If every heavy rain has you heading downstairs to check the basement, it is time to figure out where that water is coming from. At Anchored Walls, our basement waterproofing solutions address the problem at the source, protecting your home and your peace of mind.
Signs You Need Basement Waterproofing
You can minimize basement water damage by spotting warning signs early and addressing them before they spread. Perhaps, one of the most severe risks of not fixing a wet basement, is the proliferation of mold and mildew. More importantly, however, is the fact that mold and mildew growth in your wet basement can lead to health problems for you and your loved ones. These mold spores are released into the air you breathe and can cause flu-like symptoms, headaches, respiratory problems, fevers, and more. If left untreated in the basement, the mold can actually start growing in other parts of your home.Keep an eye out for:

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.

Anchored Walls techs, Zach and Kyle, came ready to work!!! They added 9 anchors to 2 of my basement walls to stabilize them. Those 2 men worked hard! I have attached 2 pictures, the first shows shovels over the holes so no one would fall in, and the finished yard. You cannot tell where the holes had been. Both men also added waterproofing to my basement floor. If Zach and Kyle are an example of what to expect when you hire Anchored Walls, then the company gets 5 stars from me. Great work Zach and Kyle !!! * * * * *

I bought an old townhouse and found leakage into the basement under a window well. I had Anchored Walls come out to inspect. Roger diagnosed the problem as 30-yr buildup of silt preventing water from draining down to the tile. He recommended excavation and rebuild with clean pea gravel fill. A 2-man crew accomplished that in half a day. I withheld submitting a review for 2 months until I could see if it fixed the problem. Over the July 4th weekend we got 9 inches of rain. The basement was bone dry. So I was pleased and impressed. The guys from Anchored Walls are experienced and know what they are doing. FIVE STARS!

Anchored Walls of Winterset stabilized our Basement walls, leveled our driveway, and found an incredible and invisible solution to our 25 year sump pump drain exit. Matt Clayton was consistently kind and patient. He nailed our estimate and was Readily available for questions before, during, and after the project. Debbie was quick, responsive, and friendly to give us speedy and accurate answers to many questions. Finally, Brad was the man who finally solved our 25 year sump pump problem. He was super respectful with my wife, and somehow installed 30 foot of PVC into our yard, leaving zero evidence. You're work is amazing and we are more thankful for you than we can express! All this to say, we strongly recommend and refer Anchored Walls of Winterset. Great job and God bless you for your Efforts.

Benefits of Basement Waterproofing
A dry basement means one less thing to worry about when Iowa weather turns wet. Once you get unwanted water under control, you can stop planning around the next leak and start enjoying your downstairs spaces more.
- Helps Control Moisture: A basement should not feel damp every time you walk downstairs. Keeping unwanted water under control helps reduce the moist conditions that can support mold and mildew growth.
- Protects Your Belongings: You should not have to move boxes off the floor whenever heavy rain is in the forecast. Waterproofing helps keep stored belongings, furniture, and other items safe.
- Makes Your Basement More Usable: A dry basement means better storage, room for hobbies, and more confidence in future finishing plans.
- Protects Your Investment: Addressing recurring basement water prevents moisture damage to finishes and other work you've invested in your downstairs spaces.

“Gabe & Taxson did a wonderful job of waterproofing our basement. They worked so hard chiseling concrete, carrying it up the stairs in buckets, then carrying rock and replacement cement down the stairs to fill in the dug up places, but most of all, they cleaned up the mess!

Frequently Asked Questions
Why does my home have a wet basement?
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.
What will happen if I don't get rid of basement moisture?
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
Why does my basement only leak when it rains?
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.
What’s causing that musty smell in my basement?
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.
Is a crack in my foundation something to worry about?
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.
How can I tell if the issue is interior or exterior water intrusion?
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.
Do I need to waterproof my basement before finishing it?
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.
How much does basement waterproofing cost?
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.
