Scranton & Lackawanna County, PA
Trusted Basement Waterproofing in Scranton, PA
We waterproof basements in Scranton, PA, keeping water out of the older homes that make up most of the city, where stone and block foundations are the first to leak when the ground turns wet. More than half of Scranton's houses were built before 1940, and those aging foundations sit in a river valley that gets about 39 inches of rain and heavy winter snowmelt each year.

A wet basement almost always comes down to water pressure. Rain and melting snow saturate the soil around the foundation, the saturated soil presses against the walls, and that pressure drives water through cracks, mortar joints, and the seam where the wall meets the floor. Sealing the surface rarely holds, because the pressure behind it hasn't gone anywhere. We relieve the pressure and give the water a controlled path out.
Our Basement Waterproofing Services in Scranton
Water gets into Scranton basements in a few different ways, so we match the method to where it's coming from and how the foundation is built.
We install interior drainage and sump pumps for water that collects inside at the floor joint. We cut a channel into the slab along the inside of the footing, set a perforated pipe in gravel, and run the whole loop to a sump basin where the pump sends water outside. On block walls, we drill weep holes into the bottom course so water trapped inside the block escapes into the drain instead of pooling behind the wall. This is the least disruptive option, and we can install it year-round. Interior drainage and sump pumps
We waterproof from the outside when water is pushing in from beyond the wall. We open the ground along the foundation down to the footing, clean the wall, and apply a membrane with exterior drainage. It's a bigger job than interior work, but it's the right call when we need to stop the water before it reaches the wall. Exterior basement waterproofing
We repair bowing and cracked walls where soil and water pressure have moved the foundation, often worsened by winters that freeze and thaw the ground again and again. Depending on how far the wall has moved, we seal cracks or install wall anchors or carbon-fiber straps. Basement wall repair
Work is performed by independent professionals. We start every project with an inspection and a written price before any work begins.
Why Scranton Basements Take On Water
Scranton sits in the Lackawanna River valley, and the ground here is a channery silt loam, a soil packed with flat rock fragments. It drains unevenly, so water finds the low path and collects against foundation walls rather than soaking away. With about 39 inches of rain a year plus regular snow, the soil around a Scranton foundation spends long stretches saturated, and saturated soil is what drives water through a wall.
Winter adds a second force. Water that works into a crack or a mortar joint freezes and expands, widening the gap a little, and then the next thaw lets more water in to freeze again. Over a Scranton winter that cycle repeats many times, and older stone and block foundations, with their absorbent mortar joints, give it the most to work on. A hairline crack in November is often a steady leak by spring.
Flash flooding is the sharp end of the problem. In September 2023, heavy rain caused severe localized flooding in Keyser Valley and North Scranton, damaging enough homes that the city later secured federal funding to buy out and demolish the worst-hit properties. Green Ridge has its own long-standing trouble, where an underground creek backs up into basements along Wyoming Avenue, and low parts of Keyser Valley flood almost every time a hard rain comes through. For homes in those pockets, we treat a sump system with a battery backup as a necessity rather than a luxury, because the worst flooding often arrives with the storms most likely to knock the power out.
Mine Subsidence and Older Foundations
Scranton grew up as a coal town, and much of Lackawanna County sits over old underground mine workings. The Pennsylvania DEP maps the areas considered at risk, and standard homeowners insurance usually excludes mine subsidence damage. Subsidence is a separate issue from everyday water intrusion, but both show up as cracks and movement in the same old foundations. If your home sits in a mapped risk area, call 123-456-7890 and we'll walk through what applies before any work starts.
Signs You Need Basement Waterproofing
A wet basement shows up in stages. These are the signs worth watching for in a Scranton home:
- Standing water or damp patches on the floor after rain or snowmelt
- A tide line or staining along the bottom of the walls
- White, chalky residue on the block or concrete, called efflorescence
- A musty smell that lingers even when the basement looks dry
- Cracks in the walls or floor, especially ones that widen over a season
- Walls that bow inward or lean, a sign of soil and water pressure
- Rust on appliances, or warping on anything stored against a wall
One sign on its own is worth watching. Several together mean water is finding a path in, and the sooner we trace it, the smaller the fix.

How We Work
First, we inspect the basement and the foundation, inside and out, to find where the water enters and why. Second, we give you a written plan and a price for the work the home actually needs. Third, our installers carry out the work. Finally, we test the sump and discharge before we sign the job off. Scranton requires a building permit for this kind of structural and foundation work, and the city enforces the 2021 international codes as modified by Pennsylvania's Uniform Construction Code, so we treat permitting as part of doing the job correctly.
What Basement Waterproofing Costs in Scranton
Interior drainage runs less than exterior excavation, and wall repair sits in its own range. Most homes need only one approach. The length of wall we treat, the condition of the foundation, and whether we add a sump and backup all move the number. Any figure online is an average, not a quote, so the only way to know for a specific home is an on-site look. See what affects the price

Frequently Asked Questions
Why does my Scranton basement leak after heavy rain?
Rain and snowmelt saturate the soil around the foundation, and that saturated soil presses water through cracks, mortar joints, and the floor-wall seam. In older Scranton homes, stone and block walls give water the easiest path in. Surface sealers rarely hold because the water pressure behind the wall is still there, so a lasting fix relieves the pressure and routes the water to a sump rather than just coating the surface.
Do I need interior or exterior waterproofing?
Interior drainage suits water that collects inside at the floor joint, and it's less disruptive, costs less, and can go in during any season. Exterior waterproofing is for water pushing in from outside, and it means excavating down to the footing to seal the wall from the outside. Many Scranton homes do well with interior drainage, but an inspection is what settles which the foundation actually needs.
Does homeowners insurance cover a wet basement?
Most policies exclude gradual seepage and groundwater, which is what most wet-basement cases are, and in this area mine subsidence is usually excluded too. Read the specific policy and ask the insurer directly about groundwater and subsidence, because the answer varies from one policy to the next.
Does the work need a permit in Scranton?
Yes. Scranton requires a building permit for foundation and structural waterproofing work, and the city enforces the 2021 codes as modified by Pennsylvania's Uniform Construction Code. Jobs that involve digging out or underpinning a basement also need structural engineering behind the permit. We pull the permit before work starts and post it at the site.
How much does basement waterproofing cost in Scranton?
Interior drainage runs less than exterior excavation, and wall repair sits in its own range. Online figures are averages, not quotes, because the number depends on the method and the size of the basement. The cost guide explains the factors, and an on-site inspection is the only way to get a real number for a specific home.
