Radnor Township anchors the Delaware County side of the Philadelphia Main Line, taking in Wayne, St. Davids, Villanova, Rosemont, Garrett Hill and Radnor, along with Villanova University and the top-rated Radnor Township School District. The housing ranges from late-1800s Victorians and stone estates to 1920s–1940s Tudors and Colonial Revivals, mid-century homes, townhomes and condominiums, and newer custom construction. Homes of this age and value bring specific inspection priorities: stone masonry, slate and older roofs, chimneys, multi-zone mechanical systems, original wiring and plumbing in older homes, stucco on later construction, drainage on wooded lots, and EPA Zone 1 radon throughout. ValueGuard’s ASHI-certified home inspectors in Radnor have been inspecting Main Line homes since 1997 — whether you need a full pre-purchase home inspection of an estate, a colonial inspection, or a condo inspection, you get findings detailed enough to negotiate from a position of strength.

i. Why these homes are different

Main Line estates, high stakes.

Radnor’s housing is among the most architecturally complex on the Main Line. Here’s what a thorough home inspection in Radnor focuses on:

i
Victorian & Stone Estates
Late-1800s and early-1900s estates demand expert attention to stone foundations and walls, slate and tile roofs, chimneys, original wiring and plumbing.
ii
Tudors & Colonial Revivals
1920s–1940s homes carry steep rooflines, stucco and half-timbering, leaded glass and aging boilers that need an experienced eye.
iii
Radon Zone 1
Delaware County, including Radnor, is EPA Zone 1 — the highest radon-risk classification. Testing is essential on every purchase, new construction included.
iv
Complex Mechanical Systems
Larger homes often have multi-zone or multi-generation heating and cooling. We evaluate every system, service entry and electrical panel thoroughly.
v
Stucco & Newer Construction
Later construction and additions sometimes use stucco or EIFS, which rely on proper flashing at windows, rooflines and penetrations.
vi
Wooded Lots & Drainage
Mature trees and sloping lots shade roofs, fill gutters and send water toward foundations. Drainage and sewer laterals get a close look.

The Radnor Main Line standard

At Radnor’s price levels, an unidentified defect is real financial exposure — a slate roof near the end of its life, a failing multi-zone system, moisture behind stucco, or a collapsed sewer lateral under an old tree. Our most senior Delaware County inspectors, led by ASHI Master Inspector Michael Kelley, handle the Main Line’s most significant homes. And because Delaware County is EPA Zone 1, every Radnor inspection should include radon testing.

ii. The services that matter most

What to inspect in Radnor.

Service i.
Home Inspection
A comprehensive evaluation of structure, roof, electrical, plumbing, HVAC, and major systems — the kind of detailed inspection Radnor’s estates and premium homes require — delivered as a photo-rich report the next business day. Condos from $329.
Service ii.
Sewer Scope Inspection
Strongly recommended for Radnor’s older homes and estates, where clay and cast-iron laterals run long distances under mature trees. Our camera travels the full lateral from cleanout to main and documents what it finds.
Service iii.
Radon Testing
Delaware County is EPA Zone 1, the highest radon-risk tier. Our PA DEP-certified technicians use tamper-resistant electronic monitors with 48-hour turnaround. Mitigation, if needed, typically runs $800 to $2,500.
Service iv.
Termite / WDI & Mold Testing
Termite and wood-destroying-insect inspections are required by most lenders, and mold testing is key for older stone basements and any home with signs of moisture. Both can be added in a single visit.

vi. Common questions

Radnor home inspection FAQs.

+
Home inspections start at $429 for a single-family home and $329 for a condo. Final pricing reflects the home’s size and age. Packages save more: Value Package $829 (save $149), Value + Sewer Scope $1,108 (save $199), and Full Protection $1,457 (save up to $249). Get an instant quote online or call (215) 860-3150.
Is radon testing necessary in Radnor, PA?
+
Yes. Delaware County, including Radnor, is EPA Zone 1 — the highest radon-risk classification. Radon levels vary dramatically from house to house, even next door, so testing is the only way to know — and it applies to new construction just as much as older homes. Our DEP-certified technicians use tamper-resistant electronic monitors and deliver results within 48 hours.
What are the most common issues in Radnor homes?
+
Common findings include slate and tile roof repairs, chimney and masonry wear, aging multi-zone HVAC systems and boilers, original wiring and plumbing in older homes, stucco moisture on later construction, basement water on wooded lots, root intrusion in long sewer laterals, and elevated radon. Our home inspectors explain what’s routine for a home of its age and scale versus what’s worth negotiating.
Do I need an inspector experienced with Main Line estates?
+
For Radnor’s larger homes, yes. Estates carry slate and tile roofs, stone masonry, leaded glass, and multi-zone mechanical systems that a general inspector can easily underestimate. Our most senior home inspectors, led by ASHI Master Inspector Michael Kelley, specialize in exactly these properties.
Which neighborhoods do you cover in Radnor Township?
+
All of them — Wayne, St. Davids, Villanova, Rosemont, Garrett Hill and Radnor — plus the rest of the Main Line in Delaware, Montgomery and Chester Counties.
Do I need a sewer scope in Radnor?
+
For older Radnor homes, strongly recommended. Long clay and cast-iron laterals under mature trees are prone to root intrusion, offsets and collapse, and repairs can cost $10,000 to $25,000 or more. A camera scope costs a few hundred dollars and documents the full line before you close.
Can I attend the home inspection?
+
Absolutely — and we encourage it. Our home inspectors walk you through every finding in real time and answer your questions on the spot. Most Radnor inspections run 2.5 to 3.5 hours depending on the size and age of the home.
How quickly can I schedule a home inspection in Radnor?
+
Typically within 1–3 business days, often same-week. We inspect seven days a week and deliver reports by email the next business day — most of the time the same day. For tight contingency windows, call us directly at (215) 860-3150.
