1. Record and contain
Log what's visible at the Columbus property, stop any damage that's easy to stop, and note relevant history.
2. Read the house and the lot
Columbus grew up where the Chattahoochee drops over the Fall Line, and that same geologic seam runs under half the city's neighborhoods -- Piedmont clay on one side, river-deposited sand on the other. Sorting out which side a house sits on comes before any repair method gets chosen.
3. Get it in writing
A Columbus scope should nail down materials, access, permits, testing, and what's excluded before anyone signs.
4. Weigh the bids
Compare reasoning and boundaries across Columbus proposals, not just totals, and verify credentials independently.
5. Confirm the finish
Testing, cleanup, paperwork, and ongoing maintenance should all be confirmed before a Columbus job is called done.
