1. Choosing the Right Size

  • Q: How do I know which size Sloped Sill Pan™ I need?

  • A: The Sill Pan size should match or be slightly larger (1/8” -1/4”) than the door/window frame size, measured from the interior side back to the nailing flange or brick mold.

2. Replacement Installations

  • Q: Can I use the SureSill™ system if I am replacing an existing door or window?

  • A: Yes.

3. Installation Without Removal

  • Q: Can I install the SureSill™ system without removing my existing door/window?

  • A: No.

4. Recommended Sealant

  • Q: What sealant do you recommend for sealing the pan in the rough opening?

  • A: Refer to the Recommended Products in the SureSill™ Water Management Guide for Windows and Doors.

5. Alternative Sealants

  • Q: Can other sealants work?

  • A: Other sealants may work, but we lack test reports on their performance with SureSill systems and cannot endorse them.

6. Flashing Tape

  • Q: Do I need to use any special flashing tape— butyl or asphalt-based?

  • A: Consult the Recommended Products in the SureSill™ Water Management Guide for Windows and Doors.

7. Alternative Self-Adhering Flashing (SAF)

  • Q: Can other SAF work?

  • A: While other SAF may work, we cannot recommend them without test reports on their performance with SureSill systems. A butyl SAF meeting AAMA standards should suffice.

8. Rough Opening Adjustments

  • Q: How much room should I add to my rough opening?

  • A: Add 1/4” – 3/8” in height, depending on the Sloped Sill Pan used. Check SureSill Specifications for details. [Link to SureSill Specs]

9. Installation with Screws

  • Q: Can I use screws through the SureSill?

  • A: Yes, but ensure all penetrations are sealed. Drill a pilot hole filled with sealant, use stainless steel screws, and cover the fastener head with additional sealant.

10. Choosing Fixed Depth or Adjustable Pans

  • Q: Should I buy 11X or fixed depth pan?

  • A: Fixed depth pans are easier and more cost-effective, but if a special size is required that isn't available, 11X pans may be necessary.

11. Painting SureSill

  • Q: Can SureSill be painted?

  • A: Yes, after cleaning, SureSill™ products can be painted with paint designed for vinyl/plastics.

12. Level Doors with Outdoor Surfaces
