Your Home faces Water Damage

1. Ontario receives a good amount of rain and when you add on melting snow flash floods are a serious concern.

2. When flooding hits your area, your basement is most likely to be the prime target for water damage.

3. If you allow it to be wet, moldy, humid, smelly, and unhealthy, you're abandoning an entire floor of space in your home. Additionally, the basement air - filled with odors, dust mite feces, humidity, and mold spores - will rise into the rest of the house, ruining the healthy environment of the home.

Project Location: Hartley Blvd, Milton, ON L9T 6K9

Comment: Hello, We moved into a new house last month and are planning a basement renovation in the next 1-2 months. Before doing so, I want some confidence in our flood prevention systems. I don't know the repair history of the existing sump pump, but I know that it runs much more regularly than our last house, and when it discharges, it seems to discharge a lot of water. I'm contacting you because I'm interested in: a) Getting professional advice on if we should consider improving/upgrading what we have b) Getting a battery backup and a flood sensor c) Getting advice on external drainage to redirect the sump pump discharge further away from the foundation Thanks, John
