"We hire Geico Builder to handle our home renovation, including updates to the kitchen and bathroom, and the whole experience was fantastic. The team was professional, organized, and easy to communicate with from start to finish. They showed great attention to detail, stayed on schedule, and made sure everything turned out exactly how we envisioned it. Our kitchen looks stunning, the new bathroom layout is so much more functional, and the bedrooms feel brand new. It's rare to find contractors who combine quality work with honesty and reliability, but Geico Builders delivered on all fronts. Highly recommend them for any home remodeling project."

"Cal Patton is THE ABSOLUTE BEST. The work he did remodeling my garage into a studio apartment was done with quality workmanship, professional care, and great communication. Now, two years later, I am adding a bathroom and had some questions. Cal answered my texts and calls immediately and, even though he had several other projects going on, he literally jumped in the car and came to advise another contractor to set him straight. (I wish Cal could be doing the bathroom addition but he was booked currently.) I highly recommend Cal. He's got your back, he is a true pro, and a great human being."

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