Home Insulation & Energy Audits in Berwick, ME

Berwick's residential mix runs from older farmhouses and colonial-era homes to newer subdivisions built in the 1990s and 2000s. Both types carry energy efficiency challenges, just different ones. Older homes lack insulation and air barriers. Newer homes often have insulation installed incorrectly or air sealing that was skipped during construction.

From the older village center to newer neighborhoods off Route 4 and Route 9, Berwick homes are a reliable cross-section of what energy auditors find across rural southern Maine.

Berwick homeowners are sometimes surprised to learn newer homes can have worse energy performance than older ones if the construction crew cut corners on air sealing.
