"Jim and Danielle help me take a room that was old-fashioned and in need of a remodel into a space that is very warm and inviting. With his guidance on the day-to-day work and his ideas for how to design the space, he was a valuable resource for me through the process. He gave me lots of ideas and choices from flooring to fixtures. As the crews that came into the house were friendly and considerate of my privacy as I work from home. They worked hard and completed their piece of remodel as planned. I highly recommend Jim and Danielle Katz at Casade Customer Renovations, LLC. "

"This team is top notch! We contacted a few contractors and never heard back. Once we contacted Mangone Contracting, we had a meeting at our home within a day or so and drawings within 24 hours of that meeting. We had a bedroom and bathroom added to the second floor of our home and it turned out wonderfully! Another great thing is they did it for right around what the estimate was written for. (Price and timeline) The whole team was very good at meeting our requests and even came out on a weekend (within 30 minutes of contact) to fix an issue we were having with our breaker box after putting a new service in. All around great people and great at what they do!"

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.
