Expert Foundation Repair St. Louis Homeowners Trust
For all of your Basement Waterproofing and Foundation Repair in St. Louis …

Affordable Basement Waterproofing and Foundation Repair in St. Louis
We started this business after seeing too many neighbors in South County and across St. Louis get stuck with overpriced, one-size-fits-all solutions for their foundation problems. My own home near Grant’s Farm had a crawl space that flooded every spring—until I figured out how to fix it myself. That experience shaped how we approach every job at Fred’s Foundation Repair and Waterproofing: with practical, affordable solutions designed for your property, your soil, and your budget.
If you live anywhere from Oakville to Affton, Mehlville to Lemay, you’ve likely seen the warning signs—sticking doors, sloping floors, water seeping into the basement after a heavy Midwest storm. Around here, our clay-heavy soil expands and contracts through the seasons, creating the perfect conditions for structural issues. That’s why we focus so heavily on foundation repair St. Louis homeowners can truly rely on—solutions that are honest, effective, and tailored specifically to our local soil and terrain.
At the end of the day, we’re not just fixing cracks or installing sump pumps—we’re helping people feel secure in their homes again. As a small, family-run company, every project is personal. When you hire us, you’re not just another job on the calendar—you’re a neighbor, and we treat your home like our own.

At Fred’s Foundation Repair & Waterproofing, we provide cost-effective foundation repair and basement waterproofing in St. Louis by keeping things simple and honest.

Because we rely on word-of-mouth referrals instead of expensive advertising, we’re able to offer practical, affordable solutions that focus on fixing the actual problem — not selling homeowners on unnecessary systems or upgrades. Our goal is to recommend only the repairs your home truly needs, whether that’s foundation crack repair, waterproofing, or structural stabilization.
Homeowners throughout St. Louis and St. Louis County choose Fred’s because they want professional foundation repair at a fair, transparent price, delivered by a local team that stands behind its work.

What Is Foundation Repair?
Foundation repair is the process of stabilizing and correcting structural problems caused by soil movement, water intrusion, settling, or age. In St. Louis, these issues are common due to expansive clay soils, freeze-thaw cycles, and drainage challenges around older homes.
Solutions may include crack repair, wall stabilization, pier installation, or drainage improvements, depending on the severity of the issue. The goal is to restore structural integrity, prevent further damage, and protect your home’s long-term value.
At Fred’s Foundation Repair & Waterproofing, we provide problem-specific, cost-effective foundation repair solutions, helping St. Louis homeowners fix what’s needed — without unnecessary systems or added expense.

When it comes to foundation repair in St. Louis, water is usually the first warning sign. Our shifting clay soil and nonstop weather swings create pressure around your foundation, forcing moisture through cracks, gaps, and weak points. That’s why we combine proven waterproofing systems with structural repair methods that actually address the root of the problem rather than just treating the symptoms.
We begin every job by figuring out how water is interacting with your foundation. In neighborhoods like Lemay and Oakville, that often means installing interior drain tile systems that quietly collect and redirect groundwater before it can flood your floors or worsen foundation damage. For exterior protection, we apply waterproofing membranes, drainage boards, and sealants that keep water away from foundation walls and help prevent settlement and cracking.
If your home needs it, we install or replace sump pumps to keep basements and crawl spaces dry. These systems are critical in flood-prone parts of South County and anywhere near the River Des Peres. To relieve surface pressure around your foundation, we also design French drain systems that move water safely away from your home’s perimeter.
When water has already made its way inside, we offer basement waterproofing solutions that stop active leaks and prevent mold. Our basement crack repair process uses industrial-grade injection systems to seal problem areas permanently, protecting both your living space and the structural integrity of your foundation.
Homes with crawl spaces benefit from our full encapsulation service, which creates a sealed, dry environment using vapor barriers, drainage improvements, and insulation. This not only protects your foundation, but also improves air quality and energy efficiency. We also install foundation waterproofing coatings on both existing homes and new construction for long-term moisture defense.
If you’re unsure where the problem starts, our basement leak detection service pinpoints the exact source of moisture and guides us toward the correct fix. For added durability, we apply basement wall sealing products that form a long-lasting barrier against water intrusion and hydrostatic pressure.
Every waterproofing system we install is built with St. Louis foundation repair in mind—local soil, local weather, local challenges. We live here too, and we know exactly what your home is up against.
Concrete Contractor Services in South St. Louis County
When it comes to concrete work, most folks think of driveways and sidewalks—but for us, it’s all about what’s beneath your home. As a concrete contractor serving St. Louis and the South County area, we focus on stabilizing, leveling, and reinforcing the structures that support your home or business. This isn’t cosmetic work—it’s structural. It’s what keeps your doors from sticking and your walls from cracking when the ground shifts under your feet.
We offer concrete foundation repair for homes experiencing settlement or sinking, using proven methods that stabilize and secure the base of your property. If you’ve spotted long horizontal cracks or your basement walls are starting to bow, our cracked foundation repair and concrete basement wall repair services address the damage before it spreads.
In areas like Mehlville and Concord, where homes are often built on clay-rich soils, uneven settling is common. Our concrete slab leveling corrects tilted or sunken slabs, restoring safety and preventing trip hazards. For deeper support, we offer concrete pier installation and concrete footing installation—solutions that go beneath the surface to keep your structure upright and stable.
We also provide concrete underpinning services for properties that need extra reinforcement due to age, soil movement, or remodeling. And if your home is supported by block walls, our block foundation repair services are designed specifically to strengthen and seal those systems against further deterioration. Finally, when deeper soil support is needed, we rely on helical pier installation and push pier installation to give your foundation the long-term stability it needs.
Our approach isn’t one-size-fits-all. We take the time to assess each structure individually and apply the right solution for the soil, age, and construction style of your home.

