Radnor, Delaware County

What does a home inspection in Radnor include?

A home inspection in Radnor, 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 ASHI and InterNACHI standards, with a full photo-documented digital report delivered inside 24 hours.

Radnor Township sits at the heart of Pennsylvania's Main Line, a stretch of affluent communities that grew up alongside the Pennsylvania Railroad in the late 19th century. The township encompasses Wayne, the commercial and civic hub, as well as the walkable neighborhoods surrounding Villanova University and Eastern University. Landmark institutions define the area: Villanova University with its Augustinian roots and Gothic Revival architecture, the Radnor Hotel on East Lancaster Avenue, Wayne Art Center, the historic Wayne Presbyterian Church, and the Radnor Township Building anchor a community that takes preservation seriously. Shopping along Lancaster Avenue in Wayne -- from Pour Richard's to local boutiques and the Wayne Farmers Market -- reflects a neighborhood that blends old-money character with modern convenience. Radnor Memorial Library serves residents across the township, while the Radnor Trail offers a green corridor connecting neighborhoods from Wayne to Ithan. The Devon Horse Show grounds, just over the border, speaks to the equestrian culture embedded in the region. Residential streets like Chamounix Road, Conestoga Road, and Roberts Road are lined with stone Colonials, Tudor Revivals, and Georgian estates, many of them predating World War I. The school district -- Radnor Township School District, including Radnor High School -- draws buyers from Philadelphia and beyond. Wayne Train Station on SEPTA's Paoli/Thorndale Line connects residents directly to Center City, making the township a perennial target for buyers relocating from the city. The housing stock reflects that long history of desirability: a large share of homes were built between 1890 and the 1940s, with Craftsman bungalows and Victorian frame houses filling in between the grander stone estates.

What I see consistently in Radnor is what you would expect from a township where many homes were built before the Great Depression and never fully modernized behind the walls. The curb appeal is exceptional -- stone facades, slate roofs, original millwork -- but the mechanical infrastructure underneath often tells a different story. Knob-and-tube wiring is still energized in a surprising number of these homes, sometimes hidden beneath blown-in insulation that was added decades later, which creates a fire hazard that does not show up unless you know where to look. Stone foundations in the older Colonials and Tudor Revivals are porous by design; lime mortar joints that have been slowly eroding for a century create pathways for water intrusion that stain basement walls and feed mold behind finished paneling. And the original clay sewer laterals that served these homes in the 1910s and 1920s are at the age where root intrusion and bellied sections are the norm rather than the exception -- a sewer scope is something I recommend for virtually every pre-1940 home I inspect in this township. Buyers relocating from newer construction in Haverford or Bryn Mawr are sometimes surprised by how much deferred maintenance accumulates quietly in a home that looks immaculate from the street. My job is to make sure none of it surprises you after closing. I document every finding with photographs, give you a plain-language cost range for repairs, and sort issues into what needs attention now versus what can be planned over the next few years. Call 610-348-6728 to schedule.

What does Bob check during a Radnor home inspection?

Bob approaches every Radnor inspection per ASHI and InterNACHI Standards of Practice. With 1890s–1960s housing stock dominant in Radnor, he focuses on the era-specific concerns 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.

What are common issues in Radnor homes?

Based on 20+ years inspecting late 19th and early 20th century homes in Delaware County, these are the issues Bob finds most often in Radnor's 1890s–1960s 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

Common Questions

What are common home inspection questions in Radnor?

Questions buyers and sellers in Radnor ask us most often — answered directly.

