Goldsboro is a borough in York County with about 981 residents and 430 homes, median year built 1979. It sits on the Susquehanna next to Newberry Township.

What the PA DEP test records show for Goldsboro

ZIP 17319 covers essentially all of Goldsboro, so these numbers are about as local as public radon data gets.

Look past the median to the high end. One test in 16 here came in at 20 pCi/L or more, five times the action level, and the highest reading on record is 343 pCi/L. Neighboring houses can differ by a factor of ten, so none of this tells you what your house is. It tells you the odds are high enough that a $15 to $30 test kit is worth buying.

Tests people chose to run, not a random survey. Details on the York County radon levels page.

Basement readings versus first-floor readings

In ZIP 17319, basement tests have a median of 3.4 pCi/L, while tests taken on the first floor have a median of 2.1 pCi/L (254 first-floor tests). The gap is smaller than in most of the county, which means readings upstairs here are not much of a relief from the basement number.

Radon results by decade in ZIP 17319

The share peaked in the 2000s at 46.8% and sits at 35.4% for tests since 2020. A drop that size is mostly about who is testing, not the ground. More recent tests come from home sales and from retests after a system went in, and both pull the share down. The rock under Goldsboro has not changed. 413 tests have been logged in 17319 since 2020, so people here are still testing.

Housing in Goldsboro and what it means for a system

Census Bureau, American Community Survey 2020 to 2024:

36.3% of the homes in Goldsboro were built before 1940, against 18.3% county-wide. Houses that old usually sit on stone or early block foundations with no vapor barrier and plenty of joints, which gives soil gas more ways in. They are still very fixable. The installer just spends more time sealing, and sometimes needs a second suction point, which is why these jobs tend to land toward the upper end of the cost range.

About 22.1% of homes here are attached: rowhomes, twins and townhouses. A shared wall does not stop radon, and neither does a neighbor's system, so each unit needs its own test. The tricky part is pipe routing, since there is often no side yard to run the vent up. Our rowhome radon guide covers how installers handle it.

Cost-wise, expect older houses in Goldsboro to land in the $1,200 to $2,500 part of the range once sealing and a possible second suction point are counted. Newer houses are usually the standard $800 to $1,500 job. Full ranges on the cost page.
