What does a home inspection in Northern Liberties include?

A home inspection in Northern Liberties, Philadelphia, PA is a top-to-bottom evaluation of a single property -- foundation, structure, roof, electrical, plumbing, HVAC, and exterior envelope -- performed in person by Bob against ASHI and InterNACHI standards, with a full photo-documented digital report delivered inside 24 hours.

Few Philadelphia neighborhoods carry as much physical tension as Northern Liberties -- where an 1890s brick rowhouse on Bodine Street sits directly across from a glass-and-steel loft conversion, and the ghost of the Schmidt brewery still anchors the neighborhood's industrial identity even as the Piazza at Schmidt's draws weekend crowds to open-air markets and outdoor concerts. The 2nd Street corridor, running north from Old City through the heart of the neighborhood, functions as both a commercial spine and a living timeline of the city's growth: ground-floor restaurants occupy storefronts that once housed butchers and hardware merchants, while the upper floors retain their original pine floors, plaster walls, and single-wythe brick facades. North of Spring Garden Street, the Liberties Walk townhome development and the newer construction along Germantown Avenue represent a different era entirely -- sealed-envelope construction built on former industrial parcels, with modern mechanicals and entirely different failure modes than their century-old neighbors. The American Street corridor marks the neighborhood's western edge, where warehouses have been carved into condos and the loading dock doors are now picture windows. SEPTA's Market-Frankford Line at 2nd Street and the nearby Girard Avenue bus routes connect residents to Center City in minutes, which has made this area one of the most sought-after zip codes in the region. Callowhill presses in from the south, and the neighborhood bleeds eastward toward Fishtown along Girard Avenue with little physical boundary beyond a change in scale. At street level, you can read the neighborhood's full arc in a single block: original pre-1920 rowhouses with corbeled brick cornices and cast-iron window lintels standing directly beside 2000s-era construction with fiber-cement siding and rooftop decks.

What Bob notices first about Northern Liberties is that the same block can require two completely different inspection frameworks -- the pre-1920 rowhouse and the 2005 loft conversion share an address but almost nothing else in terms of how they were built or what tends to go wrong. On the majority of 1880s-1930s Northern Liberties homes Bob inspects, he actively looks for three issues that appear again and again: energized knob-and-tube wiring that has been buried under blown-in insulation added during a later renovation -- a fire hazard that is invisible without thermal imaging and knowledge of where to probe; stone and rubble foundation walls where the original lime mortar has softened or washed out over a century of groundwater exposure, leaving stones that shift under load and allow moisture to track into finished basements; and original clay sewer laterals that have been in the ground since the late 1800s, now bellied, root-infiltrated, or partially collapsed beneath alley slabs where no one has looked in decades. On the loft conversions and new construction side, Bob shifts his attention to commercial-grade electrical panels retooled for residential loads, altered fire suppression systems that may not meet current residential code, and flat roof assemblies on 2000s-era construction that are approaching or past their designed lifespan. Bob also inspects throughout Fishtown, where buyers face many of the same pre-1920 rowhouse conditions just across Girard Avenue. Bob encourages every client to attend the inspection in person -- he walks you through every finding in real time, explains what matters and what is cosmetic, and answers every question before you are asked to sign anything.

What does Bob check during a Northern Liberties home inspection?

Bob approaches every Northern Liberties inspection per ASHI and InterNACHI Standards of Practice. With 1880s–1930s housing stock dominant in Northern Liberties, he focuses on the era-specific concerns that affect late 19th and early 20th century construction in Philadelphia County.

Stone & Rubble Foundations

Pre-1920 homes commonly have stone or rubble foundations with lime mortar joints that deteriorate over a century of exposure. Bob checks for shifting stones, mortar erosion, water seepage pathways, and structural settlement that can indicate foundation movement requiring professional stabilization.

Knob-and-Tube Wiring & Gas Pipe Conversions

Original knob-and-tube wiring is one of the most critical findings in pre-1920 homes β€” especially when insulation has been blown over active K&T, creating a fire hazard. Bob also evaluates gas pipe conversions from original coal or oil systems, checking for proper sizing, venting, and code compliance.

Original Slate Roofs & Historic Exteriors

Many pre-1920 homes retain original slate or clay tile roofs that, while durable, require specialized maintenance. Bob inspects for cracked or missing slates, deteriorating flashing, and aging copper gutters β€” plus original wood siding, decorative trim, and masonry that may show a century of weathering.

Lead Paint, Plaster Walls & Coal Chute Remnants

Original plaster-and-lath walls, lead paint on trim and windows, and sealed coal chute openings are hallmarks of pre-1920 construction. Bob documents these conditions and evaluates whether past renovations addressed or inadvertently worsened historical hazards.

