Downspout Drainage & Tie-Ins — Bryn Mawr

On older Bryn Mawr properties, downspout drainage is frequently the most overlooked contributor to basement moisture — roof water discharged within a few feet of the foundation saturates clay soil against the wall continuously during every rain event. JHL Drainage Solutions installs underground downspout tie-ins that carry roof water well away from Bryn Mawr foundations.

Downspout Drainage FAQ — Bryn Mawr

How much does underground downspout drainage cost in Bryn Mawr?
Underground downspout tie-ins in Bryn Mawr typically run $500-$1,500 per downspout. Larger homes with more downspouts run $3,000-$6,000 for full installations. JHL provides free estimates.
Can downspout drainage fix my Bryn Mawr basement moisture?
If downspout discharge at the foundation is contributing — which it frequently is in older Main Line homes — yes. Underground tie-ins are often the highest-impact single improvement for Bryn Mawr homes with chronic basement moisture.
How far should Bryn Mawr downspouts discharge from the foundation?
Minimum 10 feet, via pop-up emitter. Bryn Mawr's larger lots typically allow for longer runs — and we take advantage of that space to maximize discharge distance from the foundation.
