James AllenI used to be a miserable member of the Wet Basement Club and let me tell you, it was a soul-sucking nightmare. Every day, I had to deal with water nastily seeping out of cracks and mould stinking up the place.
Luckily, things didn’t go from annoying to disastrous, and I owe it to excellent waterproofing contractors. They patched up the mess, prevented future issues, and, in turn, fixed my sanity.
Fast-forward to now, and my basement is bone-dry and further renovations (Basement Renovation Toronto) are no longer needed. You’ll get the same luxury by hiring the best local waterproofing pros below, meticulously handpicked and checked by our team.

DryMax Waterproofing Shows Why Professional Help Matters — Especially When Black Mold Is a Risk
DryMax Waterproofing proved just how important it is to hire professionals—especially when it comes to waterproofing basement walls and preventing black mold.
What started as a simple issue turned into a big problem when I noticed water seeping through our basement wall. I initially thought it was something minor I could seal myself, but the damp spots grew quickly—and that’s when I started to worry about black mold forming behind the drywall.
Thankfully, I called DryMax early in the day, and they picked up right away. Their licensed and insured team arrived fast, identified the source of the moisture, and waterproofed the wall properly from the outside to stop future leaks.
They didn’t just fix the damage—they explained how untreated moisture can lead to hidden mold growth, affecting air quality and your family’s health. Their knowledge and professionalism gave me peace of mind.
Now I understand how serious basement water issues can be—and why you need a company like DryMax to handle it right the first time.
Why I Trust DryMax Waterproofing:
- 25-year warranty on waterproofing services
- Experts in interior and exterior wall waterproofing
- Helped prevent potential black mold
- Fast, clean, and professional work

Did an Exceptional Job
“Vasyl helped me out during the early stage of the pandemic. I had a leak in 2 areas of my basement. His team came in, dug a hole, sealed it and cleaned up within several hours. For the price, he did a fantastic job. Highly recommend!”
-Jason, DryMax Waterproofing Testimonial
Excellent Service!
“I hired Drymax Waterproofing to waterproof the sides of the house, install a sump pump and a backwater valve. The agreement contract was transparent, and the price was reasonable. Vasyl came on time, worked very hard for two days. They really knew what they were doing, and it showed: the entire job was a success. Many thanks for Drymax!”

Royal Work Basement Waterproofing Toronto
Address: 230 Queens Quay W
Contact Details: +1 416-837-1077
Operating Hours: Daily – 24 hours
Royal Work Basement Waterproofing Toronto has bagged numerous HomeStars awards. That’s no fluke, as evidenced by their 5-star ratings on Google Review.
What’s more, they’re backed by about 25+ years of experience.
Moreover, they usually finish in about 1–2 weeks, but simpler jobs can go faster.
The basement’s state or age won’t stop them. One interviewee even claimed Royak Work successfully waterproofed their 150-year-old townhouse.
Furthermore, their service list is extensive: exterior, interior, basement, and foundation waterproofing/underpinning are on the table.
As for the cost, we consider them competitive, especially with their $80 starting price for basement waterproofing.
A previous client we chatted with reported communication delays, though. Also, they’re in high demand. Securing a slot, especially in peak hours, can be tricky.
Beyond that, they’re a solid pick, particularly considering they come with a lifetime warranty!
We Will Definitely Recommend Royal Work
‘Thank you, Anatoliy and your term members, for your great job done. Your professionalism is appreciated! We will definitely recommend Royal Work to our friends when they need, just as how our neighbor recommended Royal work to us.’
-Julia Canada, Google Review
Fast and Extremely Tidy
‘After decades of water leaking into our 150 year townhouse’s unfinished basement, the recent heavy rain caused severe flooding that couldn’t be ignored. The remedy was to waterproof the exterior walls. Royal Work sent Jeremy and Vasyl, who worked tirelessly, in a very tight space, for three days, excavating, waterproofing and filling trenches for 8′ section on one side, and a 24′ wall on the other side. They were professional, fast and extremely tidy. We are thrilled with the results! I highly recommend this company and their team :)’

Basement Systems Toronto
Address: 1735 Bayly St, Pickering
Contact Details: +1 647-692-4333
Operating Hours: Mon to Fri – 8 am to 5 pm
Most of our teammates go with Basement Systems Toronto, and there are solid reasons why.
Experience plays a big factor. They’ve been in the business since 1987, and those 38+ years gave us confidence in their work.
So far, we’re right, as their inspections have helped us prevent potential issues like leakages and mould. Responsive specialists like Charlie are also well-versed in explaining the technicalities.
Service-wise, they offer plenty. The list includes waterproofing solutions (moisture and seepage mending), crack repairs, sump pump installation/maintenance, and foundational fixes.
The biggest draw is they’re efficient, finishing lighter tasks, like crack repairs, in a day. Meanwhile, heavier work, such as internal waterproofing, takes under a week.
Most importantly, they offer lifetime transferable warranties, ensuring their solutions last for generations.
That said, the weekend closure is a drag. They’re also 42 km away from downtown Toronto, so it’s usually a 30-minute wait for their specialists if you’re in the said area.
I Really Appreciate All Their Help
‘our basement looks much better now that they put the brace and put a new concrete. I really appreciate all their help most specially Haithem for explaining it properly to us and and his very nice team to fix it.
Job well done👍🏻’
-jo, Google Review
Very Happy with My Experience
‘Haithem came in to do a consult on my Basement and to assess if there was any foundation issue. He was thorough in his inspection and took his time to answer my questions patiently.
He assessed the crack in my basement wall and ran through the options available. Very happy with my experience with him and I am glad to have received his advice on my situation.’

