After comparing quotes from three different companies, we went with Dmytro and his crew at Willfix Inc. for our underpinning job. Our basement ceiling was cramped, barely hitting 6 feet, but now it’s a spacious 8 feet thanks to their hard work. Throughout the project, Dmytro and his team were great at keeping us in the loop and explaining everything in plain language. What really blew us away was how smoothly Dmytro handled things when we decided to add an addition halfway through the projcect. Despite the unexpected twist, Dmytro made it work without a hitch. And, true to his word, the project stayed on budget and finished right on schedule. We’re over the moon with the results and would definitely recommend Dmytro and Willfix Inc. for any underpinning job, big or small.

  • NO loss in structural soundness;
  • NO wall cracks and water damage;
  • NO broken wires or plumbing issues.

We have certified engineers and experienced craftsmen on our team for a reason: when we say it’s flawless, you can expect it to be so. And our reputation proves our point even better.

A dry and well-maintained basement significantly boosts the resale value of your home. Potential buyers in Toronto are often wary of water damage and related issues, so a waterproofed basement is a strong selling point.

Top Rated Service

Persistent moisture weakens the foundation and structure of your home. Basement underpinning and waterproofing safeguard against this, ensuring the longevity and safety of your property.

Protect Against Harsh Weather

Toronto experiences varying weather conditions, resulting in freeze-thaw cycles that weaken the concrete of your foundation. During underpinning, we prepare and protect your basement against such unpredictable weather patterns.

Each project showcases our commitment to quality and customer satisfaction. From minor cosmetic issues to reinforcing foundations, our work improves both functionality and value.


    The short answer is — yes, it’s worth it. Your main motivation can be different, but we believe that NOT having leaks is the most popular one. A leak, even if it’s a minor one, can cause extreme trouble. The water can damage your belongings, and you never know, what will get damaged: something cheap or that one most expensive item that you have in your basement? Given that Murphy’s law works, we are afraid to even try to predict. Besides, basement waterproofing makes your house a horrible, uninhabitable area for mold and insects. These two hate dry areas with normal humidity, so they won’t ever appear in a properly waterproofed basement. No mold — no allergies and smell — no health issues for you and your family.

    Each basement is unique, so it is not about the property above it but about soil and other personal circumstances in and around it. The only difference may be that commercial basements are bigger and are more expensive to underpin and waterproof. We perform the best basement underpinning in Toronto and GTA, regardless of property type.

    The first and most popular reason is to increase the space in it. We can raise your basement ceiling and turn previously unused spaces into a gym, home cinema, or simply an additional room, which you can rent out and earn a consistent extra income. We can also make a walkout basement, so your guests will have their entrance to avoid disturbing you too often. Our experienced basement underpinning contractor also checks plumbing and applies additional waterproofing measures, so you can forget about moisture issues for years to come.

    The best time to perform basement underpinning is during dry seasons, typically in late spring, summer, or early fall. Dry weather conditions are ideal because they reduce the risk of water infiltration during the construction process. Additionally, warmer temperatures allow for better curing of concrete and other materials used in the underpinning process. We ensure minimal disruption and optimal results regardless of the season. Contact us and book an appointment at any time convenient for you!

    Homeowners insurance is a complex legal document. So it is better to ask our experienced underpinning contractors on this matter. They will advice you wether you need to update your old insurance or declare subsidence.
