Radon Mitigation in Fleetwood
High radon risk from Precambrian granulite and gneiss of the Reading Prong's core geological complex. Fleetwood sits directly on some of the oldest and most uranium-enriched rock in southeastern Pennsylvania — high-grade metamorphic basement that formed over a billion years ago. The granulite-gneiss complex here has higher uranium concentrations than the surrounding schist, making this section of the Reading Prong particularly productive for radon.
High Radon Risk Area
Fleetwood sits in EPA Zone 1 — testing is recommended for every home regardless of age or foundation type.
Local Geology & Risk Factors
Fleetwood is located in an area with Reading Prong / Precambrian Granulite-Gneiss Complex geology, which contributes to elevated radon levels. The Pennsylvania DEP identifies this region as having significant radon potential due to uranium-bearing rock formations.
Testing is essential because radon levels can vary significantly between neighboring homes based on construction, soil permeability, and ventilation.

Quick Facts
- Median home value: $216,700 · Median year built: 1961
- Population: 4,045
- Foundation types: Basement (predominant in borough and rural homes); Stone foundation (farmhouse conversions); Crawlspace
Berks County Context
Fleetwood is a municipality of Berks County, EPA Zone 1. Zone designation is assigned at the county level, so Fleetwood inherits its classification; countywide aggregate figures live on the county page.

Radon Mitigation Cost in Fleetwood
Active sub-slab depressurization (ASD) systems in Fleetwood typically cost $1,000–$2,600. Standard basement installs on modern poured concrete fall at the lower end; historic foundations, block-wall depressurization, multi-point suction, and crawlspace encapsulation push costs higher.

Certification & Compliance
All Pennsylvania radon testing and mitigation professionals must hold active PA DEP certification. Ask any contractor for their certification number and verify it before signing.
Pennsylvania's Real Estate Seller Disclosure Law (68 Pa.C.S. §§ 7301–7315) requires sellers to disclose known material defects to buyers under § 7303; the mandated disclosure form records radon under § 7304(b)(14). Sellers who have never tested are not compelled to test — § 7308 imposes no affirmative duty to investigate — but pre-listing testing is standard practice across most PA markets.
Under 25 Pa. Code § 240 — the Pennsylvania chapter governing radon certification — every radon service provider working in the Commonwealth must hold current DEP certification. Verify the contractor's status via the DEP Radon Services Directory before hiring.

Frequently Asked Questions
Why does Fleetwood have some of the highest radon levels in Berks County?
Fleetwood sits on the Reading Prong's core geological complex — Precambrian granulite and gneiss that are among the oldest rocks in Pennsylvania (over 1 billion years old). These high-grade metamorphic rocks were formed under extreme heat and pressure that concentrated trace uranium within their mineral structure. The granulite-gneiss complex in this section of the Reading Prong has measurably higher uranium content than the surrounding schist, making Fleetwood one of the most radon-productive areas in southeastern PA.
Is radon risk uniform across Fleetwood or does it vary by neighborhood?
Radon levels vary across Fleetwood because the Reading Prong's uranium content depends on the specific mineral composition of local outcrops. Areas where granulite is closest to the surface tend to have the highest readings. Weathered soil thickness, foundation type, and home ventilation also affect indoor concentrations. Neighboring homes can have significantly different radon levels. Individual home testing is essential regardless of neighborhood averages.
What does radon mitigation cost in Fleetwood?
Fleetwood area radon mitigation typically costs $1,000–$2,600. Higher initial radon concentrations common in the Reading Prong core area may require more powerful fan systems. Converted farmhouses with stone foundations cost more than standard construction. Request quotes from DEP-certified Berks County contractors.
What's the average radon level in Fleetwood?
Fleetwood's DEP-recorded basement average is 11.48 pCi/L across 2,262 tests. The EPA action level for mitigation is 4.0 pCi/L, so a sizable share of Fleetwood homes exceed the threshold. The highest single result in the local dataset is 1204.7 pCi/L; this unusually high reading may reflect a source data anomaly or a single-home outlier — individual home results vary widely.
Do homes in Fleetwood need to be tested for radon?
Berks County is EPA Zone 1 — the highest radon-potential classification — so every home in Fleetwood should be tested regardless of age, foundation type, or neighborhood. Short-term charcoal or continuous monitor tests take 48–96 hours and cost $15–$50; long-term alpha-track tests run 90 days and better represent annual averages. If the result meets or exceeds 4.0 pCi/L, mitigation by a DEP-certified professional is recommended.
How much does radon mitigation cost in Fleetwood?
Active sub-slab depressurization (ASD) systems in the Fleetwood area typically cost $1,000–$2,600. Standard basement installations on modern poured-concrete foundations fall at the lower end; historic foundations, block-wall depressurization, multi-point suction, and crawlspace encapsulation push costs toward the upper end. All work must be performed by a DEP-certified mitigation professional under 25 Pa. Code § 240.
Is radon disclosure required when selling a home in Fleetwood?
Pennsylvania's Real Estate Seller Disclosure Law (68 Pa.C.S. §§ 7301–7315) requires residential sellers to disclose known material defects to buyers (§ 7303). The state-mandated disclosure form covers 'presence of hazardous substances' at § 7304(b)(14) — where any known elevated radon test result or existing mitigation system is recorded. Sellers who have never tested are not required to test: § 7308 imposes no affirmative duty to investigate. In Fleetwood, the practical reality is that most buyers request radon testing during the inspection contingency period. Sellers who test and mitigate before listing eliminate the most common contract contingency and preserve negotiating position.
Which ZIP codes does the Fleetwood radon data cover?
The Fleetwood radon dataset on this page covers ZIP code 19522. These are the ZCTAs assigned to Fleetwood in the Census 2020 ZCTA-to-Place relationship file and used for the PA DEP RadonZip Tool aggregation. Neighboring ZIP codes belong to adjacent municipalities and appear on their own PA Radon Hub pages.
Are Fleetwood Area School District buildings subject to SB 760?
Berks County is in EPA Zone 1 and is served by 19 school districts, including Fleetwood Area School District. Pennsylvania Senate Bill 760, if enacted as drafted, would apply to all public school buildings in Berks County regardless of which district operates them. The bill remains in committee. Buildings in Zone 1 counties like Berks County would be highest priority under the proposed framework. If SB 760 is enacted, mitigation timelines, thresholds, and qualifying buildings would be set by the final bill text and any subsequent DEP implementing regulations. PA Radon Hub tracks this legislation; specific deadlines remain pending.
