Who We Help

Test My Home works with a specific type of client. People who understand that environmental exposure is real and measurable, and want expert clarity on how their home may be influencing health outcomes.

Chronically Ill or Medically Complex Clients
You have worked with doctors, specialists, or functional practitioners, yet symptoms persist or fluctuate. You want to understand whether factors such as mold, air quality, water contamination, or EMF exposure are contributing, and you need this evaluated carefully, objectively, and without alarmism.
Health-Optimized Homeowners & Biohackers
You actively invest in your health, performance, and longevity. You want your home to support sleep quality, nervous system regulation, recovery, and cognitive function, and you are looking for precise data and expert interpretation rather than generalized wellness advice.
Buyers, Renovators, and Second-Opinion Seekers
You are purchasing, renovating, or remediating a home and want expert insight before making decisions that are difficult or costly to reverse. This is particularly important when buying a home, where environmental conditions are often unknown. We help clients assess risk, interpret testing, and evaluate remediation plans with clarity and context.
Practitioner-Referred and Health-Led Clients
You are working with a functional, integrative, or environmentally informed practitioner who suspects environmental exposure may be relevant. You need credible testing, clear prioritization, and findings that can be meaningfully integrated into your care plan.

We Don’t Just Test. We Investigate.

A test kit gives you numbers. We give you answers. Our certified investigators combine advanced testing with years of field expertise to reveal what’s truly happening inside your home. From hidden mold to unseen EMFs, we know where problems hide and how they connect to your health. It’s this deeper investigation that transforms data into direction.

Protecting Your Health at the Source

What We Test For

From mold and EMFs to chemicals and water contaminants, we uncover the hidden factors impacting your health.

Mold is one of the most common — and overlooked — indoor threats. Found in walls, attics, basements, crawlspaces, and HVAC systems, mold doesn’t just look bad; it produces spores and mycotoxins that can impact nearly every system in the body. The biggest challenge? You often can’t see the mold that’s making you sick — which is why investigation is more important than lab numbers alone.

  • Hidden mold growth is often the root cause of fatigue, brain fog, chronic sinus issues, and skin irritation
  • Mycotoxins released by certain molds are linked to neurological symptoms and long-term illness
  • Mold often spreads behind walls or under flooring where air tests alone may not detect it
  • A thorough inspection by a trained investigator can reveal patterns and sources that simple DIY kits miss
  • Identifying both visible and invisible mold allows you to fix the root cause and prevent recurrence

Your home is filled with invisible electrical and wireless signals — from WiFi routers to cell towers to smart devices. These electromagnetic fields (EMFs) are often overlooked but can have a profound impact on health, especially with chronic exposure.

  • Everyday sources: WiFi, Bluetooth devices, cell phones, smart meters, baby monitors, and nearby towers
  • Biological impact: Research shows EMFs can affect sleep quality, nervous system function, and cellular stress
  • Sensitive groups: Children, those with chronic illness, or people struggling with fatigue and insomnia are often most impacted
  • Hidden hotspots: EMFs tend to be highest in bedrooms and workspaces, where long hours of exposure compound the effects
  • Scientific concern: The International Agency for Research on Cancer (IARC) has classified radiofrequency EMFs as a possible carcinogen
  • Our investigation: We measure EMFs across multiple frequencies (low-frequency, high-frequency, dirty electricity) and identify safe vs. high-risk zones in your home

By pinpointing EMF hotspots, we give you clear strategies to reduce exposure — protecting your family’s sleep, focus, and long-term health.

Even crystal-clear tap water can carry contaminants that impact your health. Municipal systems and private wells alike may introduce harmful chemicals and microbes into your home. Without testing, you won’t know what you and your family are actually drinking.

