Montgomery County is where Greater Philadelphia’s housing history is on full display. Since 1997, ValueGuard has completed over 94,000 home inspections across the region — more than any other inspection company. Montgomery County spans the storied Main Line, the rolling northern townships, and fast-growing suburban corridors, packing colonial farmhouses, Victorian-era homes, mid-century ranchers, slate-roofed estates, and brand-new construction into a single county. That range means knob-and-tube wiring, stone foundations, plaster walls, oil-to-gas conversions, well-and-septic systems, and aging sewer laterals all turn up here — and our ASHI-certified inspectors know exactly what to look for in each.

i. Why this county is different
Montgomery County demands a different inspector.
Main Line estates, stone foundations, slate roofs, the highest radon risk in the country, and outer-township well-and-septic systems. Generic inspectors miss what matters in Montgomery County. Here’s what we focus on:
Main Line Estate Homes
Bryn Mawr, Haverford, Ardmore, and Wynnewood hold some of the region’s oldest and most complex homes — knob-and-tube wiring, slate and tile roofs, plaster walls, and stone foundations that demand experienced eyes. We know these properties intimately.
Highest Radon Risk in the Country
Montgomery County is EPA Zone 1 — the highest radon classification. Nearly one in three homes tests above the EPA’s 4 pCi/L action level. Our DEP-certified technicians run 48-hour electronic tests with tamper-resistant monitors.
Stone Foundations & Moisture
The county’s older housing stock — stone foundations, finished basements, and aging HVAC — is prone to moisture intrusion and mold. We identify problem areas and recommend the right testing before you close.
Well, Septic & Oil in the Townships
Outer communities like Skippack, Schwenksville, and Limerick often have private wells, septic systems, and oil heat. We know the questions these systems raise — and how oil-to-gas conversions and abandoned tanks can surprise a buyer.
Aging Sewer Laterals
Pre-war and mid-century homes from Norristown to Conshohocken to the Main Line sit on aging clay and cast iron sewer laterals. A camera inspection before closing is the only way to know the true condition of the line beneath the yard.
A Fast, Competitive Market
Blue Bell, Lansdale, Horsham, and Collegeville are among the most active markets in Greater Philadelphia. Same-week scheduling and next-business-day reports mean your inspection never becomes the bottleneck on a deal. Seven days a week.

The Montgomery County Radon Warning
Montgomery County is EPA Zone 1 — the highest radon risk classification in the country. Nearly one in three homes here tests above the EPA’s 4 pCi/L action level. Radon is colorless, odorless, and the second leading cause of lung cancer in the United States, 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 Montgomery County home without testing.
From our recent caseload
Recently inspected in Montgomery County.
Six homes from recent ValueGuard inspections across Montgomery County — Main Line estates, stone capes, new-construction farmhouses, and suburban colonials. One county, six entirely different inspections. Swipe or use the arrows to see all six.
No. 01
Main Line Stone Tudor Estate
A sprawling stone Tudor estate with a slate roof, corner turret, and tall chimney stacks — the kind of grand Bryn Mawr property where original masonry, slate, and decades of additions all need an inspector who knows where age hides.
No. 02
Tudor Stone Main Line Estate
A Tudor-revival stone home of the kind that defines Haverford’s quietest streets. Original masonry, vintage systems, and a footprint that takes hours to inspect properly.
No. 03
Historic Stone Colonial
A handsome stone colonial on a mature Glenside lot — the kind of pre-war home where original framing, plaster, and a stone foundation all need a careful, experienced read.
No. 04
Stone Cape Cod
A solid stone cape on a leafy Elkins Park street — charming, well-kept, and exactly the kind of mid-century home where aging systems and a buried sewer lateral deserve a close look.
No. 05
Stone & Vinyl Townhome
A newer stone-and-vinyl townhome in fast-growing Conshohocken. Even recent construction connects to older municipal infrastructure — which is why a sewer scope still earns its place here.
No. 06
New Construction Modern Farmhouse
A brand-new modern farmhouse in one of Lansdale’s growing developments. New construction still needs an independent eye — builder punch lists and warranty inspections catch what gets missed in the rush to close.

ii. The four services that matter most
Four services every Montgomery County buyer needs.
Radon Testing
Montgomery County is EPA Zone 1 — the highest radon risk classification. Nearly one in three homes tests above the EPA’s 4 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
Montgomery County’s older homes — Main Line estates and pre-war properties with wood in contact with soil and aging foundations — create ideal conditions for termites and wood-destroying insects. A certified WDI inspection is required by most lenders.
Mold Testing
Older Montgomery County homes — those with stone foundations, finished basements, and aging plumbing — are prone to moisture intrusion and mold growth. Our certified mold testing covers air sampling and surface testing for a complete picture before you close.
Sewer Scope Inspection
Pre-war and mid-century homes throughout the county — from Norristown to Conshohocken to the Main Line — sit on aging clay and cast iron sewer laterals. A camera inspection before closing is the only way to know the true condition of the buried line.

My experience with Michael Kelley exceeded my expectations. Knowledgeable, informative, and very thorough. I chose ValueGuard because they inspected my property 20 years ago — so why not call them back for my pre-listing.
