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.

Testimonials
  • "You should be really proud of how well every member of the team does their job." Read Full Testimonial

    Tracey H. of Fort Erie, ON

    Customer Testimonial

              Your entire organization deserves to be commended for the professionalism displayed throughout the process. Every person that I interacted from Omni was impressively thorough, helpful and professional – from Mark who did the assessment to Pete who followed up, to Ryan and Shea who conducted the work. I have already referred Omni to two of my neighbors who require new sump pumps and I hope that they decide to call. They won’t be disappointed. In this day and age where everyone claims to put the customer first, you actually delivered, and you should be really proud of how well every member of the team does their job. Excellent work!"

              Ryan and his crew were wonderful. They were so nice and police, explained everything and gave me advice. They were very clean and did an amazing job of keeping dust out of my home, beyond my expectations. If I had another basement and needed work done I would definitely call you. And I would ask for Ryan.

    Customer Testimonial

              David was kind, friendly and very thorough. Analyzed, measured and explained everything to me on what would be the best solution for my basement problem. :) Gord and his crew (Andrew and Baron) were polite, courteous and professional. Protected my floors and walls. His team was clean, efficient, knowledgeable; ensuring I knew the system and the backup battery system operation. Gord's crew works like a well oiled machine. So pleased with them. When jackhammering, the debris was removed as they worked making the littlest amount of dust. They cleaned up and you would never have known they were here. Friend of mine used Omni Basement Systems and gave the company a rave review.

  • "I cannot thank OMNI basements for doing such a wonderful job" Read Full Testimonial

    Heidi and Sander V. of Niagara Falls, ON

    Customer Testimonial

              From the time I made my initial call to OMNI BASEBEMENTS to enquire about the leak I had in my basement. The secretary who returned my voice mail was very pleasant and returned my call promptly. An Appointment was set up for OMNI basements to come and inspect my basement. A package was sent to my home with all the information about this company and a detailed book of all their products. At first I thought this was over the top, such a nice booklet about all their products, but this did give an opportunity to read and be knowledgeable about their products. Lou then came to my home and inspected my basement. From there we sat and discussed my options. Lou was very informative and knew the products very well. I agreed to have the work done feeling very satisfied I was making the correct decisions. Lou did not try to sell me more than what was required. Truly professional. When the work crew came out to my home, I can’t tell you enough how impressed I was. From the moment the trucks arrived, I was greeted by the supervisor, who introduced himself and his work crew. Right from the get-go, great care was taken providing mats to cover my existing flooring. The crew started immediately and worked like a well-oiled machine. Each member of the team worked very hard, other than the jackhammer, the noise was to a minimum. They respected that this was my home and every measure they took was that of utmost care. The end result was perfection. Not one thing was done half-heartedly. Even the garden where the pipe was coming out of the house was done so with such care. The supervisor felt it best to bury the pipe keeping the garden undisturbed. He even went the extra mile to tuck in a bit of cement where one of the stones was taken away, so esthetically you would never know. I cannot thank OMNI basements for doing such a wonderful job. I wish I could express to others that if you are considering work to be done in your home, this company has good old fashioned values, they take pride in their workmanship, very polite, professional work crew from start to finish. Clean up was such a pleasant surprise. They even pulled up the truck on my driveway, came back out, swept a few remaining stones that fell on my driveway. Again, the work ethics of this company is top rate!
