The Moisture Is Below the Surface, Not in the Carpet
Wet carpet smell that lingers for more than a day or two after a water event means the carpet surface dried while the padding and subfloor below it remained wet. In the Las Vegas climate, carpet surfaces dry quickly from the dry air. The padding below, the tack strip at the edges, and the subfloor or concrete slab underneath do not dry at the same rate. Wet padding holds moisture against the subfloor and feeds mold growth from below the carpet surface.
A property manager in North Las Vegas had us assess a unit where a washing machine had overflowed two weeks prior. The carpet was replaced immediately after the event. The smell developed under the new carpet within ten days. We found the concrete slab still at elevated moisture content the water had penetrated and was still present below what was replaced.
Why Replacing the Carpet Does Not Always Solve It
If the subfloor or concrete slab absorbed water during the event and was not professionally dried before new carpet was installed, the smell returns because the moisture source is still there. Commercial structural drying equipment is required to extract moisture from the slab and subfloor. Replacing surface materials without drying the assembly beneath them does not eliminate the source.
What We Do
We use moisture meters that measure to depth, not just surface readings. Thermal imaging shows us where moisture is retained below the surface. Commercial drying equipment removes it to IICRC S500 target moisture content, verified by daily readings. If mold has already established in the wet materials, remediation is part of the scope.
