"I want to share my endorsement of David Graf Construction, Inc. I just bought a house with a 600 sq/ft deck that was not structurally sound. It was the peak of Covid and I couldnâ t get a contractor to show up for scheduled appointments. While driving in the neighborhood, I found David Graf on a job and asked him to come by and review my situation. While he was busy managing several jobs and booked out more months, he took pity on me and graciously came by and assessed my situation. He immediately recognized issues could not wait. He sent me a quote that evening and had a crew on-site a day later. The scope of work included structural improvements and a staircase for the deck. He connected me with a designer & engineer and got it all permitted with the county in record time. A few weeks later the work was completed within time estimate and on budget. The crew was fantastic, respectful & polite and always left the worksite tidied and free of debris. More importantly, the quality of work was exceptional. If you have a need for a general contractor for a construction project, I highly recommend you talk to David Graf of David Graf Construction, Inc."

"We had a great experience from start to finish. The crew was professional, communicated well throughout the project, and built a beautiful, high-quality deck that exceeded our expectations. They paid attention to every detail, kept the work area clean, and finished on time. We couldn?t be happier with the final result and would highly recommend them!"

They fully explain equipment, installation and financing leaving no surprises. Very satisfied. Also impressed with the great improvement in our water services and improvements to drinking water, laundry, showers and overall water pressure. Definitely will be sharing this company with neighbors and friends."

"The entire team at National HomeCraft earned 5 star rating starting with Kathy who responded right away on scheduling someone to come to our home for the free consultation. Followed then by Jeff Beback the representative who explained each step of the process to renovate our 30 year old shower. Demolition and then reconstruction with a beautiful acrylic shower was seamless with the work crew Scott and Brandon. They were punctual, hard working and very skilled at removing the old shower and installing the new. And we saved thousands going with National HomeCraft versus our first quote!! Overall an excellent experience start to finish!!"

"I submitted drawings of the garage I wanted built and in a very short time, the plans were ready and approved. AMSCO builders was very efficient in the construction of my garage, even during the rainy month of May here in Central Florida. The unusually wet month presented some problems, but the excellent crew from AMSCO worked tirelessly to finish on schedule. The quality of the building and the workmanship throughout the structure is excellent. Ryan Simmons was upfront with all the expenses and costs and at the final draw, our numbers were exactly as promised. I would recommend AMSCO to anyone considering a new garage."

"When 3 other companies looked at my AC unit they told me it needs to be replaced. The cost of repairing it would be just about the same because my unit uses R22 freon AC tech's refer to it as liquid gold. Mike came out and said it's getting close to needing replacement but not today with a simple fix. I asked about the R22 cost and he explained it to me that some companies just take advantage of it to sell you a new system. Mike repaired my AC for $3000.00 dollars less then my other lowest quote. Why use Mike Harper AC: Mike is not an hourly employee he is the owner he does the inspection and the work. When he doesn't do the work he goes around and checks what his employees did to make sure what they did meets his standards. In my opinion finding Mike Harper AC was like finding a needle in a hay stack."

"Work was drawn out due to our vacation and several unexpected out-of-state funerals. Communication with CGC office staff was 2.5 (on 5 point scale). A payment schedule - when and how much - should have been explained in advance. The work: removed steel bathtub and tile surround, plumbing relocated, new cement board, fancy tile, new plumbing fixtures and glass shower doors installed. Wallpapered dining room walls had light plaster coat first applied to smooth out existing orange peel texture. Excellent attention to pattern matching. Paper waste was minimized."

FAQs for addition to existing structure building service projects in Dunnellon, FL

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.
