At Pure Maintenance of Colorado, our first priority is the same is yours: A safe and clean home or business. Using the science of patented dry-fog technology in concert with IICRC S520 and NORMI remediation standards, we combat mold at the cellular level. Our patented InstaPURE fumigation process will kill AND denature mold and other harmful pathogens so they can't reproduce or produce toxins, leaving your home safer and healthier. Then we complete our patented EverPURE process to inhibit future microbial growth. Our process allows us to treat any home or business without unnecessary demolition and time out of your home, saving you both time and money. Is there mold in your walls or floors? Because our fog particle is smaller than a single mold spore, if water or mold can get there, our fog will get there too! Plus we offer a full 12-month warranty on all qualifying projects! Most effective. Most affordable. Best guarantee.

"We hired Pure Maintenance of Colorado after another remediation company failed to properly contain mold during cleanup. Pure Maintenance was everything we needed — professional, knowledgeable, compassionate, and extremely thorough. They spent three full days deep cleaning, doing small-particle removal, and fogging the entire house and ventilation system. What truly matters is the outcome: the air in our home feels fresh and clean, and our child, who has mold sensitivities, has had no reactions since the treatment. The difference is night and day. We are sincerely grateful and give Pure Maintenance of Colorado our highest recommendation."

When you have mold, making the correct decisions right away is critical. Whether it is mold in your home, school, place of work, or apartment there are many factors to consider. Are you going to be involved in a mold lawsuit? Will you be seeking property damages? Is anyone sick from mold exposure? Will you be seeking medical damages? Will you need expert witnesses? If so, what kind? Do you just want to test to be sure your environment is safe? Do you need post mold remediation testing to ensure a good job was done? These and other factors are questions which need to be answered before any environmental testing starts. It is important to know what your goals are and why your testing. Different goals require different environmental tests, i.e. medical damages and property damages require different environmental tests to prove your case in court. Tests that a common, or inexperienced, mold inspector would not typically use or know to use.

"We bought an older home and several windows were letting in the winter draft. We decided this past year to have the windows replaced. From the consultation appointment to installation this company was completely professional. We did not feel forced into buying and the installers did an exceptional job. Our house stayed much warmer this winter. We will be using Renewal again!"

Mold Testing and Remediation questions, answered by experts

Mildew and mold are not different—mildew is a specific type of mold and yes, it can become dangerous if left untreated. It would be amazing if we were all biochemists but because we most likely aren’t, it isn’t wise to assume any mold is mildew on sight alone. Harmless mold and toxigenic mold (which can be deadly) look very similar, so if you see any new mold that looks even a little suspect, call a mold professional immediately.

Visible growth, musty odors, and water damage are common indicators.

According to the EPA, mold grows within 24 to 48 hours if left untreated after a water leak. So unless you notice the leak and stop it right away, you only have a day or so before mold is a real concern. If you don’t notice the leak, it can take about three weeks for the mold spores to become visible. That means you’ve likely had an active mold infection for a few weeks by the time you notice discoloration.

Mold doesn’t take long to form, especially in dark, isolated areas like under the floorboards, where you’re less likely to know it’s wet in the first place. Mold can take root and proliferate in just 24 to 48 hours, but it can be up to a week before you start to notice funky smells. 

While goats can eat poison ivy and other plants that are harmful to humans, this doesn’t mean they can eat anything. Certain plant species, like azaleas, sumac, nightshade, Virginia creeper, and more, can kill goats. If your property has any of these plants, it won’t qualify for goat rental services. Most rental companies will ask for pictures or videos of your property or even inspect your land themselves to ensure none of these plants are present.
