"What can I say about Dan and crew? If there were six stars, I would have given them all of those! Our powder room job was also flooring for the hallway and laundry room, plus a utility sink. It was a total gut job in the bathroom. Dan could not have been nicer, quoted us a more than fair price and the job was finished in record time. He was very responsive to any questions we had (ok mostly me). Also, his workers (2) were fantastic. I'm not sure if I should name them, so I won't. They were efficient and professional, asked questions when needed and cleaned up the site and their work space (our garage) every single day. They treated our home with care, as well as our old appliances and new fixtures. We could not have been happier with all of it."

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.
