I'm in KW Region and wondering how much it would cost to enlarge a basement window from 46 x 14 (actual opening height is 12 in) to 46 in x 24 in?

Concrete needs to be cut downwards to increase the height. There is a window well with weeping pipe (I can see) going downward, also have some gravel on top in the well. This is a 5yrs old house taken from a builder.

To increase the height downward, does it need a new weeping pipe installed? I would appreciate if someone can provide a cost (approx) idea to increase my existing window with installation.

Hello MK,

You will have to extend the window well further down and add more gravel. The weeping tile would need to be cut down to the bottom of the window. As far as a cost is concerned, product and labour rates change from province to province. A lot could be taken into account as far as prep time for saw cutting the concrete. In Saskatchewan which is where I am located a project like this would run you in the area of $1600.00.

Hope this was helpful!
