Foundation & Basement Problems in Marshalltown
Homes across Marshalltown are built on soils that move with the seasons. During wet periods, the ground around your foundation swells and pushes against basement walls. In dry spells, the soil contracts and shifts away—creating gaps beneath footings and leaving walls unsupported.
This movement leads to cracking, bowing, and water intrusion over time. Many Marshalltown homeowners first notice small foundation cracks caused by soil shifting beneath the home. Moisture then seeps into these cracks, widening them and accelerating structural damage. Older basements without modern waterproofing are especially vulnerable. Water stains, musty odors, and mold growth are common in homes with poor drainage. Outside, concrete steps, driveways, and patios often sink or crack due to freeze-thaw cycles and soil erosion. Addressing these problems early helps prevent higher repair costs and protects your home’s value.

Signs Your Home May Need Foundation or Basement Repair
In Marshalltown, foundation and basement issues often show themselves through small but persistent changes. You might notice cracks in brick veneers or concrete walls, or find damp spots in your basement after a rain. Musty odors—both inside and outside your home—can indicate hidden mold or moisture problems.
Chimneys may begin to lean, concrete steps can deteriorate, and interior walls may start to curve inward or outward. Floors that once felt solid may develop subtle slopes or uneven spots, and doors or windows may stick as the foundation shifts beneath them. If you’re seeing any of these warning signs, don’t wait. Contact Anchored Walls for a professional inspection. We’ll evaluate your foundation and provide a clear plan to restore your home’s stability.

After getting bids and talking with a few different contractors regarding what we needed for waterproofing our basement, I was feeling pretty overwhelmed, anxious and stressed out. Elliott was a breath of fresh air. He's a very nice, respectful guy. He is very knowledgeable and was easy to talk to. After speaking with him, I felt more at ease and less anxious about the whole process. Because of Elliott, we plan to move forward with Anchored Walls for our basement waterproofing.

Frequently Asked Questions
Why is there mold in my crawl space?
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.
How much does foundation repair cost?
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.
Are foundation cracks serious or just cosmetic?
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 I don't repair my foundation, what could happen?
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.
What causes foundation problems in the first place?
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.
