Norwood, Delaware County
What home inspection and mold testing services are available in Norwood?
Norwood is one of Delaware County's most intact railroad suburbs, and its housing stock reflects almost every decade of development from 1873 through the postwar years. The borough's first lots went on sale in 1872–73 under a plan commissioned by developer John Cochran and drawn by landscape architect Robert Morris Copeland — the same designer who laid out neighboring Ridley Park. That Copeland plan gave Norwood its curved residential streets, generous lots for the era, and the deep front porches that remain a defining feature of the housing stock today. By the 1890s, as gas, water, sewer, and electric infrastructure arrived, the first major building wave was underway. The result is a concentration of Craftsman bungalows, American Foursquares, and early Colonial Revivals clustered along Delaware Avenue, Mohawk Avenue, Seminole Avenue, and Winona Avenue — the streets that make up the East Woodlawn and Duffwyn sections developed largely by the Duffee family in the 1890s. Locals still refer to the Duffwyn area as the 'Four Hundreds' for its address range. Chester Pike anchors the commercial spine, but it's the residential blocks running between it and the SEPTA Wilmington/Newark Line — Norwood Station opened September 1, 1875 — that define the borough's character. For a home buyer or seller, that character comes with specific inspection priorities. Knob-and-tube wiring is the headline issue in Norwood's pre-1940 stock. These systems were code-compliant when installed, and in many bungalows and Foursquares the visible branch wiring in the main living areas was updated decades ago — but the attic runs frequently were not. Partial replacement is the norm in Norwood, not the exception: you'll find a modern panel at the meter, modern Romex in the kitchen and bathrooms, and original K&T still active in the attic serving two or three circuits. Insurance carriers flag active K&T, and any buyer financing through a conventional lender may face underwriting questions if it's disclosed. Galvanized steel supply piping is the second major concern in late-19th and early-20th-century homes. After 80–100 years, galvanized corrodes from the inside out; you lose pressure, pick up rust discoloration at fixtures, and risk pinhole leaks at fittings. And beneath the yards and streets of Norwood's older sections, the original sewer infrastructure installed in the 1890s means clay lateral lines — brittle with age, susceptible to root intrusion from the mature street trees that line Delaware Avenue and its cross-streets. A camera scope of the lateral is standard practice in this borough and worth every dollar. Post-WWII Cape Cods and ranchers on the borough's edges present a different inspection profile — aluminum wiring in some 1960s–1970s examples, aging HVAC, and flat-roof additions — but the density of pre-war housing in Norwood's core means the older-home checklist applies to the majority of transactions here.
I've inspected a lot of front-porch bungalows in Delaware County over 20 years, and Norwood's are some of the most consistently well-built — and consistently well-aged — I walk through. When I pull up to a Craftsman on Mohawk or Winona, I already have a mental picture of what I'm likely to find: a full basement with original stone or block foundation walls, a first floor that was probably updated in the 1970s or 1980s, and an attic that hasn't been touched since the house was built. That attic is where the story usually is. I'll find the knob-and-tube porcelain cleats still in place, cloth-wrapped conductors running to junction boxes that predate the NEC requirement for accessible covers, and in some cases insulation blown right over the top of active K&T runs — a fire hazard that's invisible until you're up there with a flashlight. I note every circuit I can identify, photograph the panel to cross-reference breaker count against active K&T runs, and flag it clearly in the report so your insurance agent and lender have exactly what they need. In the basement, I'm running every faucet and watching the pressure at the fixture while I check the supply lines. Galvanized pipe that's 90 or 100 years old will often hold pressure in a static test but reveal reduced flow under simultaneous draw. I check the color at the toilet tank — rust staining inside the tank is a reliable tell for galvanized corrosion upstream. The drain stack in a pre-1920 Norwood home is almost always cast iron, and I'm listening to it run while I'm inspecting the basement ceiling; a stack that's been patched with rubber couplings at multiple points is telling me it's been failing section by section for years. I recommend a camera scope of the lateral on virtually every pre-1950 Norwood transaction. The clay lines under the East Woodlawn streets and the Duffwyn sections are old, and the mature trees along Delaware Avenue send roots exactly where you'd expect. I've seen laterals that looked fine at the cleanout and were 60% obstructed 30 feet out. That's a $4,000–$8,000 repair, and it's entirely knowable before you close. The post-WWII ranchers and Cape Cods on Norwood's periphery are a different conversation — newer electrical, copper supply, and cast-iron or early PVC drains — but they bring their own inspection points: aging oil-to-gas conversion furnaces, flat-roof additions with failed membrane seams, and 1960s aluminum wiring in some examples. Every house in this borough gets the same systematic inspection; the pre-war ones just consistently produce more findings to talk through. I'll walk you through every one of them on-site and have your full photo report ready within 24 hours.
What does a home inspection in Norwood include?
Bob approaches every Norwood inspection per ASHI and InterNACHI Standards of Practice. With 1890s–1930s housing stock dominant in Norwood, Bob pays particular attention to the era-specific issues that affect late 19th and early 20th century construction in Delaware 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 — 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 — 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.
How does mold testing work in Norwood?
Pre-1920 homes are among the highest-risk properties for mold growth due to stone foundations that wick moisture, lime mortar joints that crack over time, and original drainage systems that predate modern waterproofing.
Porous stone foundations with no vapor barrier allowing constant moisture migration
Original clay drainage tiles that crack and clog, directing water toward the foundation
Lime mortar repointing gaps that create moisture entry points
Unventilated basement spaces with earth or deteriorating concrete floors

Bob walks you through exactly what the lab results mean — no jargon, no panic. All samples go to a PRO-LAB certified lab with results in 2-3 days. Mold testing starts at $275.
