"We recently hired Illinois Insulators in Downers Grove, Illinois, for insulation and mold remediation, and we couldn't be more impressed with the results. From start to finish, their team led by John was professional, thorough, and highly knowledgeable. They took the time to explain the entire process, answered all our questions and addressed all our concerns. The insulation work was completed efficiently and with great attention to detail. We noticed an improvement in comfort almost immediately. Their mold remediation services were equally outstanding--meticulous, safe, and effective. They addressed the issue at its source and left the space spotless and healthy. What stood out most was the team's courtesy and respect for our home. They arrived on time, worked cleanly, and treated the job with true care and expertise, and afterwards left our home as spotless as it was before they started. It's rare to find a company that combines quality workmanship with outstanding customer service, but Illinois Insulators delivered on all fronts. We highly recommend them to anyone needing insulation or mold remediation. Exceptional work and a great experience from beginning to end!"
