Wynnewood, Montgomery County

What home inspection and mold testing services are available in Wynnewood?

Stone twins and center-hall colonials line the blocks between Lancaster Avenue and Montgomery Avenue, and in Wynnewood the pattern repeats street after street: fieldstone and schist facades, slate roofs, deep front porches, and full basements dug back when coal was still the fuel of choice. Most of the housing stock went up between the 1890s and the 1940s, built out in waves around the Wynnewood station on SEPTA's Paoli/Thorndale Line as the Main Line filled in westward from Philadelphia. Head south toward City Avenue near Friends' Central School, or north along Penn Road and Wynnewood Avenue, and the construction eras shift a decade at a time, from turn-of-the-century masonry to tighter 1920s twins to the postwar infill that took the last open parcels. Haverford Road and Wynnewood Road carry the daily traffic between the Wynnewood Shopping Center and Lankenau Medical Center, and the homes set back behind those corridors often sit on lots that slope more than their owners realize. That grade matters here. Foundations of this vintage were laid up in stone with lime mortar and no vapor barrier, original clay laterals still run under some front yards, and a century of downspout reroutes, patio pours, and finished-basement projects has quietly changed how water moves around these houses. Add decades of renovation on top of that, rear additions, converted third floors, and modern kitchens dropped into original framing, and evaluating a Wynnewood property is rarely a matter of looking at one system in isolation.

The condition Bob runs into most often in Wynnewood is a basement that was finished long after the house was built, with framing and drywall set tight against a stone wall that was never meant to stay dry. From the stairs it all looks finished and fine. Behind the panel there is efflorescence on the stone, damp framing at the sill plate, and sometimes an odor the sellers have been managing with a dehumidifier. That is exactly the point where hiring three separate vendors starts costing you the contingency window. Bob is InterNACHI and ASHI certified and PRO-LAB certified for mold, so when a Wynnewood home inspection turns up a damp stone cellar, cupped flooring over a crawl area, or blown insulation packed over live knob-and-tube, he can pull mold air samples and run indoor air quality testing during that same visit instead of sending you out to book a second appointment with somebody else. One inspector, one trip, one report. He has worked this pre-war corridor for more than 20 years and sees the same foundation, slate, and wiring patterns a few minutes east in Narberth, which is how he tells ordinary century-old aging apart from the findings that actually cost real money. Whether you are buying, listing, or just trying to settle a question about your own house, call Bob directly at 610-348-6728 and he will walk you through what the property likely needs before you commit to anything.

What does a home inspection in Wynnewood include?

Bob approaches every Wynnewood inspection per ASHI and InterNACHI Standards of Practice. With 1890s–1940s housing stock dominant in Wynnewood, Bob pays particular attention to the era-specific issues that affect late 19th and early 20th century construction in Montgomery 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 Wynnewood?

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

Clear Results & Honest Recommendations

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 $290.

What are common issues in Wynnewood homes?

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

★★★★★
"Bob spent almost five hours on our 1918 Wynnewood stone colonial. He physically climbed to the third floor, went into the attic, walked the slate roof, and flagged things the listing photos conveniently angled away from. The report arrived within 24 hours and the detail was exceptional."

Common Questions

What are common home inspection questions in Wynnewood?

