Fix the Source of Foundation Moisture

Improper downspout drainage is a leading cause of foundation moisture in Exton homes — roof water discharged at splash blocks saturates the first 2–3 feet of foundation soil. JHL Drainage Solutions installs underground downspout tie-ins that carry roof water 10+ feet from the foundation, preventing the saturation cycle that drives basement moisture in Chester County's clay soils.

Downspout Drainage FAQ — Exton

How much does underground downspout drainage cost in Exton?
Underground downspout tie-ins in Exton typically run $500–$1,500 per downspout. A full-home 4-downspout installation runs $2,500–$4,500. JHL provides free estimates from our West Chester office.
Will downspout drainage fix my Exton foundation moisture?
Often yes — concentrated downspout discharge at the foundation is one of the most common causes of basement moisture in Chester County homes. Underground tie-ins with pop-up emitters move roof water safely away.
How far should downspouts discharge from my Exton home?
A minimum of 10 feet from the foundation wall. Pop-up emitters close when dry to prevent animal entry. Chester County clay soils mean water discharged too close to the house stays saturated against the foundation longer than sandy soils.
