Standing water in a small East Lansdowne yard isn’t just an eyesore. When water sits within ten feet of a foundation that’s been there since the 1920s or 1930s, it builds pressure. That pressure leads to basement seepage, foundation cracks, and damage to the kind of original woodwork and architectural detail you can’t just replace at a hardware store.
The density of East Lansdowne makes the problem worse than it looks on the surface. With over 13,000 residents per square mile packed into 0.2 square miles, there’s almost no natural space for runoff to go. Rooftops, driveways, sidewalks, and streets cover nearly everything so when it rains hard, water moves fast and has nowhere to absorb. That’s not a yard maintenance issue. That’s a hydrology problem that needs a real drainage system.
Once the right system is in place, the yard functions the way it should. Kids can use it again without tracking mud inside. The foundation stops taking on water. The soggy patch that’s been killing the grass for two springs in a row finally dries out. And you stop watching the weather forecast with dread every time a storm rolls through Delaware County.
We’ve been doing outdoor construction work across Delaware County for over 15 years. That includes the older, denser boroughs along the Philadelphia border places like East Lansdowne, where the housing stock is 80 to 100 years old, the lots are tight, and drainage problems have often been deferred through multiple ownership changes before someone finally decides to fix them right.
This isn’t a regional franchise with a call center routing your job to whoever’s available. When you work with us at Spennato Landscaping, you’re working with a team that has handled drainage, grading, retaining walls, and hardscape as one integrated operation not separate contractors who’ve never spoken to each other. We’ve built a reputation across Delaware County on exactly that kind of accountability.
East Lansdowne is already part of our service area. We know the property types here the Craftsman Bungalows, the American Foursquares, the twins with shared property lines and what it takes to install drainage that actually works in that environment without blowing up a small backyard to do it.
It starts with a site assessment. Before anything is recommended or priced, we walk the property to understand where water is coming from, where it’s going, and why it’s not moving the way it should. In East Lansdowne, that usually means looking at original grading that’s shifted over decades, downspouts discharging too close to the foundation, or low spots in the yard where water collects because there’s nowhere for it to drain. That diagnosis shapes everything that comes after.
From there, we design the right solution for the actual conditions on your property. That might be a French drain running along a fence line to intercept water before it reaches the foundation. It might be a catch basin at a low point, tied into a discharge line that routes water safely to the street or a dry well. In some cases, the grade itself needs to be corrected before any drainage system will perform properly and because we handle both grading and drainage, that’s done as one project, not two separate contractor relationships.
East Lansdowne Borough operates under Pennsylvania’s Act 167 Stormwater Management Ordinance, and the borough actively inspects stormwater improvements under its municipal code. Any drainage work that affects water flow needs to be done with that regulatory framework in mind. We handle that side of the process so you’re not left figuring out permit requirements on your own.

Drainage work in East Lansdowne requires a different approach than what you’d design for a newer suburban home on a half-acre lot in Broomall or Newtown. The yards here are small. The homes are old. The soil has been compacted, shifted, and built over for a century. And the freeze-thaw cycles that Delaware County gets every winter are hard on drainage infrastructure inferior pipe, inadequate gravel wrap, and poorly sloped systems can fail by March if they weren’t installed with Pennsylvania’s climate in mind.
Every drainage project we install is built to handle those conditions. That means properly graded pipe with the right fall to keep water moving, clean stone wrap around French drain lines to prevent silt clogging, and discharge points engineered to comply with East Lansdowne’s stormwater rules which require that only clean stormwater enters the borough’s municipal storm system. These aren’t optional details. They’re what separates a system that works for years from one that backs up the first time it rains hard.
The scope of each project is determined by what the property actually needs. Some East Lansdowne yards need a straightforward French drain installation along a problem area. Others need a combination of surface grading correction, subsurface drainage, and proper downspout management. The assessment tells you which. You won’t be sold a system your yard doesn’t need and you’ll know exactly what you’re getting and why before any work starts.
It depends on the scope of the project and where the water will discharge. East Lansdowne Borough operates under Pennsylvania’s Act 167 Stormwater Management Ordinance and maintains an active stormwater BMP inspection program under its municipal code. If your drainage project involves redirecting water flow near a watercourse or discharging to the municipal storm system, permits and DEP Regional Office approval may be required before work begins.
