More than half of Newington’s homes are townhouses, most of them built around 1980, give or take a decade, and in a lot of them the laundry sits on the bottom floor. The dryer vent goes straight out the back wall a few feet above the grass. A short run is the good news. The catch is where it comes out: often under the back deck, where leaves, lint and the odd nest collect around the hood and nobody sees them until the flap stops opening.
Laurel Hill flips that around. About six in ten of its homes went up after 2000, and a lot of houses from those years put the laundry room on the bedroom floor. From there the dryer vent has to cross between ceiling joists to an outside wall or climb to the roof, often with two or three elbows on the way. Lint drops out at every turn, and none of them can be seen from the laundry room.
Better than eight in ten Laurel Hill owners heat with gas, and where a house has gas the dryer often runs on it too. A gas dryer pushes its combustion gases out through that same lint-lined pipe, so a packed run or a connector crushed flat behind the machine matters more on one than on an electric. Pull the dryer out now and then and look: the connector should be metal, short, and not squashed against the wall.
Lorton’s middle Census place has a quarter of its homes in condos and apartments, and over a third of them are rented. Where the building has shared walls, the dryer vent may climb through them to the roof, and the association documents say whose line it is. Where the unit is rented, the landlord tends to schedule the dryer vent cleaning, and our dated invoice and camera photos go in the file for the next lease.
