Local experts
Why cellulose works so well in Hopkinton homes
Cellulose installs fast and covers large areas evenly. For Hopkinton homeowners, that usually means a one- or two-day job and a noticeable difference in comfort the first winter.
In newer homes, blown cellulose is usually added on top of the existing attic insulation to reach today's recommended depth.
Because Hopkinton is close to our Westborough office, we can usually see your property within days.
- Made largely from recycled paper

Know your Hopkinton home
Hopkinton, the starting line of the Boston Marathon, has older homes near the town center and many large colonials built since the 1990s.
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.

Can you insulate walls with knob-and-tube wiring?
