"Randy was nothing but honest and professional. While installing a large, picture size sliding window in my dining room. Randy accidentally broke one of the aprons. He immediately notified my son who was working from home. He next put a call in to me at work. Randy explained and apologized for what happened and had already placed an expedited order to Harvey windows. Randy also had a lot of interior and exterior work to do, everything is completed and honestly could not be happier! Randy will be returning to do some more updates in my home in the next six months to a year. Prices are extremely reasonable with quality workmanship. He will not disappoint you!"

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.
