Weatherization Services LLC

Weatherization Services LLC operates from Greenfield, Wisconsin, specializing in residential insulation solutions for homeowners throughout the greater Milwaukee metropolitan area. The contractor holds a 4.8-star rating compiled from 316 customer reviews, reflecting consistent quality in attic insulation, air sealing, and energy efficiency upgrades. Service offerings include new insulation installation, retrofit projects, and specialized attic door construction with integrated insulation and sealing. The company maintains standard business hours Monday through Friday and provides project estimates through their office staff.

This insulation contractor distinguishes itself through comprehensive energy incentive handling. Staff members process Focus on Energy credits directly on customer bills rather than requiring homeowners to submit separate rebate applications and wait for check delivery. The team also assists customers with tax refund documentation for qualifying efficiency upgrades. Each project begins with diagnostic heat gun imaging to identify heat loss zones, and technicians document work with before-and-after photography. Project preparation includes extensive tarping and surface protection, with crews committing to leaving residences cleaner than arrival conditions.

Customer reviews highlight specific technicians who deliver detailed project explanations. Francisco provides estimates and conducts follow-up visits to address homeowner questions. Luis leads installation crews that arrive at scheduled times and work through completion without early departure. Reviewers note crews constructed a custom insulated attic door with approximately 10 inches of insulation and complete sealing. One customer specifically credited the team for restoring warmth to their home during the week of their first child's birth.
