I require my crawl space to be encapsulated. It is approx. 20 X 25 feet and less then 3 ft high.
Project Location: Thorndale, ON
Crawl space is poorly sealed not well insulated. We'd like to have warm floors and no place for animals to enter.

I recently purchased this home & there was an issue on closing due to water being in the basement. The sump pump has been going off every 3 -4 minutes. This property is a 2020 build and the builder/owner didnt grade the property & there was no gutters. I am installing gutters this Thursday & need to figure something out to protect my home.

After the last heavy rain we had a week or so ago, i found water in my basement in one room and i am not 100% sure on where it came in as the basement is finished. I would like to have an expert look at it and give me a price on fixing. Thank you.

Leak in basement
Project Location: Thorndale, ON
Not sure if you guys offer a solution to my problem, but I am seeking ideas and quotes to repair what appears to be a sunken exterior wall. I have not finished gutting the room so details are scarce, but we are hoping to repair the structure of the room and turn it into usable living space. I would appreciate having someone come out and take a look and see if you offer a solution. Thank you.

We have a crack and leak in the basement and wanted to get an estimate to repair it. Thanks.

Winmar is currently cleaning and repair water seepage damage to my basement. There has been a small amount of seepage for a long time, but this time, the entire basement got soaked. When the repairs are completed (or even before), I would like to get proper drainage installed for the house, as well as possibly concrete re-levelling in my garage with better drainage there too. Thank you!

The house is old and has a poured basement there has been water damage and the walls have some mold. If I keep the rain water away from foundation I get no leaks coming in but found this out after a few bad storms aqnd water came through walls. The walls have been painted but there are spots were the concreate is falling out. Im not a expert so thats why I would like someone to come and take a look and give me an honest opinion on what I can do. Like I said if I keep rain water from the walls its fine but the damage is already done and the wall look terrible. Its not a finished basement just laundry and storage.

We have a strange smell in our basement, and our house is relatively new. We are hoping to finish our basement, but not before we take care of the smell. It doesn't smell everyday, but recently more than normal and because it's open to the main level, it comes upstairs as well. We don't think it's sewer or gas, and it doesn't smell like musty basement either. We are located less than 5 minutes from the London airport.

Am interested in pricing for someone to check sump pump. House is 2 years old and the pump has not yet been checked for service needs
