What does a home inspection in Darby Township include?

Last updated June 21, 2026

A home inspection in Darby Township, Delaware County 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 InterNACHI standards, with a full photo-documented report delivered inside 24 hours.

Darby Township is a split municipality in the low southeastern corner of Delaware County, bordered by Sharon Hill, Folcroft, Glenolden, Collingdale, Aldan, Upper Darby, and the Philadelphia city line, with Darby Creek, Cobbs Creek, and Muckinipattis Creek defining its edges and draining the township toward the Delaware River. The residential heart is the Briarcliffe section, a dense grid of twins and brick-and-block rowhomes built largely from the late 1920s through the early 1950s along Providence Road, Oak Lane, and South MacDade Boulevard, with the median home dating to around 1953. A home inspection covers every major system of the house and tells you what you are actually buying before you sign. I evaluate the foundation and structure, the roof and attic, the electrical panel and accessible wiring, the plumbing supply and waste lines, the heating and cooling equipment and its distribution, the exterior envelope and site grading, and the interior finishes, windows, and doors. In Darby Township's housing stock the structural story usually starts at the foundation, because these homes sit on poured concrete and concrete block set into ground that drains poorly and a water table that runs high near the creek corridors. I check the basement for active water entry, efflorescence on block, the condition and function of any sump pump, and whether earlier waterproofing was a real fix or a cosmetic patch. On the roofs I look at the age and remaining life of the covering and the flat or low-slope sections common on rowhomes, which fail differently than pitched roofs. The electrical and the heating systems in these homes have almost always been changed more than once over seventy-plus years, and the value of the inspection is in sorting what was done well from what was layered on top of something older.

When I inspect a Briarcliffe twin or rowhome from the late 1920s through the 1950s, I am not treating it as a generic old house. I am looking at a solidly built structure that has had three or four sets of owners make independent decisions about the panel, the heat, and the plumbing without any of them coordinating, and the consequences of that show up in predictable places. The first is the basement, and it is the single most important room in a Darby Township inspection. This is some of the lowest ground in Delaware County, and I check the foundation walls and slab for moisture history, the sump for proper function, and the exterior grading to see whether the lot sheds water away from the house or channels it back toward the foundation. On the lower streets near Darby Creek and Muckinipattis Creek I weigh flood exposure honestly, because the south end of the township sits in a real floodplain and a buyer deserves to know what that means for basement water management and insurance. The second pattern is the electrical. These homes were wired generations ago and upgraded piecemeal, so I look hardest at the junctions where old circuits meet newer work — remnant knob-and-tube or early armored cable left in attic and wall cavities, overcrowded panels from added circuits, and breakers that do not match the wire they protect. The third is heating: many of these houses were converted from oil to gas, and a conversion done without proper chimney liner sizing leaves a system that runs but can allow flue condensation and carbon monoxide spillback, so I evaluate the venting, not just whether the unit fires. The fourth is the clay sewer lateral. After seventy years under mature street trees, root intrusion and bellied sections are not a possibility here, they are an expectation, and I recommend a sewer scope on most Darby Township homes unless there is documentation that the lateral was replaced. I am independent — I never do repairs and I have no relationship with the seller, the agent, or any contractor, so there is no incentive in my report except telling you what is true. Buyers looking next door in Glenolden meet very similar construction. I encourage every client to attend the inspection and walk the house with me so I can show you each finding in person, separate the safety issues from the cosmetic ones, and answer your questions before you commit to anything.

What does Bob check during a Darby Township home inspection?

Bob approaches every Darby Township inspection per ASHI and InterNACHI Standards of Practice. With 1920s–1950s housing stock dominant in Darby Township, he focuses on the era-specific concerns that affect early to mid-20th century construction in Delaware County.

Because so much of Darby Township's housing stock predates 1940, original wiring is a recurring finding here. Bob wrote a detailed field guide on knob-and-tube wiring in Philadelphia-area homes — how to identify it, when it is genuinely hazardous, and what insurers require.

What are common issues in Darby Township homes?

Based on 20+ years inspecting early to mid-20th century homes in Delaware County, these are the issues Bob finds most often in Darby Township's 1920s–1950s housing stock:

• 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
