Question DetailsAsked on 7/27/2015

My basement window leaks when it rains, it has a gutter around it but water still leaks in, who can i call

Every time it rains, the water pours in the basement through 1 window. It has a gutter around it, I even brought a cover for it to keep the rain from getting down inside. is there something I can do or do I need to call a professional to come and take a look at it. And if I do how much would something like that cost??? I don't think calking the window would do it. I think that it is going down into the rocks that are inside the gutter that is supposedly stop the rain from coming in. So it is a bigger problem.

Came across this question looking for reference questions to answer someone else's similar question. Just in case you have not solved this issue yet:

Assuming the rainwater coming in is flowing into the window, not just leaking in because of poor perimeter caulking around the frame, couople of solutions:

1) the "gutter" you are talking about, I presume is a "window well" - a metal or plastic half-round "pit" surrounding the window and holding the dirt back from it. That obviously needs to be watertight - so any holes in it need to be caulked or plugged, and if the water leaks in around the connection to the wall that needs to be dug out and sealed - normally with asphaltic roof sealant, available in quart and larger cans and also caulk tubes. Best to looses up the connection and put the sealant in the contact zone and then tighten down, but just caulking around the interface on the "outside" or the well will commonly work OK.

2) obviously, the well has to be above water level when it rains - it surfacea water is overtopping it then it either has to be raised, or a berm of compacted low permeabilityi (clayey) soil or concrete has to be put around it to dam off the water coming into it.

3) your cover might be taking care of this, but obviously if roof runoff is going inot the well that is a problem that needs to be taken care of with gutters or with a deflector over the well

4) if water is rising in the well from underneath, then you need to seal the bottom too.Normally, in relatively free-draining soil, some rock or gravel is put into the bottom to act as a drain for the little rainwater which will get in there. But is the groundwater is rising enough, or leakage around the well down and under the bottom edge of it, is enough that it fills from below, then you need to clean it out to well below window frame level, dry it, put a layer of fibrous (has fiberglass fibers in it) asphaltic roof sealant on the inside of the well and the outside of the foundation around the bottom where the concrete will go, then mix up and put ready-mixed sack type concrete in there to seal it - about 3 inches would be preferable, which may be about 1-4 bags worth depending on well size. Concrete should be well below the window frame level (but obviously inside, not below the bottom of the well itself) to leave some room for minor leakage to accumulate in the well.

If not able to DIY this, an Handyman can pretty readily handle it for a hudnred $ or two depending on the fix needed - your primary role would be to observe at the next sugnificant rain to see where the water is coming from - from above, over the rim of the well, at the well/foundation interface, or in from the bottom - or a combination of these maybe.
