Termite Infestation Can Leave the Floor Framing Weakened

Termites do not eat concrete or block, so they do not damage the foundation itself. What they damage is the wood structure that rests on the foundation and carries your floors: the sill plate on top of the foundation wall, the floor joists, the girder beams, and the wooden support posts. The eastern subterranean termite common in the Carolinas hollows these members out from the inside. When that load bearing wood is eaten through, the floor system loses support and can sag or settle even though the foundation is intact, which is why the framing gets a structural inspection.

Common signs include mud tubes running up foundation walls or piers, wood that sounds hollow when tapped or crumbles when probed, and floors that have started to sag, bounce, or slope. Doors that stick and small diagonal cracks at door and window corners can appear once weakened framing drops. Because termites hollow wood from the inside, a member can look sound on the surface while being compromised behind it, so the reliable way to gauge the structural extent is a crawl space inspection that probes the affected wood and measures how the floor above has responded.

By probing it. Termites hollow wood from the inside, so a joist or sill plate can look sound on the surface while being compromised behind it. The inspector probes each member termites reached and measures floor elevations to see how the floor system has responded. If a board is marked but still sound, we will tell you it does not need replacing.

Both come back to moisture. Subterranean termites live in the soil and are drawn to damp wood, and the same humidity that attracts them also rots framing on its own. Across the Piedmont around Charlotte, Greensboro, and the Triangle, humid summers and clay soils that hold water can keep crawl spaces damp for months, and along the coast around Wilmington and Leland a high water table keeps the ground saturated. In those conditions it is common to find termite damage and rot in the same joists and beams. That is why our inspection looks at the crawl space moisture as well as the wood.

The structural inspection is free. The inspector probes the framing termites reached, measures how the floors have responded, and checks the crawl space moisture, and you receive the findings and a written estimate at no cost before any work is scheduled.

Once a licensed pest professional has treated the colony, a HydroHelp911 inspector gets into the crawl space to find and probe the framing termites reached, identifying which joists, beams, sill plates, and posts have lost strength. We measure floor elevations to see how the floor system has responded and check the moisture conditions that allowed the problem. You receive a clear, written explanation of what is actually compromised. The inspection is free, and there is no obligation to proceed.
