Designed to understand your whole house
Our Nestwell Starter Bundle. Mold and lead can be found all around your house, and a single swab answers for a single square foot. Sampling four separate places for each is what turns a handful of readings into a picture of the house you actually live in.
Accredited labs, regulatory methods
Every sample is analyzed by an accredited environmental lab with the same methods regulatory testing uses.
Numbers with regulatory context
Results come back as a measured value next to the standard it is judged against, not just a "detected".
One box, no home visit
Everything arrives at once and we tell you both where and how to sample, no outside home inspection needed.
The tests inside
Understand what we are looking for within your home. Open any one to see exactly what it measures.
53 measurementsDrinking Water Test: Level 1 + Bacteria
The broad first look at your drinking water: the metals and minerals it carries, the shape of the water itself, and whether bacteria are getting in.

1 measurementsLead Dust Surface Wipe Test
Whether lead dust is settling on the surfaces in your home — the form of lead that children actually meet, on floors and sills.

25 measurementsVOC Air Exposure Test
What you are actually breathing indoors: the solvents, fuel compounds and off-gassing chemicals that accumulate in a closed-up house.

Identification of the mould you can see, species by species, from a tape lift off the growth itself.

Your Health
Your results, mapped to your body
These results also feed Your Health, where we add them to every other kit you test and show which organs the contaminants found are linked to, how close each is to its safe level, and an estimate of your added lifetime cancer risk.
Built on the EPA’s risk assessment method. It describes exposure in your home, not your health, and is not a diagnosis.

How collection works
Your home’s journey tobetter health
Collect
Take a quick sample from your kitchen tap, swab damp spots that look like they may have mold and wipe the dusty areas around your home. No tools, and no unstable samples that must be sent back the same day.
Mail
Everything goes back in the same box with the prepaid return label. No appointment, nobody in your house, and easy to send back when convenient for you.
Read
Results land in your Nestwell dashboard as they clear the lab, each scored against the standard that applies to it.
Where you can test
Contaminants do not spread evenly through a house, so one sample can come back clean twenty feet from a real problem. These are the places this kit is made to test, and what each one tells you.

- Mold
A number is only useful next to its limit.
At Nestwell, we provide science backed ranges for all the exposures in your home, allowing for personalized suggestions of in home remediation.
Accredited labs only
Samples are analysed by accredited environmental laboratories using the analytical methods used for regulatory compliance work: the same reading a professional consultant would order.
Each result has a standard
A number on its own is not an answer. The EPA action level for lead in water is 15 ppb; the CDC states there is no safe level of lead exposure for children. Each finding is shown against the limit that applies to it.
Where there is no limit, we say so
The EPA sets no numeric limit for mold, and moisture control is the real remedy. Mold results are reported as what is growing and at what relative level, never as just a pass or a fail.
