"I’ve worked with Mike and his team for years on all kinds of projects, and they’ve always been amazing to work with. The quality of their work is top-notch, they stay on budget, and everything runs smoothly from start to finish. Their design sense is excellent and they always manage to get things done right on time. I can’t recommend them enough, truly a reliable, talented, and easy-to-work-with crew."

"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."

"We recently had our bathrooms remodeled by AI Construction, and the entire experience was absolutely outstanding! 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!"

"Matthew and his crew added a new bathroom in my 1930s house in Grass Valley. Lots of structural challenges which they worked through easily. Or at least they made it look easy. Very professional crew and subs with high standards for quality. The project cost more than I expected but I think that s par for the course in home projects and Matthew communicated changes timely and clearly. I did some work myself which I appreciated Matthews willingness and support of my participation in the project. Overall very happy with my new bathroom!"

"Over the years I have worked with several contractors/builders and Marksman Builders has been the best. They delivered on every aspect of our complete older home remodel. Last summer we started with just ideas on a piece of paper and Emma and her team worked with the designer, engineer to retain the charm of our older home and give it an open modern look. The entire process from obtaining building permits to the final details were professionally completed within the estimated timeline and budget. As the project took shape we had several change orders that were seamlessly integrated into project. Friends, family, and other building professionals have commented on how “awesome” our new house looks. Marksman Builders is now building a very custom engineered carport and garage for us with the same professionalism and attention to every detail. I was not sure it could even be built given the terrain and larger granite boulders. They simply incorporated the boulders in the build."

FAQs for addition to existing structure building service projects in Colfax, 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.
