Hummelstown's historic borough is built along the Swatara Creek, and its older brownstone and stone-foundation homes were never designed for modern stormwater loads. Basements in the low-lying blocks near the creek take on water fast during spring thaw and summer downpours. An exterior french drain paired with a sump system is the standard fix for these older Hummelstown foundations.
Hummelstown's stone-foundation homes along the Swatara Creek were built for a stormwater world that no longer exists, and the low-lying blocks near the creek still take on water fast during spring thaw and summer downpours. An exterior french drain and sump handle the volume, but stone foundations this old often have their own problem: mortar joints and porous stone that let moisture through even when the yard itself is dry. Waterproofing in Hummelstown usually means pairing drainage for the water table with a wall treatment for what is coming through the stone itself, especially on the creek-adjacent blocks where both show up on the same house.
Not every wet basement is a drainage problem, and not every drainage problem is solved by one drain. Basement waterproofing in Hummelstown covers the whole set: interior and exterior drain tile, a sump pump with a battery backup, waterproof membranes and wall coatings, window well and floor drains, and repair of the cracks the water is coming through. Which combination your home needs depends on where the water is actually getting in, across the historic borough, the Swatara Creek blocks, and the residential streets off Main Street. That is what the free on-site look is for.

Most residential french drain projects in the Hershey, Harrisburg, and Lancaster area run between $3,000 and $12,000, depending on length, depth, whether it is interior or exterior, and how the water is being discharged. Simple yard drains sit at the low end; full basement perimeter systems with a sump pump sit higher. We give a firm price after a free on-site look, never a vague phone quote.
A correctly installed french drain, with proper filter fabric, clean stone, and the right slope, typically lasts 20 to 30 years or more. That is a general industry range, not a promise about any one job. The french drains that fail early were almost always installed without fabric, with the wrong stone, or at the wrong slope. Done right, it is a one-time fix.
It depends on your home and lot. Exterior drains intercept water before it reaches the foundation and are ideal when there is room to excavate. Interior drains are the practical choice for finished basements, tight urban lots, or homes where outside digging is not feasible. We walk your property and recommend the one that actually solves the problem, not the one that is easiest for us.
Yes. Requesting an estimate here is free and comes with no obligation. A real drainage estimate is done on-site, looking at your grade, your foundation, and where the water is actually coming from, not quoted blind over the phone.
Yes, always. Any contractor you hire for drainage work in Pennsylvania should carry liability insurance and be a registered PA home improvement contractor. Ask for the proof before any work begins. It is a fair question, and a good installer will have a straight answer.
