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.

    Mel and Janet D. of Dunnville, ON

    Customer Testimonial

              This whole experience was positive. I dropped in at a neighbor's home and saw the work, spoke with Alfredo, telephoned for a salesman to come. Office staff always helpful and patient. If all crews and staff are as good as the ones we dealt with, you will soon be, if not already, number one in basement waterproofing. Today and last night we had 5 inches of rain and the basement and crawlspace remained dry! Wonderful! We should have done this sooner! We have and will continue to recommend this company to all our friends and neighbors.

    Shirley C. of Hamilton, ON

    Customer Testimonial

              After a recent heavy storm, Shirley C.'s basement was completely under water. "Water was coming in like Niagara Falls," she lamented. She couldn't handle another basement flood and she knew she had to do something right away.That is when she called Omni Basement Systems. Omni Basement Systems is Greater Hamilton's premier basement waterproofing company, offering over 28 exclusive, patented products to custom design a solution for every type of wet basement problem. The system design specialist came to Shirley's home, inspected the basement and explained to her what her options were to fix the problem. She opted for having a full WaterGuard, internal perimeter drainage system installed and a powerful sump pump system to pump and discharge the water as far away from the house as possible. Shirley was very impressed with the whole process. From inspection and sales, to completion, she was treated in an exceptionally courteous manner by the whole team. The job was performed with care, extreme attention to detail and excellent workmanship. "He treated me like royalty...that is what he did!" says Shirley of her design specialist. "And the crew worked just as hard as he did!". Shirley no longer worries about her basement flooding every time it rains. She knows her basement will be dry and healthy for as long as her house stands, thanks to the periodic maintenance service program and the Transferable Lifetime Warranty from Omni Basement Systems. If your basement is flooding, leaking or has mould or musty smells, Omni Basement Systems can help.

    I was waiting for a large rainfall to test out my new basement system, which finally we received on May 31st. I am happy to report the basement has remained dry. I was a bit nervous due to the fact in the past even a light rainfall would result in water in the basement area. Thank you for correcting this problem!!
