What does a home inspection in Chestnut Hill include?

A home inspection in Chestnut Hill, Philadelphia 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.

Chestnut Hill sits at the northwest edge of Philadelphia inside ZIP 19118, a National Historic District running along the famous cobblestone stretch of Germantown Avenue from Cresheim Valley up past the Wissahickon Creek gorge and Valley Green Inn. The housing stock is defining: late-Victorian through 1920s Wissahickon-schist stone singles and estate-scale twins on Norwood, West Moreland, West Southampton, Rex, Evergreen, and Willow Grove Avenue, with significant work by Addison Hutton, Frank Miles Day, and Mellor Meigs & Howe. Slate roofs, copper valleys, leaded-glass casements, and hand-hewn timber framing are the rule rather than the exception, and a real share of parcels still carry original servant-wing layouts, coal chutes, and sill-height cast-iron plumbing stacks. With Morris Arboretum of the University of Pennsylvania on one flank, Woodmere Art Museum nearby, Pastorius Park mid-neighborhood, Chestnut Hill Hospital serving the corridor, and Chestnut Hill College, Chestnut Hill Academy, Springside Chestnut Hill Academy, and Jenks Elementary all feeding demand, turnover is steady but the homes are rarely simple. Inspecting a Chestnut Hill estate is closer to evaluating a century-old institutional building than a standard resale, and the report needs to reflect that reality honestly.

I have been inspecting stone homes in 19118 for over twenty years, and what I keep telling buyers in Chestnut Hill is that the most expensive surprises are the ones the listing photos do not show. On a Rex Avenue estate last spring I walked a 1908 stone-and-slate single where the copper valleys had been face-nailed during a quick patch, the terra-cotta flue liners had hairline cracks at the first offset, and a capped oil-tank fill pipe was still visible behind a rhododendron on the west elevation, flagging a buried tank the disclosure did not mention. I put a borescope through the plaster at a second-floor closet and found active knob-and-tube feeding the old servant wing under blown cellulose. That is typical Chestnut Hill: slate roof technically intact but past its 100-year service window, schist foundation with failed pointing at the rear grade, lead water service still running from the pre-1920 main under Germantown Avenue, and one or two surprises the seller genuinely did not know about. My job is to give you a plain-English report you can hand to your slate contractor, your stack-lining specialist, and your historic-commission consultant. If you are comparing homes across the line in Mt Airy or further down the Avenue in Germantown, call me at 610-348-6728 and we can talk through what to look for before you even write the offer.

What does Bob check during a Chestnut Hill home inspection?

Bob approaches every Chestnut Hill inspection per ASHI and InterNACHI Standards of Practice. With 1880s–1940s housing stock dominant in Chestnut Hill, 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 — 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 Chestnut Hill 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 Chestnut Hill's 1880s–1940s 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 Chestnut Hill?

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

Home inspections in Chestnut Hill start at $375. Final pricing depends on square footage, property age, number of outbuildings, and whether add-on services (radon, sewer scope, termite, mold air sampling) are bundled. Call Bob directly at 610-348-6728 — he gives honest per-property quotes on the first call, not a menu price list.
Every Chestnut Hill inspection is run against ASHI and InterNACHI standards and covers foundation and structural systems, electrical panel and accessible wiring, plumbing supply and waste lines, HVAC equipment and distribution, roof and attic, exterior envelope and grading, interior finishes, windows and doors, and insulation and ventilation. You receive a photo-documented digital report within 24 hours.
Most Chestnut Hill inspections run 2-3 hours on-site depending on square footage and property age. Bob encourages buyers to attend — the in-person walk-through at the end is where the report becomes useful, not just something you read later.
Every home inspection in Chestnut Hill 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.
Yes. Chestnut Hill is a National Historic District and most of it falls under Philadelphia Historical Commission exterior review. That means replacing a slate roof with architectural shingle, swapping original wood windows for vinyl, or re-pointing schist with the wrong mortar mix can trigger a violation and a re-do. Bob flags original materials in the report so you know what is protected before you budget for repairs, and he notes where past work may have been done without approval.
Estate parcels along the arboretum edge and up near Northwestern Avenue share a few patterns. Mature canopy keeps slate and copper shaded and damp, so Bob checks valley pans and chimney flashings carefully. Stone foundations sit in soil that stays wet longer, which shows up as efflorescence and mortar failure at the rear grade. Irrigation from estate plantings can also be driving water back toward sills. Bob walks the full perimeter and documents drainage so you understand the maintenance envelope before closing.
Original Chestnut Hill slate is typically Pennsylvania Peach Bottom or Vermont grey-green, and both have service lives in the 100 to 150 year range depending on nails and flashing. Bob looks for delamination, missing slates replaced with asphalt patches, rusted cut nails bleeding through the face, failing copper valleys and step flashings, and granular shale powder in the gutters. If the slate itself is sound but the flashings are spent, that is a reasonable repair. If the field is delaminating broadly, you are looking at full replacement, which runs well into five and sometimes six figures on an estate roof.
Very common. Most homes built before 1920 along Germantown Avenue and the side streets still have a lead service line from the main to the house, even if interior plumbing was updated. Bob checks the service entry at the meter, notes the pipe material and diameter, and flags any visible lead or galvanized-on-lead transitions. Philadelphia Water has a lead service replacement program, and knowing the material before closing helps you plan. Bob also recommends a first-draw water test if the home has been vacant.
On pre-1920 Chestnut Hill estates Bob specifically looks for fill and vent pipe stubs in the landscaping, ghost lines in the basement wall where a tank once stood, and patched concrete where an interior tank was removed. Many estate parcels had 550 to 1000 gallon underground tanks on the side or rear yard, and a surprising number were abandoned in place rather than properly decommissioned. Bob will note anything suspicious in the report, and for higher-risk parcels he recommends a tank sweep by a licensed environmental contractor before closing.
Both, and they do not always agree. Philadelphia Licenses and Inspections has the structural, electrical, plumbing, and mechanical permit record, which is what Bob cross-references against what he sees in the field. The Philadelphia Historical Commission has the separate exterior-review record for designated properties, including approved paint colors, window replacements, and masonry work. Bob will tell you where the field evidence suggests work was done without a permit, and you can then pull the records yourself before closing.
On Wissahickon schist it depends on whether the original lime mortar has just weathered out or whether someone re-pointed with Portland cement in the wrong spots. Lime mortar is soft and sacrificial by design, so mortar loss on its own is normal century-home maintenance. Portland cement pointing on a schist wall traps moisture and spalls the stone, which is a real problem. Bob photographs the joints, notes where settlement cracks are active versus cosmetic, and tells you what a qualified historic mason should be looking at.
Not automatically, but it changes the scope. In Chestnut Hill estates the servant-wing additions were often wired later than the main house and then updated piecemeal, so Bob frequently finds live knob-and-tube buried under blown insulation. That combination is a fire risk and most insurers will require it be removed or de-energized. Bob maps what is live versus abandoned, estimates the scope for a licensed electrician, and gives you the information you need to negotiate a credit or a pre-closing repair.
