Editorial Review

Our Take on Ottawa Foundation Repair

Ottawa Foundation Repair earns its place on the strength of a 25 year transferable exterior waterproofing warranty and consistent praise for clear, fairly priced crack repairs. The mismatched address between its site and Google, and the lack of stated insurance or WSIB details, are the points to settle before signing.

  • Al M5.0

    Yousef was very professional and provide great service and an upfront price. He explained everything that he was doing and had the work completed in a few hours. I highly recommend Ottawa Foundation Repair and Yousef's work.

  • Kal Elfarro5.0

    ⭐⭐⭐⭐⭐ I can’t say enough good things about Yousef and his company. We contacted him after experiencing significant water damage at our home, and from the beginning he was knowledgeable, honest, responsive, and extremely easy to deal with. What I appreciated most was that Yousef took the time to properly assess the situation and explain what was happening, what needed to be done, and why. There was never any pressure or attempt to upsell unnecessary work. He was straightforward with his recommendations and genuinely seemed more concerned with making sure the problem was fixed properly than simply getting the job. The quality of the work was excellent, communication was great throughout the process, and everything was handled professionally from start to finish. Having worked in construction myself for many years, I have a pretty good idea of what good workmanship and good customer service look like, and Yousef delivered on both. It’s difficult to find contractors you can genuinely trust, especially when dealing with something as stressful as water damage to your home. Yousef is one of those people I would have no hesitation recommending to friends or family. Thanks again, Yousef. Great work and very much appreciated.

  • The Critical Eye5.0

    I had an excellent experience with Ottawa Foundations Repair. The team was professional, knowledgeable, and completed the job much faster than I expected without compromising on quality. They kept me informed throughout the process, left the work area clean, and the finished result was outstanding. It's clear they take pride in their work and genuinely care about their customers. If you're looking for reliable foundation repair done right, I highly recommend Ottawa Foundations Repair. Thank you!

    I messaged them about a window well needing to be hand dug because of our deck. This was their response. Sarcastic and unprofessional. We have a flooding basement and they respond with sarcasm. If you can't do a job just say so. I'll keep posting this every few weeks. This is a terrible response to a client in need. I called 10 because I wanted to know if anyone could get here in under 2 weeks. Here's photos of my 'scam basement' My business is not a scam, this is my home and you treated my ask for help like a joke.

  • Kim Delis5.0

    We requested a quote to assess how the foundation could be waterproofed and to determine whether any existing cracks were a cause for concern. He took the time to thoroughly explain his findings and what I need to monitor, and he answered all of our questions. It was also interesting to learn about their innovative methods for foundation repair and the extensive warranties they offer. Based on this experience, we would definitely choose this company for any future foundation repairs.

  • Nathalie Mulder5.0

    Highly recommend this company. Yousef was referred to me by my real estate agent to fix a crack in my foundation. I was not disappointed, Yousef fixed the crack the next week. Very professional and reasonably priced .

Company Background

About Ottawa Foundation Repair

Ottawa Foundation Repair puts a 25 year transferable warranty on exterior waterproofing in writing on its own website, a longer term than many homeowners see quoted elsewhere, with 15 years on interior crack resin injections. The company works from 14 Mayo Avenue in Nepean, in Ottawa's west end, and its site names Ottawa, Kanata, Orleans, Stittsville, Carp, Cumberland, Vars, Embrun, Rockland and Metcalfe as places it serves. Its pages cover wet basements, damp basements, exterior excavation waterproofing, weeping tile, sump pumps, window wells, crawl space waterproofing, epoxy and urethane crack injection, house leveling and foundation stabilization, with commercial work listed too. The company describes itself as a BBB member and says its team has an academic background in Building Science.

The reviews lean toward crack work and plain explanation. Brent describes a crack in a poured foundation repaired by injection in about three hours, with Yousef talking him through each step. Sandra had four cracks fixed under a 15 year warranty after another company quoted four times the price. Eric reported in 2025 that a corner excavated to the footings, patched and reinforced in October 2023 had stayed dry. Ottawa Foundation Repair holds 4.8 from 100 Google reviews, read October 21, 2026, and it sat first in the Google Maps results we checked.

The fair caveats are practical. The website lists 82 Ladouceur Street while Google shows 14 Mayo Avenue, so confirm where the crew is based when you book. The site does not state a founding year, licence numbers, insurance or WSIB coverage, and free estimates cover obvious or known problems inside Ottawa, with a fee possible for a full investigation if the job does not go ahead. Hours are weekdays only.

It suits homeowners with cracked poured foundations, seepage through a crack or a damp basement who want a long transferable warranty. It suits less well anyone who needs weekend or emergency service, or a large interior drainage retrofit, which the site does not describe in detail. Ontario has no waterproofing-specific licence, so before booking ask for a WSIB clearance certificate, proof of liability insurance and a written permit plan with the City of Ottawa where one is needed, and check the business on the Ontario Business Registry. Ask to see the 25 year warranty in writing and confirm what transfers to a buyer.

Ottawa Foundation Repair FAQs

    Google lists Monday to Friday, 9 AM to 5 PM, and the company is closed on weekends. The website header shows 9 AM to 6 PM on weekdays, so call to confirm. The site does not mention 24 hour or emergency call-outs, so ask directly if water is entering your basement outside office hours. The direct line is (613) 220-3553.
