How the visit works

1. 1

   Find the real leak source

   We water-test the chimney to confirm flashing, not the crown or brick, is the entry point.

2. 2

   Strip the failed metal

   Old tar patches and surface-mounted flashing come off completely — we never layer over them.

3. 3

   Install and lock in

   Step flashing woven shingle by shingle, counter flashing cut into the mortar and mechanically fastened.

4. 4

   Seal, test and warranty

   Terminations sealed, a second water test run, and a written workmanship warranty issued.
