"I was very pleased with the blown fiberglass insulation they installed in my attic. It's a nice, clean job with quality insulation. I had 5 quotes from companies and this was by far the best value for the job."

"From the consultant, Joe, to the five men that came to my home, I was impressed with the professionalism and respect for my home. Tyler,Jake, Chuck, Dustin and Scott made sure everything was installed with exceptional precision and attention to detail. It took a full day to accomplish. They arrived on time, and cleaned up afterwards throughout my home and garage. Protective covering on their feet with additional protective materials on my floors and walls were used. Their care and respect went above and beyond. The product is eco friendly, fire retardant and mold resistant. And my home is warm and cozy. Removing all the old and filthy insulation that is 37+years old and leaving my attic space and foundation areas sealed and cleaned just makes everything feel buttoned up and tight. Highly recommend! Special shout out to Makaila and Katie, office personnel that kept in touch and applied for eligible rebates to help keep costs down as well. Thank you!"

"Bill from WBI was the first to contact us and the first to give us a quote on the insulating of the attic and crawl spaces of our old farmhouse. The price was very fair for the professional quality of work we received. Bill is a very honest, competent, hard-working professional. He got the job done very quickly, and we are beyond pleased with the work he did for us. We can't say enough good things about WBI, and we highly recommend them!"
