Surface water through window wells and doors
Rain that overwhelms a well or runs down a driveway toward a door brings in soil and debris as well. It is treated as gray water at best and as Category 3 if it came from a creek or storm drain.
Pumping, cleanup and drying when water arrives in a basement from the surface, a failed pump or a backed-up drain.

Basement flooding cleanup in Jenkintown covers water that arrives in volume: surface runoff, a failed pump or a backed-up floor drain. The crew pumps it out, removes wet pad, drywall and stored items that cannot be saved, and dries walls and slab. A person answers at all hours, and a crew is sent as soon as one is free.
A flooded basement is an ordinary job in this part of Montgomery County, not a freak event. Full cellars are the norm in the older twins, rowhouses and mid-century houses around Jenkintown, and the area gets about 44 inches of rain in a typical year. When a cloudburst or a week of wet weather arrives, the water has plenty of places to find a way in.
What matters first is where the water is coming from, because that decides how it is handled. Water that comes in through a window well or over a threshold from the surface is one kind of problem. Water that comes up through a floor drain is another, and it should be treated as contaminated. Water that appears because a sump pump quit is a third, and it often arrives together with a power cut.
This page covers the cleanup of all three. Walls that seep through old stone have their own page, and so do pump failures, so this one stays with the work of getting the water out and the room dry again.
Do not enter water that is near the electrical panel or that covers outlets, and do not use the furnace or water heater if they were submerged. Treat water from a drain as contaminated: no bare skin, no children, no pets.
The crew checks whether water is near the panel, outlets, the furnace or the water heater. If the water is deep or electrical equipment is under it, the power is dealt with first and nobody walks in.
Rain that came through a window well is different from water that came up a drain. The crew records which one it was, because contaminated water changes what can be kept.
Submersible pumps lower the water in stages, and an extractor handles carpet and the slab once the level drops. If the water is still arriving, the crew explains what that means for timing.
Soaked carpet pad, insulation, the lower stretch of finished drywall and stored cardboard are often removed. Hard items such as solid wood furniture and metal shelving can usually be cleaned and kept.
Surfaces are cleaned, an antimicrobial is applied where it is warranted, and air movers and dehumidifiers run with readings every day. A stone or block wall and a concrete slab are slow to give up water, so they get the most checking.
Drywall, trim and flooring are quoted after the cellar is dry. Hanging new drywall early traps moisture against the framing.
Cost guides for the Philadelphia area report basement cleanup in a broad band, and category matters most. Clean water is the cheapest to deal with and sewage the most expensive.
| Job | Typical range | What it includes |
|---|---|---|
| Flooded basement cleanup, typical total, per cost guides | $2,000–$7,000 | Guides report an average near $4,000, or about $3 to $7 per sq ft |
| Clean water (Category 1) total, as roundups report | $1,500–$3,500 | Groundwater or a line, caught early |
| Gray water (Category 2) total, as roundups report | $3,000–$7,000 | Surface runoff, washer discharge |
| Black water (Category 3) total, as roundups report | $7,000–$15,000 | Sewage or creek water |
| Carpet pad removal and disposal, per sq ft | $0.75–$2.00 | Working estimate |
| Antimicrobial application, per sq ft | $0.50–$2.00 | Working estimate |
Treat the totals as what published roundups say and the last two rows as a working estimate for Montgomery County in 2026. None of it is a quote: the crew prices the job once it has seen the water, and you approve the emergency stage first.
Short, intense storms overload window wells, drains and storm inlets faster than they can empty, and old combined sewers can fill beyond capacity. Heavy ground water pressing on a cellar wall and slab adds to it. Leaf-clogged inlets and repaving that raised streets above curb drains make local flooding worse.
Rain that once soaked into lawns now hits roofs, driveways and pavement and runs fast toward the low spots. Jenkintown Creek, which feeds the Tookany system, drains a watershed that WHYY says is about 98 percent developed, so runoff reaches the creek and the streets quickly.
August 2026 is a recent example. After sixteen straight months of below-normal rain, ordinary storms flooded basements across Philadelphia, and residents in places such as West Mount Airy said nearby roads become a river.
Non-porous items such as metal shelving, solid wood furniture, glass and plastic bins can usually be cleaned and kept. Carpet pad, insulation, particleboard, drywall wet above a few inches and anything soaked in contaminated water are normally removed. The crew lists what it removes and you approve it.
