RadonSeal

RadonSeal Market Overview

RadonSeal, a brand of the privately held Novion Inc., generated the majority of its year-to-date revenue through Amazon, which accounted for 62.3% of sales, according to in-store data from Grips Intelligence covering January 1 through July 31, 2026. The remainder was split almost evenly between lowes.com at 18.9% and homedepot.com at 18.8%, pointing to a balanced secondary retail footprint across the two largest US home improvement chains. Revenue softened over the May-July window, falling 9.7% month-over-month and 23.0% across the tracked period. Pricing moved in the opposite direction, with the average selling price rising 3.2% month-over-month to $180.70 and gaining 2.0% overall against a year-to-date average of $173.55. The divergence between rising prices and declining revenue suggests volume pressure rather than discounting is driving the recent trend.