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

A full home inspection in Wynnewood starts at $325. The final number depends on the size, age, and condition of the property, so a compact 1920s twin near the Wynnewood station prices differently than a large pre-war stone colonial with a finished third floor, a rear addition, and a walk-out cellar. Bob quotes per property rather than off a flat chart, and he tells you the number before he schedules. Every inspection includes a digital report delivered within 24 hours with photographs of each finding, so you are not working from handwritten notes when you go back to the seller. Bob performs the inspection himself and will stay on the phone afterward to explain anything in the report. For a quote on a specific Wynnewood address, call 610-348-6728.
Three core services, all performed personally by Bob with no subcontractors. Residential home inspection starts at $325 and covers structure, roof, electrical, plumbing, heating and cooling, and the interior and exterior. Mold testing with laboratory air sampling starts at $290, which matters in Wynnewood because so many homes here sit on stone foundations with finished basements added later. Indoor air quality testing also starts at $290 and looks at what is actually circulating through the house, useful in older homes with coal-era basements, aging plaster, and renovation dust. Bob also handles radon testing, wood-destroying insect inspections, pre-listing inspections for sellers, new construction and 11-month warranty inspections, and post-remediation clearance testing. The same InterNACHI and ASHI certified inspector shows up for all of it.
Yes. Wynnewood is core territory for All Seasons, and Bob has been inspecting homes in Lower Merion Township and along the Main Line for more than 20 years. He is based in Wyncote, so Wynnewood is a short drive and there is no travel surcharge. Inspections here are usually scheduled within the week, and Bob answers his own phone rather than routing you through an office or a scheduling service. If your agreement of sale has an inspection contingency clock running, say so when you call and he will work to fit you in sooner. He covers the surrounding Lower Merion communities on the same basis, so if you are looking at more than one property along the corridor, the same inspector can handle each of them. Call 610-348-6728 to check availability.
It comes up regularly. Homes built here between the 1890s and the 1920s were originally wired with knob-and-tube, and while many Wynnewood houses have been rewired over the decades, the work was often partial. Kitchens and baths got updated circuits while original runs stayed energized behind plaster walls, in closets, and up in the attic. The bigger risk is what happened later. When blown insulation is added to an attic floor over active knob-and-tube, the wiring loses the open-air cooling it was designed around, and that is a genuine fire hazard rather than a paperwork issue. Bob traces what is still live, checks the service panel and its capacity, looks for junctions buried without boxes, and tells you plainly whether you are looking at a small electrician visit or a whole-house rewire.
Both are durable and both have maintenance clocks that most buyers underestimate. Stone foundations were laid up with lime mortar, which is softer than modern mortar by design and erodes over a century of freeze and thaw. Bob looks for shifting stone, open joints, seepage staining, and whether past repointing was done with the wrong material, which traps moisture instead of releasing it. On the roof, original slate can outlast several asphalt roofs, but individual slates crack and slide, and the flashing and copper valleys usually fail long before the slate does. Bob checks slate condition, flashing at chimneys and dormers, and gutter and downspout discharge, because water dumped at the base of the wall is what turns a sound stone foundation into a wet basement.
Any time the house has a stone or rubble foundation and a finished basement, which describes a large share of Wynnewood properties. Framing and drywall placed against porous stone with no vapor barrier hides exactly the conditions mold needs, and you often cannot see it without sampling. Bob recommends adding mold air sampling starting at $290 when an inspection turns up efflorescence, a musty smell, a dehumidifier running in a listing, water staining at the sill plate, or a recently remodeled cellar in a century-old house. Indoor air quality testing starting at $290 makes sense in homes with original coal-era basements, deteriorating plaster, or a renovation that disturbed old paint and trim. Because Bob is PRO-LAB certified, he can take the samples during the same appointment rather than sending you to a separate company.
It is usually worth it. Main Line buyers arrive with their own inspector and a short contingency window, and on a pre-war Wynnewood house that inspector will find things: aging flashing, an original electrical service, galvanized supply lines near the end of their service life, a clay sewer lateral with root intrusion, a coal chute opening that was never properly sealed. Finding those yourself first means you set the price and pick the contractor instead of negotiating under deadline pressure. A pre-listing inspection also gives you a photo-documented report you can hand to serious buyers, which builds trust and cuts down on renegotiation. Bob performs pre-listing inspections at the same starting rate as a buyer inspection. Call 610-348-6728 to talk through timing before you go on market.
Because the problem is usually outside the house, not in the wall. Many Wynnewood lots slope toward the dwelling, and the original drainage was built around clay tile and simple grading rather than modern waterproofing. Over a hundred years, clay laterals crack and fill with roots, downspouts get shortened or rerouted during landscaping, patios and driveway aprons get poured at a pitch that sends water back toward the wall, and window wells fill with leaves. The stone foundation itself may be in fine shape and still take on water every spring storm. Bob walks the exterior grade, traces where every downspout actually discharges, checks window wells and the base of the wall, and identifies the entry path so you fix the cause instead of paying for interior drainage you may not need.
