West Hills sits on the Harbor Hill Moraine Long Island’s highest terrain and that’s not just a geography fact. It means your soil is a patchwork of clay pockets and sandy zones that behave completely differently from each other. Water that falls on your upper slope doesn’t just sit there. It moves, it concentrates, and it ends up exactly where you don’t want it at the base of your foundation, pooling against your retaining wall, or turning the lower section of your yard into a swamp for days after a storm.
When that’s fixed correctly, the difference is immediate. Your lawn stops dying in the low spots. The musty smell near the basement disappears. You stop watching the weather forecast with dread every time a nor’easter rolls in off the Sound. That’s reclaiming your property.
The financial side matters too. Foundation repairs in this area run $23,000 to $48,000 when water damage goes unaddressed long enough. A properly installed drainage system costs a fraction of that and it addresses the cause, not just the symptom. For a West Hills homeowner who has invested significantly in their property, that math is straightforward.
We’re a landscape drainage and earthworks contractor serving the North Shore of Long Island, including West Hills and the surrounding Huntington Town communities. This isn’t a plumbing company that added drainage to its service list. Yard drainage how water moves across land, where it concentrates, and how to redirect it permanently is the work we do.
That distinction matters more in West Hills than almost anywhere else on Long Island. The hilly, wooded character of this hamlet, the proximity to West Hills County Park, and the moraine soil that runs beneath nearly every property here all require a contractor who actually understands terrain. We’ve worked on properties throughout this corridor from the wooded hillside lots near Sweet Hollow Road to the larger estates closer to the Dix Hills and Cold Spring Harbor borders and we bring that site-specific knowledge to every assessment.
Every project starts with a thorough walkthrough of your property. We map the water flow, evaluate the soil, and identify the source of the problem before we ever propose a solution. You get a written quote with a clear scope of work. No surprises.
It starts with a site assessment. We walk your property, trace the full path water is traveling from where it enters to where it’s accumulating and evaluate the soil conditions along the way. On moraine terrain like West Hills, that assessment is detailed. Clay-heavy subsoil behaves differently from the sandy zones right next to it, and a system designed without accounting for that will underperform the first time a real storm hits.
Once we understand what’s happening, we design a system for your specific property. That might mean a French drain intercepting water on the uphill side of your foundation, a catch basin at the low point of the yard, a channel drain at the base of a slope, or a combination of all three routed to a dry well or appropriate discharge point. Because most West Hills properties rely on cesspools or septic systems rather than municipal sewer, we site every discharge point carefully to protect your existing system that’s a detail that matters here and gets skipped by contractors who don’t know this area.
Before work begins, we confirm whether permits are required under Town of Huntington regulations. For most residential drainage projects, that process is straightforward, and we handle it. When excavation is complete, disturbed lawn and landscape areas are restored. You’re not left coordinating a separate landscaper to fix what we dug up that’s part of the job.

The drainage services we provide in West Hills are designed around what this terrain actually demands. French drain installation, catch basin systems, channel drains, dry wells, surface regrading, and full-property water management these aren’t add-ons. They’re the core of what we do, and each system is designed from scratch based on your property’s specific slope, soil profile, and water flow patterns.
West Hills properties present conditions you won’t find on the South Shore. The rolling topography near West Hills County Park, the mature tree cover that concentrates runoff and clogs drainage outlets with leaf litter, and the heterogeneous moraine soil that makes standard drainage templates unreliable all of it factors into how we design and install a system here. A French drain sized for average rainfall on a flat Commack lot is not the same as one designed to intercept slope-driven flow on a wooded West Hills hillside during a nor’easter. We size and design for the worst conditions your property will face, not the average ones.
Every installation comes with a written workmanship warranty. We’re fully licensed and insured in New York State, and we carry that documentation to every job. If you’ve had drainage work done before that didn’t hold up, that’s a conversation we’re ready to have because understanding why a previous system failed is often the most important part of designing one that won’t.
West Hills sits on the Harbor Hill Moraine, which is made up of poorly sorted glacial till a mix of clay, silt, sand, and rock that was deposited together without the natural sorting you’d find in sandy outwash areas. The result is soil with wildly inconsistent permeability. One section of your yard might drain reasonably well while the section right next to it holds water for three days because there’s a clay lens beneath the surface that water simply can’t push through.
