Termite-Damaged Trim: Who Fixes What

You notice a little pile of what looks like coarse sand on a window sill, or a section of fascia that crumbles when the ladder touches it, or a pattern of channels under peeling paint on an eave. The next question is usually: do I call a painter or an exterminator?

Often both. The question that matters is which one goes first, and where the line between them sits.

What termite damage looks like on painted wood

Termites eat wood from the inside, so the paint often looks fine long after the board behind it has been hollowed out. The signs tend to be indirect:

• Small pellets collecting below a board, on a sill or on the ground. They are hard, tiny, and under a magnifying glass have ridged, six-sided shapes. This is the typical sign of drywood termites, which are common in Southern California.
• Tiny round holes in the wood or paint where those pellets were pushed out.
• Paint that blisters or ripples over a board that sounds hollow when tapped.
• Mud tubes running up a foundation, stucco or a post from the soil. These belong to subterranean termites.
• Wood that breaks open to show clean, smooth galleries, or galleries packed with soil.
• Discarded wings near windows or light fixtures after a swarm.

On a San Diego home, the wood that shows it most is the exposed wood: fascia boards, barge boards and rafter tails at the eaves, window and door trim, wood posts, patio covers and the bottom edges of wood siding. Older homes in La Mesa and the city’s established neighborhoods often have the most exposed wood, and hillside and tree-shaded lots such as many in Bonita have their own reasons for keeping it damp.

What does pest control handle?

Finding, identifying and treating termites is licensed pest control work in California, regulated by the Structural Pest Control Board, and it is a separate trade from painting. Many of those companies also make the structural repairs their own report calls for. A pest control company inspects the house, identifies which termite it is, judges how widespread it is and recommends a treatment, whether that is a local treatment of specific boards or a whole-structure fumigation under a tent.

Their inspection report separates the infestation or damage that is evident from conditions likely to invite it later, such as wood in contact with soil or excess moisture. That report is useful for the painting estimate too, because it tells everyone which boards are affected.

A painter cannot tell you whether termites are still active, cannot treat them and should not try.

What does the painter handle?

Once the pest work is done, the damage left behind is repair and preparation, and that is where Ebenezer comes in. During the repair check that follows the power wash, he goes over the exposed wood board by board.

• Probing and opening up damaged areas to find where sound wood begins.
• Small damage is cut back and filled with an exterior wood repair material, then shaped to the profile of the board.
• Larger damage means replacing the section, or the whole board: a length of fascia, a piece of window trim, a barge board end.
• Priming new wood, ideally on all sides before it goes up, so its back and ends are protected too.
• Caulking the joints that should be sealed, so cracks and gaps are closed.
• Painting the repaired wood so it matches the rest of the house.

There is a boundary on his side too. Ebenezer repairs damaged trim and then paints it. If the damage goes past trim and into the structure, such as rafters, posts that carry load, sill plates or framing, he will say so plainly: that belongs to another trade.

Why the order matters

The sequence is short, and getting it backwards is how good work gets thrown away.

1. Inspection by a licensed pest control company. Ask for the report.
2. Treatment. Local or whole-house, as they recommend.
3. Repair estimate. Ebenezer walks the house with the report in hand and explains what each repair involves.
4. Wash, repair, mask, paint. The normal exterior sequence, with the termite repairs inside the repair step.

If the painting happens first, two things can go wrong. A tent and the work around it can scuff or damage fresh paint, especially at the roofline. And any repair made over an active colony is new food for the same termites.

Does paint stop termites?

Not on its own. A sound paint film helps, because drywood termites tend to enter through cracks, open joints and bare end grain, and paint closes many of those. Keeping fascia, trim and siding properly painted, caulked and free of soil contact is part of what makes a house less inviting. But paint is maintenance after the pest work. It is not a treatment, and it does nothing for termites already inside the wood.

What to bring to the estimate

If you have a pest control report, have it ready. It tells Ebenezer which boards were flagged and whether treatment has already happened. If you do not have one and he sees signs of termites during the walk-around, he will tell you what he sees and suggest you have the house inspected before the painting begins.

That is the kind of clarity his stucco, drywall and wood repair work is built on: what is included, what is not, and in what order. You can read more about homes in La Mesa and Bonita on their city pages.

If termite work is done or scheduled and the trim needs bringing back, ask for a free estimate. Ebenezer will walk each board with you and explain what can be repaired, what should be replaced and how it will look when it is painted.
