Customers say: True professional

"Andy's crew is very professional and did a great job. My home was difficult to get drywall into. They carried each sheet upstairs. Walls finished very well. Dedicated spray equipment created smooth application of knock down texture. Ceilings Looks great. No damage. No surprises. Priced right, but they weren't the cheapest option. On time. No excuses. They protected my property and cleaned up after themselves. As a property manager, I will definitely use Scott's again."

"deWit Construction & Remodeling went well above and beyond my wife's and my expectations!
We had spent countless hours designing our large custom home addition that consisted of vaulted upper level ceilings, 3 bedrooms (2 guest and 1 master with a large walk-in closet), 3 bathrooms with custom showers, 2 offices, 1 huge 'Great Room', 1 large entry / mud room, 1 storage room, and 1 large 3-car garage. We then decided that we wanted to do much of the work
ourselves, taking on the responsibility of General Contractor for the project, and hiring sub-contractors to complete segments of the project that we weren't equipped to handle on our own.
To say this was a massive undertaking would be a gross understatement. Locating quality sub-contractors was one very tall hurdle that we hadn't taken into consideration during the planning phase. We found that they were few and far between, that many we were able to locate wanted to charge an arm-and-leg for 'custom' work (well outside of our budget), and that some were straight up unreliable and deceitful.
Our previous framing sub-contractor had left a bitter taste with us, so we practiced great diligence in selecting our next. (Note: Long story short, we had to take our previous framing sub-contractor to court in order to recover our down payment due to zero work being completed and multiple promises broken and deadlines missed.) We were pleasantly surprised when we met and spoke with Neil deWit about our project and desires for the work that his crew would be preforming. Neil was very professional in taking the time to listen to and talk with us about the project layout, time-frame and budget, etc. Once we chose to go with deWit C & R, it wasn't long before his crew was onsite and working. We couldn't have asked for nicer, professional guys to have working on our property. We didn't notice any yelling or profanity. They always dressed well and their equipment was always clean and well maintained, and put away at the end of the day. Oh, and their craftsmanship was second to none.
Earlier we mentioned some homeowner design flaws that deWit C & R encountered; well they tackled them head on and found creative ways to make everything work. Most 1st level wall studs had to be individually measured and cut due to fluctuations in the concrete foundation and floor. Wall, door and window locations and dimensions had to be altered in order to make our design work without drastically changing our initial layout. Everything was communicated with us very well by the head carpenter on the project and Neil, and we were involved in all major change decisions. It was awesome to see our project being fleshed out in front of our very eyes and knowing that it was being built with such great quality craftsmanship.
We wanted to roof the existing structure and the addition at  the same time, so as soon as the deWit C & R crew had finished nailing down the roof sheeting, we went to work on removing the worn out shingles from the existing roof. We had an old dump truck that was on its last leg, which we began using for catching the old shingles. We could barely get and keep it running. The next morning, the deWit C & R head carpenter show up pulling one of their nice dump trailers and asked me if we wanted to use it at no extra charge. We were blown away!
We couldn?t be happier with how things turned out.  We officially have our dream home and we owe a ton of credit to deWit Construction and Remodeling! We honestly don?t think we could have completed it without their experience, professionalism and willingness to work with us within our budget. There isn?t a single design modification that we are unhappy with, and the structure is super straight, solid, quiet and water tight.
We can?t say enough good things about deWit Construction and Remodeling. We?re happy to drop their name anytime we learn of an upcoming local project.

"From the first phone call to David(Daughenbaugh Restoration owner) to the closing of our project we are so pleased with his services and his whole team. David was always there to answer questions promptly. His team was very professional and very skilled tradesman! Which now days you really have to worry about that. We would hire Daughenbaugh Restoration again without a hesitation. We are actually talking about adding a addition already and David will be doing that project for us as well!"

"Des Moines Area Roofing was professional, trustworthy, and demonstrated excellent attention to detail from initial contact to job completion. Cleanup was so thorough that the next day you wouldn't even know that such a major project had taken place. It has been 2 weeks since the new roofs and we haven't seen even one stray nail left behind (and they did a complete tear down to both buildings, right down to the wood). An excellent company with which to do business. I offer my highest possible recommendation."

"Our 100+ year old house had some very real structural problems (some of which couldnâ t be totally evaluated until some walls were opened up) but Scott was very honest when presenting what needed to be done. He was accurate on the timeline, and he and his crew showed up every day. Communication was good - we always knew at what stage the project was at, and anytime there was something unexpected that came up, we always knew about it. I felt that the pricing was more than fair and I would definitely use Essence Construction in the future."

FAQs for addition to existing structure building service projects in Knoxville, IA

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.
