Project Location: Dorchester, ON
Have had a leaky basement for the past year. we did a big reno on our house where we moved the septic to the front yard and they also put in new water mains & sidewalks in our subdivision. Not sure if all the movement has caused it because we never had problems for 8 years before this. We can't find where the water is completely coming in but we think the retaining wall on the front side of house. Not sure what we even need done, but would love for someone to have a look and give us their opinions on solution. We've already ripped up all the flooring and parts of the drywall to try and find where it is coming from

We have a 'cold' room that we use as storage, but some items develop mould and we would like to convert the room to just a regular room to use as safe storage.

Leaking basement
Project Location: Dorchester, ON
The basement in our 1953 built home is prone to high humidity conditions. I know from some digging near the house, that the water table is fairly close to the basement level. I believe that a sump pump would help this situation.

I just moved into this house in Sept 2020, I have water coming into my basement, it's coming in around the sewer hole-its make its way down to the sump pump thankfully.It appears this has happened before from the look of the water lines in the basement. I believe it's because the water is not being drained away from the house and it's finding a way in due to the spring thaw. is someone able to come look and let me know any possible solutions?
Project Location: Dorchester, ON
We have a cold storage unit in our basement that also houses a sump pump. We have issues with wet walls and would like a quote on how to solve the issue, please. Thank you.
