Main Line Home Inspections.

A Main Line home inspection protects one of the largest purchases you will ever make — and the home inspector you choose decides how much it is worth. ValueGuard provides expert home inspections across Philadelphia’s Main Line, from Overbrook to Malvern. The Main Line is where Philadelphia’s housing history reaches its grandest. Running west from the city through Montgomery, Delaware and Chester Counties, it strings together a century-and-a-half of architecture — slate-roofed stone estates, gabled Tudors, gracious center-hall colonials, and the new construction now rising between them. That range is exactly what makes a Main Line home so rewarding to own and so easy to mis-inspect. Knob-and-tube wiring, plaster walls, stone foundations, oil-to-gas conversions, slate and tile roofs, carriage houses, pools, and additions layered over decades all turn up here — and our ASHI-certified home inspectors know precisely what each one is hiding.

Inspections from $399 — condos from $299. Larger estates are priced by size, age and services. Save with a package:

A century of craftsmanship

The grandest homes on the Main Line hold a century of secrets. We find them before you sign.

i. The towns along the line

Every stop, end to end.

The Main Line takes its name from the old Pennsylvania Railroad — sixteen communities strung west from Philadelphia across three counties. Choose your town for local inspection detail and recent ValueGuard work in your neighborhood.

ii. Why the Main Line is different

A century-old estate deserves a finer home inspection.

Main Line homes are extraordinary — and extraordinarily specific. A generic home inspector’s checklist misses what matters when a house has stood for a hundred years. Here’s where our 94,000 inspections pay off:

What Main Line homes hide, by era.

Knowing what each generation of construction tends to conceal is where decades of local experience earn their keep.

Slate, stone, and a hundred winters.
The slate roofs, masonry, and chimneys that define Main Line architecture reward a careful, experienced read. When a roof can’t be safely walked, our inspectors use drones to document it in detail — so nothing gets overlooked.

iii. From our recent caseload

No. 01

Bryn Mawr
Stone Tudor Estate
A grand fieldstone Tudor with a slate roof, conical corner turret, decorative half-timbered gable, and a Gothic-arched leaded-glass entry. Original masonry, slate, and decades of additions all need an inspector who knows where age hides.

No. 02

Villanova
Brick Center-Hall Colonial
A gracious brick colonial with black shutters, a columned front portico, and a light-filled conservatory wing. Behind the refined facade sit the systems, windows, and roofline that a home of this stature deserves to have read carefully.

No. 03

Wayne
Newer Stone & Clapboard Build
A recently built stone-and-clapboard home with a steep gabled roofline, copper accent awnings, and a paver motor court. Even newer construction connects to older municipal infrastructure — and benefits from an independent, experienced eye before closing.

No. 04

Haverford
Slate-Roofed Tudor Estate
A sweeping Haverford estate with an expansive slate roof, half-timbered gables, multiple chimneys, and a flagstone courtyard. On a home like this the roof alone takes time to assess properly — which is where drone documentation earns its keep.

Malvern
Stone Colonial with Carriage House
An established Chester County estate — a stone-front colonial with an attached carriage-house wing, cupola, and circular drive. Generous grounds and outbuildings like these are exactly what reward a thorough, unhurried inspection.

No. 06

Gladwyne
Gray Stone Manor
A castle-like Gladwyne manor with twin stone towers, a Gothic-arched entry, arched carriage bays, and a mix of flat and slate roofing. An estate of this scale and complexity is exactly where 94,000 inspections pay off.
