Questions
About the liner and materials calculator
How accurate is this?
It uses overlap and waste allowances and standard roll sizes. Odd shapes and many obstacles change the real numbers, so we measure on site.
Why does the liner area exceed the floor area?
The liner runs up the walls, wraps the piers, overlaps at seams and includes some waste.
Can I install it myself?
Some owners do. Our service pages explain what a proper job includes, and we are happy to help with any part of it.
