Sealing after insulation makes leak repair hard

Seal before insulation blocks access whenever the project sequence allows it. Once wrapped, leaks are harder to find and repair cleanly.

Stop if

• Do you want sealing verified before insulation covers these joints?

Watch out

• Do not let insulation hide known unsealed work.

Check

• Look ahead before insulation starts.
• Check joints, collars, access doors, and flange corners.
• Mark anything that still needs seal.
• Ask whether insulation should hold until sealing is verified.
• Photo completed hidden joints if required.
