"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."

"Nick and Steven were great! They were on time and ready to go when Nick said they would be there. The job took all day (which is what he said it would take) and they cleaned up when they were done. Very good work and a good price. I do recommend Nick's Drywall...."

"I contacted Osvaldo to repair drywall in my ceiling after water damage, and I couldn’t be more pleased with the results. From the start, they were professional, responsive, and punctual. They quickly assessed the damage, explained the repair process clearly, and gave me a fair and transparent estimate. The quality of the work was outstanding. The ceiling looks like new—seamless and perfectly blended with the surrounding area.They were meticulous with cleanup too, leaving the space spotless when they finished. It’s clear they take pride in their work and care about customer satisfaction. I highly recommend Osvaldo to anyone in need of drywall repair. I’ll definitely be calling them again for future projects!"

The typical cost range is from about $400 to $6,000, which includes materials and labor.

And for standard attics, loose-fill, spray foam, or blown-in insulation work well.
