Germantown has old rubble-stone cellars, stone twins and Victorian houses, and the Philadelphia Water Department lists its low-lying parts first among combined-sewer areas where heavy rain backs water into basements. Calls are answered at all hours, and dispatch happens as soon as a crew is available.
Germantown was founded in 1683, and Germantown Avenue is lined with colonial-era stone buildings. Around it are streets of stone twins, Victorian houses and rowhouses in ZIPs 19144 and 19138. Few neighborhoods in the region have housing this old.
Age is the first reason water damage here is its own kind of job. Old cellars with rubble-stone walls, original cast-iron drain stacks and aging galvanized supply lines may be present. These are general patterns, and every house is checked on its own.
Jenkintown Water Damage Restoration works from Jenkintown, in Montgomery County, and the crew handles extraction, drying and tear-out. Waterproofing a stone wall and fixing a drain stack are other trades.
A twin means one party wall and two owners. Water moving through that wall is a shared problem, and the crew often works with both households when a job crosses the line. Dial (833) 490-5225 and describe the room; the crew will give you the safe next steps.
Rubble-stone cellars seep through mortar after long rain.
Low-lying blocks sit on the water department's list for combined-sewer backups.
Stone twins and rowhouses share walls and carry leaks sideways.
A pump that fails in the storm that raises the water table floods the cellar.
Aging galvanized lines fail in winter and at old joints.
Hard freezes in January and February, snowmelt and spring rain on saturated ground, summer thunderstorms and the tropical remnants of late August and September decide which water problems are most likely in Jenkintown from week to week.
The Philadelphia Water Department lists low-lying Germantown first among the combined-sewer areas where heavy rain most often backs water into basements. Combined sewers carry storm runoff and household wastewater together, so a full pipe returns water through the lowest drain in a house.
A cellar floor drain or a basement laundry tub is the usual path. The water is treated as Category 3, so porous materials such as carpet, pad and stored cardboard generally have to be removed.
The department's Basement Backup Protection Program installs free backwater valves for homes that qualify. Applications are at water.phila.gov/basement, and the sewer backup guide explains the program and the safety steps.
Rubble-stone walls are held together with mortar that can break down over many decades. After long rain, water can come through the wall, along the joint between wall and floor and through window wells. Some cellars have a sump pit, and a pump that fails during the same storm turns a seep into a flood.
Stone and plaster dry slowly. Class 4 specialty drying covers dense materials such as these, and the crew checks moisture again after each day of equipment running. Walls that look dry on the surface can hold water for days.
The stone basement water damage page covers the cleanup side and explains what belongs to a waterproofing contractor.
Hillside lots and the stone-twin blocks of Germantown also mean groundwater can enter at the uphill wall, where soil pushes water against the foundation after days of rain. Gutters that dump at the foundation make it worse, and downspout extensions are one of the cheapest fixes an owner can make.
Drain Buddies is a volunteer storm-drain program based in Germantown. The Northeast Times reported in August 2026 that it could be a model for Torresdale, where residents deal with clogged inlets and basement flooding after heavy rain.
The concept is easy to follow. Leaves, dirt and trash clog the city's roughly 72,000 stormwater inlets, and volunteers keep nearby inlets clear so rain drains instead of ponding. It does not replace sewer work, but it can reduce street flooding at a block's low point.
If you want to help your own block, keep the inlet at your corner clear and report ones that look sealed or broken.
Supply lines in houses of this age may be early copper or galvanized steel. Galvanized pipe corrodes from the inside, which narrows it and weakens the walls, and a failure can happen in a joint hidden in plaster. In January 2026 a water main break left about 70 Germantown properties without water, a reminder that the street side is the utility's responsibility.
Inside the house, a burst pipe or a failed fitting is a plumber's repair. The crew handles the soaked plaster, flooring and framing. In twins, water often moves along the shared wall.
Frozen pipes are the winter version. Pipes in exterior stone walls, unheated vestibules and vacant houses freeze first, and a frozen pipe often leaks only when it thaws. If you are away, keep the heat on, open cabinet doors on exterior walls and know where the main shut-off is.

Often, yes. Plaster over lath, stone walls and older paint mean the crew plans around slow drying and around materials that may contain asbestos or lead in homes of this age. Check with your local authority before demolition, and the crew will tell you what it finds.
In an older Germantown house it is usually on the cellar wall where the supply pipe enters, near the meter. Learn where it is before an emergency. If water is coming from a drain, the main will not stop it, so stay clear and call.
No. Drain Buddies is a separate volunteer storm-drain program in Germantown. It is mentioned here because local reports describe it. The crew deals with water inside a house after it gets in, not with street inlets, which are the city's responsibility.
Not always. A pump moves water out of a pit, but it can fail from a power outage or age, usually during the same storm that raises the water table. A water backup and sump discharge endorsement may cover overflow, depending on your policy.
Cost guides for Philadelphia report about $1,597 to $5,456 for a typical water damage job, with a published average near $3,527. Those figures are not quotes. A stone-cellar job with slow-drying plaster and masonry can run longer, and the price is confirmed on site.
