Window seam gap - can it cause rainwater leak?
In the fall I had a rainwater leak in the streetside bedroom floor. Trip to JC, Sealtech showed leaking areas – seams on rear endcap, middle rail at rear, rear storage trunk, and awning arms on the streetside. All fixed at JC, and for a price I thought was very reasonable. Airstream has been in inside storage since then. During the Spring I decided I needed to get serious about exterior maintenance, especially seam sealing. Using Acryl-R I sealed several areas, including around both windows closest to last fall’s water leak.
So last week I retrieved the AS from storage and parked it next to the house. It rained quite a bit overnight, and the next morning I relished the opportunity to check the Airstream and see how dry it was inside. Well you know where this story is going. Inside there was a drip along the interior bedroom wall, from the window to the floor, in exactly the same spot as last fall.
I tried to put my best face on for this development – no problems, just solutions – but my patience was wearing thin. After all of the fixes, both by JC and me, what could be left allowing the rainwater leak???
Well, I went outside to carefully inspect the window that I had applied the Acryl-R to. In a corner, there was a slight gap – maybe 3 or 4 mm. Actually there were 2 sections that had slight gaps, but the one on the right was exactly where the drip was on the inside of the AS. I don’t know if the gap shows up in the photos attached.
So what do you think – could such a small gap be the cause of my leak? Or should I keep looking?
I would really like to avoid putting the AS into a really big Ziplock bag! I am desperate to solve my leak problem! Any suggestions will help me, especially with all of the rain we’ve had this Spring.
