What Termite Damage Looks Like: Early Signs Alabama Homeowners Miss

Almost no one finds termite damage by seeing termites. They find it because a door that always closed fine now sticks in the frame, or the paint on a window sill bubbled, or a vacuum cleaner went through a baseboard. Subterranean termites — the ones in nearly every Alabama county — eat wood from the inside out and leave the surface intact, so by the time the surface fails, the damage behind it is usually well along. Knowing what the early signs look like, and where to look for them, is how a homeowner catches it while it is still a small repair.

The signs, in the order homeowners usually notice them

Doors and windows that stick

Often the very first sign, and almost always misread as humidity. Termites eating a door jamb or a window frame produce moisture as they work, and that moisture swells the wood. A door that rubs at the latch side, or a double-hung window that suddenly binds, is worth a close look at the frame — especially if it is a bathroom, a laundry room, or an exterior door on a slab.

Blistered or bubbling paint

Termites working just behind a painted surface push moisture into it, and the paint lifts in blisters or peels in a way that looks like a slow water leak. On a wall or trim with no plumbing behind it and no roof above it, that is a termite sign until proven otherwise.

Wood that sounds hollow or dents

Tap along baseboards, door trim, window sills, and the bottom of door frames with a screwdriver handle. Sound wood has a solid thunk; termite-eaten wood sounds papery or hollow. Press a thumbnail or the tip of the screwdriver into a suspect spot — a thin painted skin over an empty gallery gives way with almost no pressure. The classic discovery is a baseboard that crumbles when a piece of furniture is moved.

Sagging or spongy floors

In a crawlspace house — most of the older housing stock in Homewood, Mountain Brook, and old Alexander City — termites reach the floor system through the piers and the sill plate. A soft spot in the floor near a bathroom, a dip along an exterior wall, or laminate that buckled up in a line is often the first sign of a damaged sill or joist below. On a slab house, the same appears as a soft spot at the base of a wall where a stud bottom plate has been eaten.

Mud tubes

The one sign that is unambiguous. Subterranean termites build pencil-width tubes of soil and saliva to travel between the ground and the wood without drying out. Look for them on the outside of the foundation, on crawlspace piers and walls, on the inside of the foundation wall in a basement, up the side of a bath trap or a plumbing penetration, and on the framing where a deck or porch attaches. A tube running up a pier is a colony feeding on the house right now. Do not knock it down — leave it for the inspector.

Discarded wings

A small pile of identical, translucent wings on a windowsill, in a spider web, or in a light fixture in late winter or spring. The swarm itself happens in minutes and is easy to miss; the wings stay. Indoors, this means the colony is in or under the house.

Tight, dark lines and pinholes in drywall

Termites eating the paper on drywall leave faint, meandering lines just under the paint, sometimes with tiny pinholes where they broke through and then plugged the hole with soil. Look low on walls, near the floor, and around window and door openings.

Termite damage or water damage?

They overlap, and termites are drawn to wet wood in the first place, so a house can have both. A few tells:

• Galleries. Cut into termite-damaged wood and it is honeycombed with layered tunnels running along the grain, often packed with dried mud. Rotted wood is soft and crumbly through and through, without the tunnel structure.
• Mud. Termite galleries and tubes contain soil. Water damage does not.
• Location. Water damage tracks a source — a roof leak, a window, a plumbing line. Termite damage tracks the ground: it starts low and works up, worst at sill plates, bottom plates, door thresholds, and pier tops.
• Frass. Small piles of dry, sand-like pellets below a hole in wood are drywood termite droppings — uncommon in Alabama. Subterranean termites do not leave frass; they leave mud.

When in doubt, it does not matter which one it is: both need a licensed inspector, and the free WDO inspection identifies both.

Where to check first in an Alabama house

1. The bath trap. The plumbing access under a slab-house bathtub is an open path from the soil to the framing, and it is the single most common termite entry point in slab construction across Hoover, Madison, and every subdivision built since the seventies.
2. Crawlspace piers and sill plates. With a flashlight, from the access door, look for tubes on every pier and along the sill where the house sits on the foundation.
3. Exterior door frames and garage door jambs. Wood in contact with a slab or a stoop.
4. Deck and porch ledger boards. Where the deck bolts to the house, especially if the deck posts sit in or near soil.
5. Window sills on the ground floor, particularly on the shaded, damp side of the house.
6. Anywhere wood touches soil. Fence posts against the house, lattice, a wood stoop, mulch piled above the slab line, siding that runs into the dirt.

What to do when you find something

Photograph it, leave it undisturbed, and schedule a WDO inspection. Termite damage is slow — a colony takes years, not weeks, to do serious harm — so there is time to get a proper inspection rather than a rushed decision. Do not spray the tube or tear out the trim; both destroy the evidence the inspector needs to judge how active and how extensive the problem is. Our inspection is free, and it is the same inspection that produces the WDO letter a home sale requires.

If treatment is needed, the Sentricon® Always Active™ bait system protects the structure with in-ground stations and no drilling, and qualifying homes on an EnviroCare protection agreement carry up to $1,000,000 in damage repair coverage, subject to the terms of the agreement. That is the difference between finding termite damage on a protected house and an unprotected one: on a protected house, the repair is covered.

The house you have not looked at

The most expensive termite damage we see is in houses that had no signs anyone noticed, because no one was looking. An annual inspection is what turns "we never had a problem" into a fact instead of a hope. If it has been more than a year, let us take a look.
