Claim This BusinessAbout Star Insulation
Star Insulation operates out of Lowell, Massachusetts, delivering residential and commercial insulation solutions throughout Greater Lowell and the surrounding Middlesex County corridor. The company holds a perfect 5.00-star average across seven customer reviews, a clean record that reflects consistent execution on every project the crew takes on. Star Insulation's portfolio spans multiple material categories including blown-in, fiberglass batts, spray foam, and Roxul mineral wool products, giving the team flexibility to recommend the right insulation strategy for each structure rather than defaulting to a single material preference.
Star Insulation offers closed-cell and open-cell spray foam applications, tailoring density and air-sealing performance to the specific area being insulated. The company maintains a straightforward scheduling process, getting homeowners a written estimate quickly after the initial consultation so decisions move forward without drawn-out delays. Jason Byrne's review notes the crew completed his addition insulation after the space had been gutted to bare studs, and one of Star's foremen returned the following morning to spot-spray thin areas around window and door framing without being asked twice.
Four customers awarded Star Insulation five stars, with two reviews specifically crediting the crew for going beyond the contracted scope. Jeff Ferro describes closed-cell spray foam applied to his basement walls and open-cell filling the rim joists, calling the basement 'very well insulated.' A reviewer identifying as the Carrera Team mentions having worked with Star Insulation for over five years, repeatedly calling the company back for additional projects. Terezinha Vaz highlights both the quality of the insulation work and the crew's cleanup after the job, reinforcing that Star Insulation leaves occupied homes tidy.
What Customers Say
All four reviewers awarded five stars, giving Star Insulation a perfect 5.00-star average across the full set. Jeff Ferro, Jason Byrne, and the Carrera Team specifically praised the application technique and material selection, while Terezinha Vaz called out the crew's cleanup discipline. Three reviews mention follow-up attention from the foreman or crew, suggesting this level of care is a pattern rather than an exception.
