Insulating Washington County
Washington County has some of the highest-end residential construction in our service area. The northern half, around Forest Lake, Scandia, Hugo, May Township and Grant, is known for large wooded lots, custom homes and barndominiums with serious shops.
Further south, Stillwater's older homes often have thin attic insulation and empty or partly filled walls, where air sealing, blown-in attic insulation and dense-pack sidewall insulation make the biggest difference.
Common projects in Washington County
- High-end custom homes and barndominiums on acreage

FAQ
Washington County questions
Can you insulate the walls of an older Stillwater home without removing plaster?
Usually, yes. Dense-pack cellulose goes into each wall cavity through small holes, typically from the outside behind a removed course of siding, so plaster and trim stay in place. Old knob-and-tube wiring has to be addressed by an electrician first.
