Nine communities across the county have a page of their own with local detail. The packages, the prices and the laboratory are the same in every one of them, so you can also book straight from here.
Brick duplexes and postwar garden apartments sit on tight lots just inside the District line, built up over several different decades.
Older farmhouses and brick foursquares sit near postwar duplexes and garden apartments crowded against newer commercial development along the Beltway.
Frame cottages from the original crossroads sit near brick garden apartments built up around the federal government's midcentury expansion.
Campus rentals near the university share streets with older bungalows and later brick houses built during the college town's biggest growth years.
Cooperative rowhouses from the town's earliest section sit near garden apartments and newer condominium towers closer to the Metro station.
Older farmhouses on well and septic near the original crossroads sit close to newer subdivisions built out along Woodyard Road.
Walkout lower levels above the golf course sit near older farmhouses close to the creek and newer construction closer to the Beltway.
Bowie, College Park, Greenbelt and Laurel are incorporated cities inside the county; Chillum, Clinton, Fort Washington, Landover and Suitland are unincorporated communities known by their postal names. The same team, packages and prices cover all of them.
Four options, depending on how much of the home you need looked at. Not sure which one fits? Start with the thirty minute visit and a technician will tell you what is actually worth testing. Decide to test while they are there and the visit is written up as a Mold Plus.

Prince George's County built outward from the District line. Chillum, Landover and Suitland filled in first, followed by the university town of College Park and the planned community of Greenbelt along the Route 1 and Beltway corridors. Bowie and Laurel grew up around older rail and mill settlements before spreading into newer subdivisions to the north and east. Clinton and Fort Washington, toward the county's southern reach, still mix old farm crossroads with newer construction. A booking anywhere in the county starts with the house's age and where the water already runs.
The county's own soil conservation district lists the Christiana soil complexes and the Marlboro Clay formation among the ground with severe limitations for foundation work, and warns against letting water pond above that clay because it can speed slope failure. Both are widespread across the county, not confined to one community. On that ground, a finished basement, a crawlspace under a rambler, or a townhouse party wall gets the closest look, along with the grading beside the foundation and whether a sump pit has kept up during heavy rain.
Local background: Prince George's Soil Conservation District: Soil Erosion and Sediment Control Reference Manual (2013).

01
The county's soil conservation district lists the Christiana complexes and the Marlboro Clay formation among the ground with the most severe limitations for foundation work, and it runs through many parts of the county rather than one corner of it. Cracked slabs, sticking doors and a foundation wall that has visibly shifted are the pattern on that ground, and the report notes which rooms actually tested positive rather than assuming the whole house did.
02
Chillum, Landover and Suitland sit inside the Anacostia River's headwaters, where older storm drains and narrow floodplains keep some yards wet well after a normal rain. A downspout that empties two feet from the foundation or a window well that fills during a storm gets photographed as part of the visit, and the report notes the grading exactly as it was found.
03
College Park, Greenbelt, Suitland and Landover all carry garden apartment buildings built up around the Metro corridors that reach into the District. A leak on an upper floor can travel through a shared chase to a unit below, so samples are taken on both floors when the stain does not match the unit's own plumbing.
We do not remove mold, so we have nothing to gain from your results. If your report shows a problem, you choose who fixes it. Once the work is done, we can test again and tell you what we find.
For a Maryland property, define the question before ordering samples: a particular stain, persistent odor, water event or follow-up after repairs. Keep dated observations and laboratory findings with the repair history. A report does not determine health risks, insurance coverage or legal responsibility. Montgomery County also publishes separate radon requirements for covered home sales; confirm which rules apply to your transaction.

Yes. The same team and pricing structure book across the whole county, from the communities inside the Beltway to Bowie, Laurel and the southern reach toward Clinton and Fort Washington. Each community page adds detail specific to that place, and a booking can start from any of them.
No. Places such as Chillum, Landover and Suitland are unincorporated and often carry a postal city name that is not their own, while Bowie, College Park, Greenbelt and Laurel are incorporated towns with their own local government. Give us the full street address when you book, and the report reflects the correct jurisdiction regardless of what the mailing label says.
Not automatically. An older house near an original crossroads or rail stop may carry more additions and repairs, which changes what a technician needs to see, but a newer subdivision house can have its own grading or plumbing problems. The visit is built around the specific room and history described at booking, not the decade the house was built.
Actual openings for a specific date and time are visible on the booking calendar for every community listed here. If the house is part of a pending sale, mention that timeline in the booking notes so the visit and the lab work can be scheduled around it.
