"I could not be happier with the final product! The first pic is the old bathroom from the 60s when the house was built. The rest are the final rebuild and it looks great. I would highly recommend VMK Remodeling for any project that you might have. I am also going to get a bid on redoing the deck on the back of the house as Vince's company does decks as well! Thanks to his great crew as well, great people to work with."

"I was extremely please with the job that was completed. The exterior of my house looks great. Dennis and his crew were professional and courteous. Even as they were at removing the existing siding, gutter, etc., they always cleaned up before leaving for the day. I appreciated this especially because this was not just a one day job. They answered all my questions and kept me in the loop throughout the whole process. I plan on using this company again for some projects inside my house. Would recommend them to others."

"The entire experience with Josh Dunn and his team went extremely well. I had another contractor over to look at the space, and his estimate was 30k, he really had no good ideas for what to do with the originally awkward layout, and he advised that I should move my two kids (ages 1 and 4) out of the upstairs during the remodel. Josh walked in and immediately envisioned what to do with the space and came in with a lower estimate. He and Mike worked meticulously, controlled dust, and cleaned up every afternoon before they left. They did any and all sawing and tile-cutting outside. My baby took naps in the basement, but both my kids slept at night in their own beds in their rooms, and I never worried about dust. Josh and Mike are polite and professional, keep you informed of the process, and are also very good at what they do. No drywall seam is visible, no tile is crooked, and the paint job is extremely clean. Our remodel was extensive enough that we needed city (Richmond Heights) permits, and that required that separate electricians and plumbers do that work and that everything (electrical, plumbing, building) be inspected two times. All of that slowed things down, but Josh and Mike communicated so well and kept everything so neat that I had no complaints. They also subcontracted out to workers who were as nice and professional as they are. I will have Dunn Home Improvements do any home remodeling project, large or small, that arises in the future."

"Excellent, Zykan was easy to work with. They do quality work, and they worked very well with another contractor I used to install stone on the front of house. I highly recommend them for siding and roofing projects."

FAQs for addition to existing structure building service projects in O Fallon, IL

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.
