J’ai fait appel à Sous-Sols Experts Inc. pour refaire le plancher de mon garage, et je suis extrêmement satisfait du résultat. ✅ Prix très compétitifs, surtout pour un service aussi complet. ✅ Pietro prend vraiment le temps d’expliquer chaque étape du projet, comment les travaux seront réalisés, et pourquoi. C’est rassurant et professionnel. ✅ Les travaux ont été faits de façon continue, sans interruption sur plusieurs jours consécutifs, ce qui était idéal pour moi puisqu’il fallait déplacer beaucoup de choses hors du garage. ✅ Projet clé en main : il s’est occupé de tout, même de la plomberie pour l’installation des drain. Contrairement à d'autres entreprises qui me demandaient de gérer mon propre plombier et de coordonner les travaux, ici je n’avais rien à gérer — un vrai soulagement. ✅ Même un excellent service après-vente : j’avais une préoccupation concernant une infiltration d’air froid, Pietro s’est déplacé rapidement avec son équipe. Le problème n’était même pas lié à leurs travaux, mais ils l’ont quand même réglé sur place. En résumé : service 5 étoiles, communication facile et efficace, et résultat impeccable. Je recommande sans hésiter! 👌

Pietro di Benedetto and Sous-Sols Experts provided the best possible solution to my foundation problems. The work included excavation of the rear foundation of my house, where water infiltration had begun, the construction of a reinforcing concrete wall against the existing foundation, the waterproof sealing of that new wall, the installation of a French drain and interior sump pump, and a refill of the trench with new gravel. He also provided me with a new drain at the bottom of an exterior stairwell that solved problems I’d been having for over thirty years. In my judgment, all of this work has been completed to a very high standard, and at exactly the price promised. Pietro prides himself on honouring his original estimates, even though a very slow permitting process with Plateau Mont-Royal meant that his original estimate was almost a year old when the work finally began. Pietro maintains a clean and orderly work site, even in the cramped conditions of my Mile End back yard. He laid down plywood on my lawn on the first day to keep machinery and heavy boots from damaging any exposed grass. After two and half weeks of work my garden had taken almost no damage, and only of a minor kind to be expected. He and his friendly crew cleaned up at the end of every day and very thoroughly at the end of the work. He was always ready to answer questions or clarify the purpose of a stage of the project. As his estimates indicate, he works on your project on consecutive days, although at the beginning and end of a project he naturally finishes up with the previous customer and prepares the work for the ensuing customer. He estimated two weeks of work and the job took close to three, but that included St Jean Baptiste and Canada Day holidays and a rain day, as well as the jackhammering of bedrock he was not expecting to deal with (this did not change his price). He and his crew often worked past 5:00 because a given stage of the work required it. Your neighbours might like to know that he does not start before 8:30 in the morning to avoid disturbing others with machinery noise. I should also say that Pietro was both patient and helpful as I navigated the permitting process with Plateau Mont-Royal. I was very glad that I chose Sous-Sols Experts for my foundation project. Pietro often talks about the customer’s experience: the work has to be done well, but the customer must also have a good experience of the total project’s completion. I had exactly such a good experience, and I’ll certainly be recommending him to anyone who asks me about their foundation job.

I was highly impressed with Sous-Sols Experts. Mr. Di Benedetto met his deadline, his team was courteous, did a good job, and cleaned up afterward. I am very pleased with the result. I strongly recommend them for any water-related issues.

Pietro is one of the most honest, trusting professionals that I have ever come across in my life. His work is impeccable and I cannot emphasize how pleased I am with the outcome of my newly renovated garage floor, sump pump and new drains. It was a bigger job than anticipated but Pietro was very reassuring and in the end, it’s all done and done to the highest of standards. There was no cutting corners and no BS . Thank you Pietro for all you have done , you are appreciated by me and my family.

Pietro and his team recently did work at our property in Laval. They demolished the deteriorating cement gallery, stairs and walkway and proceeded to rebuild it all better and stronger than ever! The end result is fantastic! Our expectations were surpassed. Pietro is a man of his word!! Thank you 🙏

Après le déluge de ouragan Debby en 2024, notre sous-sol était parfaitement au sec et c'est certainement grâce au travail de Pietro et Dario en 2020. Le drain dans la cour anglaise, le sump pump et toute les parois de la fondation ont fonctionné tel que prévu. Merci!

Why are customer references considered important in the concrete construction industry?

Why Customer References Matter in Concrete Construction

In the concrete construction world, a solid track record isn’t just nice to have—it’s essential. Clients want to know that their projects are in capable hands, and nothing reassures them more than hearing from others who’ve seen the process up close. Think of it like asking your neighbor which mechanic they trust; word-of-mouth is pure gold.

References provide proof that a company not only talks a good game but consistently delivers quality craftsmanship, sticks to timelines, and communicates clearly—all the traits you’d expect from a trusted pro. In fact, organizations like the American Concrete Institute and ASTM International emphasize the value of reputation and references when selecting contractors. It’s not just about pouring concrete; it’s about building confidence, one happy client at a time.

  • Prevention Guidance: Professionals may also offer recommendations and ongoing monitoring services to minimize the risk of future issues.

Whether your concerns are in the garage or basement, seeking specialized pyrite remediation ensures your property remains stable and your investment protected.

Enhancing Your Home with Durable Concrete Stairs, Balconies & Walkways

At Sous-Sols Experts, we understand that the strength and durability of concrete stairs, balconies, and walkways are crucial for the safety and aesthetic appeal of your property. Our expert team brings unparalleled expertise in constructing and repairing these essential elements to ensure they not only meet but exceed the industry standards.

Why Choose Concrete?

Durability and Longevity: Concrete is renowned for its long-lasting properties, standing up to harsh weather conditions without succumbing to the wear and tear that other materials can suffer. This makes it an ideal choice for the Canadian climate, ensuring your investment remains robust and maintenance-free for years to come.

Customization: While concrete is often celebrated for its durability, its versatility in design is frequently underestimated. Whether you are looking for sleek, modern aesthetics or a more traditional finish, concrete offers a range of textures, colors, and styles to match your home’s architecture and your personal taste.

Safety and Compliance: All our concrete installations are compliant with local building codes. Textured finishes can be applied to enhance safety, reducing slip hazards in wet or icy conditions, which is essential for stairs and walkways.

Our Services Include:

Concrete Stair Installation and Repair: From designing to installation, our comprehensive service ensures that each step is perfectly aligned and structurally sound. We also offer repair services to address any cracks, chips, or wear that might have occurred over time.

Balcony Design and Reconstruction: Balconies are not just an extension of your living space but a highlight of your home’s exterior. We ensure they are safely anchored and beautifully finished, offering both enclosed and open-air designs to suit your preferences.

Walkway Laying and Maintenance: A well-laid walkway not only enhances the curb appeal of your property but also improves accessibility. We specialize in creating smooth, even surfaces that integrate seamlessly with your landscaping design.
