Our house was built in 1885...we have a window well...I beleive it is a concrete type of substance...it used to be a coal shaft...the previous owners installed glass block in this window well about 8 glass blocks high and 5across..it has a dryer vented out of one of the glass blocks at the top....the only problem we have is the window well fills with water when it rains heavy..it doesn't leak into the basement (yet!) can we build up the wall higher in the basement and can we fill in the well with anything like concrete? we have tried the well covers like bubbles and stuff...doesn't work very well...we want a more permanent solution...
