Upgrading insulation in Liberty Lake
Liberty Lake is mostly newer construction, built since the 1990s, often two-story homes with large attics whose builder-grade insulation has already settled. Heat escaping into the attic melts snow on the roof, which refreezes at the eaves as ice dams; good insulation and air sealing are the fix.
Anywhere in Liberty Lake, including Legacy Ridge, Meadowwood, Rocky Hill and the River District, we remove what's there, seal the gaps around lights, pipes and the attic hatch, and install new insulation to the right R-value.

What we see in Liberty Lake homes
- The weather
Close to the Idaho line and the foothills, Liberty Lake gets a little more snow than Spokane, and long cold spells test every attic and duct run.
- The wildlife
Homes back onto the lake, the Spokane River trail, golf courses and the forested hills of Liberty Lake Regional Park, so mice and other critters are never far away.
- Under the floor
Newer Liberty Lake homes sit over crawl spaces or basements where long duct runs and builder-grade vapor barriers are easy to overlook.

“Joey and his crew arrived on time. They were very professional and considerate to our needs. We needed our old insulation swapped out and have our attic and crawl space rodent proofed. They did an amazing job at doing so. He was considerate enough to take pictures of all work completed and presented me everything.”
“This company has done a unrivaled job. They stand behind their reputation and are true to their word. They did insulation clean up, installing new insulation, sanitized and rodent proof. It's only been a few days but you can already tell the different in the temperature of our house!”
“I was super impressed with the team that came a took care of what appeared to be a nightmare attic. The team lined our floors and walls from the entrance of the house to the attic trap door, removed all the old insulation and debris, then cleaned and sanitized the whole attic, covered any openings to prevent rodents in the future and closed off any ceiling openings with foam around each of our recessed lights.…”
