HONEYCOMB CONSTRUCTION is dedicated to providing our customers with the best quality and craftsmanship. We are here to build relationships with our customers and communities and to provide our employees with a great place to work.

Our pledge is to create successful relationships with our customers, employees and community by building trust, treating every project with the utmost integrity and exceeding expectations. We look forward to working with you!

"Honeycomb helped save our house. As they were replacing our deck, they discovered rot and quickly removed and replaced all the bad material. They also discovered that we had a termite infestation. The issue was in the structure of the house. They assured us everything would be fine and efficiently dispatched all the rot and talked us through next steps with detailed recommendations, involving other contractors. The additional charge to remove the rot was minimal and I would have gladly paid 10x for the security of having a safe house. And just look at how beautifully it turned out. The photos really don't do it justice, when you get to sit out there enjoying a coffee in the morning or actually having a family gathering. It is such a game changer meeting space. Also, and it might seem like a little thing, but its the details that matter. It was really hard for me to get on my deck as a physically handicapped person. Taylor made it easy for me to go outside alone. I love you guys 11/10"

"Because we were going away for an extended time, and insulation work by others had to be completed first, we had to schedule drywall workday NH Projects under a rather tight time frame. Despite uncooperative weather (lots of rain slowing the drying time), they managed to get everything done as needed, working around other scheduled work they had. They were prompt, professional, and a pleasure to interact with, in addition to doing excellent work."

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.
