"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!"

"Oscar truly stands out as a contractor who cares deeply about his clients, and that’s exactly how he made me feel. I reached out to five different contractors to assess my bathroom and offer ideas, but my experiences varied significantly. Some were overly sales-driven, others dismissed my ideas entirely, and one didn’t even follow up with an estimate. Oscar, however, was a breath of fresh air. He arrived on time, listened attentively to my ideas, and offered thoughtful suggestions. He was highly collaborative with the other workers on site, making sure everything was well coordinated. Oscar's expertise in the industry is evident, and he’s exceptionally creative when it comes to problem-solving. When he identified additional challenges during the project, he took the time to offer practical solutions, demonstrating his commitment to delivering the best result. Oscar has earned my trust and will be my go-to contractor for any future projects. I highly recommend him to anyone in need of a reliable, skilled, and dedicated professional"

FAQs for second story addition building service projects in San Mateo, CA
Converting a vaulted ceiling into a second floor requires three to six months from planning to completion. The process begins with several weeks of design and engineering, followed by permit applications, which vary in processing time by location.
Construction itself spans several months, including framing, systems installation, and finishing work. Weather conditions, contractor availability, and inspection schedules can all influence your project timeline.
Several factors could make your conversion challenging or impossible. Inadequate roof support structures, insufficient foundation capacity, or problematic truss configurations might require prohibitively expensive modifications.
Some homes lack the minimum ceiling height (12 feet at the lowest point) needed for functional second-floor spaces. Building code restrictions in your area might also limit conversion possibilities, particularly in historic districts or homes with specific architectural designations.
Begin with professional assessments from both an architect and a structural engineer who will evaluate your home's specific characteristics. They'll examine existing framing, measure available headroom, assess load-bearing capacity, and identify potential obstacles like HVAC ducts or plumbing vents.
These experts will also review local building codes to determine feasibility. Their preliminary analysis provides crucial information about structural requirements and potential limitations before you commit to the project.
Whether you'll need temporary housing depends on several factors, including the project's scope and your tolerance for construction disruption. Major structural work creates significant noise, dust, and potential utility interruptions that many families find challenging to live with. Safety concerns may also arise during certain construction phases.
Some homeowners successfully remain by isolating the construction zone and establishing clear work schedules. Discuss living arrangements with your contractor early in the planning process to make informed decisions.
