Sharon Hill, Delaware County, PA

What does air quality testing reveal in Sharon Hill?

Indoor air quality in Sharon Hill is shaped by the borough's geology and by the age of its housing as much as by anything residents do day to day. The single biggest concern is radon. Southeastern Pennsylvania sits over geology with elevated radon potential, and radon is an odorless, colorless gas that seeps up from the soil through cracks in slabs, stone and block foundation walls, sump pits, and utility penetrations — and it concentrates in the low, enclosed basements that Sharon Hill's 1900s-to-1930s rowhomes and twins were built with. You cannot smell it or see it; the only way to know your level is to measure it. The second concern is combustion byproducts. Many homes here heat with gas appliances vented into older masonry chimneys, and a great many were converted to gas from coal or oil over the decades. When a flue is oversized or deteriorated, or when a water heater or furnace is not venting cleanly, carbon monoxide and other combustion gases can spill back into the living space instead of going up the chimney — a genuine safety issue, not just a comfort one. Third are volatile organic compounds, the off-gassing from paints, adhesives, new flooring, solvents, and finishes, which build up in tight or poorly ventilated rooms. Fourth are particulates and the residue of old systems: decades of soot can coat the interior of ductwork and chimneys in homes converted from coal or oil, and a newer system pushing air through that old ductwork stirs those deposits back into circulation. And fifth is ventilation itself — housing of this era was built with little mechanical exhaust, so bathroom and kitchen moisture, dust, allergens, dust-mite and pet antigens, and everything else generated indoors tends to linger rather than clear. None of these is visible during a normal walk-through, and several of them — radon and carbon monoxide especially — are dangerous precisely because they give no warning. Measuring the air is the only way to know what is actually in it.

When I test indoor air in a Sharon Hill home, I start by matching the test to the house and to what the people living there have noticed. Radon testing uses a calibrated monitor placed in the lowest livable level for the measurement period, which matters in this borough because the low, enclosed basements common to these rowhomes and twins are exactly where radon collects. For combustion concerns I look at how the gas appliances are venting and sample for carbon monoxide and related byproducts, paying particular attention to homes that were converted to gas and vent into an older oversized chimney. For VOCs, particulates, and allergens I collect air samples from the rooms in question and, where it helps, sample the supply air near the heating system to see whether old ductwork is contributing soot and dust to what is being circulated. Every sample goes to a PRO-LAB certified laboratory, results come back in 2-3 business days, and I read the report with you in plain language instead of leaving you to decode raw numbers. Because I do not sell remediation or any product, what I report is just what the air contains. Buyers comparing homes in nearby Glenolden often find the same combination of radon-prone basements and converted heating systems that I see in Sharon Hill. If you are buying, selling, or simply want to know what your family is breathing before the next heating season, call 610-348-6728.

What air quality risks do Sharon Hill's 1900s–1930s homes face?

1920s–1940s homes often have air quality challenges related to aging mechanical systems, plaster dust from deteriorating walls, and early insulation materials that may contain hazardous fibers.

Oil furnace residue and soot in ductwork from original or converted heating systems

Plaster dust and deteriorating horsehair lath releasing particulates into living spaces

Early vermiculite insulation that may contain tremolite asbestos

Inadequate bathroom ventilation in homes predating modern exhaust fan requirements

What does an indoor air quality test check for?

Bob performs all inspections per InterNACHI Standards of Practice. His air quality testing in Sharon Hill follows PRO-LAB protocols calibrated to the specific risks of early to mid-20th century construction:

Mold Spore Analysis

Air samples capture mold spores floating in your indoor air. Lab analysis identifies specific species and their concentration levels compared to outdoor baseline readings.

Indoor vs. Outdoor Comparison

Bob collects both indoor and outdoor baseline samples. The comparison reveals whether your home's air quality is worse than the surrounding environment — the clearest indicator of a problem.

PRO-LAB Certified Lab Results

All samples go to a PRO-LAB certified laboratory. Results return in 2-3 business days with a detailed written report. Bob walks you through exactly what the numbers mean — no jargon, no scare tactics.

What are common issues in Sharon Hill homes?

