Customer Reviews

“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!”

“We’ve never dealt with foundation repairs before, but the service we got from Scott, Nicole and the rest of the team were superb. They are responsive with any questions or concerns, and are very accommodating. I highly recommend going this company.”

Customer Reviews

We are so happy with the workmanship and prompt service we received

“We had a serious problem developing with the sunroom attached to the back of our home. It was probably 15 years old or so and over the years was sinking :~( I contacted René, the owner and he came right over the next day. He told me he could solve our problem and gave us a price that seemed very fair. His team came over on a Friday and finished the job the next day. They had the equipment needed and raised the room back to its original position, installed steel beams and the right kind of helix foundation supports so the room will never sink again. Magical! We are so happy with the workmanship and prompt service we received from René and the team at Ultimate Foundations Repairs. Give them a call and let them do their magic on your foundation repair needs.”

A certified foundation repair expert, Ottawa Foundation Repair can help you with your waterproofing needs. Its BBB accreditation gives us more reasons to believe in the quality of service it provides its customers. 

The company specializes in various services, which include exterior waterproofing, crawl space waterproofing, wet basement restoration, and concrete crack epoxy/urethane injections. 

Although limited, we like that its exterior waterproofing and interior crack resin injection services come with 25-year and 15-year warranties, respectively. If any leak occurs within the warranty period, its team will repair things free of charge.

The best part here, though, is that these warranties are transferable to new owners, adding value to your home.

We like that its team is composed of qualified and educated contractors with years of academic background in building science and hands-on construction experience. With skilled personnel, we trust its promise to get things done right the first time. 

Another thing that caught our attention is its use of a thermal imaging scanner to detect active water leakage from foundation walls and basements. With it, no invasive investigations are needed.

We appreciate that its website contains a gallery, which potential customers can use as a reference. Also worth noting are its crew’s responsiveness, professionalism, and efficiency. 

Pros

  • An array of services offered
  • BBB accreditation 
  • Transferable warranties
  • A team of qualified contractors 
  • Thermal imaging scanner

Cons

  • Warranties are limited to some services 
  • Closed on weekends

Fast, informative, and reliable

“Highly recommend Yousef’s work, which is fast, informative and reliable.  I got panic when seeing my basement wall leaking after the rainy but frozen night last Saturday, but when I talked to Yousef, I was much relieved. He is highly professional and patient. Yousef is also a nice guy who treat his customer like a caring neighbor. His charge is reasonable.” — Bear Mr., Google Reviews

No more leaks

“Yousef and his crew were friendly, professional and fantastic to work with.  The job was completed on time, on budget, and best of all, no more leaks!  I would definitely recommend going with Ottawa Foundation Repair.— Erin Gillespie, Google Review

Fully licensed and insured, City Residential Foundation Repair is a good choice when looking for professional waterproofing services. With an A+ BBB rating, we trust that it will render quality work. 

Currently, it specializes in providing customized, cost-effective treatments which include basement waterproofing, construction waterproofing, and interior and exterior waterproofing. Other services include crack injection and sump pump installation.

One of the things we like is that its team uses Armtec Platon membrane in their waterproofing services. This special type of membrane is made from eco-friendly, high-density polyethylene (HDPE), which is perfect for the environment. 

To ensure optimal waterproofing, this membrane is matched with a new weeping tile, which is wrapped with a sediment filter and a frost-free backfill. 

We also appreciate that the company offers free consultations and estimates that often come with competitive rates. If you’re busy, setting a same-day appointment with the contractors who are always prepared might just work for you.

There’s a photo gallery, too, which is a nice way of providing customers with an idea of what its team is capable of. The only downside we found is that there were no price guides provided for customers to use as reference. 

Since the company is closed on weekends, you might also need to allot time for its services on a weekday. But other than this, we think that City Residential Foundation Repair is a good start for waterproofing needs.

Pros

  • Different types of related services 
  • Fully insured and licensed
  • A+ BBB rating
  • Customized treatment
  • Eco-friendly materials
  • Free estimates and consultations

Cons

  • No price guides provided
  • Closed on weekends

One of the reasons we trust Renco Home Improvements for waterproofing needs is that it has built a strong reputation in the industry for more than 20 years. Having a BBB rating of A+ further affirms our belief in it. 

