How does mold testing work in Eddington?

Last updated June 21, 2026

Eddington is a riverfront community in Bensalem Township, Lower Bucks County, set along the Delaware River corridor between Cornwells Heights to the south and Croydon to the north. The neighborhood runs off US-13 Bristol Pike toward the river, and SEPTA's Trenton regional rail line passes through with the Eddington station serving commuters into Philadelphia and out toward Trenton. The land here sits low and close to the water, and that single fact shapes almost everything about how moisture behaves in the housing stock. Much of Eddington was built across a long stretch of the twentieth century: older early-1900s frame and masonry homes near the original rail and pike corridors, followed by waves of postwar tract construction through the 1940s, 1950s, and into the 1960s as Lower Bucks filled in around the Levittown building boom. That mix means you find genuinely different foundation types within a few blocks of each other. The early homes typically have stone, fieldstone, or hollow-core concrete block foundations that wick groundwater through the masonry, while the postwar tract houses often sit on slab-on-grade or shallow crawlspace construction with no full basement at all, a Levittown-era pattern common throughout Lower Bucks. Both create moisture problems, just by different paths. The river proximity is the dominant driver. Eddington lies within the Delaware River floodplain, and the seasonal water table here rises measurably after sustained rain and during spring melt, pushing groundwater against foundation walls and up under slabs through hydrostatic pressure. Homes on the lower-lying blocks closer to the river feel this most. Beyond the river itself, the surrounding drainage includes the Poquessing Creek, which forms the Philadelphia border just south near Andalusia and Cornwells Heights, and the broader low-gradient terrain that drains slowly toward the Delaware. Add the construction-era details typical of this stock — plaster-over-lath walls in the older homes, minimal original bathroom ventilation, clay sewer laterals running beneath mature street trees that accumulate root intrusion and bellied sections, and oil-to-gas furnace conversions that left oversized chimney flues prone to condensation — and you have a community where moisture has many quiet routes into the building. Crawlspaces under the postwar homes are a particular concern, because an unsealed dirt or vented crawlspace near a high water table stays damp year-round and feeds spore growth into the floor structure above without anyone ever seeing it.

I have tested homes throughout Eddington and the river blocks of Bensalem Township for years, and the patterns repeat. On the postwar slab and crawlspace homes, the problem is rarely a dramatic flood. It is the slow, steady moisture load from a high water table sitting under a slab or seeping into a vented crawlspace, raising humidity in the floor system and the lower living areas without ever producing standing water a homeowner would notice. I take moisture readings on foundation walls and slab edges, and when there is a crawlspace I go into it, because that is where the real story usually is in this housing stock. On the older early-1900s frame and masonry homes near the pike and the rail line, the concern shifts to hollow-core block and stone foundations that absorb river-corridor groundwater, plaster walls that hold moisture for months with no surface staining, and clay sewer laterals with root intrusion that backs up and saturates sub-slab soil. I take an outdoor control sample on every job so the laboratory comparison reflects genuine indoor elevation rather than whatever spore count happens to be in the ambient air that day, and samples go to a PRO-LAB certified laboratory with results back in 2-3 business days. I review every report myself and explain it to you in plain language rather than handing over a table of numbers. I do not perform remediation, so nothing I find carries a financial conflict of interest. I serve Eddington alongside neighboring river communities including Cornwells Heights.

Why are Eddington's 1900s–1960s homes at risk for mold?

Homes from the 1920s–1940s combine aging infrastructure with building practices that create persistent moisture pathways — clay sewer laterals, minimal foundation waterproofing, and plaster walls that mask moisture damage.

How does Bob test for mold in Eddington?

Bob follows a systematic approach calibrated to the specific risks of early to mid-20th century construction in Bucks County. All sampling protocols follow EPA mold testing guidelines:

What are common issues in Eddington homes?

Based on 20+ years testing early to mid-20th century homes in Bucks County, these are the issues Bob finds most often:

• Clay sewer laterals with tree root intrusion and bellied sections
• Layered electrical upgrades with code violations at old/new connections
• Oil-to-gas furnace conversions with improper chimney liner sizing
• Original slate or clay tile roofs reaching end of useful life
• Plaster-over-lath moisture damage hidden behind intact-looking walls
• Inadequate insulation and single-pane windows driving high energy costs
