“Courtney was awesome! We weren’t sure what was causing our moisture issue, Courtney was very thorough in her investigation and considered all sources. She clearly explained all of our options. She was meticulous in making sure our issue was resolved. Feel she went above and beyond to make sure every possibility was covered.”
“Courtney was knowledgeable and helpful. We were satisfied by her services and results.”
“Courtney was wonderful. She inspected and tested my house for mold and was very knowledgeable. She also provided me with multiple resources that I found very helpful, and I am very appreciative.”
“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!”
“I’m so pleased with Pure Maintenance- Courtney was clear with the process and testing post treatment gave me peace of mind. Highly recommend!”
“Wow, What a difference in the air quality. We bought our house a few years ago and had mold and we didn't know what to do about it. I kept trying different things and nothing seemed to work. Finally, I got a hold of Pure maintenance figuring why not I've tried everything else. She explained the mold differently than anybody else had before...that It travels through the air and that we had to get rid of the source of the problem first. She found the source and took some mold readings which were high. We followed her instructions on how to fix where the water was coming in, she came and treated our home. It took a bit on our part but it was woth it because the problem went away after her treatment. Not like anything we tried before, which never worked. It's so different in here. No more mold smell every time I walk into the house. I have new hardwood floors that I can now smell them. And we just feel so much better, as far as our health. We couldn't be more appreciative. I wish we were called Pure Maintenance to begin with. Thanks Courtney! Mary”
“We had a freezer disaster at home, and hundreds of pounds of pork, beef and shrimp have been rotting for days while we were gone. The smell was absolutely sickening and unbearable. Nothing got rid of it. I tore up the carpet, bleached the subfloor, used baking powder, ran fans for days, ran an ozone generator for hours on multiple occasions, nothing made a difference. Courtney came over with her equipment, fogged the room, and the very next day the smell was completely gone. Weeks later, the room smells fresher than before the incident. Thank you!!!!”
“We had a very significant mold problem, and Courtney is very knowledgeable, answered all our questions, was very thorough, and had excellent follow up. The fogging was very effective given that our kids had no more symptoms following the treatment. We had this done following a more invasive mold remediation as a way to remove any spores in the areas and on the surfaces that couldn’t effectively be covered with other methods. She definitely went the extra mile. Highly recommend!!”
Madison sits on a narrow strip of land between Lake Mendota and Lake Monona — making it one of the more humidity-prone environments in Wisconsin. That persistent ambient moisture can cause mold to develop in homes that might otherwise be unaffected, and it accelerates existing mold problems significantly.
Add in Wisconsin's harsh winters — which drive condensation into attic spaces, create ice dams that push water under roofing, and produce freeze-thaw cycles that stress foundations and building materials — and mold becomes a near-universal issue in older Madison homes.
By the time visible mold appears on a wall or ceiling, spores have typically been accumulating throughout your air and building materials for months or years. A surface cleaning or localized spot treatment won't resolve that. The mold sources and the full extent of contamination both need to be addressed.
Pure Maintenance Wisconsin provides comprehensive, full-service mold remediation for homes and businesses across Madison and Dane County. We inspect, remove affected materials, treat your entire interior with patented vapor technology, and verify results — restoring healthy air quality for the long term.
Most mold companies do one of two things: tear out visible mold and leave, or apply a wet fog treatment that coats nearby surfaces without fully penetrating the interior space of the home. We do neither. Pure Maintenance Wisconsin takes a whole-home approach. That means:
Visual inspection and sampling. We begin with a visual inspection of the home, taking samples where we see it's warranted. This gives us a picture of the extent and severity of the problem and informs our plan.
Removing mold sources. When mold has penetrated building materials — drywall, insulation, wood framing, subfloor — those materials need to come out. We do that work. We avoid unnecessary demolition, which keeps your costs down.
Treating the entire home with patented vapor technology. Unlike wet fog methods, our patented vapor technology uses positive air pressure to fill the interior space of the home with an EPA-registered sterilant at a precise particle size. Rather than condensing on surfaces, it remains suspended and circulates throughout — treating mold in the air and on surfaces throughout the home.
