Describe the reported symptom
Rainwater near a chase is a different starting point from smoke, combustion or venting concerns. Make clear which issue you are reporting and whether another professional has reviewed it.
Keep exterior work defined
AWC’s focus here is the exterior enclosure, roof and wall interfaces and related construction restoration. This is not an offer to sweep, certify or service a fireplace or flue.
Use qualified system review
CPSC recommends professional inspection of fuel-burning systems, including chimneys, flues and vents. An exterior water repair is not a substitute for that review.
Coordinate the records
When more than one trade is involved, keep their reports and work scopes together. That helps avoid assuming one person’s work includes another system.
Photos help start the review. Access, concealed conditions and required professional review can change the construction scope.