The borough also has a clear rule about what can enter the municipal storm inlets: stormwater only. That affects how discharge points are designed and where they terminate. A contractor who isn’t familiar with East Lansdowne’s specific code requirements can inadvertently create a permit violation that lands on you as the homeowner. We handle the permit and compliance side of drainage projects as part of the process so you’re not left researching borough ordinances on your own after the fact.
The honest range is wide anywhere from around $1,500 for a simple, short drain line to $15,000 or more for a complex system involving multiple catch basins, significant grading correction, and longer discharge runs. Most residential projects in Delaware County land somewhere in the $5,000 to $9,000 range depending on the scope.
What drives cost is mostly labor it typically accounts for 80 to 85 percent of the total. Linear footage of drain pipe, depth of excavation, soil conditions, and where the water needs to discharge all affect the final number. In East Lansdowne specifically, working in tight yards with limited access can add complexity compared to larger-lot properties. The most useful thing you can do before worrying about price is get a proper site assessment. Once the actual conditions are understood, the estimate reflects what your yard genuinely needs not a guess based on square footage alone.
In East Lansdowne, the most common causes come down to three things: original grading that no longer functions the way it was built, soil that’s been compacted or altered over decades of settling and root growth, and a lack of drainage infrastructure that was never installed in the first place. Most of the homes here were built in the 1920s and 1930s before modern stormwater engineering existed. The grading that was done back then wasn’t designed to account for how the surrounding neighborhood would develop, how the soil would shift, or how much impervious surface would eventually surround the property.
The borough’s density compounds it. With almost no open land to absorb runoff, water from rooftops, driveways, and streets has to go somewhere. If your yard sits at a low point relative to neighboring properties which is common in East Lansdowne’s tight residential blocks you may be collecting runoff from multiple surrounding lots, not just your own roof. A site assessment identifies exactly which of these factors is driving your specific problem, because the fix for a grading issue is different from the fix for a soil permeability issue or a neighbor’s runoff problem.
Exterior yard drainage can absolutely reduce or eliminate basement water intrusion but whether it fully solves the problem depends on where the water is coming from. If your basement is getting wet because water is pooling against the foundation wall outside, a properly installed French drain or grading correction that moves water away from the house can stop it at the source. That’s the most effective and least invasive solution when the cause is exterior surface water.
If the water is coming through the foundation itself due to hydrostatic pressure from a high water table, or through cracks that have developed in an aging foundation, exterior drainage helps but may need to be paired with interior waterproofing work. In East Lansdowne’s pre-war homes many of which have original stone or block foundations it’s worth having the source of the moisture identified before committing to any single solution. A good drainage contractor will tell you honestly whether yard drainage alone will solve your problem or whether you need to involve a waterproofing specialist as well.
Most residential French drain installations in Delaware County take one to three days from start to finish, depending on the length of the drain run, the depth required, and how complex the discharge routing is. A straightforward installation along a fence line or foundation edge on a typical East Lansdowne lot can often be completed in a single day. Projects that involve multiple drain lines, catch basins, significant grading work, or longer discharge runs to the street or a dry well will take longer.
Weather and ground conditions also factor in. Spring and fall are the most common times East Lansdowne homeowners schedule drainage work spring because the standing water problem just made itself obvious, and fall because they want it resolved before the ground freezes. Scheduling in advance during those peak windows is worth doing, because demand for drainage contractors in Delaware County picks up quickly after a wet spring. Once the work is done, the yard is restored and functional there’s no extended recovery period waiting for materials to settle before the system works.
Sometimes regrading alone is enough if the primary problem is that the yard slopes toward the house instead of away from it, correcting that slope can eliminate standing water without installing any additional drainage infrastructure. But in East Lansdowne, where soil has been compacted and altered over nearly a century, regrading alone often isn’t sufficient. Even with proper slope, water can still pool if the soil is too dense to absorb it or if the volume of runoff coming onto the property exceeds what the corrected grade can move.
The more accurate answer is that grading and drainage work best together. Regrading moves water in the right direction. A French drain or catch basin system gives it somewhere to go once it’s moving. Trying to do one without the other especially on a small, dense lot in a borough where neighboring properties are just feet away often produces a partial fix that leaves the homeowner frustrated. The site assessment is what determines which combination your specific yard needs. There’s no universal formula, and a contractor who recommends a solution before walking your property isn’t giving you a real answer.
