French Drains & Drainage in Exton, PA
Drainage is the service Exton generates most, and the reason is visible from the Route 30 and Route 100 corridors.
What Exton properties need from this work
Decades of commercial development along those corridors has covered a great deal of ground that used to absorb rain. Water that once soaked in now runs off, and it arrives somewhere. For houses downhill of that development, the volume crossing the property is frequently more than the original lot grading was ever designed to handle.
That shows up in predictable ways. Water standing against a foundation after storms, a driveway edge undermining, a low point in the garden that never dries out, a garage that takes water across the apron. These are symptoms of volume rather than of anything being broken, which is why regrading alone often does not fix them.
The durable answer is usually interception and a real outlet: catching water before it reaches the structure and piping it somewhere genuinely lower. Much of Chester County sits on clay heavy soil that absorbs slowly and stops absorbing entirely once saturated, so dry wells that rely on the surrounding ground accepting water are frequently the wrong solution here.

French Drains in Exton: common questions
More water crosses my property than it used to. What changed?
Usually upstream development. Every acre of parking, roof or roadway that replaces open ground converts rain that used to soak in into runoff that has to go somewhere, and it follows the land downhill.
Your lot was graded for the conditions at the time it was built. If the conditions upslope changed afterwards, the original grading is simply undersized for what arrives now. That is a volume problem, and it needs interception and an outlet rather than more grading.
Will a dry well work on my property?
It depends entirely on the soil, and in much of this area the answer is no. A dry well works by releasing collected water into the surrounding ground, so it needs ground that will accept it.
Clay heavy soils absorb slowly and stop altogether once saturated, which is exactly when you need the drain to work. On those soils a piped outlet carrying water to a genuinely lower point is the more reliable approach.
Do I need permission to change drainage in West Whiteland Township?
Often, yes. Work that alters where stormwater goes, discharges toward a neighbouring property, or enters a right of way commonly requires review, and townships here vary more than people expect.
Discharging onto a neighbour is the one worth being careful about. Solving your water by sending it next door creates a different and more expensive problem. Establish the permit position before work begins and get it in the contract.
