Aston, Delaware County, PA

What does air quality testing reveal in Aston?

Indoor air quality in Aston is shaped by the same things that shape the housing: a township of mostly postwar suburban homes on rolling ground in southwestern Delaware County, where the issues riding the air are usually radon, combustion byproducts, VOCs, and particulates rather than anything you can see. Radon comes first. Southeastern Pennsylvania sits over geology that produces radon, the colorless, odorless radioactive gas that seeps up from the soil and rock and collects in the lowest level of a house, and Aston's split-levels, bi-levels, and ranches put finished living space half below grade where that gas concentrates. Radon is not something a visual inspection or your nose can detect. It takes a measurement. Combustion byproducts are the second concern. A large share of Aston homes were heated with oil and later converted to gas, and gas furnaces, water heaters, and ranges all produce carbon monoxide and other combustion gases that are supposed to vent outside but can spill back into the living space when a flue is oversized, blocked, or pulling poorly, which is exactly the condition many oil-to-gas conversions left behind. VOCs, volatile organic compounds, off-gas from paints, adhesives, new flooring, cabinetry, and stored chemicals, and they build up fast in a tightened-up house with limited fresh-air exchange. Particulates and allergens round it out, from deteriorating original ductwork that has been circulating dust and soot for decades, from dust-mite and pet antigens, and from the fine debris that older forced-air systems redistribute every time they cycle. Aston's mid-century homes were not built with the mechanical ventilation that newer construction includes, so interior air tends to recirculate rather than refresh. Testing the air directly is how you find out what is actually in it, separate from what you can smell or see.

When I test indoor air in Aston, I am sampling for the things this housing stock and this geology produce, and I tailor the panel to the home. For radon, I set a continuous monitor in the lowest livable level, which in an Aston split-level is often a finished lower level where the family actually spends time, and I let it run the full measurement period so the result reflects real conditions rather than a single moment. For combustion safety, I evaluate the gas appliances and their venting and can sample for carbon monoxide and other combustion byproducts, paying particular attention to homes with oil-to-gas conversions where an oversized old flue lets exhaust linger or spill. For VOCs, particulates, and allergens, I collect samples from the living areas and, where it matters, from the supply registers near the air handler so I can tell whether old ductwork is feeding dust into the air. Where mold or moisture is part of the picture, I compare indoor readings against an outdoor baseline taken the same day so the lab can separate what the building is generating from what is simply in the ambient air. Everything goes to a PRO-LAB certified laboratory and results come back in 2-3 business days with a written report I have read and interpreted, and because I do not do remediation, nothing I recommend is shaded by a cleanup I would profit from. The on-site visit usually takes 30 to 45 minutes plus the radon monitor's run time. Folks buying in Brookhaven ask the same questions, and the answers carry over because the housing is so similar. Call 610-348-6728 to schedule.

What air quality risks do Aston's 1950s–1970s homes face?

Homes from the 1940s–1960s pose specific air quality risks from construction materials now known to be hazardous, including asbestos, lead paint, and early fiberglass insulation products.

Asbestos fibers from deteriorating floor tiles, pipe insulation, and duct tape

Lead paint on original windows, trim, and exterior siding

Galvanized ductwork with interior rust and decades of accumulated dust

Poor attic ventilation trapping moisture and supporting mold growth in roof sheathing

What does an indoor air quality test check for?

Bob performs all inspections per InterNACHI Standards of Practice. His air quality testing in Aston follows PRO-LAB protocols calibrated to the specific risks of post-war and mid-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 Aston homes?

Based on 20+ years testing post-war and mid-century homes in Delaware County, these are the issues Bob finds most often:

  • Asbestos in 9x9 floor tiles, pipe insulation, and boiler components
  • Galvanized steel plumbing with internal corrosion reducing water pressure
  • Undersized electrical panels (60-100 amp) unable to support modern loads
  • Poor attic ventilation in Cape Cod designs causing ice dams and moisture damage
  • Original single-pane windows with failed glazing and air infiltration
  • Basement moisture from minimal or absent exterior waterproofing

