Looking to get an egress window done in my basement
Project Location: Ottawa, ON
Hi, I am looking to replace my existing sump pump with a submersible sump pump. My current sump pump is fairly old and our radon specialist wanted us to have a sealable/submersible sump pump. I don't think we would need anything fancy, I'm looking for quotes for the system, labour (and maybe add-on options, such as battery backup).

Basement leak.
Project Location: Ottawa, ON
Hello, The West and North foundation walls of the townhouse are wet (at bottom). There is also bad/musty smell coming from the underneath of the basement floor/concrete slab and from under the sump pit. There is also a vertical crack on the foundation wall that goes all the way down to the cove joint and then the crack expends to the basement floor slab. In addition, apparently there was a flood in the basement (from the washer). The water stayed for some time , probably water went bad and sipped down to the concrete of the basement slab (perhaps why such a bad smell). Could you please come and give me an estimate for the repairs. Regards, Val

I'm looking to convert 2 basement windows to egress windows. Possibly a third and maybe even a fourth.
Project Location: Ottawa, ON
I need to repair foundation cracks that have formed around my 2 basement windows. The cracks have formed due to old, poorly constructed window wells and old windows. Ideally, I would like to repair the foundation issues while installing new windows and window wells. Preferably egress windows.

I need to cut out the basement and to put up a larger size window. Existing window would not be enough to call it as a legal unit in the basement

I would like to get rid of the musty smell in the crawl space. I was thinking of installing a dehumidifer or anything else that may be required. Thanks.

I have a very slow leak coming into my basement, likely through the side of the house. It doesn't always happen when it rains, but does from time to time and I want to get it fixed. Thanks

More frequent intense rainfall has caused water to seep through foundation cement cinder blocks. With more intense rainfall, this is happening more frequently.

Hairline crack in foundation of a townhouse. The neighbours tell me you have fixed similar cracks in the other homes of the row.

Hello! We are looking to add a room to our 90+ year old home, either by finishing part of the basement or converting the garage. Both spaces have water issues and we're looking for a quote to have them fixed before we move forward with a renovation. While there has always been some effervescence and occasional dampness, recently there is some new water in the finished portion of the basement laundry room - wet and discolored drywall. This needs to be addressed first.
