Question by Mapon61: Water leaks from windows in strong wind and rain, comes out bottom of window. What professional do I need?
The water seems to run over the bottom of window when there is straight line wind and rain. The company that installed the windows made the weeps wider to carry off more water, but that didn't do it. Can only determine if leak is fixed when there is a sever storm. So the warranty is out and it is still leaking during these heavy storms. We have to use towels to caught water during these storms.
Answered by LCD: Here is a link to a similar previous question FYI -
You might be able to tie it down by carefully running a hose around the window, starting at bottom and moving up, and seeing if the leak is from a gap AROUND the window frame, coming through the weatherseals on the moving window components themselves, or just leaking in because the ewater in the tracks is overflowing the tracks. First requires flashing/caulking repair, second replacement of weatherseal, third cleaning of the drain passages from the track (may be blocked at the weep slots in the outer track, or if the water passes through the interior of the extruded aluminum sill the inlet and/or outlet in or under the face lip of the window may be plugged with debris or caulked - try cleaning out with flexible automotive oil passage brush or long pipecleaner if there is an interior passageway in the sill. (If you have make/model, check manufacturer website for diagrams of how the water is supposed to get out). Could also be that the watershield used in the rough opening is blocking or catching the water and bringing it back indoors, if the water is coming out UNDER the inner sill.
IF overflowing the inner track lip (the inner guide edge for the inner window) check the window installation is not tilted towards the inside, and of course that the track is not damaged, forming a low spot. Some designs have very little freeboard - I have seen fixes for that done with stickyback plastic door weatherstrip stuck to the outer face of the inside track edge (after it is cleaned well to provide adhesion), using a strip like this (if your window has clearance for it) - comes in white and brown at least -
You would have to caulk the ends to seal that entry point, and would visually leave a plastic strip sticking up in the air a bit (probably not real noticeable except when window is open), but if it works ...
Other alternative is putting a shed roof or awning over the window if that would block much of the blowing rain - might not if your rain is near horizontal.
One other thing - since you filed a claim under warranty and the contractor came out to fix it, but that fix did not work, techincally your warranty claim is in the system and they are liable to repair the problem (or replace the windows if they can't) even if it is now past warranty time, because you did file the claim in a timely manner. This assumes it has not been long or more than one major windy rain storm since he "fixed" it, so you are reporting the failure of his fix in a timely manner. However, the FILING of a claim under a warranty is what is under the time limit, not the actual fix, unless specifically stated otherwise in the warranty.
If he flat out refuses, then about all you can do is drop a hint that his refusal to back up his warranty will be noted to the manufacturer and on an Angies List review - that might get his attention and get it done. That assumes of course he can actually "fix" it - that the window is not installed wrong or backwards (amazing how many times you see that, especially on sliders and sliding glass doors and french doors), and also that when he widened the drain slots that (if a hollow aluminum extrusion) that he did not create an opening into the hollow extrusion that is then draining into the house (though would almost certainly appear UNDER the window frame in that case).
