"Kitchen looks good but the quality of work is disappointing. Flooring they recommended is peeling up and they did not pit caulking along a certain part of the counter. Also they charged me for an electrical panel that kept turning off my stove or garbage disposal if I turned on too many appliances. So upset that I trusted the main person."

Bay Quality Construction, Inc. is committed to excellence in every aspect of our business. We uphold a standard of integrity bound by fairness, honesty and personal responsibility. 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,"

"We couldn't be happier with the transformation Crane Construction brought to our second-story balcony. That tricky L-shape and the height had us worried, but your team handled it with such expertise. From the clear communication and detailed estimates to the flawless tile work, every step was handled professionally. We were particularly impressed with the attention to detail, especially the waterproofing and the way they tackled that unexpected structural issue ? it really showed your team's problem-solving skills. We now have a beautiful, solid balcony that we'll enjoy for years to come. Thank you and your team for the fantastic work!!!"

Ever wonder how contractors come up with their pricing? Why are prices so high? Five years ago, we had that same question. We started as real estate investors and developers. Every time we had to hire contractors, their pricing made no sense, and their approach was disorganized and random. That's when we decided to start our own contracting firm. At Hummingbird Development, we apply rational pricing, orderly processes and schedules, and a focus on quality. And because we started out as real estate developers, we always look at costs first, and don't spend our clients’ money indiscriminately. We look for ways to add high quality touches where it matters, without overspending on items that aren't necessary. We are a family business focused on helping homeowners add value without breaking the budget.

"They did excellent work and cleaned up well after themselves. Very professional."

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.
