Air Quality Testing
& Remediation in Colorado
Indoor air quality tests discover invisible airborne toxins.
Small Particles, Big Problems
Air pollution leads to serious health consequences
Exposure to airborne contaminants like Radon and Asbestos increase risk for respiratory illnesses & cancers.
Moisture control is crucial to property management.
Mold thrives in moist conditions and spreads quickly if unchecked, threatening the structural integrity of your property.
Testing is the only way to measure air quality.
The naked eye and nose can’t adequately detect unhealthy air. We use state-of-the-art equipment to accurately detect unwanted air particles.
Indoor Air Quality
Challenges in Colorado
Cold Winters & Hot Summers
Our climate tends to keep homes sealed up for long stretches, trapping pollutants indoors.
Highest Altitude in the U.S.
High altitude means lower oxygen levels, making indoor air quality critical for respiratory health.
Wildfire Risk
Regional wildfires spread smoke & outdoor air pollution throughout the entire state.

Great experience working with the team here. We had a slightly tricky radon mitigation job (old house, many layers, etc.) and they were with us every step of the way.

We used M.A.R.S. Environmental for a complex radon mitigation issue in our historic house, built in 1892. They installed a unique mitigation system that is doing a fantastic job with a difficult basement. Highly recommend!

MARS / Jeanine is a true advocate for a homeowner. In a complex world with interests aligned against full recovery, Jeanine helped us understand what was in our home after the Eaton Fire and provided the appropriate guidance for real remediation.
She is fully committed to safety and doing things the right way. I have referred Jeanine to so many friend at this point and all of them have thanked me for the introduction.
If you are looking for a thorough and comprehensive hygienist then MARS is the choice.

The staff was friendly and helpful from start to finish. They explained the process clearly, the technician answered all my questions on-site, and the results were provided promptly. While the results weren’t ideal, I’m glad I had the testing done and would use them again for future properties.”

What a great company and wonderful people to be helped by. It's a family run business with knowledgeable, caring people who have information, compassion and support - they know the stress and angst that can be there with concerns of environmental issues in our homes. They are patient, kind, helpful and I feel supported knowing they are there for me should I need more help in the future. This itself feels good. I like the personal quality of their communication and business. They did testing for me and explained in detail the results so I feel clear about how to proceed. I highly recommend M.A.R.S. Good to have tested for VOC's and other items they thought needed testing. I wasn't sold unnecessary tests, I didn't feel taken advantage of, or pushed to do things that weren't necessary. All around a good and educational experience considering what it is.
Thank you Jeanine, Lindsay and Brooke. I hope it's okay to use your names! If not, tell me and I'll edit them out!

Jeanine, the owner, demonstrated exceptional expertise in environmental testing after the fire at my house. She provided thorough explanations of how fire and smoke impact homes and air quality, and clearly outlined the necessary steps for restoration. Her professionalism and knowledge were impressive, and I appreciated her informative approach to getting my home back to a safe and healthy state.

MARS environmental is excellent, has great communication, and is reasonably priced. They were able to replace our radon system that was not up to code before we closed on our house.
Highly recommend!

My heart goes out to anyone having to shop for post-disaster environmental testing, but I can enthusiastically recommend Jeanine and her team at M.A.R.S., especially to people dealing wildfire/WUI fire smoke damage.
Our house was in the heart of the Eaton Fire. It was left standing but smoke damaged. For four months, our insurer downplayed the health risks, offering to essentially wet wipe the walls and vacuum our bed after their own test found lead. They didn't address VOCs, SVOCs, heavy metals, though.
We knew that getting our own testing was the only way to push for a more thorough remediation. M.A.R.S came highly recommended by fire survivors in Colorado, also by local word of mouth, even by other industrial hygeniests and folks at United Policy Holders.
Jeanine fit us into one of the weekend trips she'd been doing to the Eaton Fire Scar this spring. And she tailored our tests to address our needs for our claim, and our financial limits. She asked for our prior test results so she could make sure she was only running tests we needed.
On the day, she showed up early. I was thrilled when she said we didn't need to enter the house. Also, her team wore protective gear. (For four months, everyone -- the insurance adjuster, other IH's, and others -- would enter the house casually, often with no masks or PPE, as if it were no big deal. I felt subtly peer-pressured to go in unmasked myself, to take and wash things, and now regret it.)
The results took a while, but the labs have been swamped, and M.A.R.S. was in touch. And when the results did come in, the level of detail and care with which Jeanine laid out her report was remarkable. And her explanations of results rigorously supported her recomendations. She included and referred to all the prior results. And she is up to date on current and emerging science and standards.
In many ways, the new results were bad news (the highest levels of Dioxins she'd seen in the area as well as Beryllium, which we're now learning has shown up in unprecedented levels in the Eaton Soot and Ash), but at least we are now armed with data.
I'm trying to think of constructive criticism, but I really just feel gratitude for Jeanine, Rebecca, and the whole team.
We're still going to have to fight to get the insurance to follow her recommendations so it's all still an ongoing nightmare. That said, the two moments of greatest relief I've felt since the fire were, first, when the M.A.R.S. team showed up at our house, and then later, when Jeannine sent our results. She's smart and talented, and I believe that she does this work because she genuinely cares about protecting people's health. She's a methodical hero :), a literal lifesaver!

I loved how responsive MARS was! I filled out the "contact us" form on their website and heard back via email within 24 hours. We scheduled a same-week appointment. I was emailed an estimate and invoice. They requested a deposit of $100 on a $400 invoice which seemed completely reasonable to me.
I received appointment reminders via text and email. The tester/employee showed up on time and I received a results phone call within 24 hours. I know I'll receive the emailed results within another work day, but they were able to call and give me the peace of mind sooner rather than later.
If you're looking for a quick and professional company, I'd highly recommend MARS Environmental.

Such a fantastic company. They did radon mitigation for a property and knocked it out of the park. It was not an easy space to mitigate in, but they figured out the perfect solution. Timely and price was good as well.

FAQs
Yes, our air quality specialists are well-trained on CDPHE AARST-NRPP, DORA, Dept. of Public Health & EPA guidelines and requirements for any property type, including: single family dwellings, new construction, HUD government housing, and childcare & school properties.
It is important to test for Radon prior to any real estate transaction and then again every 2-3 years to ensure safety and verify that the mitigation system is operating properly.
Anytime you disturb more than 32 sq ft of material, testing should be done, regardless of age of home.
If mold is detected, don’t panic. M.A.R.S. Environmental
can design a custom mold remediation plan to address the source of the moisture problem, remove the mold along with any infected materials, and thoroughly dry the contaminated area to prevent regrowth.
Properties built before 1978 are most likely to contain lead-based paint. If your property was built during this timeframe, testing is recommended whenever you’re planning renovations, repairs, or maintenance work that could disturb painted surfaces. Lead dust caused by disturbance of lead-based paint can lead to serious health risks, especially for children under 6 and pregnant women.