Home inspections in Radnor start at $375. Final pricing depends on the property's square footage, age, and number of systems. Many Radnor homes are large pre-1920 stone Colonials and Tudors with complex older systems -- Bob will give you an exact quote when you call. Reach him at 610-348-6728.
Bob inspects every accessible major system per ASHI and InterNACHI standards: foundation and structural framing, electrical panels and visible wiring, plumbing supply and drain lines, HVAC equipment and distribution, roof covering and attic structure, exterior envelope including masonry, windows, and doors, insulation, and ventilation. You receive a photo-documented digital report within 24 hours.
Most Radnor inspections run 2-3 hours. Larger pre-1920 stone estates, carriage houses, and homes with multiple HVAC systems or finished basements often run closer to 3.5 hours. Bob encourages buyers to attend so he can walk through findings on site and answer questions before the written report arrives.
Every home inspection in Radnor is performed in person by Bob Klebanoff -- the same licensed InterNACHI- and ASHI-certified inspector who shows up to every appointment. No rotating technicians, no subcontractors, no handing the job off once you book. Findings are documented with photographs and a plain-language repair-cost range, sorted into immediate safety concerns versus planned-maintenance items, so you can decide whether to negotiate, accept, or walk. Nothing gets buried in jargon.
Knob-and-tube wiring is one of the most critical findings Bob documents in Radnor's pre-1920 housing stock. The wiring itself is not automatically unsafe, but when insulation has been blown over active knob-and-tube circuits -- a common retrofit in this area -- heat cannot dissipate and fire risk increases significantly. Bob checks accessible attic spaces, basement joists, and panel configurations to determine whether knob-and-tube is still energized and whether it has been compromised by insulation or improper splices. Many insurers require remediation before issuing a homeowners policy, so this finding has real transaction implications.
Stone and rubble foundations with lime mortar joints are a defining feature of Radnor's pre-1920 construction and require a different evaluation approach than poured concrete. Bob checks for shifting stones, mortar erosion, active water seepage pathways, efflorescence, and interior moisture staining that indicates chronic water intrusion. He also looks for evidence of prior waterproofing attempts -- interior drain tile, parging, or sump installations -- that may be masking ongoing foundation movement. Settlement cracks that follow the mortar lines are common; cracks that cut through the stone itself warrant a structural engineer review.
Bob strongly recommends a sewer scope for any Radnor home built before 1950. Original clay sewer laterals from that era are now 75 to 110 years old -- well past their service life -- and root intrusion, bellied sections, and joint separation are routine findings. A lateral replacement in Delaware County typically runs $8,000 to $15,000 depending on depth and length, making it one of the larger surprises buyers encounter post-closing. Bob can coordinate a scope during the same inspection window so you have the information before your inspection contingency expires.
Radnor's mid-century housing stock -- Cape Cods, split-levels, and early ranch homes built between 1945 and 1965 -- presents a different set of concerns than the pre-1920 estates. Bob frequently documents original 60-amp service panels that are undersized for modern loads, galvanized steel supply lines that have narrowed internally from mineral buildup, and original oil-to-gas HVAC conversions that were not always vented correctly. Asbestos-wrapped ductwork and floor tile are also common in this era. These are manageable issues, but they affect both negotiation strategy and homeowners insurance eligibility.
Yes. Many of Radnor's larger properties include detached carriage houses, guest quarters, or pool houses that were built in the same pre-1920 era as the main residence and share the same deferred-maintenance profile. Bob inspects secondary structures as part of the same appointment when they are accessible. Pricing is based on total square footage across all structures. If you are purchasing a multi-structure property, mention it when you call so Bob can allocate the right amount of time -- reach him at 610-348-6728.
Radnor Township does not require a municipal Use and Occupancy (U&O) inspection as a condition of resale -- that requirement applies to some neighboring municipalities but not Radnor. That said, buyers purchasing in Radnor should not treat this as an excuse to skip due diligence. A third-party inspection by an ASHI- or InterNACHI-certified inspector is the only way to get an objective, buyer-side assessment of the property. Municipal inspectors, when they exist, do not work for you and do not produce the kind of detailed, photo-documented report that supports negotiation.
Yes -- Bob recommends radon testing on every Radnor purchase. Delaware County sits in Pennsylvania's elevated radon zone, and Radnor's stone and rubble foundations with their natural void spaces and mortar gaps create more entry pathways than poured concrete. EPA action level is 4 pCi/L. Bob has documented readings well above that threshold in Radnor basements that showed no visible signs of a problem. Testing adds a small cost upfront; a mitigation system runs $800 to $1,500 if needed. It is a straightforward negotiating item when caught before closing.
Absolutely. Wayne and Villanova are Bob's core Main Line territory, and he routinely schedules back-to-back inspections across Radnor Township, St. Davids, and Berwyn in a single day. If you're comparing properties across those towns -- which often means comparing a Wayne colonial to a Radnor Tudor to a Villanova ranch from different eras -- Bob can walk you through what each property's age and construction type means for long-term cost before you make a final decision. Call 610-348-6728 to coordinate multiple inspections in the same window.
