Crawl Space Radon Mitigation in Dallas, TX
Typical cost: $1,800 – $3,500 by crawl space size and condition
Dallas's most charming housing stock — the Tudors of the M Streets, Lakewood's cottages, the pier-and-beam neighborhoods of East Dallas and Oak Cliff — sits over crawl spaces, and crawl spaces change the radon equation. Soil gas rises off the open dirt under the house and finds its way up through the floor system; the ventilation that is supposed to flush it works some seasons and not others. When a pier-and-beam home tests elevated, the fix is different from slab work, and hiring someone who knows the difference matters.
The method is sub-membrane depressurization: the crawl space floor sealed under a heavy-gauge membrane, sealed at piers and perimeter, with the mitigation fan drawing from beneath it — turning the whole under-floor area into a controlled collection layer instead of an open radon reservoir. The same project usually leaves the crawl space dramatically drier and cleaner than we found it, which the floors above notice too.
Slab-on-grade additions attached to pier-and-beam originals — a classic Dallas remodel story — get hybrid systems, one fan serving both foundation types where the diagnostics allow. It is exactly the kind of house where a cookie-cutter installer guesses; the sub-slab and crawl diagnostics mean we do not.
Sub-membrane depressurization - and a crawl space left drier and cleaner than we found it.
