Gansenberg Construction

Gansenberg Construction is a family operation — Charles T and Jon Gansenberg are both listed as owners — working out of 22 Lakeshore Dr in Georgetown, with a Kingston, New Hampshire headquarters address alongside it. BuildZoom has 49 permitted projects on file for the company, and describes the work as new home construction, major additions, and whole-house, kitchen, bathroom and basement remodels. On licensing, BuildZoom lists a Massachusetts construction supervisor licence, CS-092108, and a home improvement contractor registration, 161159, both of which the directory says it checked in 2026. Those are the directory's records, not something confirmed against the state registry here, so ask to see both before signing anything. No customer reviews exist on file from any source, which is the real gap: there is a permit history but no account from anyone who hired them. For a Georgetown-area addition or remodel, treat the permit count as evidence the work gets pulled and inspected, then do the usual homework — verify the two licence numbers directly with the state, ask which address the contract is written from, and get references from recent jobs.