  • Chemical contaminants: Chlorine, fluoride, pesticides, pharmaceuticals, and industrial pollutants
  • “Forever chemicals” (PFAS): Linked to hormone disruption, cancer, and immune system effects — found in water supplies nationwide
  • Heavy metals: Lead, arsenic, and mercury can leach from pipes and plumbing fixtures, especially in older homes
  • Microbial risks: Bacteria, parasites, and biofilm can persist in water systems and cause gastrointestinal illness and chronic infections
  • Widespread problem: Studies show millions of Americans are exposed to water that exceeds federal safety limits (EWG)
  • Children at risk: Kids are especially vulnerable since their smaller bodies and developing systems absorb more contaminants per pound of body weight
  • Our investigation: We test for the most concerning toxins and metals, and provide clear recommendations for filtration systems that actually work

Testing your water is the first step to ensuring the source you rely on most is truly safe.

Indoor air is often 2–5 times more polluted than outdoor air (EPA). Since we spend about 90% of our time indoors, the air inside your home plays a critical role in health and well-being. Poor indoor air quality doesn’t just cause irritation, it can drive chronic symptoms and long-term risks.

  • Common pollutants: Dust, pollen, dander, mold spores, and combustion byproducts from cooking and heating
  • Chemical exposures: VOCs (volatile organic compounds) from cleaning supplies, paint, furniture, and flooring
  • Health effects: Asthma, allergies, chronic fatigue, brain fog, and even cardiovascular and neurological problems
  • Vulnerable groups: Children, pregnant women, and the elderly are especially sensitive to airborne pollutants
  • Our investigation: We assess particle counts, humidity, VOC levels, and other indoor air factors to uncover hidden issues
  • Solutions: With results in hand, we guide you toward targeted improvements like filtration, ventilation, and material changes

Clean indoor air isn’t a luxury. It’s a foundation for energy, focus, and long-term health.

Modern homes are filled with thousands of synthetic chemicals. Many of these continuously “off-gas” into the air we breathe. These volatile organic compounds (VOCs) and chemical residues often go unnoticed but can quietly undermine health over time.

  • Common sources: Cleaning products, air fresheners, pesticides, paint, flooring, furniture, and building materials
  • Health effects: Headaches, dizziness, fatigue, hormonal disruption, asthma, and long-term risks including neurological disorders and cancer
  • Children at risk: Kids breathe more air per pound of body weight than adults, making them more vulnerable to chemical exposures during critical stages of development
  • Invisible threat: Even “new home smell” is often the result of VOCs and formaldehyde off-gassing from carpets, cabinetry, and finishes
  • Our investigation: We measure VOC levels and identify chemical stressors that could be contributing to chronic symptoms or illness
  • Solutions: From safer product swaps to advanced filtration and ventilation strategies, we guide you in reducing chemical load in your home

Minimizing chemical exposure is one of the most powerful and overlooked ways to protect long-term health and improve daily well-being.

Household Products

Everyday products can be one of the largest sources of hidden toxins in the home. Cleaners, fragrances, and personal care items often contain chemicals that build up in your indoor air and dust, directly impacting health over time.

  • Cleaning supplies: Many conventional cleaners and disinfectants release VOCs and harsh chemicals that irritate lungs and skin
  • Fragrances and air fresheners: Often contain phthalates and synthetic compounds linked to hormone disruption and respiratory irritation
  • Personal care products: Lotions, shampoos, and cosmetics may carry parabens, formaldehyde releasers, and other toxic ingredients
  • Children and pets: Both are especially vulnerable to household chemical exposures due to their size, behaviors, and developing systems
  • Our investigation: We audit any products in your home that may be of concern and assess their potential impact
  • Solutions: We provide recommendations and safer alternatives that protect health without sacrificing cleanliness or comfort

Auditing household products gives you clarity on what may be harming your environment and empowers you to make healthier choices every day.

Every home and every family is different, which is why all of our assessments are customized. While we cover core areas like mold, water, air quality, chemicals, EMFs, lighting, and more in every investigation, we can also add extra testing based on your unique concerns, such as:

  • Allergen screening
  • Soil testing for environmental contaminants
  • Microplastics in water
  • Bacteria
  • Other specialty analyses by request

If you have a specific concern, our team can design a tailored plan to make sure nothing is overlooked.
