What do I do when sealing after insulation makes leak repair hard?

Sealing, Leakage, Mastic & Pressure Testing.1 field-polished — seal/test detail check

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

Field checklist

Ask foreman

Do you want sealing verified before insulation covers these joints?

Do not

Do not let insulation hide known unsealed work.

Why it matters

Hidden leaks can mean cutting insulation open later and reworking finished areas.
