Signs of Dry Rot Damage
How homeowners can identify possible dry rot and when to request a professional exterior assessment.
Warning signs of dry rot
Dry rot often starts where water sits, leaks, or cannot drain. Homeowners may notice soft trim, swelling, peeling paint, gaps at joints, staining below windows, or siding that feels loose or spongy.
Where to inspect first
Window sills, trim returns, corner boards, and horizontal ledges.
Deck ledgers, stair connections, rail posts, and wall attachments.
Areas below gutters, roof transitions, hose bibs, vents, and penetrations.
Dry rot repairs should be completed before new siding, paint, or trim hides the damaged area. VTV can open affected areas, repair the substrate, and rebuild the exterior detail so the same problem is less likely to return.
Why dry rot should not be covered up
Paint, caulk, or new siding can hide symptoms for a short time, but damaged wood and trapped moisture usually continue to spread. Repairs should remove compromised material, identify the water source, and rebuild the area with correct flashing and drainage.
When to call a contractor
Call for an exterior assessment when trim feels soft, paint fails repeatedly in the same area, siding buckles, windows show staining, or deck attachments look suspect. Early inspection can limit damage and help plan siding, window, deck, and painting work in the correct order.
