1. Observe and protect
Document what's happening at the Columbia property, limit further damage where it's safe to do so, and collect whatever history the home has.
2. Evaluate the house and site
Because Columbia's clay and sandy transition soils shift with the seasons, this step checks moisture, contamination, cracks, joints, surface profile, cure temperature, UV exposure, and traffic before any coating gets proposed.
3. Define a written scope
Get preparation, protection, materials, access, permits, testing, cleanup, finish restoration, exclusions, and change-order terms written down for the Columbia project.
4. Compare providers
Weigh the reasoning and boundaries behind each Columbia-area proposal, not just the total cost, and verify credentials along the way.
5. Inspect closeout
Before calling a Columbia project finished, confirm test results, cleanup, paperwork, warranty terms, and whatever maintenance responsibility remains.
