THE LIMIT

One answer cannot certify a hidden condition.

Avoid ladders, roofs, flooded electrical areas, unstable excavations and changes that direct water onto neighboring property. Significant foundation movement needs qualified review.

THE HANDOFF

Evidence makes the next step faster.

Provide rainfall timing, photos during flow, downspout routes, grade direction, ponding duration and the interior area affected.
