  • Nick Lagasse

    Jason and his team are exceptional communicators and educators. We replaced a septic system as part of a larger renovation to meet code. Jason had the patience to answer our many questions. When on site, the work ethic and hustle are apparent. Thanks for everything, Jason!24

  • Paul Kalata

    Jason and his team went above and beyond to ensure our family was satisfied with the new septic system installed on our Lake Joseph island property. The team was on time, in constant communication and extremely hard working. Thank you!!!

  • Melissa Douglas

    We called Jason last minute for an emergency septic replacement, a 10,000-litre system. He was able to work with the building department and get the design and permit approved in two days. He had the new system installed and fully functional in 4 days! Super great team of professionals.

  • Cameron McAlpine

    We needed a septic solution to solve a complicated problem, and Jason was able to design a system that works perfectly. He is very responsive and was able to complete the job quickly at a competitive price. I also appreciate that he’s provided some good advice after the installation. Couldn’t be happier with the results.

  • Jeffrey Costa

    Jason came out and dug my foundation for my house and put my new septic system in. He was in and out within 3 days. Very pleased with his attention to detail and the long hours he put in.

  • Dennis Maceyovski

    Our build is finally happening! Thanks to the team, the sewer connection was located, and the water and sewer connections were made and brought to the basement area. The basement hole was dug masterfully along with the electrical trench. Great team! Thank-you!

    We had a huge job that needed to be taken care of, VERY old septic removed and new system installed with some property boundaries and wet ground issues. Jason and his team proceeded to remove and install regardless of what the problem was, they truly did a beautiful job. Seeded the area where work was done and even fixed up our driveway after the machines were working in that area.

  • Karol Porcaro

    Jason and his team did excellent work for our full septic redo and leeching bed. They did a great job with the clean up. Would 100% recommend them. Thank you Jason and Team.

  • Patty & Gord Craig

    Jason was great, helped me with the permit process. He worked with the inspector and got the job done fast. His crew was polite and helpful. We would highly recommend him.

  • Erin Welsh

    Working with Jason, were happy with the process from the beginning. He was easy to work with, showed up on time, and got the job done right. He communicated throughout the install and made sure everything was cleaned up after. Would definitely recommend them to anyone needing a septic system on a water access property especially.

  • Trenanthia Cottage

    Jason was so pleasant and professional through out the entire process and was able to complete a HUGE amount of work within our tight deadline. He was also very communicative and clear when we faced some issues and explained them in a way that was easy to understand so that we could make informed decisions. Highly recommend Jason & his team!

  • Joanne R.

    I reached out to Jason to inquire about a septic pump issue that we were having. He was very responsive and helpful in trouble shooting the situation. His expertise, combined with his flexibility to accomodate the obstacles that mother nature set in our path was a welcome relief. I would highly recommend Jason.

  • Sarah Veenstra

    My partner and I recently moved into the area starting a home building company. Jason and his team were knowledgeable and helpful throughout the entire process. From excavating, to septic install, and backfilling, they made it a seamless experience. Even with our tight building lot they knew exactly what septic would do the job we needed. Jason worked efficiently and understanding our tight scheduling. We look forward to working with them on many more builds in the future.
