"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."

"We are extremely pleased with Eli and the entire ELM team! We needed to remove and replace attic insulation after the Eaton fire and our location blocks from the canyon. Eli outlined the scope of work and answered all our questions. Alex and his crew did a very professional job of completing the difficult work efficiently and as planned. Miriam was a pleasure to work with in scheduling the work and coordinating payment. And the cost was a real value! Thank you very much for your expertise, quality work and excellent customer service.
