Housing in Denison and where water damage starts
Denison has about 11,397 homes, and half of them were built in 1967 or earlier. The city added roughly 1,987 residents between 2020 and 2024 (8.1%), so a large share of homes are recent builds. With 66% of the housing stock dating from before 1980, many homes are now running on original or decades-old supply lines, water heaters, drain lines and roof assemblies. Older plumbing is a common starting point for slow hidden leaks and sudden failures, so moisture can be behind walls or under floors before anyone notices.
