This is the why behind Bill's hard work. Pictured are Bill and his wife, Jalyn, and their two precious children.

Bill Schlosser


Owner of Sunken Foundation Solutions

Bill Schlosser (blue shirt), owner of Sunken Foundation Solutions, is at every job site. When his crew is finished with the job, he makes sure the area is immaculate. Then he does a "walk through" with the homeowner giving them a final inspection of the completed job.


Bill Schlosser started his company back in 2018 under the name Schlosser Construction. Then, in December 2023, Bill decided to change his business name to Sunken Foundation Solutions. “Going forward, we will be leaning (no pun intended) more towards the fixing of setting and settling foundations,” says Bill.


So while the focus of the business is foundation repair, basement waterproofing, and crawl space repair, Bill says they are still available for other foundation/masonry repair projects such as retaining walls.


He recently added two additional services, and installing regress windows.
