What Our Clients Say

There are no words to express how truly grateful I am to have had crew #1 lift and stabilize my entire home. Although they arrived Tuesday to just do my driveway side, by Wednesday morning they were willing to squeeze the entire house into their busy schedule. Spencer, Rob and Charles are incredible, and the work they did transformed my home. Their professionalism, workmanship, cleanliness and attention to detail exceeded my expectations and they genuinely cared about my satisfaction. It wasn’t just a job to them. Thank you so much!!! I am beyond happy and would highly recommend Groundhogs Property Services Ltd

I dealt mainly with Rob, and they were great. They replaced some posts under our house, were very open and honest with what I did need, and didn't need, didn't try to upsell me and thing I didn't need. Would highly recommend.

We had Groundhogs Ltd come and re-do a waterproofing system (blue-skin, weeping tile, & sump pit) at one of our properties. A previous contractor did a terrible job and we continued to have water issues. These guys know what they're doing and since they've left, we have had 0 water issues. Upon further inspection of the foundation on this job it was determined that the foundation was beginning to fail in one area. One of the Groundhogs crew recommended their PowerBrace product to us to fix the issue. This prevented any further movement of the foundation for years to come and it was much more affordable than replacing any parts of the structure. If you're looking for professional, efficient and honest people to come and waterproof or fix your foundation, call Groundhogs. They show up when they say they're going to, they determine the best solution and they fix it. 5 star company.
