Foundation Repair
Is your foundation cracking, settling, or bowing? A-Proseal has fixed thousands of Chicago-area foundations since 2000. We use proven methods like helical piers, wall anchors, and carbon fiber straps to make your home safe and stable again.
Chicago's Clay Soil Is Hard on Foundations
Chicago sits on thick layers of heavy clay. When this clay gets wet, it swells and pushes against your foundation walls with great force. When it dries out in summer, it shrinks and pulls away. This push-and-pull cycle happens every single year. Over time, it causes cracks, bowing walls, and uneven settling that puts your whole home at risk.
Winter makes things even tougher. Chicago frost can reach four feet deep into the ground. Frozen soil expands and shoves against your foundation from every side. When spring comes, the quick thaw leaves loose soil and gaps where your footings can shift and drop. Older Chicago homes built on shallow footings are especially vulnerable to this kind of damage.
Many homes across the city are 50 to 100 years old. Their foundations were not built to handle this much stress over so many decades. If you notice new cracks in your basement walls, doors that stick, or floors that slope, those are signs that the soil around your home is winning the battle against your foundation.
A-Proseal has been stopping foundation damage across the Chicago area since 2000. Our team uses engineered solutions like helical piers, wall anchors, I-beam bracing, and carbon fiber reinforcement. Every repair comes with a written warranty, and we offer free same-day inspections so you can get answers fast.

What You Get With Our Foundation Repair
Helical Pier Systems
Steel piers are screwed deep into stable soil far below your foundation. They lift and support your home from underneath, stopping settling in its tracks. This is the best fix for sinking or uneven foundations sitting on Chicago's shifting clay.
Wall Anchor Systems
Steel anchors connect your basement wall to stable soil out in your yard. They hold bowing walls in place and can slowly straighten them back over time. This method works great for walls that have moved inward from heavy soil pressure.
I-Beam Wall Bracing
Heavy steel I-beams are placed against your basement wall from floor to ceiling. They stop inward movement and keep your wall from bowing any further. I-beams are a strong, proven solution for both block walls and poured concrete walls.
Carbon Fiber Reinforcement
High-strength carbon fiber straps are bonded directly to your basement wall. They add serious holding power without taking up any space. Carbon fiber is perfect for walls with minor bowing or early-stage cracking before the damage gets worse.
Written Lifetime Warranty
Every foundation repair we do comes with a written warranty. If anything we fixed ever has a problem again, we come back and make it right. You can also transfer the warranty if you sell your home, which adds real value for buyers.
Thorough Site Cleanup
When the job is done, we clean up everything. We haul away all debris, fill in any holes we dug, and leave your property looking neat. You will not have to lift a finger after we finish the repair work on your home.

Foundation repair is a big deal. You need a company that truly knows Chicago homes, uses the right methods, and stands behind their work. That is exactly what our team delivers on every single project.
Foundation Repair Questions Chicago Homeowners Ask
Most foundation repairs take one to three days. Smaller jobs like carbon fiber strap installation can sometimes be done in a single day. Larger projects that need multiple helical piers or wall anchors may take up to five days. Our team will give you a clear timeline before we start so you know exactly what to plan for.
Foundation repair stops the movement that caused the cracks in the first place. Once the foundation is stabilized, many cracks will close up on their own over time. For larger cracks, our team can fill and seal them as part of the repair. After the foundation is properly supported, new cracks should not form.
No. You can stay in your home while we work. Most of the repair happens outside or in the basement. There is some noise and vibration during pier installation, but nothing that would make the home unsafe to live in. Our crew keeps the work area clean and contained so your daily life is not disrupted.
Chicago's heavy clay soil is the main reason. Clay swells when it gets wet and shrinks when it dries, creating a constant push-pull cycle against your foundation. Frost heave in winter adds even more stress. Poor drainage around the home, tree roots pulling moisture from the soil, and the natural aging of older foundations also play a role. These forces work together over the years to cause settling and cracking.
Yes. A repaired foundation removes a major red flag for home buyers and inspectors. The written warranty we provide is transferable to the new owner, which gives them real confidence. Homes with documented foundation repairs and transferable warranties often sell faster than homes with unresolved foundation problems.
Small hairline cracks are normal in most homes and are usually not a concern. But if you see cracks wider than a quarter inch, diagonal cracks running from corners of windows or doors, walls bowing inward, or floors that slope noticeably, those are signs of a bigger problem. Sticking doors and windows are another common warning. The safest move is to call us for a free inspection. We will tell you honestly whether you need repairs or not.
