"Let me first start off by saying Jon and his team at Coastline Construction are top tier. I put an inquiry into Angi's list and Jon showed up the next day, talked to me about specifics and gave me a timeline I could expect, his quote was very reasonable (lower than others as well) and he stayed within budget. My roofing work came out fantastic and I would recommend this crew to anyone looking to have work done on their homes or businesses. Thanks Jon!"

"Bought my first house with my wife and like most first houses it was a fixer upper, I wasn’t comfortable doing the projects myself just due to the nature of them so through an acquaintance I got a hold of Maine project management and the rest is history. The professionalism was top tier and although I was new to this they took the time to guide me through the process and made sure I fully understood the renovation process. 10/10 highly recommend "

"He consistently was behind schedule, had several hidden costs, poor finish work, blamed others for any issues that came up. Would not stand behind mistakes made by his subcontractors.

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.
