RTK can test for a wide range of hazards, including mold, lead, asbestos, radon, volatile organic compounds (VOCs), allergens, and general indoor air quality parameters (like particulates and humidity). We also conduct post-fire soot assessments and detect hazards in dust, water, and soil.
Signs include visible growth (often black, green, or white), musty odors, and worsening allergy-like symptoms. However, mold can also grow in hidden areas, so testing is often needed if you suspect a problem.
Very small, isolated patches can often be safely cleaned by homeowners. For larger areas, recurring growth, or health concerns, professional testing is recommended to assess the extent and type of mold.
Air sampling assesses airborne spores; surface sampling identifies mold species on materials and settles spores. We recommend a combination based on your situation.
DIY kits can detect the presence of mold but often lacks the accuracy and interpretation needed for actionable results. Professional testing provides more reliable identification and context.
Yes. Mold can trigger allergies, asthma, and respiratory issues, especially in sensitive individuals. Some molds produce mycotoxins, which can be harmful in any concentrations.
There are no federal standards for acceptable mold levels. The goal is to eliminate visible mold and address moisture sources.
While it might be tempting to clean visible mold yourself, mold often hides in places you can’t see. Professional inspectors use specialized equipment and techniques to detect hidden mold and assess the full extent of the problem. DIY kits are often unreliable, so for peace of mind and a thorough evaluation, it’s best to have a certified inspector conduct a comprehensive mold assessment.
You should consider mold testing if you see visible growth, notice a musty odor, or if anyone in your home is experiencing allergy-like symptoms. Testing is also recommended after water damage (like a flood, leak, or sewage backup), if you’ve had an ice dam on your roof, or if you’re buying or selling a property. Professional testing ensures you get accurate, actionable results.
It’s best to keep testing and remediation separate. Using the same company for both can be a conflict of interest—some companies might exaggerate the problem to increase remediation costs. In fact, in New York State, it’s now illegal for the same company to do both on the same job. Choose an independent, certified testing service for an unbiased assessment.
Not all black mold is toxic. While certain types of black mold can cause serious health issues, all molds—regardless of color—can trigger health problems, especially for people with allergies. The safest approach is to have any mold professionally tested to determine the type and risk level.
No, the color doesn’t indicate how dangerous mold is. There are over 100,000 types of mold, and only laboratory testing can identify them. If you find any mold, it’s wise to have it tested and assessed by a professional.
Yes, mold exposure can cause a variety of health issues, from mild allergy symptoms like coughing and headaches to more serious problems such as asthma or skin rashes. Toxic molds can have even more severe effects.
Homes built before 1978 are at higher risk. Deteriorating paint, dust, or soil in older properties may contain lead. Testing is the only way to confirm.
Yes. Testing is strongly recommended before renovation, repairs, or if you have young children, as lead exposure is especially dangerous for them.
Some are EPA-recognized for the top layer of paint, but professional testing is much more accurate and can assess levels of paint below the surface, dust, soil, and water as well.
Avoid disturbing the area, keep children away, and consult with certified lead abatement professionals for safe removal or encapsulation.
Lead poisoning occurs when lead enters the body, usually through inhalation or ingestion of lead dust, contaminated water, or paint chips. It’s especially dangerous for children under 6, as it can cause permanent physical and mental developmental issues. At very high levels, lead poisoning can be fatal—but it is preventable.
The most common source is inhaling or ingesting lead dust, which is often found in homes built before 1978 (when lead-based paint was banned for residential use). Lead can also be present in old pipes, soil, and even imported food cans.
Testing is crucial if your home was built before 1978, contains old plumbing, or if you’re planning renovations that could disturb painted surfaces. Disturbing old paint can release hazardous lead dust.
Lead dust is created when lead-based paint is sanded or chipped, often during renovations. It’s highly toxic, especially to children, and can spread easily throughout a home. To protect your family, have your home professionally tested for lead dust, especially if you live in or near older properties.
While lead poisoning can cause symptoms similar to autism, there is no definitive evidence that it causes autism itself. However, lead exposure can result in serious developmental and behavioral issues.
Asbestos may be present in insulation, floor tiles, ceiling tiles, roofing, siding, pipe insulation, and many other building components, especially in properties built before the 1980s.
You cannot tell by sight alone—testing is required.
