Aging Housing Stock — Median Built 1959
1959
Median construction year
Chester's median construction year of 1959 means original galvanized supply lines that corrode from the inside out, cast iron drain pipes well past their service life, plaster-and-lath walls that retain moisture far longer than modern drywall, and vented crawl spaces with degraded or missing vapor barriers. When water enters these older systems, it penetrates deeper, travels farther, and dries slower than in any post-1980 construction. A leak in a Chester home from the 1950s isn't the same event as a leak in a modern Woodhaven build.
