According to This Old House, basement waterproofing projects typically range between $2,500 and $8,000, depending on the size of your home, the extent of the problem, and the type of solution needed. Costs can vary based on whether the work involves interior drainage, sump pump installation, or exterior membrane systems, but many homeowners are pleasantly surprised to find that effective waterproofing is more affordable than expected.
Absolutely. Finishing your basement without a waterproofing system can trap moisture inside, leading to mold, rot, and ruined finishes. A properly sealed basement ensures long-term comfort and protects your investment before drywall or flooring goes in.
It can be hard to tell: interior wet spots may come from leaks, condensation, or indoor humidity, while exterior issues stem from poor drainage or groundwater. A professional inspection can determine the source, then match it to the right solution, whether that’s interior sealing or exterior drainage.
Yes, especially if it’s wider than a hairline, actively leaking, or paired with moisture. Cracks can let water in and weaken your foundation over time. Interior crack injection or exterior sealing can fix leaks; if it’s structural, you’ll want to explore foundation repair options to protect your home.
A persistent musty odor often means moisture is present, even if you don’t see leaks. That dampness creates ideal conditions for mold and mildew. As air moves through your home, the smell and potentially harmful spores can drift upstairs. Addressing the moisture source is the only way to eliminate it for good.
Water intrusion during rain is usually due to hydrostatic pressure—rainwater accumulating in the soil pushes through foundation cracks, joints, or window wells. It might seem harmless at first, but repeated leaks signal worsening conditions. A drainage system or professional waterproofing can stop this for good.
If you don’t have a basement waterproofing system installed at your home, the moisture that collects will eventually begin to cause your basement walls and floors to deteriorate. Also, excessive basement moisture can lead to the growth of mold and mildew, which is unsafe for your family to be breath
Basement moisture is usually caused from cracks along the foundation or an improper drainage system. Foundation cracks act as an entry way for water. Water always seeks the path of least resistance, and this means that water is very likely to enter through these foundation cracks.
If left untreated, basement moisture can begin causing damage to both your basement walls and your basement floor.
Foam stands out for concrete leveling because it’s clean, fast, and durable. Unlike legacy methods that require large holes or create messy slurry, foam uses small injection points, expands to fill voids evenly, and becomes waterproof in minutes. It's also lightweight—meaning it won’t collapse the repaired area—and cures fast enough for immediate use. That’s why professionals prefer foam for fast, reliable leveling with minimal disruption.
For most homeowners, yes. Leveling is typically faster, less invasive, and significantly more affordable than tearing out and repouring concrete. It also avoids the mess, downtime, and disruption that come with full replacement.
Most settling is caused by changes in the soil beneath the slab. Water erosion, poor compaction during construction, freeze-thaw cycles, or underground voids can all create pockets where the concrete loses support. Over time, gravity takes over and the slab sinks or shifts.
Polyurethane is tough. It’s solid, water-resistant, and won't be damaged by chemicals, bugs, or rodents. As long as the surrounding soil holds up, the repair will too—indefinitely.
Yes! The material is non-toxic and environmentally safe. Once it cures, it's inert (like a sealed balloon) and doesn’t leach into the ground.
Costs depend on how much material is needed. It’s usually half the cost (or less) of full concrete replacement. We use our own advanced estimating software to provide accurate quotes.
That depends on the method. Polyurethane foam cures within minutes, allowing use the same day—often within an hour. Slurry-based lifting methods may require a longer cure time, but are still far quicker than replacing the slab.
Most concrete leveling jobs can be completed in just a few hours. The size of the slab, the extent of the sinking, and the repair method all affect timing, but it’s typically much faster and less disruptive than full concrete replacement.
Concrete leveling restores sunken or uneven slabs by injecting material beneath the surface to raise it back into place. Small holes are drilled into the concrete, and a lifting compound, such as foam or slurry, is pumped underneath. The slab is gently raised, leveled, and the holes are patched cleanly once the work is complete.
According to HomeAdvisor, crawl space repairs typically range from $4,500 to $8,000, with most homeowners spending around $6,000. Costs depend on the size of your space, the extent of moisture or structural damage, and whether additional systems, like drainage or encapsulation, are needed. We’ll walk you through every option and provide a clear, customized estimate before any work begins.
A standard crawl space encapsulation can often be completed within 2–4 days, depending on site conditions. If structural repairs or drainage systems are required, the project may extend longer. We always walk you through the timeline before work begins, so you know exactly what to expect.
Yes, especially if humidity regularly exceeds 65%. A dehumidifier controls moisture that vapor barriers and drainage systems miss. Maintaining proper humidity prevents mold, rot, and musty smells, and helps protect HVAC ductwork and insulation in the crawl space.
