The 9 Best Foundation Repair in Ottawa

Even the sturdiest foundations need a bit of repair sometimes. If you’re dealing with a flooded basement or large cracks in the walls, now’s the perfect time to have it repaired by one of the top foundation repair contractors in Ottawa!

We’ll give you a list of our best suggestions along with a few pointers to look out for when hiring them, as well as answers to some FAQs.

What to Know Before Doing Hiring Foundation Repair Contractors

Foundation repairs tend to be quite expensive and therefore, you should only have them done by the right people at the right time. Here are a few guide questions to help you get started:

1. Are the repairs really necessary?

You want to make sure you get a second or even third opinion when it comes to having a professional over to have a look. It’s not far-fetched to believe that some companies are willing to repair minor cracks that don’t really pose any issues just to make a quick buck.

Make sure that the companies you’re hiring are trustworthy. If all three opinions agree that foundation repairs are needed, then that’s when you should have a job done.

2. How long have you been in this business?

Foundation repair is a tough business to be in, and the general rule is that the longer they’ve been around, the more you can trust them. This is especially true since many of them offer lifetime warranties, and you want to be able to hold them to that.

3. Are you fully insured?

In a business that requires a lot of heavy lifting, machinery, and well-trained contractors, insurance is non-negotiable. Workers and yourself must be protected at all times from damages to your person, family, and property.

On the extremely rare occasion a foundation repair provider doesn’t have insurance, just walk out the door.

4. Can I see some references?

There’s nobody that stands to gain from a company’s services more than other homeowners and business owners. They tend to be much more honest about the contractor’s quality of service compared to ads paid for by the company itself.

Take the time to ask about the company and if there are any red flags you need to look out for. Remember that a good company will be more than happy to share testimonials from past clients!

How Much Does Foundation Repair Cost in Ottawa?

It’s very difficult to estimate the costs of a foundation repair job without being able to assess the problem. The factors for cost include the type of problem, location, severity, and the solution needed to fix it.

Luckily, the foundation repair contractors we’ve listed here all offer free estimates, all you need to do is give them a call!

Here’s what EC Foundation’s satisfied clients have to say about their experience working with the company:

The job site was kept so clean each day

Scott and his team’s work on our home was excellent.  His proposal was very detailed and the approach they would be taking was explained in a way that was understandable since I don’t have much experience with this type of work.   The job site was kept so clean each day, the crew was there for about a week.  Scott was honest and always returned my calls when I had question.  Recommended them to my parents who also ended up using them and were equally as happy!” – Andrea P

Very happy with the service provided

“After calling several companies, we contracted them because they quickly  and thoroughly identified our issue. They were very professional, and completed the work exactly as they described.

Customer Reviews

Here are some comments left by previous clients:

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.

“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!”

Has a professional approach

“When we discovered foundation problems with the 110 year old house which had been covered up by a previous owner, we contacted Action Restoration. Patrick responded immediately and we had a contract in place and work commenced within days. Patrick kept us informed of the progress and issues. Their skill and experience helped deal with problems as they arose and the work was completed in less than 2 months. Patrick cares about his clients, has a professional approach and takes pride in the work of his company. I have no hesitation in recommending Action Restoration for any restoration project.” — Yvonne

Professionalism and pursuit of perfection were commendable

“We engaged the services of Action Restoration for foundation repairs and the installation of support posts to fortify the wood beam. Patrick and his team executed the project with excellence, displaying both efficiency and a friendly demeanor while working on our home. Their commitment was evident as they commenced work early each day, with Patrick occasionally arriving ahead of schedule, patiently awaiting our door’s opening. A noteworthy aspect was their consistent practice of tidying up the work site daily.

Patrick’s professionalism and pursuit of perfection were commendable. From the outset, he visited our home, providing a thorough explanation of the required scope of work, outlining the anticipated timeline for completion, and presenting a transparent estimate of costs. As the project unfolded, any additional work needed prompted immediate notification from Patrick. He not only clarified the reasons behind the added tasks but also presented us with various options for consideration. The team’s diligent efforts ensured timely completion, and we appreciated the continuous communication, meticulous attention to detail, and the respect shown to our home throughout the entire process.

Our heartfelt thanks go out to Patrick and Team Action Restoration for their exceptional work! We wholeheartedly recommend Action Restoration to friends and neighbors seeking a trustworthy and professional foundation repair team. Their dedication to quality and customer satisfaction sets them apart, making them a reliable choice for any foundation-related needs.” — Sarah
