Lanham, MD water damage restoration for split-levels, ramblers and Cape Cods

Lanham at a glance

Lanham is in central Prince George's County, where US 50 crosses the Beltway, with Greenbelt and College Park to the north-west, Riverdale to the west and Bowie to the east. Annapolis Road and Lanham-Severn Road carry most of the local traffic, and the Seabrook area around its MARC station sits on the north side. It's mostly residential, with shopping along the main roads and quiet streets branching off them.

Most of the housing went up in the decades after the Second World War. Brick and frame ramblers, Cape Cods and split-levels line many streets, with colonials, townhouse communities and garden apartments added later. Nearly every detached house has a basement or a lower level partly below grade, and many were finished by owners over the years with paneling, carpet and a drop ceiling, or later with drywall and bathrooms.

That lower level is where most water damage here ends up. A split-level's family room sits a few feet below the yard, with windows in wells at ground level and soil against two or three walls. The water heater and laundry are usually nearby. Water from outside, from a failed sump or from a tired fitting all reaches it first, and carpet over pad hides it well.

Lanham is served by public water and sewer. The land is gently rolling, with streams draining toward the Anacostia's northern branches, and the soils hold enough clay to keep water against foundations after long rains. Mature trees planted when the neighborhoods were new now fill gutters every autumn, and summer storms that stall over the area can overwhelm downspouts that empty beside the house.

Many homes of the same age are now reaching the point where original sump pumps, water heaters, washer hoses and supply lines wear out together. Some owners also rent out a basement unit or the whole house, which adds a tenant to the first call. Knowing whether water is coming from outside or from the plumbing is the first thing that decides the fix.

Before: seepage, plumbing leak or condensation?

Water in a lower level arrives from one of three directions, and each has a different fix. Seepage comes from outside through the foundation. It shows up hours or a day after rain, along the base of an exterior wall or at the joint between wall and floor, often leaving a white mineral crust called efflorescence on block or concrete, and it dries out between storms. On a split-level, the walls with the most soil against them show it first.

A plumbing leak follows no weather pattern. It sits near a pipe, the water heater, the washer or a bathroom above, grows steadily, and makes the water meter's leak indicator move even when every tap is off. Condensation is the third possibility in humid Lanham summers: cold-water pipes and cool walls sweat, and the carpet beneath them stays damp.

A few checks sort them out. Tape a square of plastic to the wall for a day: moisture on the room side points to condensation, behind it to seepage. Read the meter before and after an hour with no water in use. Note when the dampness appears. Drying is similar for all three, but the lasting fix is not: a plumber for leaks, grading or waterproofing for seepage, a dehumidifier for condensation.

During: when the sump pump quits in a storm

Many Lanham basements have a sump pit, where drain tile around the foundation collects groundwater and a pump sends it out to the yard. In a long summer storm the pump may cycle every minute or two for hours, and that's exactly when it tends to fail. The float catches on the pit wall and never switches on. An old motor finally stops. A worn check valve lets each discharge fall back in. Or the storm that fills the pit also cuts the power.

If it happens, stay out of any water near outlets or the electrical panel and call your utility. Otherwise, get power back or a working pump in the pit, move what you can off the floor, and photograph everything. A wet-vac helps with clean water on hard floors. Then call so drying can start before the pad and drywall soak through.

Afterward, set up the routine that prevents a repeat: a bucket of water poured into the pit each spring to test the pump, a clean pit, a discharge that empties several feet from the house, a battery backup pump and a high-water alarm. In winter, check that the discharge line's outdoor end hasn't frozen shut.

After: drying a finished lower level

Once the water stops, the finished lower level is where the work is. Carpet sits on pad over the slab, and paneling or drywall runs down to a bottom plate on the concrete. Water spreads under the pad and wicks up the wall well beyond what shows on the surface, so the crew maps the wet area with moisture readings before deciding anything. By the time a baseboard swells, the wall behind it has often been wet for days.

Below grade, drying takes longer than upstairs. The slab releases moisture slowly and cool basement air holds humidity, so dehumidifiers do most of the work. The usual results: pad comes out, carpet can sometimes be lifted, dried and relaid, and drywall or paneling is removed a little above the highest wet reading so the cavity behind it can dry. Built-in shelving may need to come off the wall.

The job ends when readings in the slab, framing and remaining walls match dry areas of the house, not on a set date. After that, a water sensor beside the heater and the laundry, and a meter check when the bill jumps, catch the next slow leak early.
