Halethorpe, MD water damage restoration for rowhouses, duplexes and rentals

Shared walls in Halethorpe rowhouses and duplexes

A large part of the housing around Halethorpe, Arbutus and Lansdowne is attached: brick rowhouses in groups, duplexes sharing a center wall, and townhouse rows. Those party walls are solid masonry in older homes and framed fire walls in newer ones, and water that reaches their base keeps going. It follows joists that rest on the wall, travels along the joint between wall and basement floor, and can wick into brick.

A leak in one home's kitchen or basement laundry can show up as wet carpet or a stain next door, sometimes before anyone at the source notices. Basements in attached homes also tend to have floor drains close to the shared wall and sewer connections that run near each other to the street.

After a leak near a party wall, readings on both sides show whether the neighbor's home is affected, and drying may need access to both. Tell the neighbor early, and if either home is rented, tell both landlords. On low-slope rowhouse roofs, one blocked gutter or scupper can push water under the flashing of the house beside it.

Halethorpe at a glance

Halethorpe is in south-western Baltimore County, just outside the city line, sharing ZIP code 21227 with Arbutus and Lansdowne. Catonsville and the UMBC campus area lie to the west, Linthicum Heights and the airport to the south-east across the Patapsco, and Elkridge to the south-west beyond the river valley. I-95, I-695 and Southwestern Boulevard cross the area, and the Halethorpe station serves the MARC line to Baltimore and Washington. Patapsco Valley State Park borders much of the area along the river.

Housing is a mix. There are brick rowhouses and duplexes, many from the decades around the middle of the twentieth century, blocks of small detached homes, some older frame houses near Relay dating from before the Second World War, and townhouse and apartment communities. Nearly all have a basement, often with the water heater, laundry and a floor drain close together, and many basements have been finished with carpet and paneling.

A good share of homes are rented, and landlords often own several properties in the area. So calls come from tenants, owners and small landlords alike, and more than one person usually needs to hear about a leak.

Owners and tenants here tend to be practical about water, and many basements have seen a wet spring or a slow drain before. What changes the outcome is how quickly the source is found and stopped, whether the neighbor is told, and whether wet carpet and paneling are pulled back before they soak for days. Those three things matter more than anything else.

The area is on public water and sewer. The ground slopes toward the Patapsco valley, and on those slopes some basement walls sit against wet soil after long rains. Older homes may still have original angle stops, galvanized or early copper supply lines, and cast-iron drains. Mature street trees fill gutters every autumn, and summer thunderstorms can overwhelm downspouts that empty right beside the foundation.

Winters bring cold snaps that reach pipes along rear walls, over porches and in additions. In attached homes, the end unit of a row has more exterior wall than the others, which means more exposure to both wind-driven rain and cold.

A damp basement wall: seepage, plumbing or condensation?

Basement water comes from outside through the foundation, from inside through plumbing, or out of the air as condensation, and each has its own fix. Seepage shows up hours or a day after rain, along the base of an exterior wall or at the floor joint, often leaving a white mineral crust called efflorescence, and it dries between storms.

In humid Halethorpe summers, condensation fools plenty of people: cold-water lines and cool walls sweat and the floor below stays damp. A square of plastic taped to the wall for a day helps: moisture on the room side means condensation, behind it means seepage. Drying is similar for all three, but the cure differs: a plumber for leaks, grading or waterproofing for seepage, a dehumidifier for condensation. Note when the dampness appears and how far it spreads; the pattern tells a crew more than a single look. In an attached home, check the shared wall too, since water from next door can look like seepage.

Supply lines, angle stops and appliance hookups

Many of the leaks that cause the most damage start at a fitting smaller than a thumb. Braided supply lines to toilets and sinks, the small shutoffs under fixtures called angle stops, washing machine hoses, dishwasher lines and refrigerator ice-maker tubing all wear out. Rubber hoses harden and split. Braided lines corrode where the braid meets the crimp. Old multi-turn angle stops seize open, or drip at the stem when finally turned.

Because these connections are under constant pressure, a failure keeps running until someone notices or closes a valve. A split washer hose in a basement laundry can put a lot of water on the floor in an hour, and in a rowhouse that water may reach the neighbor's side before it's found. Refrigerator ice-maker lines crack when the fridge is pushed back after cleaning, and dishwasher supply lines under the counter wear out unseen.

The fixes are inexpensive: braided washer hoses replaced every several years, new supply lines when a fixture is serviced, quarter-turn valves in place of seized angle stops, and a pan or water sensor under the washer and heater. Landlords can build these into turnover checks, and tenants should know where the main is from the first day. Knowing where the main shutoff is, and that it turns, matters most.
