The other day, I woke up to my neighbor yelling outside about their basement turning into a mini swimming pool after a heavy rainstorm. Yikes!
It got me thinking—avoiding a soggy disaster like that is definitely worth looking into. Hiring basement waterproofing experts is the smartest way to keep your home safe, dry, and stress-free.
If you’re in Toronto and want to steer clear of basement woes, here are the best waterproofing pros who can help you protect your space without breaking a sweat.
How much does basement waterproofing cost in Toronto?
The cost of basement waterproofing in Toronto typically ranges from $80 to $250 per linear foot.
For a full basement, the total cost can run between $3,000 and $15,000 or more, depending on the size and the extent of the waterproofing needed.
Exterior waterproofing is usually on the higher end, while interior solutions like sealing or installing a sump pump are more affordable.
How We Chose the Best Basement Waterproofing Experts in Toronto
1. Aquatech Waterproofing

Aquatech Waterproofing has been around for over 25 years. As a privately owned, fully insured company, their goal is to keep Toronto homes dry without draining your wallet.
When it comes to interior waterproofing, these guys are pros. They offer seamless wall sealing to lock out moisture and install interior drainage systems that whisk water away before it becomes a problem.
For extra peace of mind, they also do sump pump installations to keep your basement water-free even when the weather gets wild.
And if you’re looking for exterior waterproofing, they’ve got that covered too. Sure, it’s a bigger job since it involves digging around your foundation, but we think the results are worth it.
Now, here’s the thing—some folks have mentioned that their response time could be better.
What an amazing company and group of people
“WOW! What an amazing company and group of people. We had water coming in our basement but it’s all fixed now. I get nervous doing big jobs like this but felt very confident with this whole process after talking with Aquatech. From our consultation with Tony, we got all our questions answered with patience, which we appreciated. He made us feel like any of our concerns was a good concern. Any time we had any questions we would give him a call and he was always there to help. The crew was amazing! In and out, clean and polite. Thank you Igor for doing the great job with your crew! And the closing with Nick was just a great way to end our experience! Will highly recommend!”

Work was completed in 4 days
“Shawn was informative, straightforward, and reliable. He visited the property, gave a quote and followed up quickly when there were questions. There was a wait of approximately one month before work could begin, due to their busy workload. When work started his team worked hard and efficiently. Work was completed in 4 days. At the end of each work day the area was clean and organized for the following day. When the waterproofing work was complete the area was cleaned up and the team ensured that everything was left in good order. Although I hope not to need their services again, I am confident that they would fix any problem that may arise. I highly recommend Sean and his team!”

2. Royal Work Basement Waterproofing

Royal Work Waterproofing is a family-run business that’s been in the basement waterproofing game since 1998.
We appreciate their free examination and estimate. They’ll inspect your basement thoroughly, pinpoint any water damage, and recommend the best solutions—all before you commit to anything.
For interior waterproofing, they remove moisture using drainage channels that lead to a sump pump, efficiently keeping your basement dry.
On the other hand, their exterior waterproofing involves creating a channel around the basement’s perimeter and polymer coating the walls to seal out water.
Pricing is pretty reasonable as well, starting at $80 per square foot—a solid option for homeowners on a budget. And as a bonus, they back their work with an amazing lifetime warranty!
Sadly, we did hear about ongoing leaks even after work was completed.
Efficient and exceptional company
“Royal Work Basement Waterproofing is an efficient and exceptional company. Their work was organized, timely and clean. Our concerns were not only addressed but listened to. We were assured the problem would be fixed and it was effortlessly. I highly recommend them. They are truly a 5-star rated company.”

Their guys did an amazing job— they explained every detail of the repair process and patiently answered all my questions. The service was fast, affordable, and left the space clean. Highly recommend their work!”