Common Questions

Air quality testing questions for Aston

Indoor air quality testing in Aston by All Seasons starts at $275 for a standard mold spore and particulate panel. That base price covers a 30-to-45-minute site visit, hands-on sample collection by Bob, PRO-LAB certified laboratory analysis, and a written report with a plain-language explanation of every result. Additional panels for radon, VOCs, combustion byproducts, or allergens are priced individually based on how many samples the property needs. Because All Seasons never performs remediation, every 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 an Aston home looks at mold spore types and counts, fine particulate levels, volatile organic compounds from paints and adhesives, allergens such as dust-mite and pet antigens, and combustion byproducts including carbon monoxide. Radon is tested with a separate continuous monitor placed in the lowest livable level. Given Aston's postwar housing and its oil-to-gas conversion history, Bob pays particular attention to combustion safety on gas appliances and to particulates circulating from aging ductwork. Where moisture is a factor, indoor readings are compared against an outdoor baseline so the report can isolate what the building is generating from what is entering from outside.
The on-site visit in a typical Aston home takes 30 to 45 minutes for sample collection. If radon is part of the order, a continuous monitor runs in the lowest livable level for the full measurement period, usually a couple of days, before it is retrieved. The collected samples go to a PRO-LAB certified laboratory the same day, and results with a written interpretation come back in 2-3 business days. If you are inside a real estate transaction, scheduling early in the inspection period leaves enough lead time to review the findings before any contingency deadline. Call 610-348-6728 to set it up.
Yes, radon testing is worth doing on most Aston homes. Southeastern Pennsylvania sits over geology that produces radon, a colorless, odorless radioactive gas that seeps up from soil and rock and collects in the lowest level of a house. Aston's split-levels, bi-levels, and ranches commonly put finished living space half below grade, which is exactly where radon concentrates and exactly where people spend time. There is no way to know your level without measuring, because radon has no smell or visible sign. Bob places a continuous radon monitor in the lowest livable level and lets it run the full measurement period, so the result reflects real living conditions. If the level is elevated, mitigation is straightforward, and you will have documented data to act on.
They affect it in two ways that I check for. First, combustion safety. Many Aston homes converted from oil heat to gas, and when the conversion left the original chimney flue in place, that flue is often too large for the lower-temperature exhaust of modern gas equipment, which can let combustion byproducts including carbon monoxide linger in the flue or spill back into the living space instead of venting cleanly. Second, particulates. Decades of oil combustion leave a carbon and oil residue coating the interior of old ductwork, and when newer gas equipment moves air through that same ductwork, it disturbs the deposits and pulls them into the circulated supply. Residents often notice a dusty or faintly sooty smell when the heat first cycles in the fall. Sampling supply-register air against a room baseline shows whether the ductwork is contributing.
VOCs, volatile organic compounds, are gases that off-gas from paints, finishes, adhesives, new flooring and cabinetry, cleaning products, and stored chemicals. In a mid-century Aston home that has been tightened up with new windows and added insulation but never given mechanical fresh-air ventilation, VOCs can build up because the air recirculates rather than exchanging with outside. They are a particular concern right after a renovation, a fresh coat of paint, or a flooring or cabinet install, when off-gassing is at its peak. Symptoms people report include headaches, eye and throat irritation, and dizziness that eases when they leave the house. Air quality testing can measure VOC levels so you know whether what you are smelling is a passing nuisance or a level worth ventilating and addressing.
Yes, renovation is one of the clearest reasons to test in Aston, especially in the older housing near the mill villages and along Chester Creek that predates the 1950s suburban boom. Disturbing original plaster, old pipe insulation, pre-1980 building materials, and decades-old ductwork releases particulates and fibers into the air that can linger long after the work is done. New paints, adhesives, flooring, and cabinetry add a VOC load on top of that. Testing after the work and before you fully reoccupy the space gives you an objective read on particulate, fiber, and VOC levels rather than a guess. It is a sensible step any time a project has stirred up the materials in an older home, and it protects everyone who is going to be breathing that air.
It can. When a household member has persistent respiratory issues, allergy-like reactions, or recurring headaches that improve when they are away from the house, the indoor air is a logical thing to check, and testing turns a suspicion into data. In Aston's housing stock the usual suspects are mold spores from a damp below-grade level or crawl space, combustion byproducts from a poorly venting gas appliance, elevated particulates from aging ductwork, VOCs from finishes and stored chemicals, and radon, which causes no acute symptoms but carries a documented long-term health risk. Bob samples for these, sends the samples to a PRO-LAB certified laboratory, and returns a written report in 2-3 business days that tells you what is actually present so you can address the right source instead of guessing.
There is overlap, but they are not the same. Mold testing focuses specifically on mold, sampling the air and, where there is visible growth, surfaces to identify spore types and counts and compare them to an outdoor baseline. Indoor air quality testing is broader. It can include mold, but it also covers radon, combustion byproducts like carbon monoxide, VOCs, particulates, and allergens, the full range of things that affect the air in an Aston home beyond mold alone. If your concern is a damp basement or a musty smell, mold testing may be the right starting point. If you want a fuller picture of what your family is breathing, particularly with the radon and combustion considerations common to Aston's postwar homes, an air quality panel is the broader tool. Bob can help you decide which fits your situation when you call.
