Replacement vinyl window glazing bead

A home owner from Hurst, TX says:
The beads on our sunroom's exterior are getting brittle/broken and starting to curl up. Of the 18 windows, only two leak water, but from the look of the blinds they all seem to be letting in dirt. Caulk doesn't stick; is there another way to seal the undamaged ones?

Hello! Let's start with the replacement glazing first. Your pictures look like our 55-033. Please compare our measurements to yours to confirm.

Regarding the leaking and dirt, vinyl glazing isn't usually the primary means of preventing leaking. Rather, it is the caulk. Many service people used Phenoseal caulk, which is a vinyl adhesive caulk.

Before you apply your caulk, wipe down the section you are caulking with alcohol to remove the dirt and oils that are preventing it from sticking.
