Carpet & Subfloor Prep in Tomball, TX

Carpet in the older part of Tomball raises a question that does not come up in slab houses at all: what is happening underneath it. In a pier-and-beam home the floor assembly sits over a ventilated crawlspace open to ground moisture, and carpet with a standard pad over that assembly acts as an insulating blanket. Moisture rising through the subfloor reaches the underside of the pad, cannot escape upward through the carpet quickly, and condenses. Over a few years that produces musty odour, and in the worst cases it degrades the subfloor itself.

The fix is not a better carpet. It is a ground vapor barrier in the crawlspace — heavy polyethylene laid over the soil — plus adequate ventilation. That is not flooring work and we will raise it anyway, because installing new carpet over an unaddressed crawlspace in one of these houses is putting good material into a bad environment. It is the same conversation we have about wood floors here, for the same underlying reason.

The second practical issue is tack strip. Fastening into original board subfloor is generally fine where the boards are sound, but around the perimeter of rooms in a hundred-year-old house we routinely find sections that have been cut for plumbing or previous repairs and never properly patched. Those want addressing before the strip goes down, otherwise the carpet releases at exactly the spot where it is most visible and most likely to trip somebody.
