"I have delt with a lot of bad contractors in my life and Colbyco is the absolute worst! The communication between father and son was horrible. I was supposed to work with the father and he didn't share with the son what I wanted to happen. He lives on the other side of the state and was trying to direct the project from there which was a joke. Everything that could go wrong did go wrong and two years later I'm still living with the horrible work that they did. If you don't have any idea about what you want and leave everything in their hands then fine, but if you want something custom, to your own specifications, forget it. They will do whatever they want and won't fix it later. Run, Run, Run away from this company!"

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.
