On the evening of July 28, 2026, torrential rain — at times two to three inches an hour — swept eastern Pennsylvania, and flash flood warnings covered Lehigh and Northampton counties, from Allentown through Bethlehem and Easton. The creeks that thread the valley — the Little Lehigh, Jordan, Monocacy, and Bushkill — rose fast, and a lot of that water ended up in basements. If your home took on water, here's the honest version of what to do next: dry everything within 24–48 hours, document it, and don't sign a big remediation contract while you're still wet and stressed. Many homes that dry out fast need no professional remediation at all.
Allentown, Bethlehem, and Easton are rowhome and twin country — brick homes from the cement-and-steel era, many over a century old, with stone or block foundations and low cellars that were never meant to be living space. Water seeps in through old mortar joints and floor seams and then just sits in the cool, still air down there, outlasting the storm by days. If your basement took on water: get it out fast with a wet/dry vac or a pump, pull carpet pad and cardboard boxes off the floor the same day, and run a dehumidifier hard for several days — not hours — emptying it or draining it to a floor drain. A week later, trust your nose. A sour or musty smell downstairs means moisture is still trapped somewhere, often behind the lower foot of drywall in a finished basement or inside stored belongings. That's usually a bounded fix, not a whole-house job; our cost guide shows what fair prices look like. If your sump pump ran continuously or lost power during the storm, check that it's still working before the next rain.
If you rent, two things are true at once. Your landlord is generally responsible for keeping the home habitable — Pennsylvania courts recognize an implied warranty of habitability in every residential lease, so water intrusion and the dampness that follows are generally the owner's to fix once you give notice. And your own belongings are generally your responsibility (renters insurance may help). Send that notice in writing today, keep the dated photos from step 4, and see our renters guide for what to say and how the process works.
Standing water you can't remove, sewage backup, a large soaked area, or water inside walls, ceilings, or a flooded finished basement. Acting fast is almost always cheaper than the mold that follows.
Water got in but you've removed it and drying is underway. Watch for musty smells or stains over the next week, and test only if a question remains.
A small amount of water, fully dried within a day, on hard non-porous surfaces. Keep it dry and ventilated — you very likely don't need to spend a dime.
After a widely reported flood, door-knockers and urgent phone pitches follow. Some are fine; some are not. The honest rule: no reputable company needs you to sign tonight. Get the water out first, take your photos, and compare at least two quotes for anything over a few hundred dollars. Our cost guide shows what mold and water-damage work typically costs, so you can spot a scare-quote when you see one.
It depends on how the water got in. Standard homeowners policies often exclude rising surface water — that's typically a separate flood policy, like NFIP, and many Lehigh Valley homes outside the mapped creek floodplains don't carry one, so don't assume you have coverage either way. Water seeping through a foundation wall is often excluded too, while sewer or drain backup usually needs its own rider, worth checking in the older rowhome blocks with combined sewers. This is exactly why the dated photos in step 4 matter. Your insurer makes the coverage call, not us — call them early and ask directly.
Mold can begin growing on damp materials within about 24–48 hours. The priority right now is drying — get standing water out, move air across wet surfaces, and run a dehumidifier. Speed matters more than testing in the first two days.
Not necessarily. Hard surfaces and materials dried fully within about 48 hours can often be saved. Carpet padding, drywall that wicked water up from the floor, and finished-basement materials that stayed wet longer frequently do need to come out, because they hold moisture inside. Get the water out, start drying immediately, and get an honest read before committing to a big tear-out.
Pennsylvania recognizes an implied warranty of habitability in every residential lease, so water intrusion and the dampness that follows are generally the owner's responsibility once you give notice. Notify your landlord in writing right away, keep dated photos, and keep copies of everything. Your own belongings are typically your responsibility — renters insurance may help.
