Duncan sits right on the I-85 corridor — and we’re in and out of homes here all the time. Older ranches, newer subdivisions, and everything in between.
A lot of Duncan is newer than folks realize — which means the crawlspaces are often sealed but sealed badly. Builder-grade vapor barriers, undersized dehumidifiers, and vents that were never closed off properly. The end result is the same as the older homes: humidity above 65%, musty air pulling up into the house, and floors that tell you something’s off.
In the established parts of Duncan — off Hwy 290, near the old downtown — we’re usually doing first-time encapsulations. Old fiberglass insulation hanging down, no vapor barrier, open vents. Full reset. Once it’s done, homeowners notice it within a week: smells better, sounds quieter under the house, HVAC runs a little less.
In the subdivisions toward Lyman and Wellford, we spend more time diagnosing than installing. Sometimes it’s a simple fix — a dehumidifier swap, a vent seal, a patched liner. If that’s all you need, that’s all we’ll sell you. We’d rather earn the referral than stack the invoice.
Neighborhoods we work in: Hwy 290 corridor, downtown Duncan, Groce Meadow, and the subdivisions along the I-85 exits.
