Est. time: 20 minutes Skill: 

Whether you’re installing an entirely new exterior door system or replacing your threshold – don’t overlook the benefits of installing a sill pan. Installing a sloped sill pan will add vital protection against damaging leaks for your entryway while protecting your wallet from extensive, costly repairs down the line. Our guide below will take you step-by-step through the process of installing the VersaPan Universal Sloped Sill Pan. The universal option can be custom formed to fit just about any opening size and is a great option for most projects. Before installing, make sure that the previous threshold or door system has been removed, as the sill pan must be installed beneath the door sill.

WHY INSTALL A SILL PAN?

Once installed, the sill pan creates a barrier against any water leaks that make their way underneath the threshold/door sill. This protection can guard you against costly damage down the line, such as footing the bill to repair a rotted out subfloor or rotted door jamb.
