For the people you love

You can’t protect them from everything. Start with the air they breathe and the water they drink.

Testing identifies potential exposures in the places your family spends the most time, the bedroom, the kitchen, the tap, and gives you practical, prioritized next steps instead of guesswork.

What we test

Here’s what we do in your home.

Water testing, seven-day air monitoring, and gas-cooking NO₂ screening, with exactly what each includes. Laboratory analysis and on-site monitoring are labeled separately, with the sampling location and units for each.

Simplified layout for illustration. Every basic inclusion above applies regardless of your home’s floor plan.

What can go unnoticed.

A home can look immaculate and still have air and water you’ve never measured. Three specific, well-documented concerns, and what measurement adds.

Water being poured into a clear glass, light refracting through it
Laboratory analysisKitchen tap · µg/L

Clear water can still contain lead.

Possible source

New York's supply is treated before it reaches your building, but lead service lines, old solder and brass fixtures inside the building can add lead to the water that sits in your pipes.

What we measure

Laboratory analysis of samples from your kitchen tap, including a first-draw sample, for lead and other common drinking-water contaminants.

What you learn

Your result beside EPA's action level and health goal, with practical steps such as flushing habits or whether a certified filter makes sense.

EPA · Lead in drinking water

On-site screeningStove · bedroom · ppb · µg/m³

Gas cooking can add pollution to your kitchen air.

Possible source

Burning gas releases nitrogen dioxide and fine particles. Without a hood vented outdoors or an open window, those by-products build up in the kitchen and drift into the rest of the home.

What we measure

On-site readings at the stove while it's in use, in homes with a gas stove, alongside seven days of fine-particle monitoring in the bedroom.

What you learn

How much cooking changes your air, how quickly it clears, and whether your current ventilation is keeping up.

EPA · Nitrogen dioxide indoors

On-site monitoringBedroom · index

New materials can release chemicals into your air.

Possible source

Paints, adhesives, new flooring and furnishings off-gas volatile organic compounds, usually most noticeably in the weeks after they arrive.

What we measure

Seven days of total VOC monitoring in the bedroom. The reading shows overall level and pattern; it does not identify individual chemicals.

What you learn

Whether readings are settling, when they peak, and when more ventilation or a specialist chemical analysis would be worthwhile.

Know your next steps.

Every measurement comes with its result and unit, the sampling location, a relevant reference, a plain-language explanation and a recommended next step. No scores, no blanket safe-or-unsafe labels.

Laboratory · Kitchen tap

Detected · below action level

2.1

µg/L

EPA action level 15 µg/L · health goal 0

Lead was detected at a low level. The action level is a regulatory trigger for water systems, not a line between safe and unsafe; EPA's health goal for lead is zero.
Next stepDiscuss flushing habits and whether a certified filter makes sense for your household. Re-test after any plumbing work.

Carbon dioxide (CO₂), bedroom overnight

7-day monitor · Bedroom

Worth attention

1,420

ppm peak

Common ventilation benchmark ≈1,000 ppm

CO₂ builds when a closed room has limited fresh air. It indicates ventilation; it is not a carbon-monoxide reading.
Next stepLeave the bedroom door ajar or crack a window at night, then compare on a later reading.

Nitrogen dioxide (NO₂) at stove during cooking

On-site screening · Stove

Worth attention

88

ppb peak

EPA outdoor 1-hour standard 100 ppb

A short peak during burner use with the hood off. Indoor NO₂ has no federal standard; the outdoor one-hour value is shown for context only.
Next stepUse the range hood or open a window whenever burners are on. Discuss longer-term options on the call.

Your assessment includes a 45-minute conversation to walk through the findings and discuss practical next steps.

How the assessment works

From your first question to your results.

One visit, one week of monitoring, one conversation.

  1. Step 1

    Your visit

    We come to your home, collect the agreed water samples, take on-site readings and set up the bedroom air monitor.

  2. Step 2

    Your monitoring period

    The monitor records your air for seven days while the laboratory analyzes your water. We arrange the equipment return with you in advance.

  3. Step 3

    Your results review

    You receive the written findings, then we walk through them together on your included 45-minute call and discuss next steps.

A new home.
A growing family.
A reason to know.

People book for different reasons. Choose the one closest to yours, if you like, and we’ll carry it into your booking.

Also common: older plumbing, gas cooking, ventilation questions, nearby construction, checking after filtration or other changes.

Any time is a reasonable time to measure.

Visit
One visit: tap samples, on-site readings, monitor set-up.