Aquatech Basement Waterproofing Toronto
Address: 20 Hyde Ave
Contact Details: +1 416-300-2191
Operating Hours: Daily – 7 am to 12 am
If a highly professional and friendly team matters to you, picking Aquatech is a smart move. Clients we chatted with praised their crew—particularly Slava—saying they did the task timely, personably, and effectively.
They also arrive promptly. Those in Toronto’s CBD, for instance, normally just have to wait about 22 minutes.
Regarding services, Aquatech fulfils the ‘comprehensive’ requirement. Long-lasting basement waterproofing and repair are available, alongside other solutions like foundation and drain fixes.
The snag? Waiting for their quotes can take days. Post-work cleanup needs some improvement, too, especially compared to their competitors on this list who handle it thoroughly.
Back to the positives: their waterproofing fees align with Canada’s regular rates, and estimates don’t require extra payment.
Aquatech’s project consultants are dependable, as well. A friend of ours worked with a few, like Nico and Eric, and she found them responsive, well-informed, and polite.
Professional
‘I got 3 quotes from 3 very reputable companies. Aquatech not only came in the lowest but gave the most concise and useful information. Andrew didn’t try to over or fear sell. After the floods of July 16 we could probably be convinced to buy ANYTHING, but Andrew was honest and completely delivered what he and Aquatech said they would and in a great and professional manner! I would recommend Aquatech 100 percent with no qualms!’
-Rob V, Google Review
Very Knowledgeable, Punctual and Easy to Reach
‘Aquatech recently came to repair a crack in our foundation that we discovered during the July flooding in our area. Shawn attended for the quote and was very knowledgeable, punctual and easy to reach for follow-up questions. I had 5 companies come for quotes and while not the cheapest, they were fairly priced and had wonderful reviews and most importantly stand by their work in terms of a warranty.
Two associates came to do the repairs as discussed. They were quick, polite, respectful and very clean with the work area protecting both my home and my neighbours. They also showed me photos of the two cracks that were repaired. While it took several weeks to come and do the repairs it was understandable taking into account how many homeowners were impacted by the summer rain.
Overall, I was very satisfied with the experience with Aquatech. While I can’t speak to the quality of the repair until most likely the spring I was very comforted by the lifetime transferable warranty that was provided to me and would recommend Aquatech to friends and family for any waterproofing needs.’

RCC Waterproofing Toronto
Address: 129 Lytton Blvd
Contact Details: +1 416-747-1920
Operating Hours: Daily – 24 hours
RCC Waterproofing Toronto is the longest-running contractor on this list, operating since 1920.
They owe part of their success to reliable follow-through. Many clients confirmed that RCC will provide a date of completion (typically 3 days–1 week) and deliver on time, sometimes even quicker.
However, the downside is you must be patient when they’re busy, as it extends the estimate significantly. More complex tasks, like foundational repairs, can take up to 6–8 weeks.
A deposit is also required, meaning you pay upfront and still wait.
The good news is they’ll be clear about it and won’t overpromise.
That brings us to RCC’s other strong point—communication. Their specialists get kudos for prompt, simplified, and transparent responses, particularly over the phone.
In terms of services, they have the essentials like basement, interior, and exterior waterproofing.
Beyond Satisfied with the Results
‘I had the pleasure of having Chris IAC work on a waterproofing project in my basement this week, and I can’t recommend him highly enough. As someone who isn’t very knowledgeable about this type of work, I really appreciated how Chris took the time to explain everything to me in detail. His communication was fantastic—clear, timely, and always friendly. He went above and beyond to ensure the project ran smoothly, proactively addressing any issues that came up along the way. Not only was he efficient and highly skilled, but his dedication to getting the job done right really stood out. Chris made sure I was informed every step of the way, and I felt confident in his ability to handle everything. It’s rare to find someone who combines expertise, excellent communication, and a great attitude like he does. I’m beyond satisfied with the results and would definitely hire him again for any future projects.’
-Mitch Chenier, Google Review
Very Knowledgeable and an Excellent Communicator.
‘I have used RCC for multiple waterproofing projects. They are always very professional and thorough with their work. Daniel is very knowledgeable and an excellent communicator. Working with them is a breeze. Darwin and his crew finished the job with a high quality standard and even an eye for detail, they cleaned the site after the work was completed and even provided pictures of the progress and process. Highly recommend RCC for all your waterproofing needs.
