The 5 Best Waterproofing Contractors in Winnipeg Who’ll Keep Your Home Dry Year-Round
When the pandemic hit, and I had to work from home, I ran into a serious problem: there wasn’t enough space to set up an office and work without distractions.
The only area with potential was our basement, but it was a mess, which is why I decided to look for a reliable basement renovation contractor.
However, another issue came up when it started raining, revealing several leaks we hadn’t noticed before. That kicked off our search for the best waterproofing contractors in Winnipeg.
How much does waterproofing cost in Winnipeg?
1. Proterra Concrete Solutions

Phone number: +1 431-996-5438
Business hours: Monday to Saturday: Available 24/7
Proterra Concrete Solutions takes pride in delivering superior results with minimal disruption by injecting fewer, smaller points compared to traditional methods.
They offer multiple waterproofing services, including basement waterproofing, joint sealing, crack injection, and foundation sealing—enough to cover all your home’s needs.
To ensure they’re the right fit for your property’s situation, they conduct an on-site assessment to identify the root cause of the issue. Clients we spoke to also appreciated the contractor’s five-year workmanship warranty that covers labour and application errors.
Their customer commitment extends beyond the warranty. Patrons also love that the company carries comprehensive general liability insurance, which protects them financially from injuries and property damage.
But for us, what distinguishes them is their around-the-clock availability from Monday to Saturday, allowing them to respond to emergencies. However, we’ve heard that booking an appointment can be challenging due to their popularity.

Clients commend the company for operating 24/7 and dispatching a team, regardless of the time of day. That said, some customers have reported that the crew failed to show up on the agreed-upon appointment date.

3. Blue Maxx Basement Systems

Address: 3300 McGillivray Blvd #3, Oak Bluff
Phone number: +1 204-864-2500
Business hours: Monday to Friday: 8:30 AM to 4 PM
Blue Maxx Basement Systems is one of Winnipeg’s top foundation repair companies that has been around for more than 20 years.
The entire team attributes their longevity to their collaborative approach. They work with clients to develop plans that address their home’s unique needs.
From engineering and permit applications to scheduling and executing repairs, they take full ownership of every aspect of a project.
Their core specialty is basement waterproofing, covering a range of services, including exterior and interior draining, encapsulation, and sump installation.
Clients we interviewed liked that the company provides manufacturer-supported warranties, because these guarantee the performance of the materials used.
The only drawback we noticed is that they don’t operate on weekends. This can be a hassle for those who are busy during the week.
They quickly came up with a game plan to fix our leaking basement
“Two years ago we noticed water leaking into our basement through a crack by a window. We called Blue Maxx to come take a look and quickly came up with a game plan to fix it. The crack was accessible from digging up a corner of the foundation and the repair took two days, including digging out the foundation and cleaning up afterwards. Blue Maxx put in new window wells and fixed the grading on top sealing the crack. We have seen no signs of water inside since. I highly recommend contacting them for what you need.”

The crew showed up on time every day, were super friendly, and kept everything clean before they left. The work they did was excellent, and we’re really happy with the results. Highly recommend them!”

Ground Down Foundation Repair has been delivering permanent structural solutions for Winnipeg’s unique clay soil for over 20 years. We were impressed by the over 600 projects they’ve completed since their founding.
They specialize in basement waterproofing, utilizing a combination of exterior membranes and interior drainage systems to create an impermeable barrier against groundwater.
For added protection, they also offer sump pit installation with backup power options to remove rising water mechanically.
To provide peace of mind for their clients, they back all projects with a lifetime transferable warranty. This means their repair services are guaranteed for as long as your house exists.
