Swanick Builders is committed to excellence in every aspect of our business. Fully insured as an LLC we uphold a standard of integrity bound by fairness, honesty, and personal responsibility. Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade combined with ability to make it happen is what sets us apart from others. Above all, we are watchful of our customers' interests, and make their concerns the basis of our business. Hope too hear from you…

"Swanick Builders were not consistent with time lines. They would make choices that we as the homeowners should have been consulted on or made. Builders made many mistakes of placement or painting wrong colors from chosen /discussed choices made by us. When talked to about this they would state its a focal point. Level of work has been found to be subpar at best, needing other professionals to come correct. Sub contractors utilized by builders were subpar putting hole in roof . all in all they should not have taken such a large job and we would not be hiring ever again. "

"Garrett and his team removed a load bearing wall for us to create a larger living room. The job required demo, architect drawings, inspection, installing LVL beams, adding recessed lights, replacing wood flooring, and drywall. The whole job took about 4-5 weeks. Garrett walked us through the whole process and was always very prompt. If he said he would show up at 9 AM, he would show up at 9 AM. He was also very upfront about our costs?no surprises. Our new living room looks great! I highly recommend Garrett for any renovations!"

"We met Dan months before the project was scheduled to start and he knew our deadline was 7/9 when our first weekly vacation renter was due to arrive. Our main issues were: He was a week late starting Didn't show up on several days (had to take his son to get his COVID shot, several days it was too hot, heavy traffic, etc) Ignored my detailed instructions/drawings and we lost time because he plumed a double vanity for only 1 sink, told us we could buy any standard shower door from Lowe's only to learn AFTER the shower had been framed that it required a custom built door, forgot to tile the accent color stripe in the shower, miscalculated the amount of shower tile needed requiring me to drive 3 hours RT to purchase extra tile and deliver it to him. Skim coat on the ceiling was done poorly, the door to the bathroom didn't open all the way so we had to hire someone after Dan left to shave it down for us. He was supposed to finish by July 9th and didn't finish until Sept 9th!!!! had to give renters $3000 off because they had no toilet or shower. I split the difference with him and took $1500 off his bill and he was not happy. I should have taken the entire amount off. He might be OK for smaller jobs, but he is not focused enough and doesn't work a full day (usually 8 AM -1 PM) or even a full week. If he takes work outside of NH, he should have his plumbing/electrical license so he doesn't have to rely on outside contractors. We suffered because he didn't hold ME licenses and wasn't well connected w/ local contractors in ME."

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.
