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.

Mold: A Microscopic Fungi that Causes Major Problems

Mold spores produce toxins,
allergens & irritants

Exposure to mold spores can lead to chronic allergy-like symptoms, asthma, brain fog, bloody noses, cough, headaches, and sinus infections.

Mold grows rapidly in moist conditions

Uncontrolled moisture and mold growth eats away at your property, quietly destroying drywall, insulation, and any structural component made of wood.

Testing is the only way to detect mold

Visual identification can be misleading because mold appearance varies widely by color, from green & black to orange & pink. We use state-of-the-art equipment to accurately detect any type of mold.

Colorado Standards & Regulations for Mold

Colorado Testing Standards

Colorado does not have state-mandated certification or licensing requirements for mold remediation professionals. Homeowners should verify any company they hire follows recognized industry standards.

Tenant Laws

The Colorado Residential Tenants Health & Safety Act requires landlords to address suspected mold complaints within 96 hours, and remediate within 7-10 business days after testing detects mold.
Tenants can file a complaint with the county health department or seek legal representation if a landlord fails to address a mold problem.
It is unlawful for landlords to retaliate against tenants who report unsafe living conditions or request repairs associated with mold.

Real Estate Laws

Mold is considered a “latent defect” so sellers are legally required to disclose any history of mold or remediation.
Per the Colorado Division of Real Estate, realtors must disclose toxic mold to potential buyers.
Water-related problems, including mold, are the most common causes of real estate disclosure lawsuits.

Nebraska Standards & Regulations for Mold

Nebraska Testing Standards

Nebraska doesn’t require certification or licensing for mold testing or remediation. Homeowners are responsible for ensuring anyone they hire is qualified and follows industry-recognized standards.

Real Estate Laws

Nebraska Revised Statute 76-2,120 requires sellers of residential property to provide buyers with a written disclosure statement of the property’s condition.
The disclosure must include conditions that “may be an environmental hazard,” which could include mold.

Testing is the ONLY way to know if mold is a threat to your
health, your family, and your property.

Mold Testing & Removal FAQs

1. What is mold testing?

Mold testing assesses the presence and extent of mold growth inside your property through air and surface sampling. The process detects mold, identifies the type of mold, and determines the spore level.

2. What causes interior mold?

Mold needs moisture to grow and spread. Therefore, common causes of mold within your property include: leaky pipes or plumbing, poor ventilation, flooding, and high humidity.

3. When should I test for mold?

If you see suspicious growth or recognize any of the warning signs listed above, professional testing is the only way to confirm the presence of mold. If you’re planning on purchasing a new property, mold testing is recommended to safeguard the investment and prevent any bad surprises after closing.

4. What should I do if mold is detected at my property?

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.

5. Do I need to move out during mold removal?

Probably not. During a typical remediation, most customers remain at the property and function normally everywhere except the containment zone.
