Indoor Air Quality Testing Brewerytown, Philadelphia

Brewerytown, Philadelphia County, PA

What does air quality testing reveal in Brewerytown?

Along the 29th and 31st Street blocks where Brewerytown's dense rowhouse fabric runs toward the Strawberry Mansion border, the air inside a home carries the memory of everything that happened on that land before the current occupant arrived. This is a neighborhood built around industrial production -- the former Schmidt brewery complex anchored the district for generations, and the pre-1920 rowhouses that line Glenwood Avenue and push north toward Cecil B. Moore Avenue were constructed to house the workforce that kept those operations running. That co-location of residential and heavy industrial use, sustained over more than a century, shapes what an air sampler finds inside these buildings today. The Girard Avenue commercial corridor adds a second layer: truck traffic, diesel exhaust, and commercial kitchen ventilation all push particulate matter into the older building stock along the avenue, where original single-pane windows and gaps in the masonry provide little resistance to outdoor air infiltration. South toward Francisville, and east toward Fairmount, the character shifts somewhat -- larger lots near Lemon Hill and Fairmount Park mean better natural ventilation around freestanding structures -- but the rowhouse blocks that form the core of the neighborhood share a common profile: original foundations, original plaster, and a site history that predates modern environmental standards by fifty years or more. New construction on former industrial lots along the former Schmidt brewery site footprint presents its own concerns: what was manufactured or stored on a given parcel determines what may have absorbed into the soil, and from the soil into a crawlspace or basement slab, and from there into the air column that occupants breathe. Understanding that history is the starting point for any serious indoor air quality evaluation in Brewerytown.

Former industrial use creates a different air quality baseline than what you find in a purely residential neighborhood -- and that difference is something I look for specifically when I am working in Brewerytown. Some of the pre-1920 homes I test on the blocks surrounding the former Schmidt brewery site absorbed decades of airborne byproducts from brewery operations: fermentation gases, grain dust, coal combustion particulate from the boiler systems that powered the facility. The original stone and brick foundations and basements in these rowhouses are porous, and residue that settled into those materials over generations does not simply disappear when the industrial activity stops. When I take air samples in these basements today, I am sampling an environment that has been accumulating inputs since the 1880s. New construction on former industrial lots requires a different approach -- rather than looking for what accumulated over time, I want to know what was manufactured or stored on that specific parcel and whether any of it is still present in the soil gas that can migrate through a new foundation. In the majority of 1880s-1920s Brewerytown homes I test, I find three contaminant sources that owners rarely expect: lead paint dust from deteriorating trim, windows, and doors, especially during renovation; aging plaster walls that trap moisture and support hidden mold colonies behind finished surfaces; and coal dust remnants in basements from the original coal heating systems that served these homes before conversion to gas. Those findings are not unique to Brewerytown, but the industrial site history here adds a fourth variable that I take seriously on every job. Clients in the Fairmount area deal with a version of this -- see Fairmount -- but the former industrial footprint in Brewerytown is more concentrated and more recent in its activity.

What air quality risks do Brewerytown's 1880s–1920s homes face?

Pre-1920 homes present unique air quality challenges from over a century of construction materials, renovations, and building practices that predate modern ventilation standards.

What does an indoor air quality test check for?

Bob performs all inspections per InterNACHI Standards of Practice. His air quality testing in Brewerytown follows PRO-LAB protocols calibrated to the specific risks of late 19th and early 20th century construction:

What are common issues in Brewerytown homes?

Based on 20+ years testing late 19th and early 20th century homes in Philadelphia County, these are the issues Bob finds most often:

• Knob-and-tube wiring still energized behind walls and under blown insulation
• Stone foundation moisture intrusion and mortar joint deterioration
• Lead paint on original trim, windows, and exterior surfaces
• Gas pipe conversions from original coal or oil systems with improper venting
• Original clay sewer laterals with root intrusion and bellied sections
• Aging slate or clay tile roofs with deteriorating flashing
