Penguin Insulation

Penguin Insulation operates as a full-service insulation contractor serving Lewisville, Texas and the greater Dallas-Fort Worth metroplex. The company maintains a near-perfect 4.9-star rating from 119 customer reviews, reflecting consistent delivery of quality workmanship. Specializing in residential insulation projects, the team handles attics, garages, and walls, removing old insulation and installing fresh materials to improve energy efficiency and indoor comfort. The contractor operates around the clock seven days a week, with availability extending to Sunday evening hours.

What distinguishes Penguin Insulation from typical insulation contractors is their comprehensive approach to attic performance. The crew installs solar-powered attic fans alongside new insulation, creating a dual system that actively vents heat during Texas summers. Reviewers note the team handles full removal of outdated insulation, sanitizes the attic space, and seals areas to prevent contamination. The crew also assists homeowners in coordinating drywall repairs after wall insulation projects, completing a true start-to-finish service that many competitors do not offer.

Several reviewers specifically name Alex, the foreman, for exceptional service. Jon praised Alex and his crew for solving temperature problems in his home office located above the garage, removing old insulation, adding a thicker layer, and installing a solar attic fan. Bill mentions Alex and installer Johnny accommodated his schedule and delivered neat results blowing insulation over his garage. Tony Geeslin credits Alex's team with completely removing old insulation, sealing the space, and sanitizing before the summer heat arrived.
