"Caldwell Construction and Handyman Services took care of a problem with a window and did not charge me. I was not there when he repaired it so he called me immediately upon completion to give me the report. Thanks for the great service!"

"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice.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!"

"Michael and team did such an amazing job on our bathroom remodel. They took our tiny, dysfunctional bathroom and turned it into a true master bathroom oasis in a short amount of time during the holiday season. When they had the space down to the studs, Michael sat down with us and discussed in detail the best possible use of the space and we couldn’t be happier with our final decision after going through the options. Michael was great at communicating and we still stay in touch to this day, which we truly appreciate. Great team who does great work and I will absolutely be giving Waters Construction a call for any and all future home renovations. I’ll let the pictures do the rest of the talking."

"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 hired Joe to do a very large project which included a major kitchen remodel, building a 400 sq foot vaulted addition with skylights, flooring across the entirety of the main space, full 1000 square foot trex deck with accommodation for a hot tub, and side patio. Joe is a 1 man shop. He did everything from framing, drywall, electrical, insulation, roofing, flooring, cabinet installation, and finish work. He was very easy to communicate with and worked with us on change orders as the project developed/progressed. Errors were very rare and quickly corrected when they occurred. This is our 2nd time hiring Joe for a big project and have hired him for other small projects. We would gladly have Joe work for us again on an y future project."

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