1. Observe and protect
Note the symptoms, limit further damage if it's safe, and pull together any history on the area.
2. Evaluate the house and site
Excavation, compacted base, soil condition, thickness, reinforcement, slope, joints, curing, access, and runoff determine performance long after the surface is finished.
3. Define a written scope
Get preparation, protection, materials, access, permits, testing, cleanup, and change-order terms in writing.
4. Compare providers
Weigh the reasoning behind each Durham proposal — not just its bottom line.
5. Inspect closeout
Confirm testing, cleanup, paperwork, warranty terms, and any maintenance left to you.