As a trusted renovation company, it offers services that extend from basement waterproofing to bathroom renovations. Under its waterproofing services are exterior basement waterproofing, interior basement leak repair, and sump pump installation, among others.

Apart from following a proven step-by-step basement waterproofing process, we like that Renco Home Improvements uses Blueskin waterproof membrane. Made of rubberized asphalt and polyethylene, this provides consistent waterproofing protection. 

We also appreciate that its team ensures order and cleanliness around the property after every project. And to help you become more confident with the quality of materials and workmanship, the owner provides a 25-year, transferable warranty on all projects. 

You might also want to take advantage of its free appointments, which are great for design ideas, estimates, and timelines. The gallery on the website is great as it provides visuals of the team’s previous work. 

On top of having no price guides, communication mix-ups can sometimes happen. Especially when things get busier, sending follow-ups might be necessary in cases of delayed responses.

Pros

  • A variety of services offered
  • A+ BBB rating
  • Blueskin waterproof membrane
  • 25-year service warranty
  • Free estimates 

Cons

  • Communication can be improved 
  • Closed on weekends

Customer Reviews

Beyond expectations

“Renco just finished repairing some water leaks in my kitchen nook area and crack in my basement foundation.  Terry is the face of the company, very friendly, knowledgeable and overall amazing to deal with. His crew was extremely courteous, meticulous and professional.  Having lived in my house 13 years with this problem from the start, both the builder and another contractor could not figure out the problem causing the leak.  Terry did a quick inspection, found the problem, fixed the area leaking and recommended a wait period to ensure no more water entered. His crew repaired all the interior damaged areas beyond expectations.” — Stephen Sterling, Google Reviews

Happy with everything 

“Highly recommend. We had Renco repair a small foundation crack. We were happy with everything from start to finish. Would definitely use this company again in future. Thanks Terry and team!” — Penny Tait, Google Reviews

The Foundation Experts Inc. has been in the business since 1995, and this is one of the reasons we trust it for waterproofing needs. Alongside more than 20 years of experience is its A+ rating from BBB.

At present, it offers services that include waterproofing, foundation restoration, and other structural repairs. For its waterproofing services, it employs the use of Air Gap Technology, which allows moisture and water to freely exit walls.

It’s great that it is fully insured and that the employees are licensed with the necessary technical training for waterproofing in Canada and the US. We also appreciate how the owner takes the time to supervise all operations to ensure quality control. 

We like that all projects come with transferable warranties. The only downside here, though, is that there are no details provided on the website, and calling the company is the only way to get the information you would need.

We appreciate that written estimates and references are provided to help customers better prepare for the costs. But since there are no price guides provided, make sure that the rates are discussed before closing the deal.

On a different note, we commend its team for always delivering services on time and within budget. Above all, we like that its people stay committed to excellent customer service through professionalism, punctuality, and responsiveness.

Pros

  • A wide array of services
  • A+ BBB rating 
  • Fully insured and licensed 
  • Transferable warranties
  • Air Gap Technology

Cons

  • Limited info about warranties
  • Closed on weekends

Customer Reviews

The team is always there

“When I found cracks in my foundation I called The Foundation Experts and they were quick to come and assess the problem. Alex was great in explaining to me the problem, and explaining in detail the type of work that would be done. Big jobs like this can be stressful but Alex and his team reduced that stress by making things go as smooth as possible. Being given a breakdown each day as to what was going to be done was great, and the team were always extremely friendly and hard working. The Foundation Experts truly are working for you in fixing your home and the team is always there for any questions along the way. Thanks again for making this project seamless and smooth!” — Jeff Lavery, Google Reviews

Committed to service excellence

“After buying our forever farm property my wife and I knew that a new water proofing foundation would be required. Alex and the Foundation Experts impressed us from the beginning and remained committed to service excellence throughout. Always punctual, even if our property is in Woodlawn, Alex and his crew remained open to our questions and comments throughout. The job further remained on time and on budget. We would unequivocally recommend The Foundation Experts Inc crew to anyone we know.” — Olivier and Brigid Lynch, Google Reviews
