Questions
- How long do vinyl windows last?
- Typically 20 to 30 years. CapexClock uses 25 years as its default, and you can change it for your building.
- When should I start saving to replace vinyl windows?
- As soon as they're installed. Spreading the cost over their 20–30 year life keeps the replacement from landing as a surprise. The mini calculator on this page shows a monthly amount for yours.
- How are vinyl windows priced in the calculator?
- By default they're priced per unit. Enter your own quote or recent invoice; CapexClock never fills in costs for you.
