What drives the decision
Condition, adhesive, pane size and access determine how much work removal creates.
What changes the budget
Removal should appear as a separate line item in quotes instead of being assumed free.
Operations and lifecycle
Replacement is a good time to reconsider whether the old tint level and performance still fit the building.
Planning boundary
Use trained contractors and manufacturer methods; this site gives no scraping or chemical-removal procedure.
Educational planning only. Actual construction, code compliance, regulated systems, hazardous materials and safety-critical work require qualified professionals and current local requirements.
