Standing water on a large Edgmont lot is not just an eyesore. When water pools near your foundation, it builds up pressure over time the kind that leads to basement leaks, mold, and structural damage that costs far more to fix than the drainage problem itself ever would have. A properly installed drainage system stops that cycle before it starts.
Edgmont’s rolling terrain and large residential lots many running an acre or more in neighborhoods like Springton Chase, Okehocking Hills, and Runnymeade Farms create drainage challenges that are more complex than what you’d find on a quarter-acre suburban lot. Water doesn’t just pool in one spot. It moves across the property, follows low points, collects near structures, and erodes naturalized areas before most homeowners even realize the full scope of what’s happening.
Once the drainage is right, you get your yard back. You stop watching where you step after a storm. You stop worrying about what’s happening to your foundation every time it rains hard. And because Edgmont sits within the Ridley Creek watershed where the township has formally adopted conservation plans for the Chester, Ridley, and Crum Creek systems a properly designed system also ensures your discharge is handled responsibly, not just redirected onto a neighbor’s property or into a protected waterway.
We’re based in Aston, PA, and have been doing grading and drainage work across Delaware County for over 15 years. That’s not a marketing number it’s the difference between a crew that knows how water moves through this county’s terrain and one that’s figuring it out on your property.
Edgmont is a specific kind of job. The lots are larger, the topography is more varied, and the township has real stormwater permit requirements that a contractor unfamiliar with the area simply won’t know about. We handle grading and drainage together, in-house, with no subcontractors. The same crew that assesses your property is the one doing the work and we’re accountable to you from start to finish.
Reviews mention Renato by name for a reason. When someone’s name is attached to the work, the standard is different. That’s the version of accountability that matters on a large Edgmont property where getting it wrong the first time is not a small inconvenience.
It starts with a site assessment not a sales pitch. Before anything gets recommended, our crew walks your property and maps how water is actually moving across it. On large Edgmont lots with varied elevation, this step matters more than most homeowners expect. A single visible low spot is rarely the whole story. The assessment identifies where water is entering, where it’s collecting, and what’s driving it there whether that’s a grading issue, a failed drainage system, or both.
From there, we design a solution around your specific property. That might be a French drain installation, a catch basin system, regrading a slope, or a combination of all three. If your project creates 500 or more square feet of new impervious coverage or disturbs more than 5,000 square feet of ground which is common on larger Edgmont lots Edgmont Township requires a Grading and Stormwater Management Permit under their 2023 stormwater ordinance. We’re familiar with that process and can walk you through what applies to your project before work begins.
Installation is done by the same in-house team that did the assessment. Once the system is in, we restore the site grading is cleaned up, disturbed lawn areas are addressed, and the property is left the way a crew that respects what you’ve built into it should leave it. Pennsylvania’s freeze-thaw cycles are factored into every installation: proper depth, correct slope, and full discharge so nothing is sitting in the pipe when temperatures drop.

Drainage work in Edgmont covers a range of solutions depending on what the property actually needs. French drain installation is the most common a perforated pipe set in a gravel trench that intercepts groundwater and redirects it away from structures or low areas. On larger lots, this often means longer runs, multiple collection points, and careful attention to where the water discharges. Given Edgmont’s proximity to Ridley Creek and the township’s adopted watershed conservation plans, discharge location is not an afterthought it’s part of the design.
Catch basin systems are often paired with French drains to handle surface water that collects faster than it can infiltrate. Regrading is frequently part of the solution as well, particularly in Edgmont’s older neighborhoods and in subdivisions like Springton Woods and Castle Rock, where original grading from the development phase has settled or been altered over the years. We handle all of this with one crew grading and drainage are not separated into two different contractors with two different timelines.
Every installation we complete is built to survive Delaware County winters. That means materials rated for Pennsylvania’s climate, proper burial depth to get below the freeze line, and a system slope that ensures complete drainage before the ground freezes. A drainage system that holds water through the winter is a drainage system that fails in the spring and that’s not the outcome you’re paying for.
