"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"

"Updating our home was a dream we have had for years. But finding a good contractor in Bay Area was so difficult, that we almost gave up. We were introduced to United C Construction by our architect(who we also love!) It was exhausting trying to find someone trustworthy and not overpriced. We had luck of working with Osmar which during the project we had clear communication, expectation of setting, professionalism and superior craftsmanship. He walked us through every step of the way, and helped problem solve tough permitting and structural issues in Berkeley!"

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