Air Tightness Test Certificate Pending Before Final Payment Email Template

Use this page when final payment is delayed because the buyer says the air tightness test certificate, blower-door test report, or air leakage acceptance record is still pending. This is different from facade water-ingress or acoustic testing because it focuses on envelope airtightness and the formal certificate tied to it. The commercial problem is that the building shell may already be complete, but the payer is still holding payment until the airtightness results are issued or approved. Your email should ask whether the air-tightness certificate is the only remaining blocker, whether testing has already taken place, which result or approval is still outstanding, and whether payment will be released once that certificate is accepted. The outcome you want is to convert vague building-envelope concerns into one named test certificate with a clear release condition. It is commercially strong because energy-performance and leakage certifications can become late-stage payment blockers even when the contractor believes practical completion has already been achieved.