3. Direct Basement Waterproofing

Direct Waterproofing has been serving Toronto homeowners for over 25 years.
We like that they use only top-notch products like Delta membrane and Platon foundation wrap. These materials are not only highly impermeable but also breathable, providing a protective barrier for your foundation while letting moisture escape.
For interior waterproofing, they install drainage systems that shield your basement walls and create a moisture-resistant environment. Their exterior services are just as thorough, covering everything from sealing foundation walls to setting up drainage.
We’re also impressed with their 25-year transferable warranty—a major plus if you’re planning to sell your home someday.
And unlike other companies, they offer a 24/7 emergency response for sudden waterproofing issues.
Note that a few customers have told us about no-shows for appointments. We agree that this can definitely be frustrating.
Best quality work, best service, and honest price
“How can a waterproofing company receive such a high rating? After a week of Direct Waterproofing working at my home, I understand why. Best quality work, best service, and honest price. Terry and his team did an incredible job waterproofing our foundation, installing sump Pit/pump and back water valve in our home. Finished the job on time with no changes in quoted pricing. Took great care removing/replacing our landscaping and even scoped our sewer lines to insure weeping system was fully disconnected from internal drain.Terry even replaced the downspouts at no added charge. Would 100% recommend.”

Couldn’t be happier with the high quality of work
“I hired Terry and his Team (Roman and Walter) to do an external waterproofing job. Terry was extremely knowledgeable, professional and honest. He was so patient with all my questions and assured me every step of the way. His team did an excellent job and we couldn’t be happier with the high quality of work and they were punctual and followed through as promised. What an amazing experience, I’ve already referred them to my family and friends!”

4. Aquamaster

Aquamaster Basement Waterproofing Toronto has been in the game since 2009, helping both residential and commercial clients across Toronto and the GTA.
For interior waterproofing, they tackle cracks in walls and floors using high-quality sealants or epoxy injections, sealing off those pesky water entry points. They also apply multiple layers of waterproof coatings that keep water out for good.
We love that they back their work with a 25-year transferable warranty, giving you some serious peace of mind. Speaking of peace of mind, they’re available 24/7 for emergencies, which is great if a water issue pops up out of nowhere.
As a cherry on top, first-time clients also get a 10% discount!
Do watch out for abrupt cancellations of bookings, which can be frustrating if you’re on a tight timeline.
My waterproofing was done faster than promised
“Pleasure working with this company. True professionals in their field. My waterproofing was done faster than promised and the cleanup was astonishing. Like they were never there at all. Very happy and will recommend to all my friends and family.”

Amazing to deal with from start to finish
“Vasyl was amazing to deal with from start to finish. He has an honest and genuine approach to determining what needs to be done. He even lent me a couple of his tools after the job to let me fix something else after the job. He’s also come back a couple of times to check in and make sure things are working properly. Great guy, great company – would definitely recommend them.”

5. RCC Waterproofing

Serving areas from East York to Downtown Toronto, RCC Waterproofing is practically a Toronto legend since they’ve been keeping homes dry since 1920.
They offer a variety of solutions for leaky basements, including exterior waterproofing, interior waterproofing, and structural crack repair. And only top-notch materials like the Hydro Guard Pro Series (with a lifetime warranty) are used in their work.
Begin with their free estimate and inspection—they’ll help you figure out which services your basement needs, and their pricing is pretty reasonable too. For example, interior waterproofing can range from $50–$100 per linear foot.
However, we’ve heard that their inspections can feel a bit rushed, sometimes lasting just a few minutes. It’s worth asking for a detailed walkthrough to make sure all your concerns are addressed.
5 stars all the way from start to finish
“Words cannot express how happy I am with the work that was done by RCC to fix my crawl space after it started to leak in water. I received a very timely response back from Anthony after I called in. He was out the next day and went over the work that was required. I received a great quote within hours and the quote was very reasonable . The work was scheduled and done within a few weeks. The crew that came out was led by Darwin. He and his team were very friendly and professional. The quality of work was outstanding. They cleaned any mess made from removing concrete. Darwin explained to me everything that was done and how the sump pump worked. A shout out to Monica at the office that was available for any questions. 5 star all the way from start to finish.”
