"Nelligan Insulation replaced and topped off the insulation in our attic after water damage, and we were very pleased. Mike called ahead to schedule, came out to measure, and gave us straight answers about our existing insulation and what it would take to bring it up to current standards. His quote was fair and arrived the next morning. The crew finished the whole attic in under three hours. We would recommend Nelligan to anyone looking to improve their attic insulation."
