What does flashing repair cost in Exeter?

Chimney flashing in Exeter is $480 to $1,200. Valley and wall flashing runs $620 to $1,900 depending on length.

Can't you just caulk it?

Caulk is a short-term patch. We replace the metal so the detail sheds water the way it was designed to.

Is flashing the usual leak source?

Yes — most roof leaks we trace in the GTA start at a flashing detail, not at the shingle field.

Documentation on everything
Photos, readings, and a written summary after every visit. Makes it easy to keep records for the house file.

Doug T. · 2026-01-11

Bundled two services, saved the trip fee
Had the chimney and the dryer vent done on the same visit. Cheaper and half the disruption.

A real person answers the phone
No call centre, no chasing. Booked in two minutes and got a text when the truck was on the way.

Ryan K. · 2026-02-28

Reliable across three jobs
Used them for a sweep, a dryer vent, and a fireplace service. Same standard every time and the same technician twice, which I appreciated.
