What Stone Foundation Repair Entails

When it comes to keeping your home safe and structurally sound, few things are as important as a solid foundation. Over time, stone foundations can shift, crack, or deteriorate due to soil movement, moisture, or natural settling. Our team at FD Masonry specializes in stone foundation repair in St. Louis, delivering expert craftsmanship to homeowners in Afton, Belleville, Olivette, Ladue, Wildwood, Brentwood, and surrounding areas. We carefully assess your foundation’s condition to create a tailored repair plan that restores both strength and stability.


The repair process begins with identifying problem areas — such as cracks, gaps, or mortar deterioration — that allow water intrusion and weaken your home’s support system. We then remove compromised sections, replace damaged stone, and reapply high-quality mortar designed to bond securely and endure St. Louis’s seasonal weather changes. This process not only strengthens your foundation but also prevents recurring issues caused by improper drainage or settling soil.


Once repairs are complete, we apply waterproofing and sealant treatments to help protect your foundation for decades to come. The result is a safer, more secure home that resists moisture damage, improves property value, and stands firm against time. Whether you live in historic Belleville, charming Brentwood, or modern Wildwood, FD Masonry ensures your home’s foundation remains as dependable as the day it was built — with craftsmanship that lasts.
