We offer wide variety of work , interior framing , finish work , small roof projects, siding etc….we are Wedi Certified for bathroom remodeling

"New vinyl siding, new roof, 2= 6 by 12 ft. Decks, found a loot of rot from years of water damage. It was a huge job. Due to rain & heat, ordering wrong items or not enough of the items, there were a lot of delays. In the end, we are not happy with the end results. There are many little repairs that we have to do and that is exactly why we hired out, so WE wouldn’t have to do anything."

"Basement family room remodel here. Home Possibilities was extremely professional with great attention to detail. Since it is an older home, surprises arise but Mark was able to pivot on a dime and come up with a solution without blowing the budget. Even matched door handles from a previous project. Would definitely reccommend and plan to call on Home Possibilities for our next project."

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.