Verifying the results. Results are confirmed through post-treatment air and surface sampling, analyzed by an independent third-party laboratory or inspector. You receive a written report.
Our approach to mold remediation can be broken into four simple steps.
We will survey your property and identify the likely source(s) of the mold. Our team understands how mold works in a building, and the common sources of mold and moisture. We will use a range of tools and techniques to identify the cause.
We work with you to make a custom plan for your particular situation. Part of the plan is to help you resolve the source that is causing the mold. After the source is eliminated we use our patented vapor technology, as well as other sanitation methods, to clear mold and spores in the building.
Our antimicrobial application is applied to surfaces, creating a covalent bond. It helps prevent mold from returning to treated surfaces and keeps the overall spore load of the building down by electrostatically attracting ambient spores and denaturing them on contact.
Agitated air & surface samples taken in various areas of your home are analyzed by independent, third-party laboratories to demonstrate quantitative markers of mold reduction. Your house is warrantied for mold.
Even after thorough physical remediation, mold spores remain in your air and embedded in surfaces. Traditional wet fogging methods distribute larger droplets that condense on nearby surfaces or burst in the air, resulting in patchy, unpredictable coverage. Much of the airborne mold goes untreated.
Our patented vapor technology works differently. The sterilant is condensed to a precise particle size using positive air pressure. At that size, it doesn't condense on surfaces — it remains suspended, circulating through the home until the entire interior space is treated.
Critically, the vapor behaves like humidity — it penetrates porous materials rather than simply coating surfaces. Independent lab studies have shown it can penetrate five layers of cotton and achieve over a 99.99% kill rate in just 30 minutes. That means it reaches mold in building materials, not just on them.
The result:
Our vapor process is backed by independent peer-reviewed studies and US Army Corps of Engineers testing. Post-treatment lab reports give you documented proof of results.
Getting mold and spores out of the air and interior of an entire home through demolition alone would be prohibitively expensive. Our vapor technology makes whole-home remediation practical and affordable.

Frequently Asked Questions- Mold Remediation in Madison, WI
Common signs include a persistent musty odor, visible dark spots on walls or ceilings, unexplained health symptoms such as congestion, fatigue, brain fog, or allergies, a history of water leaks or flooding, or elevated indoor humidity. Air sampling is the most accurate way to confirm mold levels and species.
Yes. When mold has penetrated building materials to the point they need to come out, we remove them. We do the demolition that's necessary — and we avoid the demolition that isn't, which keeps costs down compared to traditional spot-treatment approaches.
Wet fog or mist treatments use larger droplets that condense on nearby surfaces or burst in the air, resulting in patchy, uneven coverage. Much of the airborne mold is left untreated. Our patented vapor technology condenses the sterilant to a precise particle size that remains suspended — circulating throughout the entire interior space of the home for thorough, consistent treatment.
Yes — as long as sources are removed and no new moisture issues develop. If no new leaks, humidity problems, or improperly managed demolition occur, the mold will not return. If a new leak occurs within the first year, we offer a free re-vapor treatment — so consider the vapor treatment a one-year investment in your home's air quality.
Cost varies based on the size of the home, severity of contamination, location of contamination, and how much physical remediation or demolition is required. Because we avoid unnecessary demolition and our vapor technology treats the entire home efficiently, our approach delivers whole-home results at a fraction of what comparable coverage would cost through conventional methods alone. We provide accurate estimates after an in-person assessment.
Vapor treatment is typically completed within a day. Physical remediation varies by scope. We'll give you a clear timeline as part of your plan.
Yes. Our vapor sterilant is EPA-registered and non-toxic — safe for people, pets, and plants once completed.
Homeowner's insurance typically covers mold remediation when the cause was a sudden, unexpected event— such as a burst pipe — where moisture is still present and detectable. Pre-existing or long-term moisture issues are generally not covered. We can provide documentation to support your claim.
