Standing water in the yard, soggy lawns after every storm, water creeping toward the foundation. If your property in Hillsborough fights drainage problems every spring and fall, Lou Porchetta Paving has been solving those issues for Somerset County homeowners for more than 40 years.
Why Drainage Is a Bigger Deal in Hillsborough Than You Think
Hillsborough Township sits on a mix of clay-heavy and silty soils that drain slowly compared to the sandier ground further east. Combine that with the larger residential lots typical here in places like Belle Mead, Flagtown, and the Neshanic area, and you get a perfect setup for water to pool, migrate toward foundations, and undermine driveways and patios over time.
On top of soil, many Hillsborough homes rely on septic systems. Poor drainage isn’t just a cosmetic problem when there’s a leach field involved — saturated soil shortens the life of your septic and creates issues that are far more expensive to fix than installing a proper drainage system in the first place.
The fix isn’t guesswork. Every Hillsborough property we work on starts with on-site grade analysis so we know where water actually wants to go, and we design a system around that reality — not a one-size-fits-all template.
French drain installation by our crew — the most reliable subsurface fix for Hillsborough’s clay-heavy lots.
Drainage Services We Provide in Hillsborough
We install and repair the full range of residential and light commercial drainage systems for Hillsborough properties. Most projects involve more than one component working together — we’ll lay out exactly what your lot needs in a written estimate before you commit.
French Drains & Trench Drains
Subsurface gravel-and-pipe systems that intercept groundwater before it reaches the basement or compromises your driveway base. The most reliable solution for Hillsborough’s heavy clay sections.
Catch Basins & Yard Drains
Surface inlets that capture pooling water in low spots and route it to a safe discharge point. Especially useful on the wider lots you see in Belle Mead and the Amwell Road corridor.
Downspout Extensions & Connections
We tie roof runoff into buried solid pipe and discharge it well away from your foundation, eliminating the splash zones that erode mulch beds and crack walkways.
Grading & Slope Correction
Proper re-pitching of the soil around the home, driveway, or patio so water moves with gravity instead of against it. Often the single biggest fix on older Hillsborough properties.
Driveway & Apron Drainage
Trench drains across driveways, Belgium block gutter aprons, and curb-side capture to keep water off the asphalt and out of your garage.
Parking Lot & Light Commercial
For Hillsborough small businesses and HOAs: catch basin installation, asphalt re-pitching, and stormwater inlet repair to prevent ponding and pavement failure.

Our Process for Every Hillsborough Drainage Job
On-site evaluation. We walk the property after we understand the problem. We look at where water comes from, where it’s pooling, soil composition, existing slopes, and any nearby utilities or septic components.
Custom design. You get a written plan with the components we’re recommending, where they’ll go, what they’ll connect to, and a transparent price. No surprises.
Professional installation. Our own crew handles excavation, pipe and aggregate, restoration of the surface, and any related paving or stonework so you aren’t coordinating multiple contractors.
Final testing & cleanup. We flow-test the system, confirm everything pitches and drains correctly, and leave your property cleaner than we found it.
How much does drainage installation cost in Hillsborough?
Most residential drainage projects in Hillsborough fall between $1,800 and $9,500, depending on linear footage, depth, soil conditions, and how many components are tied together. A simple downspout extension is on the low end; a full perimeter French drain with catch basins and surface restoration sits at the upper end. We provide written estimates at no charge so you know exactly what you’re paying for.
Do I need a permit to install a French drain in Hillsborough Township?
For most residential French drains discharging to your own property, no permit is required. If the system ties into a municipal storm sewer, alters established grades significantly, or affects a regulated wetland or stream buffer, Hillsborough Township may require review. We pull any permits that are needed and handle the township coordination as part of the project.
What time of year is best to install drainage in Hillsborough?
Spring and fall are ideal because the ground is workable and we can verify performance against actual rain events. That said, we install drainage year-round in Hillsborough whenever the ground isn’t frozen solid. Many homeowners book us right after a wet spring once they’ve seen exactly where the water goes.
Will a French drain protect my septic system?
Indirectly, yes. A French drain or catch basin system that intercepts surface and ground water before it reaches a septic leach field reduces hydraulic load on the septic, which helps your system function as designed and extends its useful life. We’re careful to keep drainage runs and discharge points clear of any septic infrastructure on Hillsborough properties.
How long does a typical drainage project take?
Most Hillsborough projects are finished in one to three working days. A simple downspout tie-in can be a half-day job; a perimeter French drain with new grading and surface restoration is typically two to three days, depending on access and weather.
Can you fix drainage issues without tearing up my driveway or patio?
Often, yes. Catch basins, surface drains, and channel drains can be retrofitted through narrow trenches and stitched-in repairs. When a full-driveway re-pitch or trench drain across the apron is the right answer, we coordinate the asphalt or stonework in-house so the finished surface looks intentional, not patched.
