Local homes

Hopkinton housing and climate

Hopkinton's homes range from older houses near the town common, where the Boston Marathon begins, to newer subdivisions near Hopkinton State Park and Lake Maspenock. Many newer homes have large open attics and bonus rooms where better air sealing makes a noticeable difference.

In western Middlesex County, many homes were built during the post-war and 1980s building booms, and their original insulation has settled over the decades.

Newer homes often have decent wall insulation but thin attics, leaky rim joists and cold rooms over garages, and those are the areas we target first.
