Short answer
In Greensboro, most wood rot we repair starts where water sits: behind overflowing gutters, under failed caulk, at post bases. If wood is soft now, keep weight off it, turn the water away and do not paint over it. We cut back to sound wood, fix the water path, then rebuild.
Signs it is time to call
- Paint peeling in stripsStrips lifting along a gutter line often hide wet wood.
- A screwdriver sinks inRotted wood lets the tip sink easily.
- Doors and sashes that bindA swollen jamb or sill stops doors and sashes moving.
- A gap at a column baseA crushed post base usually means rot.
How we run the job, step by step
- Probe and mapWe mark where sound wood begins.
- Find the water pathGutters, caulk, flashing and grade come first.
- Shore and removePorch roofs get temporary posts, and rot comes out.
- Rebuild and flashPrimed stock at the old profile, plus flashing.
- Caulk and paintNew wood is sealed and painted, never left bare.
Rot is slow until it isn't. A sill that takes a screwdriver tip this spring can bind a sash next year, and a porch post can look fine from the yard while hollow at the base. So we find the water source first, because new wood without that fix only resets the clock.
We probe every board around the soft spot, not only the one you pointed out, and mark cut lines before anything comes off. New stock is primed on all six faces, and joints are flashed or sloped to shed water. Where a trim profile is no longer sold, we mill it.
Fascia and soffit gone soft behind the gutter
Fascia rot shows up as paint peeling in strips along the gutter line, a gutter pulling away, or a soffit sagging at a corner. The cause is nearly always water overflowing a clogged gutter or running behind it. We take the gutter down, cut the fascia back to sound wood, check the rafter tails, replace stained soffit, and add a drip edge before the gutter is rehung. Angi's national figures put exterior and porch rot repair at $5 to $30 per square foot.
Window sills and door jambs crumbling at the bottom
The bottom corners of sills and the foot of exterior door jambs rot first, because water collects there and the paint film breaks. You notice it when a screwdriver sinks in, a storm door stops latching, or the threshold rocks. Shallow rot can be dug out and filled with epoxy; deeper rot gets a dutchman of new wood scarfed in, or a whole new sill or jamb leg. Angi lists window and door framing rot repair at $5 to $25 per square foot nationally.
Porch posts and deck boards that flex underfoot
Porch posts rot at the base, where end grain sits on a damp slab, and decking rots at board ends and over joists. If a column has a gap or crushed look at the bottom, or the floor bounces, keep people off it. We shore the porch roof with temporary posts, replace the base or the whole post, and set it on a stand-off base that keeps end grain dry. Rotted boards come out back to the nearest sound joist, and the joist tops get checked.
Siding and trim boards with rot behind the paint
Lap siding and corner boards rot from the bottom edge up, especially near grade, behind downspouts, or under a window that has been shedding water onto them for years. Bubbling paint or a cupped board is the outside sign. We remove the affected courses, check the sheathing and house wrap behind them, and install primed boards at the same exposure so the laps line up. Angi puts professional dry rot repair of about 100 square feet at $500 to $3,000 nationally.
When a DIY rot patch is enough
Digging out a shallow soft spot in a sill corner, drying it and filling it with two-part epoxy is a fair homeowner job on trim that carries no load. Porch posts and gutter-bearing fascia are different. Pulling a post without shoring can drop the porch roof, and filler over rot that reaches the framing hides the problem instead of stopping it.
Remodeling this in Greensboro houses
Rot on an older Greensboro porch can carry an extra step in College Hill, Dunleath or Fisher Park. City historic district guidelines favor repairing original material, replacing rotted siding or trim in kind, wood for wood; fiber-cement and PVC are not recommended. Staff can usually approve front porch repairs as minor work within 3 to 4 days, and we keep the porch shored meanwhile.
What moves the price of wood rot repair
Our sources carry no Greensboro rot figure, so these are Angi's national numbers. How far the rot runs sets the real cost.
- How far the rot goes A sill corner is a patch; rot into rafters or a post base is structural.
- Height and access Second-story fascia needs staging, and porch roofs need shoring.
- Trim profile An old profile that must be milled adds shop time.
- The water source Drip edge, flashing or a rehung gutter make the repair last.