Photograph the cellar before anyone moves anything. Items on the floor go first, because boxes act like wicks and carry water up into what is stored in them.
Furnaces and water heaters that stood in water should be checked by a licensed technician before they are restarted, which is outside what the crew does.
Mold can start growing on wet materials within a day or two, so the EPA advises drying water-damaged areas and items within 24 to 48 hours. A cellar that stays damp through a humid summer is at more risk. If mold is already visible, a crew can assess it before it spreads.
A moldy patch smaller than about 10 square feet can usually be cleaned by a homeowner, according to the EPA. Larger areas, sewage-related mold or mold in a heating system call for professional help.
The mold inspection page explains what an assessment includes and how to choose someone to do it.
It depends on how the water got in. Standard homeowners policies exclude flood from surface water, and sewer or drain backup is typically covered only with an endorsement. A water backup and sump discharge endorsement can cover backup and sump overflow. Whether the loss is covered is the insurer's call under the policy, so talk to your agent.
Flood insurance is a separate policy from the National Flood Insurance Program or a private insurer, and it generally takes 30 days to take effect, so it cannot be bought after a storm is on the way.
Take photos, keep receipts and call your insurer early. The crew provides readings, photographs and a list of removed materials, but it cannot promise the outcome.
Rain that overwhelms a well or runs down a driveway toward a door brings in soil and debris as well. It is treated as gray water at best and as Category 3 if it came from a creek or storm drain.
Water coming up a drain has passed through the sewer, so it is treated as contaminated. Porous materials that it touched usually have to go, and the cleanup follows the sewage cleanup approach.
If the pit overflowed because a pump quit, the water is usually groundwater and relatively clean at first. It still carries soil and may become gray as it sits. The sump pump failure page covers the pump side.
In Jenkintown and the neighboring townships, a flooded basement is usually a story about slope and saturated ground. Houses in the borough sit near Jenkintown Creek and the Tookany system, and Montgomery County planners have named Abington and Cheltenham among the places that have taken flood damage along Tookany Creek.
The cellars themselves vary: stone and block walls in the older twins, brick in the rowhouses and poured concrete in later houses. All of them have window wells, floor drains and a sump pit as the three places water arrives.
The Philadelphia Water Department's basement backup program covers homes inside the city. Outside it, ask your borough or township about sewer connections, and check your policy before a storm.
A crew is dispatched as fast as one is available, and you approve the estimate before any work starts.

Cleanup and drying after a sump pump fails, with the pump itself repaired or replaced by a plumber or pump contractor.
Cleanup and drying for older cellars where water weeps through the face of rubble stone walls rather than through a crack.
Removal, cleaning and drying after sewage or a sewer backup reaches a basement, handled as Category 3 contamination.
Monitored drying of plaster-and-lath walls, hardwood over joists and stone or brick, with daily readings until dry.
Cost guides report a typical water damage restoration job at $1,383 to $6,369 nationally (HomeAdvisor, average about $3,868) and $1,597 to $5,456 for Philadelphia (Angi, average about $3,527).
It depends on the cause and on your own policy, and only your insurer can say.
Old rubble-stone and brick cellar walls seep because they are porous masonry in soft mortar, set in ground that fills with water after long rain.
A sewer backup pushes wastewater up through a floor drain, toilet or basement fixture, and it is Category 3 water.
On September 1, 2021, the remnants of Hurricane Ida dropped roughly 5 to 10 inches of rain on eastern Pennsylvania, most of it in a little over six hours.
Pumping usually takes hours, and drying takes several days, longer for stone, block and concrete. Repairs begin once readings show the structure is dry. The crew checks daily so you know where the job stands.
Not if it came from a drain, a creek or a storm inlet. Treat that water as contaminated and keep skin and children out. Groundwater from a failed pump is cleaner at first but picks up contamination as it sits.
Carpet that sat in clean water briefly can sometimes be extracted and dried, but the pad usually cannot. Carpet soaked by contaminated water is normally removed. The crew explains each case and you decide.
A household dehumidifier can help with light dampness, but it will not dry a soaked cellar. Commercial units, air movers and daily readings are how a crew proves the structure is dry.
It depends on rain intensity, how saturated the ground already was, and whether your pump, window wells and drains kept up. Heavy rain on wet ground is worse than the same rain after a dry stretch.
No. Cleanup and drying are the work. Waterproofing, grading, drain tile and pump installation are other trades, and a good crew will tell you which one to call once the cellar is dry.
