Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade, combined with ability, is what makes us true professionals. Above all, we are watchful of our customers' interests and make their concerns the basis of our business.
"It is never an easy experience when damage occurs in one's home. Even less fun when it is a rental property and you have tenants there. Our kitchen flooded and after several weeks of demolition, water and asbestos abatement work, we were ready to find a contractor to jump in and put things back together. Diego and his team from Bay Quality has been AMAZING! While it turned out that he was on the lower side of all of the estimates, that was not why we chose him and his company. We chose him because he is a problem solver. Building new vs reconstruction takes a different approach. Of the 3 contractors I spoke with, Diego impressed me with his willingness to find solutions. I got a sense from other reviews that he would work quickly. In less than two weeks, he had the kitchen back together with new cabinets, countertops, flooring and appliances. He was flexible, communicative, prompt and an absolute pleasure to work with. If you're looking for a contractor for your next project,"

Addition to existing structure building services FAQs
How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.
Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
