We repaired the basement slab that was sagging at this house in Pierrefonds. Symptoms can be clearly seen in the cracks separating between the top of the interior walls of the basement and floor upstairs. By installing our slab piers, we did not just stabilize the slab, but also we were able to close the existing cracks as you see in these 2 pictures.

Uneven floor Insulation Finishing

We had an inspection done in our house and the inspector found possible traces of mold in the main attic and the attic over the garage. We are selling our house and would like to have the mold cleaned if it exists and what is the root cause.
Vicinity of Narcisse in Pierrefonds
There is humidity in the wall that surounds the basement it seems like it was way worst before becasue the wall is full of boubles due to water damage, but we open the wall to see and it does not look as bad. 3 contractors told me that maybe there is a crack in the fundation that let the water in during Spring when the snow melts. I would like to know if there is something in the external wall so that I can fixed it and close the internal wall. The same issue can be seen in my Chimeney, water gets in from the outside but this time we can actually see it because it is happening in an open area

My neighbour and I have both been flooded in our basement levels this winter. For myself, I'm not sure if I have a crack in my foundation, or if it is only that the ground slopes down. In any case, we are both looking for a company who deals with this and we both need to get it done as soon as possible come Spring, because there will be more water and flooding then. So, to re-cap, we both need an estimate, then the job to be done as soon as possible. Looking forward to receiving your answer! February 10. 2019.

Hi, We have a problem due to big temperature swings, we had the basement flooded. Never happened in the previous years (3rd year since we bought the house), and we don't think it's the foundation. there' might be a problem with the caulking and the fact that the french drain is too close to the windows and the house is inclined in a way that the water can come in if there's a lot. We cleaned the water within an hour and the carpet was relatively dry, but we don't know what to do next. I wish I could send you a picture of how it looks like from outside, but it cannot be attached here. Thank you!

Hello, The cold room in our house basement smells mouldy and seems to have moisture on the walls. The cold room is located under the front porch and I wanted to have it inspected to see if there is any mold buildup and to see the root problem of the smell and moisture. Thank you, Jessica

I want to install a sump-pump in my basement which is roughly 33' X 14' and has a floating floor. Probably a pedestal pump will be better but I would appreciate to have the cost estimates for both the options. Thank you.
