Valley Home Insulation LLC

The name that shows up most in Valley Home Insulation's reviews isn't a crew chief — it's Giselle, the person in the office who walks customers through the Mass Save paperwork. Across 33 Google ratings averaging 4.7, the program is half the story: the no-cost energy assessment, the application, then attic and wall insulation, air sealing, and in several cases a boiler or heat pump swap alongside it. A large share of those reviews are written in Spanish, and the Lawrence company describes its focus as weatherization for Spanish- and multi-lingual-speaking households. Customers writing in May 2026 credited Giselle and Ronald with getting the application through and called the heat pump installation crew efficient, fast and tidy. A January 2026 reviewer who had the house insulated and a boiler replaced described the same attentiveness in English. What people report afterwards is concrete. A customer writing in April 2025 said the gas bill had reached $900 before insulation and changed significantly in the first month after. A February 2025 reviewer said they now turn the heat down because the house gets so warm. A January 2025 customer described blown-in insulation in a garage ceiling and one exterior wall following an energy audit, and named both the crew and the auditor, praising the cleanup. Two caveats sit in those same reviews. That April 2025 customer also said the process took almost a year start to finish. And a September 2023 reviewer described the sharper version: after the Mass Save assessment and signed paperwork, they were ghosted, with multiple emails and calls unanswered. Nothing like it appears in the reviews written since. The permit history matches the trade. BuildZoom shows 50 projects with 25 in the past three years — attic, slope and basement-sill insulation, blown-in cellulose, rim-joist air sealing, blower-door and CAZ testing, bath fan installation — though almost all of them sit in Lowell. BuildZoom also reports that the Massachusetts license board showed a home improvement contractor licence active when it last checked; that hasn't been confirmed against the state registry here, so ask for the number. The company's own site claims Mass Save partner status, Massachusetts Home Performance Contractor standing, and certified insulation installers on staff. For a Mass Save weatherization job around Lawrence and Lowell — especially if handling the application in Spanish matters — this is a shop that treats the paperwork as seriously as the blowing. Ask for a written schedule and a named contact at the start, and confirm who performs any heating or electrical work bundled into the project.
