Work requests in Dorchester, ON Project Location: Dorchester, ON

We have only been in our house for a year come January. We have a fairly dry unfinished basement most of the time. Even after it rains, the sump pump doesn't run. I believe the water around our house drains pretty well. Our issue is when we get an excessive amount of water for an extended period of time. What happens is that the water table raises and our basement is surrounded by a lake. Our sump pump will run for days or even weeks until the water table naturally lowers. This summer, we had so much rain that we had 1.5 feet of water in the basement. Our sump pump was running non-stop, but couldn't keep up. Water was coming in through the foundation. This was an unusual amount of rain. Our neighbours who have lived in their house for 40 years have never seen anything like it.

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.

I had a hard time finding wall finishes on your website. Jordan told me about Everlast wall finishing but I couldn't find it and it isn't the great book that James left us about Dry Basement Science. Woops just found it on page 51 but it isn't listed under chapter 6 index.I got the information from Jordan who gave me a price but it is too much at this time.I would like to have our two other walls waterproofed and WaterGuard installed. I also like the idea of the SaniDry system as well.

All in all it has been a unusually pleasant experience with little inconvenience. The worst part was getting a messy basement cleaned up but I can't blame you for that :)Let it rain, let it rain ,let it pour rain!

I am impressed with the warranty offered on the process. Once the water is flowing and I know for sure that the process works I will feel more confident in my choice to go this route. Thank-you.

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?
