Aldan, Delaware County

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

Trains still pull into Aldan station on SEPTA's Media/Wawa Line, and that one detail explains most of what a buyer finds here. The borough grew up along the old Pennsylvania Railroad branch as a commuter suburb, so instead of the tight rowhouse blocks of Collingdale and Darby, Aldan filled in with detached houses and twins set back on real yards, most of them built between the 1890s and the 1940s. Walk the side streets off Providence Road or Clifton Avenue and you can read the timeline in the porches: deep wraparound porches and slate roofs on the oldest stock, then Foursquares and Colonial Revivals, then modest infill on whatever lots were left. It is a small borough, tucked between Clifton Heights, Lansdowne, Collingdale and Yeadon, and it stays residential nearly wall to wall, with Aldan Elementary School and Aldan Union Church as the fixed points and the commercial traffic pushed out to Baltimore Pike above and MacDade Boulevard below. The age is what matters for property condition. Foundations here run from rubble stone with lime mortar in the oldest houses to early poured concrete and block in the 1920s and 1930s work, and almost every basement has been through at least one waterproofing attempt. The ground drains toward the Darby Creek watershed, so downspout routing and lot grading decide which basements stay dry through a wet spring. Nearly every house has also been rewired, reroofed or converted off coal heat at least once, and the quality of that work varies enormously from block to block.

The pattern Bob sees most often in Aldan is a basement that was finished or half finished decades ago and never opened up since. Paneling and a drop ceiling go up against a stone or early block wall, the sump discharge gets aimed at the wrong corner of the yard, and by the time a buyer walks through, whatever is happening behind that paneling is invisible. Knob-and-tube wiring is the other recurring one. Plenty of Aldan houses were partially rewired at some point and the original circuits were left energized behind plaster, sometimes buried under blown-in attic insulation. Bob looks for both on every inspection in this borough. Because he handles all three services himself, a finding here does not turn into three separate phone calls. If a home inspection turns up a musty finished basement or a water stain on a floor joist, he can collect mold samples on the same visit and send them to a PRO-LAB certified lab, and when the concern is broader he can run an indoor air quality panel for the coal dust, lead paint dust and combustion byproducts that come with century-old houses and old heating conversions. One inspector, one visit, one report you can hand to a seller, a lender or a contractor. Bob works the same housing stock in Clifton Heights and across eastern Delaware County, so he knows how these homes behave season to season.

What does a home inspection in Aldan include?

Bob approaches every Aldan inspection per ASHI and InterNACHI Standards of Practice. With 1890s–1940s housing stock dominant in Aldan, 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 Aldan?

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 Aldan 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 Aldan'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

Common Questions

What are common home inspection questions in Aldan?

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

Home inspections in Aldan start at $325. The final price depends on the size, age and condition of the property, so a compact 1,200 square foot twin off Clifton Avenue prices differently than a larger detached Foursquare with a finished third floor and a converted basement. Aldan's pre-1920 and 1920s housing stock often takes longer to inspect properly because there is more to document: stone foundations, original wiring runs, slate roofs and decades of layered renovation work. You get a digital report within 24 hours with photos of every significant finding, written in plain language so you can act on it rather than decode it. Bob walks you through the findings by phone as well. Call 610-348-6728 for an honest quote on your specific Aldan address.
Three services, all performed personally by Bob Klebanoff. Full home inspections for buyers and sellers start at $325 and cover structure, roof, electrical, plumbing, heating and cooling, and the interior. Mold testing starts at $290 and includes air or surface sampling with PRO-LAB certified lab analysis. Indoor air quality testing also starts at $290 and covers particulates, VOCs and combustion byproducts. There are no subcontractors and no rotating technicians. The person who inspects your Aldan house is the person who takes the samples and writes the report, which matters when one finding leads to another. Many Aldan homeowners start with a home inspection and add testing once something shows up in the basement or an old converted attic space. Call 610-348-6728 to sort out which one you actually need.
Yes. Aldan is core territory for All Seasons and has been for more than 20 years. Bob is based in Wyncote and works Delaware County constantly, including Aldan and the neighboring boroughs of Clifton Heights, Lansdowne, Collingdale, Yeadon, Glenolden, Darby and Sharon Hill. Because Aldan is compact and the housing stock is consistent, he can usually get to a property quickly, and scheduling around a tight contingency window is normally not a problem. Weekend and early morning appointments are available when a settlement date is pressing. If you are buying, selling or just trying to settle a moisture question in your own house, call 610-348-6728 and Bob will confirm availability for your street and tell you honestly how soon he can be there.
Knob-and-tube wiring is at the top of the list. Many Aldan houses from the 1890s through the 1910s were only partially rewired, and the original cloth-wrapped circuits are still live behind plaster walls. That becomes a real fire risk when blown-in insulation was added over active knob-and-tube in the attic, which is a common combination here. The second is stone and rubble foundation deterioration. Lime mortar joints erode over a century, stones shift, and water finds the gaps. Bob also regularly finds gas conversions from original coal or oil systems with undersized or poorly vented flue connections, original clay sewer laterals with root intrusion, and aging slate roofs where the slate is sound but the flashing and copper gutters have failed. None of these are automatic deal breakers. They are budget items you should know about before closing.
Any Aldan house built before 1978 can have lead paint, and given that most of the borough went up between the 1890s and the 1940s, the odds are high on original trim, window sashes, door frames and exterior surfaces. Intact, well maintained paint is generally stable. The risk comes from friction surfaces such as double-hung window channels, from deteriorating exterior paint that sheds into the soil near the foundation, and above all from renovation. Sanding or dry scraping old trim without containment puts lead dust through the whole house. Bob documents suspect painted surfaces and their condition during the home inspection, and if you are concerned about what is already circulating in the air, an indoor air quality test starting at $290 measures the particulate side of it. Call 610-348-6728 if you are planning a renovation on an older Aldan property.
The clearest trigger is a basement. Aldan basements sit on stone or early block, most have no vapor barrier, and a lot of them were finished with paneling and carpet at some point in the last 50 years. If you smell must, see staining at the base of a wall, or the previous owner finished the space and you cannot see the original wall, testing is worth the $290. The second trigger is a converted attic or a sealed-off room with poor ventilation, which is common in the borough's larger Foursquares. The third is symptoms that improve when you leave the house. Bob can add mold sampling or an air quality panel to a scheduled home inspection so you are not paying for a second trip, and lab results come back in 2 to 3 business days.
Usually because the water was never stopped outside. Aldan sits on ground that drains toward the Darby Creek watershed, and most of these houses still rely on original clay drainage tile that has cracked, sagged or filled with roots over the decades. An interior french drain and a sump pump move water that has already reached the foundation, which helps, but it does nothing about the source. Bob looks at the whole path: roof drainage, downspout extensions, the grade in the first six feet around the house, window wells, and whether the sump discharge is dumping right back against the foundation, which he finds more often than you would expect. On older stone walls he also checks whether repointing left open joints. Fix the exterior first and the interior system stops working overtime.
Yes, and arguably more than on a newer house. Square footage is not what drives risk in Aldan. Age is. A 1,300 square foot twin off Providence Road can carry the same century-old stone foundation, the same live knob-and-tube behind the plaster, the same slate roof with tired flashing and the same clay sewer lateral as a much larger property. Twins add one more thing worth attention: a shared party wall and often a shared or adjoining roof line, where a neighbor's deferred maintenance becomes your water problem. Bob inspects the party wall condition, the flashing where the two roofs meet and any signs of moisture tracking across. At $325 to start, an inspection on a modest Aldan house is still the cheapest information you will buy in the whole transaction. Call 610-348-6728.