Yes, in many cases it does. Edgmont Township requires a Grading and Stormwater Management Permit for any project that creates 500 or more square feet of new impervious coverage, or that involves grading disturbing more than 5,000 square feet of ground. On a typical Edgmont residential lot which often runs an acre or more it’s not unusual for a drainage project to hit those thresholds, especially when regrading is part of the scope.
The township adopted a comprehensive Stormwater Management Ordinance in 2023 (Ordinance No. 251), and it requires compliance with the Delaware County watershed plans for the Chester, Ridley, and Crum Creek systems. Yerkes Associates serves as the township’s engineering inspector for stormwater and grading work. If you’re not sure whether your project requires a permit, that’s one of the first things to clarify before any work starts and it’s something we can help you work through based on what your property actually needs.
French drain installation typically runs between $5,000 and $9,250 for a standard residential project, though complex systems on large properties can reach $15,000 or more. On Edgmont’s larger lots where drainage problems often span more of the property and require longer pipe runs, multiple catch basins, or coordinated regrading it’s reasonable to budget toward the higher end of that range.
Labor makes up the majority of the cost, usually 80 to 85 percent of the total. The rest is materials pipe, gravel, catch basins, and any fabric or connectors the system requires. The more useful way to think about the cost is relative to what you’re protecting. Homes in Edgmont’s established neighborhoods frequently carry values well above $700,000. Foundation repair alone can run $15,000 to $30,000 or more. A drainage system that prevents that outcome is not an expense it’s straightforward math.
Standing water after rain is almost always caused by one of three things: poor grading that directs water toward a low point instead of away from it, soil that can’t absorb water fast enough, or a drainage system that’s undersized, clogged, or was never installed in the first place. In many cases, it’s a combination of more than one.
In Edgmont specifically, a significant number of residential neighborhoods Runnymeade Farms, Springton Woods, Castle Rock, The Arbors at Edgmont were developed from former farmland. When those properties were subdivided, natural drainage patterns were replaced with engineered systems that are now aging. Grading that was done during the original development may have settled or shifted, and drainage infrastructure installed 20 or 30 years ago may simply not be functioning the way it was designed to. That history is worth knowing before assuming the problem is something you caused or something simple to fix.
We handle both grading and drainage with the same in-house crew. That matters more than it might seem at first. Grading and drainage are not independent problems the slope of the ground determines where water goes, and a drainage system installed without correcting the grading is fighting an uphill battle from day one. When two separate contractors handle those two components, you get two separate timelines, two different standards of workmanship, and no single point of accountability when something doesn’t work right.
On a large Edgmont property with rolling terrain, mature landscaping, and potentially multiple drainage problem areas, having one crew that understands the full picture is the difference between a system that works and one that addresses the most visible symptom while the underlying cause continues. The assessment, the grading, the drainage installation, and the site restoration are all handled by the same team.
The honest answer is that you don’t know until someone assesses the property properly. A French drain is the right solution for intercepting groundwater that’s migrating through the soil toward a structure or collecting in a persistent low area. But not every standing water problem requires one. Some properties need regrading to redirect surface flow. Some need extended downspouts and a properly directed discharge point. Some need a catch basin in one specific location with a short pipe run to daylight.
The mistake most homeowners make is hiring a contractor who shows up, sees standing water, and quotes a French drain without fully mapping how water moves across the entire property. On a large Edgmont lot, that shortcut almost always means the system underperforms because it only addresses part of the problem. A real site assessment takes more time upfront but it’s the only way to know what the right solution actually is before money gets spent.
Late summer through early fall is generally the best window for drainage installation in Edgmont roughly August through October. The ground is workable, the weather is more predictable than spring, and completing the project before the ground freezes gives the system time to settle and function through the first significant rain events before winter arrives. Spring is when drainage problems are most visible, but it’s also when the ground is saturated and the conditions for installation are least ideal.
That said, if you’re seeing active water intrusion near your foundation or significant erosion, waiting for a preferred season is not always the right call. Edgmont’s proximity to Ridley Creek and its tributaries means that properties in lower-lying areas of the township can experience real water pressure during heavy spring rain events the kind that accelerates foundation damage quickly. If the problem is urgent, the right time to address it is before the next major storm, not after the calendar turns.
