Indoor signs of termite damage or termite activity: using a termite damage case this article series provides a detailed study of a termite inspection that found insect & rot damage.
Here we describe indoor indicators of termite activity, termit damage, or conditions inviting termite attack indoors show how to inspect for termite damage & assess extent of termite damage on a building. These photographs, inspection advice & visual clues lead to discovery of severe hidden structural damage to a building.

This disturbing case study reports a sequence of clues suggesting insect damage, then termite damage, then the discovery of very extensive hidden termite damage in a finished wood floor. We provide a sequence of photographs showing the course of our termite inspection and what we found.
A sign of trouble at this home that we had seen outdoors was siding close to, in contact with, and even below ground level at several locations that also exacerbated conditions by combining in-slope grade towards the building with roof spillage around the foundation.
So when we went inside we were on red alert for insect damage before ever entering the home.
Even in a home where a crawl space gives view of the foundation wall (photo at above left), a combination of outdoor termite invitations (soil close to siding, water against the building walls), and framing methods (no termite shields on foundation top, no treated lumber used for wall sills atop the foundation) can add up to a high risk of termite or carpenter ant attack on the structure.
Add that much of the home in this case study was constructed as concrete slab on grade or over inaccessible crawl space, and extra care was called-for.
Watch out: if you are renovating a building where there has been termite damage, be careful not to disturb and breathe in dust from chemically-contaminated wood. Find out what type of treatment was performed, by whom (was it a qualified licensed pest control company), and where.
Below right our photograph shows a beautifully-finished and "brand-new" looking floor in a family room wing. We knew that this floor was built over either a slab on grade or an inaccessible crawl area - there was no access from below. The room was described has having been recently remodeled by the owners in the course of preparing the home for sale.
But wait? What was that odd gray goop we spotted along the floor perimeter where some old flooring also remained in place? See our photo at below right.
The combination of old floor boards and wood filler and caulk shown at below right made us worry about what sort of damage had been "repaired" in this floor.
We continued looking under furniture and behind doors - see our photo at below left: there remained a collection of older oak flooring extensively patched with wood-filler.
