Leaks around windows can be the result of issues in several locations:
- Window Seals . . . often need to be replaced to stop water inflitration.
- Main Door Rubber Seal . . . this seal or gasket often needs to be replaced to stop the infiltration of moisture that causes soft spots in the floor either in front of or to the sides of the door.
- Access Compartment Door Seal . . . another wear location that can be the source of water infiltration.
- Caulking around exterior window frame where it meets skin. It may be necessary to remove remnants of old caulk and thoroughly clean surfaces before applying fresh caulk.
- Other potential sources of water infiltration:
- Awning Rail. The rivets used to attach the awning rail may have loosened up creating leak opportunities, the caulk bead may also need to be renewed.
- Radio Antenna (if so equipped). The base gasket my be decomposing allowing moisture infiltration.
- Rock Guard. The rivets that attach the rock guard hinge may have becom loose over time permitteing water infiltration. The caulk bead may also need to be renewed.
- TV Antenna. Even though it is on the roof, its base seal can be the source of water infiltration that can find its way to a window frame where it appears as a leak.
- Roof Vents. Again, even though they are on the roof, a leak in their gaskets can be a source of moisture infiltration that can make its way via a rib to appear as a leak at a window.
- Air Conditioner. Another of the pesky roof penetrations where a gastket/seal can fail permitting wate infiltration that can appear as a leak elsewhere like a window frame.
- Plumbing Vents found on roof are another source of water infiltration that can find its way via ribs to become a leak at a window.
- Panel Seams. Exterior panel seams can also be a source of moisture infiltration. After cleaning any decayed existing sealant from seam (a sharpened popsicle stick or sometimes a tooth pick can be used to persuade the old sealant out of the seam).
- Clearance and Running Lights. The bases on these lights can become loose allowing water infiltration . . . removing them, cleaning the ground and sealing with fresh caulk can cure a pesky leak that may show up at a window below or near light.
As with most leaks on an Airstream, one culprit cannot be condemned as moisture will follow ribs, wiring, etc. and may form a leak many feet from the actual source.
Good luck with your investigation!
