Structural FAQs

What are the most common signs of foundation problems?

Look for diagonal cracks in walls, stuck windows/doors, and uneven floors. In Milwaukee, our expansive clay soil and freeze-thaw cycles exert tremendous pressure, causing settlement. Basement wall cracks, especially horizontal ones, indicate serious soil pressure. Don’t ignore gaps between walls and ceilings. Early detection is key to preventing more extensive, costly damage. If you see these signs, a professional inspection is crucial.

Is a cracked foundation wall a serious problem?

It depends. Hairline vertical cracks are often cosmetic. However, horizontal cracks, stair-step cracks in brick, or vertical cracks wider than 1/4 inch are red flags. These can signal structural failure from soil pressure or settlement. In Wisconsin, horizontal cracks often result from frost pressure against basement walls. Any crack that is leaking also requires immediate attention to prevent water damage and mold.

My floors are sloping. Is this normal settling or a sign of failure?

All homes settle, but significant sloping is rarely "normal." It often indicates differential settlement, where one part of the foundation sinks faster than another. This is common with unstable soil conditions. If you can feel a slope or see a ball roll consistently in one direction, it's time for an evaluation. We use precise tools to measure variance and determine if repair is needed.

What causes foundation problems in Southeastern Wisconsin?

Our primary enemy is expansive clay soil. It swells when wet and shrinks during droughts, causing constant movement. Combined with this is frost heave; frozen soil expands upward, lifting foundations, and then thaws, leaving voids. Poor drainage from clogged gutters or improper grading worsens both issues. Older homes may also have shallower footings not designed for modern soil pressures.

How do you repair a sinking or settling foundation?

We typically use steel piers driven deep to stable soil or bedrock. Push piers are hydraulically driven for heavy loads. Helical piers are screwed in for lighter loads or areas with limited access. This system permanently stabilizes the foundation, and hydraulic jacks can often carefully lift it back toward its original position. The best solution depends on your home’s specific soil and structural needs.

Will foundation repair fix my sticking doors and windows?

In most cases, yes. When a foundation settles, it twists the frame of your house, causing doors and windows to jam. By stabilizing the foundation and, where possible, lifting it back to a more level position, we correct the frame alignment. You should notice a significant improvement in their operation once the repair is complete, restoring the structural integrity of your home.


Waterproofing FAQs

What's the most effective way to stop water seepage?

For chronic water problems, an interior drain tile system is the most reliable solution. It captures water at the source—the footing—where hydrostatic pressure forces it in. A pipe embedded in gravel beneath the floor directs water to a sump pump for discharge. For active leaks, crack injection seals the pathway. In severe cases, exterior excavation and membrane installation may be recommended.

Is a sump pump necessary, and how is it maintained?

In Milwaukee, yes. A sump pump is your basement's first line of defense, collecting groundwater and ejecting it away from your home. To maintain it, test it quarterly by pouring water into the pit. Ensure the discharge line is clear and extends at least 10 feet from your foundation. Consider a battery backup system, as power often fails during severe storms when you need it most.

My basement smells musty. Does this mean I have mold?

A persistent musty odor almost always indicates mold or mildew growth, which requires moisture. Mold poses health risks and damages building materials. The source is often a chronic humidity problem or an unseen water leak, like through a crack or a poorly sealed cove joint. Professional waterproofing addresses the moisture source, and mold remediation may be needed to ensure a healthy environment.

What's the difference between crack injection and a full drainage system?

Crack injection is a targeted repair. We inject a specialized flexible epoxy or polyurethane resin into a crack to seal it permanently. An interior drainage system is a comprehensive solution for chronic water intrusion, managing water around the entire foundation perimeter. Crack injection fixes a specific leak; a drainage system manages bulk water flow to keep the entire basement dry.

How can I prepare my basement for spring thaw and heavy rains?

Ensure gutters are clean and downspouts extend at least 6 feet from your foundation. Grade the soil around your home so it slopes away. Test your sump pump and check for any new cracks in walls or floors. These simple steps help manage surface water, which is the leading cause of basement flooding during our heavy spring rains and rapid snowmelt.

Can you waterproof from the inside, or is excavating always necessary?

Excellent interior systems like drain tiles exist and are highly effective for most water issues. They are less disruptive and costly than exterior excavation. We recommend exterior waterproofing only in specific cases: when installing new drainage outside, for major structural repairs requiring excavation, or when internal access is impossible. For most homeowners, an interior system provides a permanent, robust solution.
