Natalia Vassilieva

I can’t express how relieved I feel. Our foundation is solid, the house feels secure, and we no longer have to worry about future structural issues. It’s such a weight off our shoulders. I’m so grateful to FoundationGuard for their professionalism and expertise—this was a big project, but they made it as stress-free as possible. I would absolutely recommend them to anyone dealing with foundation problems!

Ermal Allmuca

The whole process went smoothly, and they kept us in the loop the entire time. The quality of their work speaks for itself - our home feels secure, and we couldn’t be happier. If you’re considering an underpinning project, we highly recommend them.

Matthew McLellan

I just wrapped up my basement renovation with FoundationGuard and I’m extremely pleased! They turned my old basement into a modern, inviting space that feels brand new. I've got to admit when I first engaged them I didn't quite see the vision (underpinning, finishings etc) of a fully finished basement but now I couldn't be happier. The entire basement renovation process was smooth – from design ideas to the final touches, they nailed it.
