Level Up Insulation was contracted by my pest control service, Saela, to mitigate a mice & rat infestation in my home's crawl space. Two technicians, Afren and Alberto, removed all the contaminated wall insulation and the ground moisture/radon barrier in the crawl space. They sanitized the crawl space, then installed new wall insulation and radon barrier over the ground. They bagged all the contaminated materials and disposed of it all without leaving a trace behind (they protected the basement living area and 1st floor hallways with plastic sheeting). Afren and Alberto were friendly and professional, and super hard-working. That job would've taken me a week, and they banged it out in half a day. The finished job looks amazing... clean, bright and fully sealed. I highly recommend Level Up Insulation, as well as Saela Pest Control.

Level Up did a good job. Protected the floors through the house and furniture in the access points. Crew was friendly. The job progressed at a good pace. My house already seems less dusty and the air just a bit crisper. The owner/manager was easy to work with and responsive.

John Riley Google review · May 2026

We had Level Up install blown in insulation in our Denver attic after our energy audit showed we were way under the recommended R-value. The team was in and out in half a day, and the difference was immediate. Our second floor used to be ten degrees warmer than the main level in summer — now it's even throughout. Great experience with the blown in insulation in our Denver attic.
