" Zacarias Remodeling Construction did an amazing job on my brand new kitchen! I wanted my kitchen to be done before Christmas and they worked above and beyond to complete it! Oscar (the Owner) would come to see how the project was progressing and inspect the finished work and made sure if we had any concerns or questions. The workers are professional and hard workers!! They also made sure everything was clean before leaving for the day. Suzanne (Estimator/Designer) was there 100% of the time for questions, advice and opinion on the design. Awesome to work with! I am very happy with my kitchen and highly recommend them!"

"A better start and end to the day begins with a well-designed bathroom. My Remodeling Group refreshed this space by rethinking layout and materials to create balance and ease. Clean tile work, modern fixtures, and thoughtful lighting choices brought clarity and comfort together, turning an outdated bathroom into a calm, organized space built for long-term use."

"We were looking to remodel our kitchen or bath for a few years. We kept getting estimates from different companies and always felt the price was off or the person was not a good fit. Then, finally, we met Shai with Cal Green Remodeling. What a great guy! He is very upfront and honest about what we can expect in terms of cost and work flow. Because of his honest approach, we hired him. We felt he gave us the good and bad and how to resolve the bad as well. In the end, the process was fairly smooth, and the few hick-ups we had, for example, the city and their permit process, were well explained to us at the beginning, so we were ready. Our kitchen or bath looks amazing, and I plan to work with Cal Green Remodeling again. Thanks Shai!"

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