Subsurface French drain systems that intercept groundwater and carry it away from the house before it reaches the foundation.
Overview
French Drains for Swarthmore properties
JHL Drainage Solutions installs french drain installation throughout Swarthmore, Pennsylvania and the surrounding Delaware County area. Subsurface French drain systems that intercept groundwater and carry it away from the house before it reaches the foundation.
Swarthmore borough sits above the Crum Creek valley, with ground falling away sharply on the creek side and much flatter conditions through the older residential streets. The two halves of that topography behave completely differently and are frequently confused when a system is designed from the street rather than from the ground.
Swarthmore splits between properties with real fall toward the Crum Creek valley and flatter interior streets with none. Which side a property sits on determines whether a gravity system is possible at all.
We are a licensed and insured Pennsylvania home improvement contractor (#PA035784). Every Swarthmore project begins with an on-site assessment and a free written estimate — we do not quote drainage work by the linear foot over the phone, because the variables that drive it are not visible from a description.

How this works on Swarthmore ground
Around Swarthmore borough, Swarthmore College, the Crum Creek valley, the practical questions for french drains are where the water originates, how much fall the property actually has, and where it can be released without creating a problem somewhere else — three things resolved on a site walk rather than on a plan.
A French drain works by giving subsurface water an easier path than the soil around it — perforated pipe bedded in washed stone, wrapped in filter fabric so fines cannot migrate in, laid on consistent fall to an outfall that is genuinely lower than the collection run.
Questions
French Drains in Swarthmore — common questions
How much does french drain installation cost in Swarthmore, PA?
Cost depends on the length and depth of the run, what the ground turns out to be, what the outfall requires and how much lawn or hardscape restoration is involved. We provide a free written estimate for Swarthmore properties after walking the site, rather than quoting a per-foot figure that changes once the conditions are visible.
Do I need a permit for french drains in Swarthmore?
It depends on scope. Requirements in Delaware County are set by the township or borough rather than county-wide, and work touching a stormwater system, floodplain or regulated earth-disturbance threshold is handled differently from a contained residential run. We confirm what applies to your Swarthmore address before starting.
How long does a French drain last?
A system built with filter fabric, washed stone and a maintained outfall can function for decades, because it has no moving parts. Systems that fail early almost always fail for one of three reasons: no fabric, unwashed aggregate, or an outfall that has become blocked or buried.
How deep does a French drain need to be?
It is set by where the water is moving, not by a standard depth. Shallow seepage is intercepted shallow; water relieving pressure at footing level sits deep. Depth drives cost more than proportionally, so it is worth establishing rather than assuming.
Can a French drain be installed under an existing lawn?
Yes, and most residential runs are. Trenching leaves a scar that needs topsoil and seed or sod to recover, and the restoration is a real part of the job — it is worth confirming it is included in any estimate you are comparing.
