Just because your home is newer doesn’t mean the foundation won’t develop cracks. This home was built in 2018 and there are 10 foundation cracks we are repairing this morning. It’s unfortunate to find these foundation issues in newer homes, but if you do, the pros at American Underground Specialist are here to diagnose and fix the problem.

Customer is selling home. He has multiple foundation cracks that are allowing water to enter basement. AUS is going to seal, inject, and supply new home owner with a WaterFree Guarantee. Please call (815)735-5586 if you are in need of foundation crack sealing.

Customer called with complaints of cold air infiltrating from crawl space to first floor. We -revised a free estimate for the insulating of floor joist, in order to keep hot air from escaping first level of home. We also found cracks in the foundation, as well as a good amount of moisture on crawl space floor.
