But if you’re wondering how much these services will cost you, we’ll tackle them shortly. After that, we’ll be giving you our top options and discuss them as well to help you pick the right one.

The Average Cost of Foundation Repair in Ottawa

Foundation repair costs in Ottawa vary for each homeowner as they depend on the extent of foundation damage and the current condition of your home.

Now, most people spend between $300 to $50,000 to get their structural problem resolved, whether it be related to cracks, basement leaks, or one that requires excavation work.

To give you a price overview, please refer to the table below based on the data of Ottawa-based foundation contractor, Renco. Note that other companies may charge a lower or higher price than the amounts shown below.

Foundation Damage WorkCost Range
Foundation inspectionFree – $300
Non-structural crack repair$950 – $2,650
Structural crack repair$1,200 – $1,700
Exterior foundation crack repairFrom $5,000

To get an accurate estimate, you’d have to book an appointment for the team to take a look at your property’s foundation. Get at least three quotes from different contractors to find the best price.

However, bear in mind that the lowest price isn’t always the best because the company’s work quality might be compromised due to that.

Ask for references and ensure that these come from legitimate clients or business owners. Most of all, you have to check the contractor’s licences and insurance and if they are authentic, since your home’s safety is also important.

If you want to know what EC Foundations’ previous clients have to say about them, then look no further:

Complete and thorough foundation repair

Thanks for the excellent work your company conducted at our home. The work involved the repair of the garage floor, foundation walls and footings. This necessitated the complete excavation, soil inspection, enlargement and dowelling of new footings, drain tile installation, steel plate tin-in reinforcement procedures, grouting of cracks, waterproofing, crushed stone backfilling and pouring of a new mesh-reinforced slab floor. We sincerely appreciate your knowledge, professionalism, honesty and integrity in conducting a complete and thorough foundation repair.” – Brian Moyes

Extremely knowledgeable, clean, and professional

“We hired EC foundations to underpin and waterproof our foundation. Scott and his crew were exceptional – easy to speak with, extremely knowledgeable, clean, and professional at every turn. They patiently answered our many questions and spent time walking us through the repair process. Scott and his crew addressed the inevitable surprises that come with such projects calmly and fairly, which we found very reassuring. They handled the city permits, inspector visits and engineer reports. Scott took time to meet with our neighbour to ensure they had a full understanding of how the crew would protect their property. They also took care of setting up the piles for additional structures we planned to build after the foundation work was complete, which saved us a lot of time. Scott and his team were here every day, provided daily updates, and delivered exactly what they said they would do. We would recommend EC Foundation without hesitation.” – Caroline Quesnel

It received rave reviews from clients who mostly noted their stress-free service process, honest and respectful staff, and superb repair work. They were given a 4.9/5 star score on Google.

One of their clients wrote this as can be read on the website:

“Chuck Naish and his team from City Residential Foundation Repair were excellent to deal with in every aspect. Their level of integrity throughout the entire process was outstanding. They were honest, respectful and their ability to explain the process and the solution options were extremely helpful to us. The scope of the project was big, however Chuck walked us through every step of the way; assessment, testing, options and repairs which resulted in a very successful outcome. In addition, Chuck and his team were able to complete the necessary repairs with minimal impact to our newly completed landscaping which included a lot of hard scape, tiered armour stone, gardens and a pool. They kept the work site impeccable over the duration of the project. We have and will continue to highly recommend Chuck Naish for his very professional and skilled foundation repair work.”

Check out this one from another happy client:

“I would have no hesitation in recommending City Foundation. They fixed up my foundation last summer and although the old house produced a few surprises, the professionals at City Foundation got around the problems cheerfully and completed the work. From the start, Chuck kept me informed of all of my options. If I asked for something not already in the plan, he would try to accommodate me if at all possible Chuck and his colleague Don were friendly, and respectful. They showed up every day, put in a solid day’s work and always left the property clean, neat and safe for us to move around. And, the price was fair with no surprises. Great guys, good job!”

He’s such a nice guy, cares deeply about his clients, and bends over backwards to make it right. I will have him back to do more before it becomes a problem this time.

Customer Reviews

The company bagged a perfect score on Google. Most clients complimented their honesty, professionalism, and consistency in their work and treatment of them.

Here’s the feedback of one client named John:

“I was very pleased with the work done by The Foundation Experts in 2017.  The work was done quickly and professionally by Alex and his team.  I especially liked that they did not have multiple jobs on the go, they focused on my home until it was done as agreed and then moved onto the next customer. I felt that my satisfaction with the work was their top priority.  We ended up selling the house a few years later and the lifetime transferrable warranty was very appealing to our buyers.  Thank you Alex!”

And Joy opined of the foundation contractor:

“Alex and his team gave us excellent advice throughout this multi stage project. Work kept to schedule despite Covid’s attempts to create problems. We are very satisfied that the foundation is now secure and safe. The team to have when you need expert advice, high quality work and the security of knowing the job is done right.”
