    Care & Maintenance Tips for Longevity

    • Repair promptly – Replace any shifted pavers before small issues become big ones.

      Frequently Asked Questions

      Do I need a permit in Montreal?
      In Senneville, a permit is likely required for interlocking stone work, especially if it affects public sidewalks or drainage. The specific requirements depend on the nature and location of the work, so it’s best to contact the Municipality of Senneville to confirm. 
      How long does paving take in spring?
      A standard patio or driveway takes 3–5 days from excavation to cleanup—weather permitting.

      Thank you, Pietro, and your crew, for an absolutely impeccable job! You are truly a man of your word. Everything you explained during our consultation was exactly what you delivered! We have had a lot of work done on this old house over the years, and I can honestly say that I have never had such a smooth, worry-free experience. From the very beginning, everything was carefully thought out and well planned. There were no surprises, no cutting corners, and no unnecessary stress. You and your crew treated our home as if it were your own. The workmanship was professional, meticulous, and clean every single day. No matter what time you finished, you always made sure the house was left clean and in order. Thank you again, Pietro, for your honesty, attention to detail, professionalism, and outstanding workmanship. We couldn’t be happier with the results and would highly recommend you and your crew to anyone looking for quality work and a contractor they can truly trust. P.S. I almost forgot, thank you for accommodating us to keeping out washing machine during the work.

      I recenty hired Sous-Sols Experts to solve ongoing water flooding after heavy rains as the city infrastructure is inadequate. They installed a French drain system and a sump pump into my home, and the results have been excellent. Pietro and his team were professional, courteous and knowledgeable, and took the time to explain the causes of the drainage problems and the solutions they recommended. They worked efficiently, stayed on schedule, and kept the work area clean throughout the project and after. I was impressed by their attention to detail and the quality of their workmanship. The new French drain and sump pump system have given me peace of mind, knowing my basement is protected from future heavy rains. I highly recommend Sous-Sols Experts to anyone dealing with foundation drainage issues, basement water infiltration, or needing a reliable sump pump installation. Excellent service and outstanding results. Thank you Peter and your amazing team!!

      Highest praise and recommendation for this team. They gave me a new garage floor, new drains, including a long grate drain, outside my 'down driveway', new plumbing, and walked me through every step. They were efficient, effective, and big bonus, they were CLEAN! it was a 'cles en main' job, and they lived up to it. Extremely happy with the results.

      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 🙏
