Newer homes
Homes from the 2000s growth usually need the rim joist sealed and basement walls insulated before finishing. Rooms over garages are a common cold spot.
Older homes near the center
Earlier houses may need attic air sealing, more depth and dense-pack wall insulation. We check wiring before filling walls.
A name with a story
Luxemburg and Belgium, Wisconsin, ended up with each other's intended names because of a clerical error, according to state place-name records, and both kept them. It is a short drive east of Green Bay, and we include it in our regular service area.
