Liam SmithI’d love to call a basement renovation contractor soon, but it isn’t exactly in my budget right now. At the moment, I’d just like the floor to stop feeling suspiciously swamp-adjacent!
The best basement waterproofing in Ottawa can tackle leaks, dampness, and musty smells before they become pricier problems. That’s especially helpful when heavy rain decides to test every crack in the foundation.
The right contractor can recommend practical fixes without pushing a complete overhaul. Here are local picks that can help keep your basement drier and your savings intact.
How much does basement waterproofing cost in Ottawa?
Basement waterproofing in Ottawa typically costs $3,000 to $35,000 or more.
Interior waterproofing ranges from $3,000 to $12,000. Exterior waterproofing costs around $10,000 to $35,000.
Foundation crack repairs are cheaper. Expect to pay about $400 to $1,500 per crack.
1. Ottawa Foundation Repair
Address: 82 Ladouceur Street
Contact: Office: (613) 699-1920 | Direct: (613) 220-3553 | [email protected]
Hours: Mon to Fri 9 AM to 5 PM
I like that Ottawa Foundation Repair doesn’t just patch a leak and hope for the best. Their Building Science background helps them pinpoint why water’s getting in before recommending a fix.
They use carbon fibre countersunk staples to reinforce cracks against Ottawa’s freeze-thaw pressure. That’s reassuring when winter already seems determined to bully every foundation in the city!
Their exterior work comes with a transferable 25-year warranty, which adds solid long-term value. Detailed printed quotes also make the costs easier to understand.
The downside is that free estimates are limited to known issues. And their low-pressure injections aren’t suitable for hollow block walls.

Quick Response and Excellent Crack Repair
Yousef was great to work with. He responded to my call right away, and we were able to easily set up an appointment with him to fix the cracks in our foundation. He is very reasonably priced and did excellent work. He went above and beyond my expectations. Even after his work was done, he texted us a week later, after another heavy rainstorm in Ottawa, to make sure our basement was dry, which it was. I would highly recommend Ottawa Foundation Repair to anyone who is looking to fix their foundation problems. Thank you, Yousef:).

2. Braden Foundation Construction
Address: 532 Montreal Rd, Suite 366
Contact: [email protected] | (613) 880-8906
Hours: Mon to Fri 9 am – 5 pm, weekends: email to confirm
A wet basement in an older home like my parents’ two-storey can feel like one more expensive surprise hiding downstairs. Braden Foundation Construction makes that less intimidating with over 20 years of local, family-run experience.
They handle both interior and exterior waterproofing in Ottawa, so you’re not stuck with a one-size-fits-all fix. Their 35-year guarantee also adds some welcome reassurance when every repair dollar counts.
I like that they work with several foundation types, including older stone and rubble walls. That experience can be especially valuable in homes with a few decades under their floorboards.
The catch is that stone or rubble foundations may need structural work before waterproofing begins. Their mostly weekday hours can also make weekend scheduling tricky.

Full Foundation Waterproofing with Lasting Results
We had our entire west-Ottawa house foundation waterproofed. Al’s crew were hard workers and good-natured throughout. The foreman, Ryan, kept in touch with us from the estimate through to several months afterwards to make sure we were happy. The price was kept to, despite obstacles that the crew uncovered in the excavation. After years of dampness in our basement, there’s not a hint of it now. Thanks for your excellent work. I fully recommend Braden Foundation.

Professional Crew and High-Quality Basement Waterproofing
Thank you for a fantastic job waterproofing our basement foundation. We had a few contractors give us their opinion and a quote to repair our leaky basement. When Ryan came to assess our problem, I knew immediately that we were in good hands. From Ryan to the whole crew, everyone was professional, respectful and friendly. Very hard-working crew, safe and careful. High-quality work. They finished in a timely fashion and left our property clean. We are confident that our basement will now remain dry. I highly recommend Braden Foundation. A+

