The science

The science behind your Nestwell Score

Nestwell's assessments draw on federal agency data, nearby hazard data, and real lab results to give you a complete picture of what's actually in the air, water and soil in and around your home.

How your score works

Your Home Health Score (0–100) is a weighted composite across three environmental categories: air, water, and soil quality. Each category is scored independently using your property's address data and regional environmental records.

What we measure

Environmental health risk doesn't come from one source. We assess the air, water, weather and environmental hazards in your area to give you a full picture of your home's health.

  • Airthe air you breathe
  • Waterthe water you drink
  • Soilthe ground around your home

Our physical & home environment is a direct determinant of our health, and is immunoregulatory. In a year, we breathe about 6 million times, drink 250 gallons of liquid, and eat almost 2 tons of food, with hundreds of compounds interacting on our skin and immune systems. Small environmental changes make a big difference, especially in early childhood development and for vulnerable adults.

Your Home Insights, kept current

Environmental conditions around your home change daily. Air quality shifts with the weather, smoke drifts in from hundreds of miles away, a drought tightens your regional water supply. Your Nestwell Score captures your baseline; the Insights map keeps you current.

The live map layers real-time and near-real-time data directly over your property, pulled fresh each session. A “Right now” strip distills it to what matters most: current AQI, active alerts, drought class, and nearby fire activity.

From inferred to lab-confirmed

A quiz-only score is a risk estimate, directional and useful, but built on proxies. When you add certified lab results from a Nestwell test kit, your score upgrades from inferred to lab-confirmed: grounded in measurements from your specific home, not regional averages. Lab results can surface issues the regional data couldn't catch.

Frequently asked questions

What’s a home health assessment?

A home health assessment helps you understand how your indoor environment may be affecting your wellbeing. Nestwell evaluates factors like air quality, water quality, moisture, mold risk, soil concerns, property history, and location-specific environmental data. When deeper confirmation is needed, Nestwell can recommend home health testing options so you can move from general risk signals to specific next steps.

Where does the data come from?

Your initial Nestwell Score draws on trusted public data tied to your address — at the neighborhood and ZIP code level. We pull from sources like the EPA, the Environmental Working Group (EWG), and property data providers to build a baseline picture of what’s likely happening in and around your home. To go from area-level data to what’s actually happening inside your home, we partner with SimpleLab for at-home testing kits — lab-grade results specific to your home, not just your neighborhood.

Is Nestwell right for my home?

Yes — whether you live in an apartment, a single-family house, a condo, a townhome, or somewhere in between, Nestwell is designed to meet you where you live. We tailor your report and recommendations to your specific situation — including what’s actually in your control. There are meaningful improvements you can make in any home, and we focus on the ones that fit your space, your lease, and your budget.

How long does it take to get my report?

Your initial Nestwell report is ready in a few minutes — as soon as you finish your intake. You’ll see your Nestwell Score, your risk signal across each category, and your top recommended next steps.
