"I would highly recommend Dana King Design Build Remodeling for a remodeling project. We used them for both a master bathroom and a master bedroom remodel. Both rooms turned out absolutely gorgeous. I actually heard about Dana King Design Build Remodeling through a direct mail ad and decided to see what they could do for us and our master bathroom, which was in desperate need of a remodel. We had done remodeling projects in the past, some major, such as extending our previous house to add larger bedrooms and add a jack-and-jill bathroom. We’ve also done two kitchen remodels, a theater addition, lower levels, and a couple of bathrooms. Some of the projects we general-managed, and for others we hired companies, but either way we always seemed to have to manage and “sweat each detail.” Frankly we were so done with that scenario and wanted a complete turn-key operation. That is absolutely what we got with Dana King Design Build Remodeling! When we initially reached out to Dana King Design Build Remodeling, Dana came to our home with Meg, her design architect, and they talked to us. We decided to invest in the design fee to see their ideas and what they could do for us. We are glad we did! Dana King Design Build Remodeling had wonderful ideas and are the perfect mix between personable and professional. With any remodel project there are always issues and delays, and Dana King Design Build Remodeling addressed these minor problems promptly and professionally. Our master bathroom project did not involve moving walls, but did have a large whirlpool tub that needed replacing. The bathroom was completed in late 2019 and we are thrilled with the results. We loved it so much that we decided to hire Dana King Design Build Remodeling to do our master bedroom. I did not think they could outdo themselves, but they did! The master bedroom is spectacular, even more impressive than the bath. As a designer friend of mine said: “I don’t know if I could sleep there because I would want to stay awake enjoying it!” So true, and we agree. For our master bedroom projects we worked with Meg again, and with their designer Michelle. Their ideas and furnishings were over the top and incredibly stunning. They were both easy to work with and communication for both projects was through an app called Basecamp, where everything is documented and all parties involved are notified. Don’t worry if you’re not tech savvy, I’m not, and I figured it out. We could also contact them directly by phone or text, which I also did. The carpentry in the master bedroom, which involved beautiful moldings and “paneling look,” was done by Kent, who did a phenomenal job. Kent also supervised all the trades coming through the house: electricians, blinds, painters, etc. Kent was a pleasure to work with, very conscientious and an all-around nice guy. Dana King Design Build Remodeling followed all safety protocols for Covid-19, including masks, a washing station at the entrance, and sanitizing upon exiting. They were patient with us regarding delaying the project start date, as it was in March of 2020. Even though furnishings were ordered and delivered, they stored all items until we felt comfortable with starting the project. In conclusion, we are extremely pleased with the job Dana King Design Build Remodeling did for our master bathroom and master bedroom. They were not the least expensive, but we held them to high standards for the price paid and they followed through. No regrets!"

"We love our new shed! We hired Tittel Construction to build a custom shed on the site of our previous shed. The concrete pad was there already but has a definite slope from a previous tree growing too close. Connor was able to not only build a great shed, but also make it level on a sloped foundation! He was very patient and helped me design, through Pinterest pics and my rough drawings, the perfect shed including 10 reclaimed windows. I’d highly recommend Tittel Construction."

"Bruce, Dave et al are amazing. They listened, worked with me and my timeline, and gave us such a wonderful, beautiful product; our master bath, and full basement remodel are gorgeous. Bruce is paid weekly based on the work his team does, itemized statement, full disclosure and no surprises. We are hiring them again to add a deck to our home, and cannot wait for the finished product. /Gail & Brett Gordon and family."

Customers say: Quick response

"To be truthful i was very skeptical hiring anyone to put on a new deck because of all the horror stories you hear of contractors taking your deposit and never returning to finish the job. BUTâ ¦ meeting with Jacob Quick made it all very easy. I met with Jacob many times because of my apprehension and having issues with making decisions. After signing a contract, Jacob kept in contact with me on starting date, permit issues, when materials would be delivered, and if there was inclement weather conditions that they could not work that day. From the start of teardown to the finished project, they were there every day at 7:30, making sure that time was ok with me. They had a crew of 4-5 people working all day. When an issue came up, they were up front and we discussed it. I felt very relieved that all the guys were very knowledgeable and experienced. I am picky when it comes to details and the entire crew were all very concerned about the littlest details. Brian was also great at answering my questions as the deck was being built. They wanted me to be highly satisfied and i surely was. Not only did they do an outstanding job building the sturdiest deck around but when they left my house, you couldn't even tell they were thereâ ¦ my yard was clean. Soâ ¦ yes i would hire them again. They made the entire experience easy peasy for me. Also kudos to the other guys on the team who also worked their butts off in the 100 degree weather. Put your mind at ease and hire Jacob Quick with Master Remodeler. You can come by and check out my deck!!"

"We had a master bath & closet remodel. Jackson was not the lowest bid, but we went with them because we felt comfortable with their design, honest approach, willingness to work with us, and their proven quality of work. They did not disappoint. This turned into a pretty big job. And through it all, Jackson was very accomodating, provided great attention to our details and specifications, and did a great job. We are extremely pleased with the finished product. It took a little longer than we hoped, but is well worth the wait."

"We chose Terbrock Remodeling and Construction to build our new addition that consists of a 3rd car garage (with insulation and drywall), covered patio and uncovered patio for a hot tub. And we couldn’t have been more happy with the results. Tom and his crew are experienced craftsmen and they did a fantastic job. Early in the process, Tom was able to take our vision, help us firm up the design and provide a reasonable estimate. And the entire project was completed on budget. I can see why this construction company is in demand. If you’re dreaming of any size construction or remodeling project, I highly recommend taking your vision to Tom and start the process by getting an estimate. You might be surprised how close you can be to having your dreams come true. -Satisfied Customers"

"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."

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

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.