No. Disturbing asbestos-containing materials can release dangerous fibers. Always hire a certified professional for sampling.
Many uses were banned in the late 1970s and 1980s, but older materials may still be present. Testing is the only way to know for sure.
If the material is intact and undisturbed, it may be left in place and monitored. Damaged or deteriorating materials should be professionally removed or encapsulated.
Yes, especially if the home was built before 1980. Asbestos was widely used in building materials until it was phased out, and it can still be present in older homes. Professional asbestos monitoring testing is essential before purchasing or renovating older properties.
If you’re planning renovations that might disturb asbestos-containing materials, removal is necessary before any work begins. However, if the other materials are in good condition and undisturbed, they’re generally safe to leave alone.
Intact vinyl asbestos floor tiles are typically safe if they aren’t damaged or disturbed. However, removing or damaging these tiles can release hazardous fibers into the air, posing serious health risks. Always consult professionals for safe handling and removal.
Symptoms include headaches, fatigue, respiratory irritation, worsening allergies, musty or chemical odors, and visible dust or mold.
Common tests include mold, VOCs, particulates, radon, and allergens.
No. IAQ assessments are tailored to your concerns and may involve multiple tests.
Test if you notice symptoms, after renovations, water damage, purchasing furnishings or every few years as a precaution.
Yes, for some contaminants (like lead or asbestos). For others (like mold), guidelines recommend minimizing exposure.
Test your indoor air quality if you or others experience unexplained health issues such as allergies, headaches, nausea, or skin irritation. Testing is also important after renovations (which can release asbestos or lead dust), or after events like floods, fires, or pest infestations. A professional inspection can identify the root causes and provide actionable recommendations.
Most indoor air quality issues are caused by high levels of volatile organic compounds (VOCs) and mold spores. VOCs can come from paints, cleaning products, carpets, furniture, pesticides, and building materials.
Absolutely. Poor air quality can worsen allergies and asthma, and may also cause headaches, fatigue, and general discomfort. If you notice your symptoms worsen in a particular location, indoor air quality testing is recommended.
Sick building syndrome is a condition where building occupants experience health issues linked to time spent indoors. It’s often caused by poor ventilation and the buildup of contaminants like VOCs and mold.
Contaminants like bacteria, lead, arsenic, radon, and pesticides can be present in well water, often without any noticeable taste or odor. The CDC recommends annual testing for common contaminants, or any time you notice a change in your water’s color, taste, or smell.
At a minimum, test your water once a year for bacteria, nitrates, total dissolved solids, and pH. Every few years, test for additional contaminants. If you use municipal water, review the annual water quality report. For well water, check the well’s condition each spring.
Once you reach out to RTK, one of our local team members will contact you quickly to go over details of your issue, answer any questions, and give you a quote. Most inspections take 1–3 hours, depending on the size of the property and the number of tests required. Results are typically available within 2–7 business days, depending on the type of analysis.
Testing (or consulting) identifies and assesses hazards. Remediation is the process of removing or correcting those hazards. RTK provides testing and unbiased recommendations; remediation is performed by specialized contractors.
We can usually schedule within a few days. Most results are ready in 2–7 business days.
Our inspectors are certified by recognized bodies such as the American Council for Accredited Certification (ACAC), National Association of Mold Remediators and Inspectors (NAMRI), and state-specific agencies.
Most testing is non-invasive and causes minimal disruption.
Clear access to areas of concern, all windows and exterior doors closed, and avoid cleaning or disturbing surfaces for 24 hours prior to testing. Specific directions will be given prior to your test.
RTK provides a detailed report, explains the findings, and recommends next steps. If hazards are found, you hire separate remediation professionals. To ensure the job was properly completed and the mold was fully removed, we often return to conduct clearance testing after the remediation is complete. If you have a specific situation or concern, feel free to ask for more tailored advice.
RTK has been a trusted partner for environmental testing and consulting for 30 years. We only perform testing and never remediation, so there is no conflict of interest.
We provide environmental testing services to the New York tri-state area, including all of Connecticut, northern New Jersey, New York City, Long Island, and the Hudson Valley.
Yes. RTK provides lead paint testing for New York’s Local Law 31, which states that by August 2025, all pre-1960 buildings must undergo comprehensive X-ray Fluorescence (XRF) testing for lead paint in dwelling units and common areas by an EPA-certified lead inspector.
