Document the condition
Note where the issue shows up, when it started, whether storms or heat seem to trigger it, and what's already been tried—a couple of photos help the first call.
Read the local context
Johns Creek is dominated by planned neighborhoods, larger late-20th-century homes, and premium newer construction. Rolling wooded lots, red-clay soils, humid summers, intense storms, and high household demand shape mechanical and remodeling plans.
Ask what will be hidden
A scope focused only on equipment misses the point—duct leakage, insulation, and electrical capacity matter just as much, and it should explain how that hidden work gets verified once it's closed up.
Compare complete scopes
Hold every quote to the same list: protection, access, materials, permits, testing, and what counts as a change order.
What official local sources add
Johns Creek provides a project-specific permit guide rather than treating every repair alike. Its examples show that water-heater replacement, grading, driveway changes, fences in sensitive locations, and other work can trigger separate building, trade, or land-disturbance review.
