Claim This BusinessAbout Thermo S Insulation
Thermo S Insulation operates as a respected insulation contractor serving Mesa, Tempe, and the broader Greater Phoenix area. The company has earned a 4.9-star average rating across 612 client reviews, a volume that reflects steady demand in this desert climate where attic insulation directly impacts energy bills during summer temperatures exceeding 110 degrees. Homeowners in Gilbert, Chandler, and surrounding East Valley neighborhoods have turned to this crew for both new construction insulation and retrofit projects in existing homes.
What distinguishes this contractor is their comprehensive approach to thermal envelope performance. They pair insulation installation with duct sealing, a pairing that addresses a common failure point in Phoenix-area homes where leaky ductwork can waste 20% or more of heating and cooling capacity. Their service menu includes spray foam, cellulose, fiberglass batt, and radiant barrier options, allowing recommendations tailored to specific ceiling configurations and budget considerations. The crew also performs home energy audits, helping homeowners understand exactly where thermal losses occur before committing to insulation upgrades.
Customer reviews repeatedly mention estimator Caden for his thorough assessments and clear pricing breakdowns, with multiple reviewers noting he took time to explain what work involved and why. For one homeowner, a crew including Raffa, Talin, and manager Darwin arrived at 6:30 AM and completed duct sealing, full insulation replacement, and rooftop vent work before noon. Another review credits the office staff Arianna and Dena for responsive communication throughout larger projects. The crew members Dylan, Ricardo, Jesus, and Andres earned specific praise for leaving work areas clean and for respectful treatment of the home.
What Customers Say
All twelve sampled reviews carry 5-star ratings. Reviewers consistently mention the estimator Caden by name and note clear communication about scope and pricing. Multiple customers specifically mention the crew arriving on time or early, with one noting completion before noon for a full-day project scope.
