"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"

"Cunningham Construction (Paul and Vicki) helped us navigate a fairly complex remodel where we moved a laundry room to our garage and replaced the laundry with a shower creating an downstairs guest space with it's own bath and shower. Paul and Vicki adeptly managed the permitting process across our county and township. Paul's attention to detail showed through in the planning and execution. The project involved managing electrical, plumbing, painting and custom shower installation teams, drawing up architectural plans for the home, and leveraging a deep cross functional set of skills from framing, drywall, texturing, tile, door framing, procurement of materials and disposal. Their professional and detailed approach was further enhanced by their down-to-earth collaboration, explanation and high quality execution. Our project took time to get right, and the accounting for materials, labor and schedule were detailed and accurate. I would be so happy to work with them on future projects!"

"We had our two bathrooms fully remodeled by Golden View 4 years ago, and were very happy with the results. Recently we noticed a leak from the shower in one of them that was affecting the nearby flooring. Asaf and the team really came through for us, they diagnosed the problem - a shower pan leak - opened the walls to clean and mitigate mold, planned and executed a partial demolition and rebuild of the shower including an improved method for waterproofing, and restored the bathroom and walls back to original condition and full functioning. All of this and they didn’t charge us, since Asaf told us he wants to stand behind their original work and fix problems arising. Five stars for sure! "

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