"I was affected by the August 9th Milwaukee flooding. Lost everything and ended up with mold. Courtney and her crew Ivan, Broodie any Anthony Rock! Very nice and honest people. Excellent customer service experience from the first initial quote estimate Courtney was very professional, very knowledgeable, very thorough with her inspection. Her crew did an amazing job with the mold remediation, demolition of drywall and cleaning of the mold on concrete walls. Very informative throughout the entire process. The results were awesome, you can't even tell mold was there. If anyone have mold I highly recommend you contract with Pure Maintenance. FIVE STARS PLUS!!"

"I highly recommend Pure Maintenance Wisconsin! They made a very stressful situation of discovering black mold in our home, causing severe mycotoxin illness, a seamless and stress free process.Courtney is amazing! She and her team are excellent at communicating, and are very detailed in explaining the process. Courtney is the 1st person to be certified in Wisconsin with this specific type of mold remediation! It’s cutting edge. They removed literally every spore from our space.Unfortunately, as a population, we are not educated about mold and its dangers - that it can cause cancer, for example. Most mold remediation is inadequate & does not actually remove the dangerous spores from your space. Courtney is an expert and can be 100% trusted. My doctor’s office even uses her company. Thank you, Courtney!"

"Courtney was extremely knowledgeable about mycotoxin illness and the steps that needed to be taken to remediate my condo - including dealing with odd schedules and an inflexible HOA. For tasks outside of Pure Maintenance's specialty, she recommended other skilled local professionals who also did their jobs quickly and well. I highly recommend this company."

"I was very impressed with Pure Maintenance Mold Removal. I have the HLA genotype that doesn’t form antibodies to the mycotoxin that mold spores produce, and therefore I get pretty sick from a mold exposure with CIRS symptoms. Our basement was flooded in August and after initial remediation from an emergency company, I was still experiencing symptoms. I had heard about Pure Maintenance from a health podcast and felt fairly convinced that they would make my home healthy again. Customer service was excellent and prompt, communication was clear. Courtney (the owner) came to my home and pointed out areas that still needed remediated. She was very detailed as she went through my home, searching for potential mold spores. She and her team came in and completely removed any potentially remaining mold, using negative air pressure to ensure the spores did not infiltrate the rest of my home. After they were confident they removed all of the mold spores, they treated my entire home with their dry fog which completely neutralizes the air. They tested the air after their work and levels were at zero. When I came back into my home after their work, the air was so fresh and clean. I no longer had symptoms from the mycotoxin exposure and feel healthy again. Courtney is extremely detail oriented and is an expert in mold remediation. She is honest, and collaborates with her clients on the best remediation approach. My only regret is that I didn’t hire Pure Maintenance right away after the flood to do the initial remediation. I highly recommend them!"

"I cannot stress enough how wonderful Courtney and her team are. She is data driven-- your quote will be based on mold being tested for rather than eye balling where they think mold could be. Additionally, they do all of this without being condensing in any way, encouraging questioning the process/ how things work.

For results-- my partner and I had recurring sinus infections that have gone away once treatment was completed. We've also both had less headaches."

"Courtney from Pure Maintenance was awesome!

I was completely ignorant about mold and when I found out we had a mold issue I was horrified and had no idea where to even begin. Pure Maintenance was recommended to me and I'm so glad as they made the process of mold remediation so straightforward and easy.
On her first visit, Courtney walked me through the science side of things and was able to accurately find and diagnose the source of our mold problem. I have a child with asthma so I was eager to act as quickly as possible--Courtney was able to squeeze us into her schedule the same week which was great for my peace of mind. She was able to treat our house in one day: we left home in the morning with a mold problem and returned home after work to a mold-free home.
And of course the science backs it up! Courtney shared detailed results of before and after treatment and the facts speak for themselves.
It can be so difficult to find professionals that you trust to do work in your home, especially with an issue as serious and delicate as mold remediation. I would absolutely recommend Courtney and Pure Maintenance without hesitation. They delivered the promised results quickly and without hassle which is the best I could ask for. Thanks again Pure Maintenance!"

