Rotted Trim and Fascia: What We Find Before an Exterior Repaint
· 5 min read
Almost every North Texas exterior repaint turns up some soft wood. Here's how we identify it, when it's filled versus replaced, and why it can't be painted over.
On a typical Dallas-area exterior estimate, we expect to find rot somewhere. Fascia behind gutters, window sills, garage door jambs, and the bottoms of corner trim boards are the usual suspects — all places where water sits instead of running off.
How we find it
The test is simple: probe suspect areas with an awl. Sound wood resists; rotted wood takes the point with no effort. We walk the entire perimeter before quoting, because the difference between a paint job and a paint-plus-carpentry job matters to your budget and your schedule.
Fill or replace?
- Small, shallow damage in otherwise sound trim gets consolidated and filled with a two-part epoxy wood filler, then shaped and primed.
- Anything soft through the thickness of the board, or longer than roughly a foot, gets cut out and replaced.
- Fascia with active gutter overflow behind it gets replaced and the drainage issue flagged — filling it just delays the same repair.
Why painting over it never works
Paint is not a structural material. A coating over soft wood seals moisture in, accelerates the decay, and hides it from you until the board fails. Within a season or two you'll see the paint bubble in exactly that spot, and by then the damage has usually spread into the framing behind it.
All new and repaired wood gets primed on every face, including the cut ends and back side, before it goes up. End grain absorbs water fastest, and priming it is the single cheapest thing anyone can do to make exterior trim last.