On top of that, the topographic relief in West Hills is real. Water falling on an upper slope doesn’t stay there it moves downhill and accumulates at low points, foundation walls, and fence lines. Even a moderate rainstorm can deliver more water to those concentration points than the soil can absorb. That’s not a plumbing problem. It’s a terrain and soil problem, and it requires a drainage system designed around how water actually moves across your specific property.
A plumber fixes what’s happening inside pipes clogs, sewer backups, slow drains, cesspool issues. That’s legitimate work, but it has nothing to do with why your yard is flooding or why water is moving toward your foundation after a storm. If you search for drainage help in West Hills, most of what comes up is plumbing companies. They’ll clear a drain line, but they won’t fix the grade problem, the clay soil, or the slope that’s sending water directly at your house.
A landscape drainage contractor diagnoses and solves how water moves across and through your land. That means evaluating your yard’s slope, your soil profile, your existing drainage infrastructure, and where water is coming from then designing a system that redirects it appropriately. French drains, catch basins, dry wells, regrading these are land-based solutions for land-based problems. If your yard is flooding, you need someone who understands terrain, not pipe.
For most residential drainage projects, you’re looking at a range of roughly $2,000 to $8,000 depending on the scope the size of the property, how many components the system requires, and how complex the water flow pattern is. On a large, hilly West Hills lot with multiple problem areas, a comprehensive system can run higher, particularly if significant regrading is involved or if the discharge point requires a dry well installation.
What’s worth keeping in perspective is what you’re protecting. Foundation repairs from chronic water intrusion in this area run $23,000 to $48,000. A single basement flooding event averages $10,000 to $26,000 in damage costs. The drainage system is the intervention that prevents those bills not a luxury upgrade. Every project with us starts with a written quote that itemizes the full scope, so you know exactly what you’re getting and what it costs before any work begins.
It depends on the scope of the work. For most standard residential drainage installations a French drain, catch basin, or dry well on a single-family property permits through the Town of Huntington are either not required or are straightforward to obtain. However, if the project involves significant grading, changes to stormwater runoff patterns, or connection to public drainage infrastructure, a permit review is typically required under the Town’s stormwater management ordinance.
There’s also a Suffolk County layer to consider. Because most West Hills properties use cesspools or septic systems rather than municipal sewer, any drainage work near those systems needs to be sited carefully to comply with Suffolk County Department of Health Services guidelines. We handle the permit review process as part of the project we know what Huntington requires and we make sure the work is done in compliance, so you’re not left dealing with that on your own after the fact.
It can if it’s designed for them. That’s the critical distinction. A lot of drainage systems are sized for average rainfall conditions, which means they perform adequately most of the year and fail exactly when you need them most. In West Hills, the stress events are real: nor’easters in late fall and winter that drop several inches of rain in a short window, spring thaw periods when the ground is already saturated and can’t absorb anything, and summer thunderstorms that deliver two to four inches in under an hour.
A properly designed system accounts for peak event flow, not just average conditions. That means correctly sizing the pipe diameter, the catch basin capacity, and the discharge outlet for the volume of water your property will receive during a worst-case storm. It also means using appropriate geotextile fabric in French drain installations so the system doesn’t silt up within 18 months. We design every system with those peak conditions in mind because a drainage system that fails during a nor’easter isn’t doing its job.
Yes, and it’s a detail that matters a lot. Properties that border or sit adjacent to West Hills County Park face a specific drainage dynamic: natural water flow from wooded hillsides moves onto residential lots during and after rain events. That’s not water generated on your property it’s water traveling downslope from the park’s terrain onto yours, and it can be substantial during a heavy storm.
Beyond the volume issue, wooded properties accumulate leaf litter and organic debris that clog drainage outlets, catch basins, and French drain fabric over time. A system installed on a wooded lot needs to account for that with outlet placement that minimizes debris accumulation, geotextile fabric rated for organic load, and a maintenance plan that keeps the system clear. When we assess a park-adjacent property in West Hills, we factor in that upslope water contribution as part of the drainage load the system needs to handle. Ignoring it is one of the most common reasons drainage systems on wooded lots underperform.
