"Leonard and his crew did a magnificent job rebuilding a set of stone steps topped with concrete slab and repairing a field stone foundation wall that water had damaged. He and his crew are both skilled artisans and artists. He is polite, honest, and hard-working, and his services, quite reasonably priced, are worth every penny spent. Hire this man."

"Outstanding! John took our vision and brought it to life in a way that went beyond anything we could have imagined. What could have been a simple repair turned into a complete transformation. The stonework they created not only improved the look of our home but made it stand out in the neighborhood. People keep stopping in front of the house to admire it. The quality, craftsmanship, and attention to detail are second to none."

Foundation Repair questions, answered by experts

Foundation repair can affect home value positively or negatively. If you address the underlying issue and hire a foundation repair contractor to complete the work—especially one that includes a warranty for the work—then your repair will likely increase your home’s value. If you fail to pull proper permits and cannot prove that a licensed expert completed the work, there’s a chance buyers will view your home in a negative light and end up offering less for your property.

While it can be difficult to identify a bad foundation at first glance, look for large horizontal cracks, discoloration, bulging basement walls, or signs of water damage. You may also see large gaps between the home and the foundation on the outside or signs of pooling water from a recent storm.

Whether your homeowners insurance covers slab leak repairs depends on your specific policy and the cause of the leak. Many policies cover slab leaks resulting from a covered peril, such as a natural disaster, a falling tree, or pipes freezing and bursting within the slab. However, damage caused by invading tree roots, corrosion, or leaks from appliances may not be covered by a standard policy. It's a good idea to also check your home warranty plan for potential coverage if an appliance is the source. Contact your insurance provider for a full explanation of what your policy covers.

Violating building codes can lead to a number of consequences, including fines, citations, and even being required to demolish the structure and start over. If your house isn’t compliant with code requirements, you can also run into trouble when it comes time to get homeowners insurance or sell your house. Following all applicable building codes will avert costly consequences.

Yes, a house can collapse from severe foundation problems if they are left unchecked. However, this is a rare occurrence that typically takes many years to develop, and a partial collapse is more likely than a full one. Homes on hillsides or in areas with frequent washouts are at a higher risk. Barring a natural disaster or other extreme circumstances, clear signs of major issues will be apparent long before a collapse is imminent. It is crucial to conduct routine foundation inspections and address any problem, no matter how minor it seems, as soon as possible to avoid threatening the structural integrity of your home.
