If the issue is with the manufactured window or component: the manufacturer warranty applies. That can include items such as insulated glass, balances, locks, frames, screens, hardware, or finishes, depending on the specific warranty.
If the issue was caused solely and directly by Blue Haven's covered installation work: Blue Haven Windows evaluates the workmanship claim under its Limited Lifetime Installation Workmanship Warranty.
If both may be involved: Blue Haven can help identify the likely path, but Blue Haven does not independently guarantee manufacturer approvals, part availability, shipping, or product-defect outcomes.
