Insulation Specialists Inc.

Insulation Specialists Inc. is a family-owned insulation contractor based in Butler, Wisconsin, serving Southeastern Wisconsin and Northern Illinois. The business holds Corbond Dealer License #011 and maintains a 5.0-star rating from 19 reviews, reflecting consistent customer satisfaction across residential, commercial, and light industrial projects. Founded in 1995 by President and CEO James Maas, the company emphasizes doing the job correctly the first time, a principle that has driven steady growth over the decades.

The contractor differentiates itself through branded product partnerships with Corbond and Champion Insulation, both recognized for energy efficiency and safety. Unlike contractors who quote flat rates, Insulation Specialists breaks down quotes by area, allowing homeowners to select specific insulation zones within their budget. Reviewers consistently note the crews attention to masking and draping surrounding areas before spray foam application, followed by thorough cleanup, demonstrating a detail-oriented approach that many customers specifically appreciate.

Customer reviews highlight specific technicians by name. Jim Maas, Luis, and Dan received praise for recommending vapor barriers during a flood restoration project while coordinating with other contractors. Another reviewer described Jim working within a budget constraint, with the crew arriving promptly and properly preparing the work area before applying spray foam. A third customer mentioned frost in a closet during cold weather, for which Jim provided a free consultation explaining the cause and prevention method. These scenarios illustrate the contractors willingness to diagnose underlying issues rather than simply proposing additional services.
