I have a leak in a vinyl liner in a very difficult place. Under my stairs.. below the bottom flange, the liner has pulled or torn loose. It has exposed a patch of the underlying bottom stair wall about 1/2 in x 2 in. A couple of old screw holes are visible. It is leaking. Is there a way to fix? It is about 5 years old and in otherwise ok condition.
Thanks for any help/advice you can give.
