Kristian came by to examine our foundation on 07/18/26. He was very informative and extremely professional. He gave us an incredible education on our foundation and steps going forward to monitor any issues. We found him to be extremely trustworthy and will definitely reach back out to him for future monitoring issues. Definitely a 5 star experience.

The work (driveway lifting) was done one day late from the original schedule because of some equipment issue. Roger from Ontario branch and crew were sent to perform the work but due to limited time they need to come back and rescheduled for another time the patching of the cracks. Alexis was sent to complete the job. Except for the scheduling issue, Think, overall they did a great job in leveling the driveway and patching the cracks.

I haven't had work done by Groundworks personally, but I can speak wholeheartedly to the character of Diego Blakely. I've known Diego for years, and he is one of the most trustworthy, hardworking, and dependable people I know. He brings genuine integrity to everything he does, and I have no doubt he brings that same professionalism and dedication to his work with homeowners. If you're looking for someone you can trust in your home, Diego is exactly that kind of person. Groundworks is lucky to have him on their team!

Tim Archer is a very trust worthy close friend of mine who I heard started at this company. With goals of purchasing a house myself in the future he has shared the importance of having a structurally sound foundation and groundworks is the place to make that happen
