"We recently remodeled our bathroom with McCormick, and it was a fantastic experience. Khaled was informative, patient, and genuinely helpful, guiding us through choices for a perfect design. The team’s professionalism showed in their punctuality and quality. Every aspect was done with care, from tile placement to lighting. The transformation is truly impressive; the bathroom now feels open and luxurious. We’re beyond pleased with the result and look forward to more projects with them."

"We hired Scott McQueen to totally renovate our existing barn, a very challenging project. We recently purchased this ranch property. The existing barn was quite old, probably built 50 years ago or more. Scott developed a plan to totally renovate it -- new trusses, new concrete floor (previously was just a dirt floor), new roofing, new siding, new electrical, new paint, new and strengthened interior walls, new doors, etc. Unfortunately we tackled the project at a time of high prices for materials and other elements, but Scott worked with us to significantly reduce costs from the original estimate by redesigning some elements of the plan and working with us to explore alternatives. We couldn't be happier with the renovation."

"Mr Neill Dougherty is an excellent custom builder, designer, communicator, and always professional. His prices are more than fair, especially when we saw the finished room!! We were somewhat unsure of exactly how we wanted the room, so Mr Dougherty helped us by showing several options that would work for our Mother-in-law studio addition. The room is absolutely beautiful! I love the flooring and custom tile work Neill created for the kitchen and restroom. Neill kept us up with all stages of the project, and was very accommodating and polite about my changes and "ideas" along the way. He even had an fantastic designer help me with Interior decoration after the apartment was ready! There has not been any issue we had to call back about. We will hire Mr Dougherty for any future building or remodeling we need! We highly recommend him for any project or home build."

From the very beginning, Angel and his team were professional, honest, and incredibly easy to work with. They paid attention to every detail, communicated with us throughout the project, and made sure everything was done to the highest standard. Angel is a reliable contractor who delivers exceptional quality and an stress-free experience, I highly recommend AI Construction. We couldn’t be happier with the results and will definitely be recommending them. Thank you, Angel and the entire team, for bringing our vision to life!"

"If you are looking for a knowledgeable, hardworking and trustworthy company, not to mention a kind, respectful, good communication and good person, Vitaliy owner of AVD Construction is who I highly recommend. Our project started as an owner build ADU garage conversion. We interviewed 3 subcontractors for each initial trade. Vitaliy was initially interviewed for framing, it was immediately evident that he was very knowledgeable about construction and codes. His pricing was fair and within other quotes, so we hired him. After a couple visits, and reviews of blueprints we discovered that Vitaliy was a general contractor. Since we were early on in our project, we would have him bid at each step, which we would choose him every time. As the project progressed Vitaliy would catch errors, by other trades and engineering. Most of these catches saved us time and money. There were times that he would fix some of these errors to help us out and save time. There is a specific example that comes to mind. Concrete sub had just poured their concrete, they took off the garage side door and our larger garage door wouldn't close. I was feeling very uneasy about having access to our garage and home from the street. Vitaliy pulled the door out of the pile of trash, cut it down to fit in opening, put hinges back on and wired garage door closed. I think he could see how happy and grateful I was, I remember saying "I think I'll be able to sleep tonight." Vitaliy said "treat other people's home like it's your own." That really stuck with me. Vitaliy made suggestions along the way, that made sense and often was overlooked by our novice eyes. He explained things, so that we could understand, he taught us so much. We are so grateful and lucky to have found him. We went on to hire AVD Contruction to frame, drywall, tape/mud walls, completely tile 2 bathrooms (floors and showers), Install 2 French doors, windows, all vents, stucco entire sides where new doors and windows were installed, plumb our kid's bathroom. Vitaliy was there for every inspection. Every job he took on, he and his workers were respectful, communicated each step of the way and they always treated our home like it was their own. If I had to do it again, I would have hired AVD Construction to do the whole project."

FAQs for addition to existing structure building service projects in Newcastle, CA

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.
