"After talking with several attic clean out and insulation, wall insulation companies, I decided to go with Marathon Insulation. Johnathan was very helpful and professional, gave the best choices for my issues, without trying to upsell like some of the others. After getting the attic and walls insulated (with attic clean out) I can already feel the heat stay in the rooms much longer and the walls much less cold to the touch before. I highly recommend Marathon Insulation! They were always on time, delivered as promised, and cleaned up after."

"Mr Lee was great to work with. He showed up on time and his work was terrific. Afterwards he made sure to clean up everywhere he worked so you couldn’t even tell he was here (except for the repaired work). He replaced drywall from a plumbing issue and also fixed some holes we had in drywall."
