Testing options

SHORT-TERM

48-hour test

A monitor placed in the lowest lived-in level of your home for about two days. The standard first look, and what most homeowners start with.

REAL ESTATE

Transaction testing

Buying or selling in Waterbury? Closed-house-condition testing on your closing timeline, with documentation both sides can rely on.

POST-MITIGATION

Verification retest

Already have a system? A retest confirms it's still holding your levels down — recommended every two years by the EPA.

How the test actually works

A short-term test measures your indoor air under "closed-house conditions": windows shut, exterior doors used only for normal coming and going, starting 12 hours before the test and continuing through the full 48. The device sits in the lowest level of the home you regularly use — a finished basement if you spend time there, otherwise the first floor — away from drafts, vents, exterior walls, and humidity sources like bathrooms.

Those conditions aren't a formality. Radon readings swing with ventilation, weather, and even barometric pressure, so the protocol exists to give you a stable, comparable number — the same standard used in real estate transactions nationwide. Skip the closed-house rules and you get a number that looks reassuring and means nothing.

Results are reported in picocuries per liter (pCi/L) with a clear interpretation: what your number means, and what — if anything — to do next. For real estate deals, documentation is written so both sides of the transaction and their agents can rely on it.

Getting a valid result

Closed-house conditions from 12 hours before the test
Device placed in the lowest lived-in level
Away from drafts, vents, sump pits, and high humidity
Heating/AC run normally — they're part of real conditions
No whole-house fans or window units during the test

On a closing deadline?

Say so when you call. The 48-hour clock plus lab turnaround fits inside most inspection windows when it's scheduled promptly.

When to test

You've never tested — most Waterbury homes haven't
You're buying or selling a home
You're finishing a basement or moving a bedroom downstairs
Your last test was more than two years ago
A neighbor's home tested high — levels vary house to house

Winter is when radon runs highest: closed windows and the "stack effect" pull more soil gas indoors. A high winter reading is your home's true worst case.

Reading your result

< 2.0 pCi/L	Good. Retest every two years or after major renovations.
2.0–3.9 pCi/L	Elevated. EPA suggests considering mitigation.
≥ 4.0 pCi/L	At or above the EPA action level. Fix it — mitigation reliably brings it down.