FAQs at Fred's Foundation Repair and Waterproofing
In St. Louis—where historic brick homes meet newer builds—it’s not uncommon to find foundation issues during a home inspection. But knowing when to walk away from a home with foundation problems comes down to a few key factors.
If the cost of foundation repair in St. Louis exceeds your budget, even after negotiating with the seller, it might not be worth the risk. Extensive structural damage, long timelines for repair, or uncertainty around future maintenance could leave you in temporary housing longer than planned.
South County soil conditions and freeze-thaw cycles are notorious for causing shifting and settlement. If an inspection reveals signs of serious issues—like bowing basement walls, large horizontal cracks, or water intrusion—you’re likely facing recurring maintenance costs.
In short, walk away if the repair costs are high, the timeline interferes with your plans, or the scope of work leaves you uneasy. St. Louis has no shortage of solid homes, and avoiding a risky purchase can save you stress down the line.
Still unsure? Schedule a free foundation estimate with Fred’s Foundation Repair and Waterproofing to make a confident, informed decision.
In St. Louis’s active housing market—especially in neighborhoods like Affton, Oakville, and Mehlville—deciding whether to repair foundation issues before listing your home depends on several key factors.
Fixing foundation problems before selling can boost your home’s value and reduce negotiation roadblocks. Buyers often feel more confident making offers when they know the home is structurally sound. If you’re targeting top-dollar offers or aiming for a quick sale, investing in foundation repair in St. Louis might be a smart move.
That said, repairs aren’t always necessary. If the foundation issues are minor or if the local market is hot, you may still attract buyers willing to take on the work themselves—especially if you’re transparent. Offering a detailed inspection report or a quote from a trusted contractor like Fred’s Foundation Repair helps set expectations and builds trust.
In South County and other parts of the metro area where clay-heavy soil leads to shifting foundations, it’s common for homes to have some degree of movement. Buyers expect this—what matters is how you present it.
Ultimately, consider the repair costs, the severity of the issues, and what local buyers are looking for. If in doubt, schedule a free foundation estimate and weigh your options with expert insight.
In St. Louis—where homes in areas like Lemay, Sunset Hills, and Concord often experience shifting soil and seasonal moisture—foundation cracks are common. But does your insurance policy cover them? The answer: it depends.
Most homeowners insurance policies do not cover foundation cracks caused by natural settling, age, or general wear and tear. These are considered maintenance issues and fall outside standard coverage. However, if the crack results from a covered peril—such as a burst pipe, fire, or vehicle impact—then repairs might be reimbursed under your dwelling coverage.
In St. Louis, where clay-rich soil and fluctuating weather can cause foundations to shift or crack, many residents are surprised to learn that earthquake, flood, and sewer backup damage usually require separate endorsements or riders. If you’re concerned about those risks, it’s worth calling your insurer to ask whether you’re protected.
Understanding your policy is key. Review your coverage details carefully and consider supplemental insurance if you’re in a high-risk area. It’s also smart to get a professional opinion—Fred’s Foundation Repair offers free assessments to help you understand the cause of cracks and the potential costs involved.
Living in St. Louis—especially in areas like Affton, Mehlville, or Oakville—means dealing with seasonal moisture swings and shifting soils. These conditions can quietly damage your foundation over time. So how can you tell if your home is affected?
Here are key warning signs:
Cracks in Exterior Walls: Wide or stair-step cracks in brick or block walls are often signs of settling.
Interior Cracks Near Ceilings or Floors: Jagged or diagonal cracks along drywall, especially near windows and doors, are red flags.
Sticky Doors & Windows: If doors or windows suddenly start jamming or not closing right, the frames may be warped from foundation movement.
Bouncy or Sloping Floors: This often points to pier and beam issues, sagging joists, or shifting support beams.
Gaps Behind Cabinets & Counters: When built-ins start pulling away from the wall, the structure may be shifting.
Musty Smells in Basement or Crawl Space: Damp, mildew-scented air can signal water intrusion through cracks.
Sinking Soil Around the Foundation: This can cause further instability and points to drainage or erosion issues.
If you notice one or more of these signs, it’s time for a professional inspection. At Fred’s Foundation Repair, we offer free estimates throughout St. Louis County. Catching issues early can save you thousands down the road.
Crawl spaces are common in many St. Louis homes, especially in older neighborhoods like Lemay and parts of South City. While they provide easy access to plumbing and wiring, they also come with some serious drawbacks.
First, crawl spaces are prone to moisture. St. Louis’s humid summers and clay-heavy soil make standing water and condensation a regular issue. This damp environment can lead to mold, mildew, and even structural wood rot, especially if the crawl space has a dirt floor or poor drainage.
Pest problems are another concern. Rodents, termites, and insects often nest in these spaces when conditions are damp and dark. Poor insulation and air circulation can also affect your home’s energy efficiency—leading to drafts in winter and higher cooling bills in summer.
Maintenance is another challenge. Because crawl spaces are tight and difficult to access, problems like leaks, sagging insulation, or deteriorating joists often go unnoticed until serious damage occurs.
Solutions like crawl space encapsulation, vapor barriers, sump pumps, and drainage systems can help. But in areas with persistent water problems, slab foundations may be a better long-term option.
If your home has a crawl space and you’re seeing signs of moisture or poor air quality, Fred’s Foundation Repair offers inspections and affordable crawl space solutions across St. Louis and South County.
