No mystery to it. Here is exactly what happens from the moment you call to the moment we hand the job back.
Walls probed for soft wood, moisture read, and problem elevations identified. The survey should produce a written list of repairs before a price is fixed.
Ground, windows and planting protected, then media blasting to remove failed finish back to sound wood, working systematically across elevations.
Rot cut out and treated, patches and half-logs fitted, and any full log replacements carried out. This is where discovered work turns up and where change orders originate.
Old chinking removed, backer rod sized correctly, new chinking applied so it can flex with seasonal log movement instead of tearing away from the wood.
Stain applied in specified coats with correct drying between, then a clear topcoat where the system calls for it. Weather windows govern this step more than anything else.
None of this is required — it just makes the visit quicker.
