5 Major Signs of Foundation Failure

Written By Ted DrycePublished on 06/3/2012Updated on 06/2/2025

When you think about the most important part of your home, what comes to mind? Maybe it’s the roof or the walls. But, arguably more important than those is the foundation.

Your home’s foundation supports the entire structure (including the walls and roof). If foundation failure occurs, it can cause serious damage both inside and outside your home. Thankfully, the damage is easy to spot, which means you can stay on top of it if you know what to look for.

Foundation Problem Signs to Look For

Foundation issues can show up both inside and outside your home. With nearly three decades of foundation repair experience, we’ve seen the same foundation problem signs pop up time and time again at different homes. Here are the five most common ones to look for:

1. Foundation Settlement

When foundation failure starts, one of the first signs to show up is foundation settlement. Foundation settlement is when a foundation sinks into the ground, generally because of soil issues or extreme weather.

You might see certain sections of the foundation sinking into the ground while others don’t move at all. Industry experts call this “differential settlement”, because parts of the foundation are sinking at different rates.

At the end of the day, foundation settlement is the catalyst for pretty much all other forms of foundation damage. If you see settlement, expect to see even more issues on your property.

2. Drywall Cracks

Cracks in drywall are a clear sign of foundation damage. These cracks appear when the foundation settles unevenly, putting stress on the walls.

Since walls are not flexible, they crack when the foundation shifts. Drywall cracks often occur around the corners of doors and windows, as these are the weakest sections of the walls.

3. Uneven Floors

Another common and serious sign of foundation failure is an uneven floor. Since your floors are directly supported by the foundation, any movement of the foundation will also cause the floors to move.

If the foundation settles unevenly, it will floors may tilt, slant, or bulge. They may even separate from the floorboards.

4. Sticking Windows & Doors

When your foundation shifts, it can affect the frames of doors and windows, causing them to become misaligned. This leads to doors dragging on the floor and windows opening with difficulty and resistance. In severe cases, doors and windows can even make them unable to open or close.

5. Cracking Bricks

When the foundation under a house moves or settles unevenly, it puts pressure on the brick walls above it. This pressure and movement causes the bricks to crack.

The cracks might look like stair-step patterns or straight lines running through the mortar (the material between the bricks). These cracks indicate that the foundation is shifting and affecting the structure of the entire building.

How to Fix & Prevent Foundation Failure

We know that dealing with foundation failure is stressful, but with professional repair methods, fixing damage is easy, and preventing it from coming back is possible. Here are the best ways to fix foundation issues:

Push Piers: Workers drive these deep into the ground to support and lift sinking foundations.
Helical Piers: Installers twist these into the ground, making them great for lighter buildings or soft soil.
Slab Piers: Specialists place these directly underneath concrete slabs to lift and support them.
Wall Anchors: These pull leaning or bowing walls back into place. Technicians anchor the walls to stable, hard soil away from your house.
Steel I-Beams: Installers place these against the interior side of basement walls to provide extra support and prevent the walls from moving inward.
Carbon Fiber Reinforcement: Contractors bond these strong, durable strips to the foundation wall to stop bowing and cracks.
Crawl Space Support Jacks: Technicians position these jacks to lift and support sagging crawl space beams, thereby restoring the structure above.

Each method actively addresses specific foundation problems, ensuring stability and preventing further damage to your home. AquaGuard Foundation Solutions can install any of these repair methods at your home, so consider working with us to keep your foundation safe.
