Semi-detached. Unfinished basement. Blanket insultation. There is a leak in the basement under the insulation that is dripping on the side of the house that is facing the side-yard. The insulation material is wet for about a length of 1.5 meters and goes up to a crack that is going up to the ceiling of the basement. I am available anytime someone can come and give us an estimate to fix the problem.

My basement is leaking in various places (windows, wall cracks) particularly on the wall that is in the back yard and the one along my front driveway.

Wet basement due to groundwater
Project Location: Markham, ON
There is a water leak that occurs from behind one of the drywalls of my basement every time is rains too much. The amount of water is not a lot, but it goes into the laundry room and also goes under some laminate flooring (they have risen up because of the water). There is a window that was blocked off by the previous owner which is behind this drywall - I suspect the leak is from there, but it could also be from a crack, since I've had a crack before in another spot in this same basement (fixed by Clarke a few years ago).
