Early houses, post-war streets and apartment blocks
Riverdale, a few miles south-west of Greenbelt along Kenilworth Avenue, takes in the town of Riverdale Park and the neighbourhoods around it. Its houses range from early twentieth-century homes on shaded streets to post-war brick houses and large apartment complexes. We connect the people living in all of them with local restoration crews.

Where the water comes from
Age is the biggest factor in the older houses. A century-old home may have galvanised supply lines, cast-iron drains, a clay or cast-iron lateral to the street and several generations of repairs. Joints between old and new materials are common failure points, and a slow drip inside a plaster wall can go unnoticed for a long time.
Older basements take in water from outside. Stone and early block foundations were rarely waterproofed, and in heavy storms or after a long wet spell groundwater can seep through walls and floors, especially where gutters overflow or downspouts discharge right next to the house.
Tree roots are a steady problem. The mature trees that shade Riverdale's older streets also push into sewer laterals, and a partly blocked line can back up through a basement floor drain during heavy use or a heavy rain.
In the apartment complexes, stacked kitchens and bathrooms carry leaks downward, and shared laundry facilities, aging water heaters and toilet supply lines are frequent sources. A tenant downstairs may see the damage long before anyone upstairs knows there is a problem.
Plaster, masonry and old framing all hold moisture, and summer humidity slows drying further. That is why the crew uses dehumidifiers and meters rather than waiting for a wall to feel dry.

Help Me Find the Main ValveRiverdale
Riverdale Park grew up as a railroad suburb, and its older streets still carry houses from the late nineteenth and early twentieth centuries: Victorian-era homes, foursquares and bungalows on generous lots under mature trees. Around them, and in the wider area served by the Riverdale ZIP code, post-war brick houses, duplexes and large apartment complexes fill in the grid between Route 1, Kenilworth Avenue and East-West Highway.
Those two worlds produce different calls. In the older houses, the story is usually about age: plumbing replaced in pieces, plaster walls, stone or block foundations and basements that were never designed to be dry. In the apartment complexes it is about neighbours: stacked units, shared lines and management offices that need to be involved.
A significant share of the area is rented, from apartments to houses let by their owners, and many residents are tenants who need to reach a landlord or manager before work can be approved. We can help with both halves of that conversation.
Whichever kind of building you're in, the restoration team we dispatch starts the same way: find the source, stop it, and take moisture readings to see how far the water has actually travelled.

Usually in the basement, on the wall facing the street, where the water line enters. In some older homes it is hard to reach or stiff with age; if it won't turn, call and we can talk through other options.
Often it is groundwater rather than plumbing. Stone and early block foundations let water through when the soil around them is saturated. Gutters, downspouts and grading make a real difference, and a crew can dry out and document any damage.
Plaster can often be dried in place if it is sound, although it holds moisture longer than drywall. Readings decide whether any sections need to come out.
Tell your management office straight away so they can reach the unit above. Photograph the ceiling and your belongings, move what you can and call if you need a crew.
A lateral partly blocked by roots can back up during heavy use, such as a long laundry cycle. A plumber can clear and inspect the line, and a crew can clean and dry the area it reached.
Yes. The crew can arrange access with your tenants and send you photographs, readings and a work plan to approve.
Usually. Plaster, masonry and old-growth framing hold more water than modern materials, and humid weather slows things further. Equipment stays until readings return to normal.
Often it can be narrowed down with moisture meters and thermal imaging first, so that only the section that needs to be opened is opened.
It's usually better to wait. Carpet and pad are heavy when wet, and pulling them up can damage the floor underneath or spread the water further. If it's safe to be in the room, move small belongings out and leave the carpet for the crew to assess.