Based on 20+ years testing early to mid-20th century homes in Delaware 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

Common Questions

Air quality testing questions for Sharon Hill

Indoor air quality testing in Sharon Hill by All Seasons starts at $275 for a standard panel, which covers a site visit, hands-on sample collection by Bob, PRO-LAB certified laboratory analysis, and a written report explaining every result in plain language. Additional panels — radon, VOCs, combustion byproducts, or allergens — are priced individually based on how many samples the property needs. Because All Seasons never performs remediation, the price reflects testing only, with no incentive to recommend work that is not warranted. Call 610-348-6728 for a quote.
A standard test in a Sharon Hill home can check radon, combustion byproducts such as carbon monoxide from gas appliances, volatile organic compounds from paints and finishes, fine particulates, mold spore types and counts, and allergens including dust-mite and pet antigens. Given the borough's geology and the age of the housing, Bob pays particular attention to radon in the low basements these homes were built with, to combustion venting in homes converted to gas, and to particulate levels near older ductwork. Where it helps, indoor readings are compared to an outdoor baseline so the report isolates what the building is generating from what is coming in from outside.
The on-site visit for most air sampling in a Sharon Hill home takes roughly 30 to 45 minutes, and samples go to the PRO-LAB certified laboratory the same day, with results back in 2-3 business days. Radon testing is different — it requires a calibrated monitor to sit in the lowest livable level for a set measurement period before it can be read. Bob's written report comes with the results either way, so you are not left interpreting raw numbers. If you are inside a real estate timeline, schedule early so findings are in hand before any deadline.
Yes. Southeastern Pennsylvania sits over geology with elevated radon potential, and Sharon Hill is no exception. Radon is a colorless, odorless gas that rises from the soil and enters homes through cracks in slabs, stone and block foundation walls, sump pits, and utility penetrations, then concentrates in enclosed basements — exactly the kind of low basement Sharon Hill's older rowhomes and twins were built with. Because you cannot see or smell it, testing is the only way to know your level. If it comes back elevated, the fix is a straightforward mitigation system, but you need the measurement first. Call 610-348-6728 to arrange a radon test.
It can, in two ways. First, venting: many Sharon Hill homes were converted to gas from coal or oil and vent into an older masonry chimney that was sized for the original fuel. An oversized or deteriorated flue can let carbon monoxide and other combustion gases spill back into the living space instead of leaving through the chimney. Second, residue: decades of coal or oil combustion leave soot coating the interior of old ductwork and flues, and a newer gas system moving air through that ductwork can stir those deposits back into circulation. Testing the combustion venting and sampling the circulated air identifies whether either is a real problem.
VOCs — volatile organic compounds — are gases that off-gas from paints, adhesives, new flooring and carpet, solvents, cleaning products, and finishes. They are worth attention in any home that has had recent renovation or new materials installed, and they matter more in the older Sharon Hill housing stock because these homes were built with little mechanical ventilation, so VOCs that off-gas indoors tend to linger rather than clear out. If your household has noticed headaches, irritation, or strong odors after painting or remodeling, a VOC panel measures what is actually in the air. Bob can include VOC sampling alongside a standard air quality test.
Housing built in Sharon Hill from the 1900s through the 1930s was constructed before mechanical ventilation was standard. Bathrooms and kitchens often had no exhaust fans, so moisture, odors, and particulates generated indoors had nowhere to go but into the rooms and wall cavities. Combine that with the enclosed basements where radon and combustion gases concentrate, the soot-lined ductwork in homes converted from coal or oil, and the natural tightening that happens when owners add insulation and replacement windows over the years, and you get homes where indoor air does not clear on its own. That is why measuring the air, rather than assuming, is the reliable approach.
It is a sensible step, especially for the older housing that makes up most of the borough. The same features that define these homes — enclosed basements, masonry chimneys often serving converted gas appliances, original ductwork, and minimal ventilation — are the features that correlate with radon accumulation, combustion-venting issues, and elevated particulates. A buyer moving in with children or anyone with respiratory sensitivity has a real interest in knowing what the air holds before the first winter heating season. The cost is modest against the transaction, and the written report gives you documentation to act on, whether that means requesting a mitigation credit or simply proceeding with confidence. Call 610-348-6728.
It often can. Headaches, persistent congestion or allergy-like reactions, or symptoms that ease when a person is away from the house and return when they come back are all reasons to test. Air quality testing measures the things that cause those patterns but cannot be seen — radon, carbon monoxide and other combustion byproducts, VOCs, elevated particulates, and airborne mold spores or allergens. Bob samples the relevant rooms and the mechanical spaces, compares against an outdoor baseline where it helps, and the lab report identifies what is actually elevated. That turns a vague concern into specific, documented information you can act on. Call 610-348-6728 to talk it through.
