"With so many scams these days, it is hard to trust people. You can 100 percent trust Scott and his team. From the beginning of the process, Scott and his team surpassed my very high expectations. Scottâ s communication is clear and prompt. His prices are reasonable and payment method is easy. His experience working in the county facilitated getting permits approved. His team of contractors are professional, clean and timely. I appreciated that Scott himself managed my construction. When I wanted to change something, Scott would tell me the implications and then, if I still wanted to go forward, worked with me to make that change happen. When we discovered some unfortunate surprise inside the walls of my house or something went wrong (eg. New window delivered broken), Scott and his team made it right every time. Scottâ s honesty, flexibility, and professional expertise made working with him and his team a sincere pleasure. My experience was so good, I am saving money for my next project with Apollo!"

"Seddik and his crew did great work on my house addition. The constant communication and attention to detail made the evolution stress-free. We were able to move back in a week earlier than initially quoted and the final cost was within a few percent of the estimate, mostly due to additional touches we added on during the build. He was also extremely responsive to any issues that popped up after the job was finished to make sure everything turned out exactly like our family wanted.

"I would HIGHLY recommend US builders for any home remodeling project. I saw the quality of their work when they did a total kitchen remodel for my neighbor. The quality was top notch so I hired them to repair the outside and inside of my home when a car, traveling at a high rate of speed crashed into the front of our home. Workmanship is superb, they arrive on time, have the skills and resources to do the job, and they clean up at the end of every day. They same workers were at the job site start to finish, they could easily problem solve unique issues. They repaired and painted drywall, put on new siding and new windows, replaced ceramic tile in the foyer, and "sistered" support beams around the stairwell. PLUS they worked seamlessly with the insurance company!!!!"

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.
