Quick answers

Why does exterior trim rot?

Trim rots when it stays wet long enough for decay fungi to grow. The USDA Forest Products Laboratory says wood kept at 20% moisture content or less has a reasonable margin of safety against fungal damage, so leaks, failed caulk and bare paint are the usual causes.

Can rotted trim be patched instead of replaced?

Small, shallow soft spots can be dug out and filled with a two-part epoxy wood filler. Once rot runs deep or the board splits, replacing the section is the lasting fix, and the water source has to be stopped either way.

Will rot spread if the wood dries out?

No, not while it stays dry. The Forest Products Laboratory says wood kept air dry will not decay and rot already present will not progress. That is why fixing the leak or seal matters as much as replacing the wood.

What 24/7 Express Handyman Service does on site

How it works

  1. The damaged areas are probed and photographed, and the water source is identified.
  2. The repair is priced in writing, with notes on anything that points to a bigger problem.
  3. Rotted wood is removed, replaced or filled, then primed, sealed and painted.
  4. Referred out: rot that reaches framing, sheathing or roof decking, and roof or flashing repairs causing the leak.

When to stop and call

If a screwdriver sinks into wood at a window, door or roof edge, or rot is spreading, call. 24/7 Express Handyman Service can cut out and replace the bad trim and refer structural damage to a licensed contractor.

What happens next

Every job 24/7 Express Handyman Service takes on is under $3,000 including labor, materials and any change orders (Utah Code §58-55-305); a change that would push a job over that line is referred to a licensed contractor, not written up as a second job. plumbing, electrical, HVAC, gas appliance / combustion system work is referred to a licensed trade.
