Local conditions
Why Bryn Mawr properties hold water
JHL Drainage Solutions diagnoses and corrects drainage problems throughout Bryn Mawr, Pennsylvania and the surrounding Montgomery County area. We are a licensed and insured Pennsylvania home improvement contractor (#PA035784), and every project starts with identifying the source of the water rather than assuming it.
Bryn Mawr is Main Line ground — older, larger properties in Lower Merion Township with mature specimen planting, stone walls, established hardscape and a great deal of roof area. Drainage corrections here are as much about access and restoration as about the system itself.
The housing predates modern stormwater management by a wide margin, and many properties carry legacy drainage of unknown routing: clay tile, early terracotta, or runs installed decades ago with no record of where they go. Locating what already exists is frequently the first useful piece of work, because tying into a legacy line that no longer discharges anywhere is a common way to make a problem worse.
The dominant condition in Bryn Mawr is concentrated roof and hardscape runoff on properties with limited unpaved ground left to absorb it. Moving that volume to a genuine outfall, without disturbing mature planting or historic hardscape, is the design constraint that shapes most of this work.

Questions
Bryn Mawr drainage questions
Why does my yard hold water in Bryn Mawr, PA?
Standing water in Bryn Mawr usually comes from one of four conditions: ground that falls toward the house rather than away from it, roof water released at the foundation, a low area with no outfall, or subsurface water moving laterally along the clay layer and surfacing partway down a slope. They look similar and need different corrections, which is why we assess before proposing a system.
Do I need a French drain or regrading in Bryn Mawr?
Regrading corrects water running across the surface toward the structure; a French drain intercepts water already moving through the ground. On Montgomery County properties the surface problem is the more common of the two and generally the cheaper correction, so it is worth confirming which condition you actually have before committing to the more involved system.
Do you need a permit for drainage work in Bryn Mawr?
It depends on the scope and the municipality. Requirements in Montgomery County are set at township and borough level, and work that affects a stormwater system, a floodplain or a regulated earth-disturbance threshold is treated differently from a short interception run. We confirm what applies to your Bryn Mawr address before work begins.
How much does drainage work cost in Bryn Mawr, PA?
Cost is driven by the length and depth of the run, ground conditions, what the outfall requires and how much restoration the site needs — a run to a natural daylight outfall is materially cheaper than one that needs a dry well or a pumped discharge. We provide a free written estimate after an on-site assessment rather than quoting by the foot in advance.
Which office serves Bryn Mawr?
Our Newtown Square office at 12 Smedley Ln, Suite #109, Newtown Square, PA 19073 serves Bryn Mawr. You can reach that office at (610) 800-0008. We are open Mon–Sat 8am–7pm.
Can drainage work be done in winter in Bryn Mawr?
Much of it can. Excavation is possible outside hard-frozen conditions, and winter is often when drainage problems are most visible. What winter does affect is lawn restoration — seed will not establish in cold ground, so where a run crosses turf we will usually stage the restoration for spring and say so in the estimate.