What are common issues in Northern Liberties homes?

Based on 20+ years inspecting late 19th and early 20th century homes in Philadelphia County, these are the issues Bob finds most often in Northern Liberties's 1880s–1930s housing stock:

  • 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

What are common home inspection questions in Northern Liberties?

Questions buyers and sellers in Northern Liberties ask us most often β€” answered directly.

Inspections start at $375. The exact price depends on the property -- square footage, age, and type (single-family rowhouse, condo unit, or loft conversion) all factor in. Call Bob at 610-348-6728 for a per-property quote before you book.
Bob evaluates the full structure and all major systems: foundation and framing (critical for the rubble-stone foundations common in pre-1920 rowhouses), roof covering and drainage, electrical panel and visible wiring (including knob-and-tube identification), plumbing supply and drain lines, HVAC equipment, interior finishes, windows, doors, and the exterior envelope. For loft conversions, he pays particular attention to commercial-grade systems that were adapted for residential use -- electrical panels, HVAC retrofits, and any altered fire suppression equipment. Everything is documented with photos in a full digital report delivered within 24 hours.
Plan for 2 to 3 hours for a typical Northern Liberties rowhouse or condo unit. Larger loft conversions or multi-story buildings may run a bit longer. Bob strongly encourages buyers to attend -- walking the property with him is the fastest way to understand which findings matter, which are normal aging, and what questions to bring to negotiations.
Bob Klebanoff performs every inspection himself. There are no rotating technicians -- when you book with All Seasons, you get Bob. He delivers every finding in plain-language, flags immediate safety concerns the moment he identifies them, and gives you the information you need to negotiate, accept, or walk away from a deal. Nothing gets buried in jargon. Bob has 20-plus years of experience and holds both InterNACHI and ASHI certifications.
Knob-and-tube wiring is the most common critical finding Bob encounters in Northern Liberties rowhouses built before 1920. The wiring itself was the standard of its era, but two things have made it dangerous over time: the original rubber insulation has dried and cracked, and many owners or contractors have blown insulation over active K&T circuits during energy upgrades -- surrounding the conductors with material that traps heat and creates a fire risk. Insurance companies often refuse to write policies on homes with active K&T, and lenders can require full rewiring before closing. Bob identifies K&T at panels, in attics, and through accessible wall cavities, and documents whether it appears active or has been properly decommissioned.
Yes -- the original clay sewer laterals serving most pre-1920 Northern Liberties rowhouses have been in the ground for over a century. Clay pipe joints loosen over time, allowing tree roots to infiltrate, and the pipe sections can belly or collapse under decades of soil movement and street-level loading. Bob recommends a sewer scope (a camera run through the lateral to the city main) as a companion to the standard home inspection on any pre-1920 property. A failed lateral is a several-thousand-dollar repair and is not visible without the camera -- it will not show up in a standard inspection, which evaluates drain function but cannot see underground.
The Schmidt brewery site and the surrounding industrial parcels that have been converted to residential use over the past two decades present a distinct set of inspection considerations. These buildings were designed for commercial loads -- heavier electrical services, industrial plumbing, flat or low-slope roof assemblies, and HVAC systems scaled for open warehouse floors rather than residential units. Conversions that happened in the early 2000s are now 20-plus years old, meaning those modified mechanical systems are approaching replacement age. Bob evaluates whether the commercial-origin systems were properly adapted for residential occupancy, checks for any altered fire suppression or standpipe systems that may not meet current residential code, and assesses the condition of flat roof assemblies that have limited remaining service life.
Yes -- L&I (Philadelphia Licenses and Inspections) performs code-compliance reviews tied to permits, not buyer-protection inspections. An L&I inspection confirms that permitted work met the code requirements at the time of the permit; it does not evaluate the full condition of the property, identify latent defects in unpermitted areas, or document deferred maintenance. Bob's inspection is conducted from the buyer's perspective, covering the entire structure and all systems regardless of permit history -- including conditions that predate any recent renovation and would never appear in an L&I record.
Condo inspections cover the interior of the unit -- all systems and components within the four walls -- plus any exclusive-use exterior elements such as a private roof deck, balcony, or parking space. Bob documents the condition of in-unit electrical, plumbing, HVAC, windows, and finishes, and flags any visible evidence of water intrusion from the building envelope or shared systems above. For Northern Liberties factory conversions with shared mechanical rooms or central HVAC, Bob notes what is shared versus individual and identifies what the HOA is responsible for versus the unit owner. He recommends buyers also request HOA meeting minutes and reserve fund disclosures, which can reveal known building-wide issues the inspection cannot directly observe.