Encapsulation typically involves installing a durable vapor barrier across the floor and walls, sealing off vents, and sometimes adding a dehumidifier or perimeter drain. The goal is to create a dry, insulated envelope that protects your foundation and improves comfort and efficiency.
Crawl space waterproofing stops ground moisture and pipe condensation from damaging your home’s structure and air quality. Without it, damp air rises—potentially feeding mold and mildew throughout your house. A well-sealed crawl space also helps reduce energy loss and keeps pests from nesting under your floors.
The crawl space has an integral role towards a home's overall indoor air quality. Many homeowners don't think twice about their crawl space, unless it starts leaking or growing mold. Research shows that nearly 50% of the air in your home has circulated up from your crawl space. This means that if you have a moldy crawl space, you're breathing in air containing mold spores. Mold can cause allergies, fevers, headaches, flu-like symptoms and a variety of other health issues. Anchored Walls' foundation repair services are based on each individual job, depending on the severity. To receive an estimate, please call us at 888-662-3363.
Look for signs like sagging subflooring, musty smells, mold growth, high humidity, standing water, or visible rot on floor joists and beams. These often show up first in closets or laundry rooms above the crawl space. All of these issues point to possible structural or moisture problems below.
Mold is a result of excessive moisture in the crawl space of your home. It’s very important that you take care of a moldy crawl space problem as soon as you notice that something is wrong. If left untreated, mold can cause a number of problems for the structural integrity of your home, as well as your family’s health. If you don’t repair your foundation, water will eventually seep in. This causes an assortment of additional problems for the structural integrity of your home.
Crawl space moisture comes from water seepage, improper yard drainage systems, soil settlement and condensation. Regardless of whether your crawl space is dirt, concrete, vented or unconditioned, these lower areas underneath the home tend to endure the most damage due to the many changes in weather conditions, high temperatures and humidity levels. Humidity and moisture easily travel through your crawl space and can begin to infiltrate the structure of your home.
Damp or wet crawl spaces are perfect homes for insects, rodents and other critters. This area underneath your home can be extremely unhealthy, destructive and dangerous. Your wet crawl space can also act as a breeding ground for mold and mildew growth. Mold spreads easily throughout your home when it begins in your crawl space. Mold, as well as wood rot, can negatively affect your home’s indoor air quality. That’s why it’s important to take care of crawl space moisture problems as soon as you notice them.
To meet code in Iowa, an egress window must:
If your window is below ground level:
Yes! Adding an egress window can legally convert a basement into livable space, increasing your home’s usable square footage and boosting property value. Natural light is a bonus, too.
It depends on your preferences and layout. Common choices include casement, sliding, single hung, and double hung windows. Our team can help you choose the best option for function and style.
Most installations are completed in just a few business days. We aim to get the job done quickly and with minimal disruption to your home.
Costs vary depending on your project, but we provide a free consultation to give you a detailed estimate. Factors that affect price include:
Yes. Unrepaired foundation problems can reduce your home’s value and may raise red flags during a sale or appraisal. On the other hand, professionally completed foundation repairs help preserve your home’s structure and restore buyer confidence.
Many foundation repairs—like crack injections or wall stabilization—can be completed in a single day. Larger structural work may take a few days, depending on site conditions and the type of system being installed. Either way, we’ll keep the process efficient, clean, and fully explained from start to finish.
Not necessarily. Bowing walls often respond well to stabilizing systems like wall anchors or carbon-fiber strips. In severe cases, structural underpinning may be needed, but many bowing issues can be corrected without full wall replacement.
Most foundation cracks can be repaired, especially if caught early. We use methods like injection or stabilization to stop water and movement. Full foundation replacement is rare and usually only needed when damage is severe and widespread.
Some of the most common warning signs include cracks in your walls or floors, doors or windows that stick, uneven flooring, or gaps forming around baseboards and trim. These may seem minor at first, but they’re often caused by foundation movement and the longer they go untreated, the more costly the repairs can become.
According to This Old House, most foundation repair projects range from $2,000 to $10,000, depending on the size of the home, the type of foundation, and the severity of the damage. Small crack repairs may fall near the lower end, while structural issues that require stabilization or piering will be higher. Every home is different, but a professional inspection can help identify the most cost-effective path forward.
Some small, vertical cracks may be normal settling, but if a crack is widening, leaking water, or forming a stair-step or horizontal pattern, it could signal a structural issue. It’s always best to have cracks professionally evaluated to determine whether repair is needed.
If you don’t repair your foundation, water will eventually seep in. This causes an assortment of additional problems for the structural integrity of your home.
Most foundation issues are caused by changes in the soil around your home. Drought, heavy rain, poor drainage, and construction on improperly compacted soil can all lead to movement under your foundation. Over time, this movement creates stress on the structure and leads to cracks, shifting, or settling.
