"I couldn't ask for a better company or result for my bathroom remodel. It started with my first meeting with Eli, who was very professional, concise and forthright in his presentation to me. It was my third estimate for the project, but.my decision was clear after meeting Eli. I love my new bathroom. The workers were excellent and always left everything neat after each day. The job was completed in 7 days, sooner than projected. Eli helped me with some of the tile choices and was patient when I asked many questions. Thank you so much, Eli"

"We recently had our bathroom remodeled by Be Home Remodeling, and I just wanted to share how happy we are with everything. Pouria, our project manager, was great — super organized, always kept us updated, and really listened to any concerns we had. Any time we needed something or had a question, he handled it right away. The crew (Manuel, Isaí )did an awesome job. They worked cleanly, were respectful of our home, and the quality of the work shows. The bathroom turned out even better than we expected, and we honestly love how everything came out. Overall, it was a really smooth experience, and we’d definitely recommend Be Home Remodeling and Pouria if you’re planning a remodel."

"Choosing Rose Remodeling & Design Inc. for a bathroom remodeling job turned out to be a regrettable decision. The workmanship lacked attention to detail, with noticeable flaws in tile alignment and fixture installation. Follow-ups regarding corrections were delayed, and scheduling became unpredictable. Costs increased without clear explanations, which created concerns about transparency. The finished bathroom did not reflect the professional standards that were advertised. Based on this experience, the service did not provide the value or reliability that was expected."

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