How to Use This Calculator
- Count Window Count and Door Count to estimate exterior and interior perimeter caulk requirements.
- Measure Bath Linear Feet and Kitchen Linear Feet of joints needing caulk around tubs, sinks, and counters.
- Set Gap Width to the average joint width in inches — wider gaps consume more caulk per linear foot.
- Review Linear Feet Total to see the full scope of caulking work across all areas of the home.
- Check Tubes Needed and Total Cost to purchase enough caulk with a small buffer for waste.
- Use Application Time to schedule the project over one or two weekends based on your available hours.
