Demand is driven by aging housing stock, increased severe weather events, and growing awareness among homeowners and property managers about moisture damage prevention.

Who buys these: Owner-operators from construction or trades backgrounds, private equity-backed home services roll-up platforms, strategic acquirers such as restoration companies, foundation repair firms, and general contractors seeking to expand service offerings
