OTEC can provide applicable after-sales assistance, maintenance guidance and warranty support according to the product, installation scope and written project terms. The support available for a new installation may differ from a product-only supply, replacement request or issue caused by unrelated building work. The most useful first step is to identify the installed system, project date, location, symptom, affected opening and any recent maintenance or renovation.
Keep the quotation, contract, drawings, product schedule, care instructions and handover records. Routine cleaning and timely reporting can help separate an adjustment or maintenance matter from a larger building-interface issue. Do not alter seals, hardware or drainage paths before the cause is understood.
Decision points
- Owner: Record the concern with photos, dates and operating details, and follow the agreed reporting and maintenance process.
- Architect/designer: Check whether the issue relates to the specified system, glass, hardware, exposure, interfaces or later design changes.
- Contractor/builder: Provide safe access, preserve evidence, coordinate other trades and document adjustments or remedial work.
Use the OTEC FAQ hub for related guidance, then contact OTEC with the project records and clear photos of the issue.
