How does mold testing work in Marlton?

Route 70 and Route 73 slice through Evesham Township at a wide angle, and where they nearly meet, the Promenade at Sagemore anchors a retail corridor that gives way within a few blocks to the split-level and colonial subdivisions that define Marlton's residential character. Head down Elmwood Road or Cropwell Road and the pattern repeats block after block: ranch and split-level homes from the early 1970s, larger center-hall colonials from the 1980s, and denser cul-de-sac developments pushing out toward Voorhees and Cherry Hill by the late 1990s and 2000s. Evesham Township sits on flat, clay-heavy ground, and that terrain does not drain the way builders in this era assumed it would. In neighborhoods built around Kings Grant and along the Stokes Road corridor, finished basements and below-grade family rooms became standard features almost as soon as split-level and bi-level designs took hold, and that is exactly where Marlton's mold risk concentrates today. A house built in 1978 was not built with a vapor barrier behind its basement walls. A split-level built in 1985 has a grade-level transition where water finds its way in during heavy rain. Fifty years on, those original construction choices are still driving the moisture problems Bob finds inside Marlton homes, whether the buyer is closing on a resale near the Promenade or a family has lived in a Kings Grant colonial for two decades without knowing what is behind the paneling.

In most 1970s-2000s Marlton homes Bob tests, he looks for three mold-risk conditions that owners miss. First, below-grade family rooms with carpet laid directly over a concrete slab -- common in split-levels and bi-levels from this era -- trap moisture rising through the slab and turn the carpet padding into a mold reservoir long before anyone notices a smell, especially in homes where the lower-level family room doubles as a playroom or home office with the carpet never pulled up for inspection. Second, the grade-level transitions built into split-level designs themselves: where the lower level meets the yard, water intrudes at the sill and framing during heavy rain, and in a township with clay soil and flat lots like Evesham, that water has nowhere to go but toward the house, so the same low spot gets wet storm after storm until the framing behind the siding starts to hold moisture permanently. Third, insulation installed directly against foundation walls without any vapor barrier -- standard practice through the 1980s -- holds condensation against the wood framing and creates a slow, hidden mold problem that only shows up once drywall or paneling is removed for a renovation or a pre-sale repair. Bob sees the same three patterns in Mount Laurel homes of the same vintage, since both townships built out on similar timelines with similar site conditions and similar clay-based soil. If you smell something musty in a Marlton home or see discoloration near the foundation or HVAC, don't guess -- call Bob at 610-348-6728 for a professional mold test.

Why are Marlton's 1970s–2000s homes at risk for mold?

The split-level and bi-level designs popular from the 1960s–1980s create specific mold risks, particularly in below-grade family rooms, attached garages, and areas where early insulation traps moisture against foundation walls.

How does Bob test for mold in Marlton?

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

What are common issues in Marlton homes?

Based on 20+ years testing late mid-century and early modern homes in Burlington County, these are the issues Bob finds most often:

• Aluminum wiring at outlets and switches creating fire risk at connection points
• Polybutylene plumbing (gray plastic pipe) prone to sudden catastrophic failure
• Federal Pacific or Zinsco electrical panels with breakers that fail to trip
• Below-grade family room moisture from carpet-over-concrete installations
• Undersized HVAC ductwork causing poor airflow and humidity problems
• Inadequate insulation by modern energy standards
