" 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!"

"Leo was very helpful and quick to respond. We’re happy with how our 2 bathrooms turned out. Project was completed within the time promised. Our only complaint is that the workers did not clean up very well. But overall, we’re satisfied and we’ll use them again. "

"We hired Streamline to replace a support beam in our kitchen that was too small. They came out and looked and gave us a quote. They started on time and stayed until the job was done. It took several days, but Mark and Harry were in constant contact and communication with them was great. We didn’t have to worry about the little things that pop up on jobs like this. They did exactly what they promised and even came back a few extra times to make sure it was perfect. Everything about this team was just wonderful. My wife and I are extremely grateful for their effort and would absolutely hire them again "

"We found Golden State HS after our last contractor didn't quite meet the standards and really put a bad taste in our mouth in regards to contractors. All of that changed once we decided to work with Lilith and her team who not overseen the project but ensure our new home was built beautifully and even better than we could have imagined it. We loved how thorough Golden State HS's team communicated every step and the reality of the process. Now we not only have a wonderfully constructed home with a pool, tennis court and beautifully landscaped property (they do it all), but we have what really feels like home. I would not only be reaching out to them for my next project, but i will also be referring them to everyone we know."

"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. "

"Not well, Eddie does not do the work but has young kids who do not speak English do the work. We can not communicate with them because Eddie leaves the premises for periods of time. We could have given him more jobs in other locations but do not like the quality of work. We will not be hiring him again. Thank good it was not a larger project."

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