3. Tierney Foundation Repair
Service area: Ottawa, Ontario
Contact: [email protected] | (613) 276-7261
Hours: Mon-Fri: 8 AM – 6 PM, Saturday: 9 AM – 4 PM
I like that Tierney Foundation Repair still feels genuinely local instead of overly corporate. Founder Sam Tierney remains involved in the family-run business, which adds a more personal touch.
Their 24/7 emergency service is especially reassuring when a leak decides to appear at the worst possible hour.
A past customer I interviewed also praised their clear quoting process and fast response.
You’ll receive a detailed, free estimate, so there’s less chance of surprise costs creeping in later. That kind of transparency matters when you’re already bracing for a basement repair bill.
The downside is that some repairs may need several systems, including vapour barriers and sump pumps. Their service area is also heavily focused on Ottawa, so homes a bit farther out may need confirmation first.

Clean, On-Schedule Basement Leak Repair
I had an excellent experience with Sam & his team. Had a slow leak in my basement that desperately needed attention. The team were professional, knowledgeable, and took the time to explain every step of the process. They completed the work on schedule and left the site clean and tidy. I’m very pleased with the results and would highly recommend their services to anyone needing foundation repairs

Efficient Waterproofing and Sump Pump Installation
I had my sump pump and waterproofing system installed by Tierney Foundation Repair, and I couldn’t be happier. The team was professional, punctual, and explained every step clearly. The installation was clean, efficient, and the basement has been completely dry ever since. Highly recommend them if you’re dealing with leaks or foundation issues in Ottawa!

4. Renco Home Improvements
Address: 1178 Checkers Rd
Contact: 1.613.859.9006 | [email protected]
Hours: Mon to Fri 8 AM–8 PM, Sat to Sun 9 AM–5 PM
Renco Home Improvements lets you skip the runaround and speak directly with owner Terry Frasert. That kind of hands-on involvement usually makes communication much clearer.
Their fixed-price estimates are especially helpful when you’re trying to keep a basement repair from wrecking the budget. Plus, they offer a lifetime transferable warranty that adds even more long-term peace of mind.
They handle leak repairs alongside broader renovation work, which can be useful if your basement needs more than waterproofing. It also means one contractor may be able to manage several parts of the project.
The catch is that Renco isn’t solely focused on foundation repairs. Larger permanent changes may also require extra city permits, which can add time and paperwork.

Prompt Foundation Crack Repair Service
After a few days of heavy rain, I came home to find water in the basement and discovered a crack in the foundation. I contacted Renco and Terry got back to me the same day. He was available to inspect the site the following day and gave me a quote. He scheduled the job in less than 2 weeks. The technician, Lindsay arrived on time, was very professional and did a fantastic job sealing the crack. I highly recommend Renco for any home repairs.

5. Mr Foundation Inc.
Address: 98-5460 Canotek Rd
Contact: 613.746.7300 | [email protected]
Hours: Mon to Fri 7.30 AM to 4 PM
Ottawa winters don’t exactly pause for foundation problems, which is why Mr Foundation Inc. caught my attention. They use power blankets to thaw frozen soil, so repairs can keep moving even in January.
This family-owned team has been around since 1992, giving them plenty of experience with the city’s less-than-gentle weather.
They also provide written quotes within 48 hours, which helps when a basement leak is already testing your patience.
What I like most is how their crack repairs come with a transferable 10-year warranty. That’s a reassuring perk when you’d rather not pay for the same problem twice.
The catch is that free evaluations come with restrictions. Realtors and people actively buying or selling a property won’t qualify.

Professional Foundation Repair That Exceeded Expectations
Mr Foundation recently completed work at my mother’s home. She had water in the basement due to an exterior foundation issue. From the onset, the team was extremely professional. Mr Foundation went above and beyond to keep my Mom informed regarding the steps they needed to complete and the associated timeline to finish the job. The job site was left extremely tidy after each work day. When the job was completed, the work exceeded my Mother’s expectations. Mr Foundation’s work is second to none.

Honest Basement Leak Inspection and Recommendation
Matt from Mr. Foundation inspected two water leaks in my basement.He said one issue was a plumbing problem. The other issue was a garage roof problem. I truly appreciated his honest opinion and the fact that he did not take advantage of the situation to make money. I highly recommend Mr. Foundation!
