i am writing to provide the highest recommendation for MARS environmental. I suffered an electrical fire that left my house in-tact but we knew that there was toxic residue left by this fire, our insurance company wanted to do simple cleaning - we turned to MARS and had them do a full test of our house. They were professional, timely and the report they produced was exhibit #1 in our battle with the insurance company. It is important to know that MARS reports the facts, it is not subjective or legal positioning and the facts fully supported a full tear down of our structure. If we had only cleaned, our health would have been compromised and that is what the insurance company wanted to do. Jeanine and the MARS team are very professional, responsible and i would give them my highest rating for any situations that involves assessing environmental chemical issues. Signed - very happy in Montana

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.

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!

Just hired MARS environmental to do a meth test for a home we have under contract. They got me setup with an appointment fast. The tester arrived on time, was friendly and explained everything. I recommend!

1 year ago

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.

Skipping post-fire clean-up in your home can lead to devastating consequences:

Health Risks

Exposure to soot and smoke particles can cause respiratory issues, cancer, and other diseases.

Loss in Home Value

Lingering smoke damage can decrease property value and make selling difficult.

Structural Damage

Soot and acidic residues continue to deteriorate walls, furniture, and HVAC systems if left untreated.

What Is Smoke and Soot Testing and Why Is It Important?

After a fire, microscopic soot, smoke residue, and harmful chemicals can settle into walls, insulation, HVAC systems, and furniture, posing serious health risks — especially for children, the elderly, and those with respiratory conditions. M.A.R.S. Environmental’s industrial hygienists conduct thorough testing to ensure your home is safe before you return.

Smoke Testing and Remediation Services in Colorado

Colorado’s dry climate makes it particularly susceptible to wildfires. M.A.R.S. Environmental has been helping homes affected by the 2021 Marshall Fires get back to pre-fire condition & make them safe for habitation.

Smoke Testing and Remediation Services in Nebraska

Though Nebraska wasn’t historically a particularly fire-prone state, climate change and drought conditions have brought year-round wildfire risk to the state, especially during fall harvest and hunting seasons. M.A.R.S Environmental helps Nebraska homeowners ensure their homes are safe to reenter after fire or smoke damage.

Smoke & Soot Testing Frequently Asked Questions

1. How soon should I have my home tested after a fire?

As soon as possible! Smoke and soot can settle quickly into surfaces, making cleanup harder the longer you wait.

2. Can I clean soot and smoke damage myself?

To limit risk of exposure to toxigenic chemicals it is highly recommended to use professional remediation.

3. How long should I wait before returning home after a fire?

You should wait until you receive clearance from an independent testing professional. In addition, certain regulations require you wait to return/begin cleaning until the surrounding area is cleared to prevent reintroducing toxins.
