Pressure Washing in Swarthmore, PA
Power washing and soft washing for Swarthmore’s Victorians and 1920s stone colonials under an unusually heavy tree canopy.

Swarthmore has some of the heaviest tree cover in the county: the college campus is an arboretum, and the streets around it sit under mature canopy. That makes it one of the hardest places in Delco to keep algae off a house, and one where a clean exterior needs looking after more often.
Permanent shade changes the whole calculation
Under continuous canopy a surface never fully dries out. Algae does not just arrive, it lives there, and a rinse-only clean will be green again inside a couple of months. The only approach that holds here is chemistry that kills the growth at the root, and even then a shaded Swarthmore walkway greens up sooner than the same slab on an open, sunny street.
Leaf tannin is the other half of it
Wet leaves left on concrete leach tannin and print a brown shadow into the slab - it is a stain rather than a film, and it does not lift with pressure alone. It responds to the right treatment, and it is worth clearing leaves off flatwork in the fall rather than letting them sit through the winter.
Victorian wood and 1920s stone
Swarthmore's houses split between painted Victorian wood and 1920s stone, often on the same street. Painted clapboard and porch trim need a soft wash and hand work, and stone needs a mortar-first approach. Both sit in shade for much of the day, which is why both grow algae quickly here.
Moss on steps and walks
Stone steps and brick or concrete walks under heavy shade grow moss in their joints and a slick film on top. Cleaning takes both off and makes the steps safer in wet weather. Joints that have lost their fill grow back faster, and we will point those out.
A walking town's front steps
Swarthmore is a walking town, with the station, the shops and the campus close together, and front walks and steps see a lot of feet. Shaded walks grow a slick film that is easy to miss until it is wet. Cleaning them is one of the simplest ways to make a front entry look cared for and feel safer, and it pairs naturally with a house wash.

Swarthmore grew around its college. Quakers founded Swarthmore College in 1864, passenger trains from Philadelphia made the town a commuter suburb in the 1880s, and the borough was incorporated in 1893. It was first called Westdale, after the painter Benjamin West, who was born there, and many streets in its southern half are named for eastern colleges.
Much of the housing dates from the Victorian period through the 1920s. About a third of the borough is the college campus, which is also the Scott Arboretum and runs west into the Crum Woods, and Crum Creek forms the borough's western boundary.
The name goes back to Swarthmoor Hall in England, where the earliest meetings of what became the Religious Society of Friends were held. Today the borough covers about a square mile and a half, and it is known for its tree-lined streets.
Swarthmore sits between Wallingford across Crum Creek to the west, Springfield to the northeast and Ridley to the south. Its train station on the Media/Wawa Line is at the foot of the campus, and Chester Road runs through the borough. The borough is compact and a short drive from our base in Lansdowne. That makes a spring house wash and a fall cleaning of the walks easy to plan here, which suits a town with this much shade.
