A-1 Radon & Vacuum carries a 4.9-star rating across 245 Google reviews, which matters in Appleton where moisture is a constant concern. With 70% average humidity and 30 inches of annual rainfall, homes here - especially the median built in 1971 - are prone to mold problems. A contractor with that track record suggests they understand the specific challenges older Appleton houses face and deliver results homeowners trust enough to review positively.
Before hiring, verify that your contractor holds IICRC S520 certification, since Wisconsin doesn't require a specific mold remediation license. You should also confirm they're registered as a dwelling contractor with the Wisconsin DSPS. Budget $1,200 to $3,750 for a typical remediation project in this area, and get a detailed estimate upfront so there are no surprises about scope or cost.