"Courtney made sure the job was done right. I've had less knowledgeable so called "mold experts" assess my home and they failed. She found where the mold was hiding and made an extra effort to be sure it was identified and properly remediated. I"m now breathing much better and relying less and less on my medication."

"Courtney and the team were so helpful! After a renovation of our basement we thought all the mold was gone. Courtney came in and investigated until she found spots we hadn't thought about. She kept working with us until we eradicated the mold entirely! The demo'd a few spots that were too saturated with mold, dried out anything that could be salvaged, and applied the vapor. Very effective process that was much less expensive than redoing our basement stairs and more walls! It's been so nice to have our house back!"

Accreditations & Certifications

Something smells musty in your house and it seems to come from the floor. Maybe the humidity feels off, or your allergies have been flaring up for weeks even though you've cleaned every visible surface. If your home has a crawl space, that's usually the first place to look, and in Madison it's where most of these problems start. We handle crawl space mold removal across Dane County and can usually get to you within a day or two.

When you need crawl space mold removal

Most people never set foot in their crawl space, so mold down there gets bad before anyone notices. The signs tend to show up in your living space first. A musty smell you can't pin to any one room. Floors that feel cold or damp. Indoor humidity higher than it should be. Allergy symptoms that don't clear up no matter how much you clean. If you do take a look, you'll usually see mold on the floor joists, the subfloor, the vapor barrier, and the insulation.

Madison crawl spaces see a lot of this. Plenty of homes around the lakes and in older parts of town sit over a crawl space rather than a full basement, and the same goes for a lot of additions and cottages out toward Waunakee, Stoughton, and Cross Plains. The climate here does not help. Summer dew points sit in the upper 60s and 70s for weeks, which is more humid than people realize. Then you get spring snowmelt pushing groundwater up, and a water table that stays high near Lake Mendota and Lake Monona well into July. Older houses often have a bare dirt floor under there, or a vapor barrier that has torn, lifted, or pulled apart after a few Wisconsin winters of freeze and thaw. Once that happens, soil moisture rises straight into the space beneath your floors.

Our crawl space mold removal process

Crawl spaces are one of the hardest areas in a home to treat the traditional way. Low clearance, tight access, exposed soil, insulation between the joists, ductwork, and plumbing. Scrubbing or spraying every surface by hand is slow, and a lot of remediation companies won't even quote the job without tearing the insulation out first.

Our patented VaPURE process was built for exactly this kind of space. An antimicrobial sterilant fills the entire area, across joists and subfloor, around pipes and ducts, and into the gaps where mold hides. It kills mold on surfaces and in the air without anyone needing to crawl into every corner with a brush. A second stage lays down a protective coating that bonds to surfaces and helps stop regrowth. We also check what's keeping the space wet in the first place: the vapor barrier, drainage, grading, and ventilation. That way you know what needs fixing long term, not just what to clean up today.

Crawl space mold removal cost in Madison

Traditional crawl space remediation gets expensive fast. Workers spend hours or days in a three-foot clearance, stripping insulation, hand-treating surfaces, then putting it all back. Labor is the biggest cost and it adds up quickly.

Our VaPURE process reaches the whole space without that much manual work, which cuts both time and cost. What you pay depends on square footage, access, and the condition we find the space in. We inspect first and give you a fixed quote before any work starts. Most homeowners are surprised at the number when we price it out. You won't get billed by the hour, and you won't see surprise add-ons on the invoice.

Why choose Pure Maintenance Wisconsin

Crawl spaces are where VaPURE really earns its keep. No traditional method can treat a space this cramped without a lot of demolition. Our sterilant reaches every surface no matter the clearance or access, and the protective coating helps keep mold from coming back in a space that's always going to get damp to some degree.

Every job is backed by independent lab testing, and we guarantee your indoor mold levels will be lower than outdoor levels. If they're not, we come back and retreat for free. Crawl space mold is one of the most common jobs we handle around Madison, so we know this housing stock, the soil, and the winters it has to deal with.

If you think there's mold under your house, don't leave it. The air in the crawl space ends up in the rest of your home one way or another. Call Pure Maintenance Wisconsin at 608-893-6620 for an inspection and an honest read on what you're dealing with.
