“I’m very happy with the results and would definitely recommend them to anyone dealing with basement water issues.”

I had water coming into my basement and reached out to this company for help. They assessed the situation quickly and recommended waterproofing the foundation wall and installing a sump pump. The crew was professional, showed up on time, and kept everything clean throughout the process. Since the work was done, my basement has stayed completely dry—even through heavy rain. I’m very happy with the results and would definitely recommend them to anyone dealing with basement water issues.

“If you need a challenging retaining wall project done, Craig (Founder of WinStorm Projects) is your guy!”

“Craig and his team removed and replaced a failed concrete retaining wall along our property line with a new stone wall. This was a very challenging project due to tight access between properties and an awful neighbour to deal with. The headaches involved in the negotiations with the neighbour would have caused many contractors to walk away from the job, and I would not have blamed them one bit. Thanks to Craig being such a patient, honest and level-headed person, we were able to find solutions to problems every step of the way and get the job done. On top of that, Craig and his team were meticulous in their work, did a great job and did so for a reasonable price… If you need a challenging retaining wall project done, Craig is your guy!”

“[WinStorm Projects] went above and beyond to ensure the project was within the budget and my vision for my backyard.”

“After failed attempts to get quotes from other large local companies, I felt defeated that I would be able to find someone who would be able to replace my 64-foot retaining wall and patio, given the limited access to my backyard. And then, I met Craig and his team at WinStorm Projects… I was very impressed by the professionalism and quality of [Winstorm’s] work… I had many questions along the way, and Craig was quick to respond to them and offer suggestions and possible alternate options. He also went above and beyond to ensure the project was kept within the budget and my vision for my backyard.
It was a pleasure working with WinStorm Projects, and I would recommend them for any project, big or small.”
