THE SHORT ANSWER

How to Estimate Dry Rot Repair

20 sq ft of local siding rot with replacement and 8 labor hours at $60 totals about $1,390.

01

Measure the affected area

Dry rot prices by the area of affected wood. Measure the rotted boards or framing you will cut out and replace.

  • Affected area
  • Siding / fascia / frame
  • Local vs extensive
  • Repair vs replace
02

Location changes the rate

Siding rot is straightforward; fascia and soffit need ladder work; window and door frames need careful removal.

03

Local vs extensive

A local patch repairs fast. Extensive rot spread across a wall or frame multiplies the area and hours.

04

Replacement is usually required

Dry rot rarely repairs cleanly; cutting out and replacing the member is the durable fix. Quote replacement to be safe.
