"We hired Jason Mallette (Mallette Quality Construction) because he was very professional and we also felt he would best build the deck we wanted - and we were right. The deck is exactly what we envisioned and will give us many years of use and then some. Once Jason got started he was present and reliable. The deck came together with hard work and skill.

"This is an honest company. I've worked with other contractors before, and there's always something; a delay, an unexpected cost, something! But not with Will and Corey. I hired them to build a small bathroom in the upstairs level of a home we purchased for our daughter. They helped us pick out the fixtures, respected our price parameters and were just all around good guys, They cleaned up everyday after themselves, arrived each day when they said they would and built a beautiful, small bathroom that we are very pleased with. You will not go wrong trusting your project with Loomis Bros."

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.
