because he was busy, but it was well worth the wait. He had a lot of good ideas to share. Instead of doing a few things to improve my kitchen it was totally redone. He was punctual to arrive or he let me know that he couldn't come a day which wasn't very often. The quality of his work was excellent. He met many challenges in this old house,, but he tackled every one . I'm very pleased with my new kitchen! The price was very reasonable. He also took out and put in a water softner. He did some other things as well. He went above and beyond! I would definitely hire him again and in fact we talked about some other things for him to do here."

"John and his crew are the best. Top quality work and really easy to work with. The attention to detail and the craftmanship are top notch. If you want it fast and cheap, this is probably not the company for you. If you want a structure that will stand the test of time and is done right, these are your guys. I will definitely hire John again for my next project."

"Gary and his partner, Forest, were very pleasant to work with. Gary is very professional and can do almost any project. I was building a  kitchen in a former dining room in my 1915 house and needed to remove two windows to make room for the new cabinets. Gary and Forest removed the windows, boarded up the openings, replaced the cedar siding outside, and painted the new boards so that you couldn't tell windows had ever been there. Insulation and sheetrock were installed and taped. I did the painting to save money. They arrived when they said they would and Gary always called if there was a delay. They installed new wiring for the refrigerator, stove, microwave, two switches and 5 can lights, plus installed the cans. Adjusted the circuits in the electrical panel to accommodate the new wiring and installed under counter lighting. 
In January, 2014, Gary built a beautiful corner window bench with storage for me and installed it in the kitchen, replaced old knob and tube wiring in the upstairs, added an outlet in the bathroom, removed old toilet and vanity, installed new vanity and toilet, and installed light fixture. 
I consider Gary the very finest contractor I could have found. He listens to my suggestions, is very amenable to any changes, patiently answers my questions, and makes suggestions if he thinks something may not be feasible or cost effective. I already have a list of future projects waiting for Gary to handle. Anyone hiring him will be very pleased with the whole experience and his costs are very reasonable.

FAQs for addition to existing structure building service projects in London, 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.
