Delaware County is the most densely populated county in Pennsylvania outside of Philadelphia — a compact mix of urban rowhomes, suburban colonials, post-war Cape Cods, historic borough Victorians, Main Line estates, and newer construction. Since 1997, ValueGuard has completed over 94,000 home inspections across Greater Philadelphia — more than any other inspection company. That range here means aging electrical panels, galvanized and knob-and-tube wiring, stone foundations, slate roofs, and aging sewer laterals all turn up, alongside a radon profile among the highest in the country. Our ASHI-certified home inspectors know exactly what to look for in each.

i. Why this county is different
Delaware County demands a different home inspector.
Post-war Cape Cods, historic borough Victorians, the highest radon risk in the country, and dense older neighborhoods on aging laterals. Generic inspectors miss what matters in Delaware County. Here’s what we focus on:
Post-War & Mid-Century Homes
Upper Darby, Drexel Hill, and Havertown are filled with post-war Cape Cods and colonials built between the 1940s and 1960s. These homes commonly carry aging electrical panels, galvanized plumbing, and knob-and-tube or aluminum wiring — all requiring careful evaluation.
Highest Radon Risk in the Country
Delaware County is EPA Zone 1 — the highest radon classification. Pennsylvania’s statewide indoor average is 7.3 pCi/L, nearly double the EPA’s 4.0 pCi/L action level. Every Delaware County buyer should include radon testing — no exceptions.
Historic Borough Properties
Media, Swarthmore, and Lansdowne hold some of the county’s oldest, most character-rich homes — stone foundations, original plaster walls, aging service lines, and slate roofs that demand an inspector who knows historic construction inside and out.
Dense Older Neighborhoods
As the densest county outside Philadelphia, Delco packs rowhomes and twins onto tight blocks from Darby to Clifton Heights — shared walls, close-set foundations, and aging shared infrastructure that suburban-focused inspectors routinely overlook.
Aging Sewer Laterals
The county’s dense older neighborhoods — from Upper Darby to Ridley Park to Media borough — sit on aging clay and cast iron sewer laterals prone to root intrusion and collapse. A camera inspection before closing is the only way to know the line’s true condition.
An Active, Competitive Market
Newtown Square, Glen Mills, and Springfield are among the county’s most active markets. Same-week scheduling and next-business-day reports keep your inspection contingency on track in any competitive offer. Seven days a week.

The Delaware County Radon Warning
Delaware County is EPA Zone 1 — the highest radon risk classification. Pennsylvania’s statewide average indoor radon level is 7.3 pCi/L, nearly double the EPA’s 4.0 pCi/L action level. Radon is colorless, odorless, and the second leading cause of lung cancer in the United States. Levels can vary significantly from house to house even on the same street, and the only way to know a home’s level is to test for it. Our DEP-certified technicians use tamper-resistant electronic monitors for accurate 48-hour results. Don’t close on a Delaware County home without testing.
From our recent caseload
Recently inspected in Delaware County.
Six homes from recent ValueGuard inspections across Delaware County — historic Victorians, post-war colonials, stone farmhouses, and suburban stucco. One county, six entirely different inspections. Swipe or use the arrows to see all six.
No. 01
Historic Victorian Stone Home
A character-rich Victorian on a leafy Swarthmore street — stone foundation, original plaster, aging service lines, and the kind of period detail that rewards an inspector who knows historic construction.
No. 02
Classic Brick Colonial
A classic brick colonial in the borough of Media — the kind of established home where a buried sewer lateral and original systems both deserve a camera and an experienced eye before closing.
No. 03
Stone & Frame Colonial
A handsome stone-and-frame colonial in fast-growing Newtown Square, where established character meets newer additions — and where radon testing belongs on every inspection in this EPA Zone 1 county.
No. 04
Brick & Vinyl Colonial
A well-kept brick-and-vinyl colonial on a classic Havertown block — a post-war home where aging panels, plumbing, and a buried lateral all benefit from a thorough, experienced look.
No. 05
Post-War Semi-Detached
A classic Drexel Hill semi-detached on a dense, tree-lined block. Shared walls and aging shared infrastructure make these post-war homes a place where a sewer scope and a careful systems check really earn their keep.
No. 06
Stucco Colonial
A stately stucco colonial on the Delaware County edge of the Main Line. Stucco and EIFS exteriors demand a trained eye for hidden moisture — one of the most overlooked issues on homes like this.

ii. The four services that matter most
Four services every Delaware County buyer needs.
Radon Testing
Delaware County is EPA Zone 1 — the highest radon risk classification. Pennsylvania’s statewide indoor radon average is 7.3 pCi/L, nearly double the EPA’s 4.0 pCi/L action level. Radon is colorless, odorless, and the second leading cause of lung cancer in the US. Our DEP-certified technicians deliver accurate 48-hour results.
Termite Inspection
Delaware County’s older homes — particularly post-war properties with wood framing in close contact with soil and aging foundations — create ideal conditions for termites and wood-destroying insects. A certified WDI inspection is required by most lenders and essential for any purchase here.
Sewer Scope Inspection
The county’s dense older neighborhoods — from Upper Darby to Ridley Park to Media borough — sit on aging clay and cast iron sewer laterals prone to root intrusion and collapse. A camera inspection before closing is the only way to know the line’s true condition.
Mold Testing
Older Delaware County homes — particularly those with finished basements, stone foundations, and aging HVAC — are susceptible to moisture intrusion and mold growth. Our certified mold testing covers air sampling and surface testing, giving you a complete picture before you commit.
