"After they redid our counter tops and island, we had them paint out cabinets and build shelves up to the ceiling. The communication was on point this time and the results speak for themselves. Would definitely recommend them to anyone for any home project."

"Prosper and the team at Prosper Construction just completed a beautiful renovation of my home. I badly needed new flooring and decided to add other updates as well. So we embarked on the journey to design an addition to our home and redesign the entire front of the house, which included a kitchen remodel as well. I knew that I wanted to replace my carpet with porcelain tile, but I thought that I would leave my existing kitchen tile in place, to save a little money. Prosper convinced me to eliminate all transitions in the flooring and replace the entire house with the new tile, and I am really glad that he did! The house now has a smooth flow and an expansive look that is just gorgeous. The entire experience was beyond worth the investment. The most amazing part of the transformation of my home is my stunning new master bathroom, which Prosper also advised me on."

"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice. Khaled and the team delivered high-quality work within the timeline and our budget. Every detail, from the tile work to the lighting, was beautifully done. They communicated well throughout, keeping us informed at every step, and the end result was truly a spa-like bathroom we can enjoy daily. We’d love to work with them again!"

"John and his team do amazing work. Built a stunning custom office space with a floor to ceiling library, custom cabinets and custom French doors that blended into our existing home design. I’ve owned a number of homes over the years and I’ve never worked with a builder more dedicated to quality and with more experience than Bay."

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