Standing water isn’t just an eyesore. In Coram, where a lot of the housing stock dates back to the 1950s and 60s, water that sits near a foundation for days is quietly doing damage that shows up as a five-figure repair bill later. Foundation repairs from chronic water intrusion run $23,000 to $48,000. A properly installed drainage system costs a fraction of that and eliminates the risk before it becomes a problem.
Beyond the foundation, there’s the yard itself. Soggy turf, dead patches, and soil that stays saturated for days after a storm aren’t just cosmetic issues they’re signs that water has nowhere to go. Once that’s corrected, your lawn recovers, your landscaping holds, and you stop dreading the forecast every time a nor’easter rolls through.
Coram’s central Suffolk County soils have been compacted over decades of suburban development. What was once permeable, glacially deposited sandy soil now holds water in ways most homeowners don’t expect. A drainage system designed specifically for your yard’s grade, soil condition, and water flow path changes all of that not just for the next light rain, but for the storms that actually test it.
We’re a landscape drainage contractor serving Coram and the surrounding communities in Suffolk County. We focus specifically on how water moves across and through residential properties not general landscaping, not plumbing, not a little of everything. Drainage is what we do, and that focus matters when the job requires real site analysis, not a quick guess and a French drain.
Every project starts with a proper site assessment. We map where the water originates, how it travels across your property, and where it ends up. That’s the only way to design something that actually works. In Coram, where Town of Brookhaven code explicitly prohibits redirecting stormwater onto neighboring properties, getting that design right isn’t just good practice it’s legally required.
We work across the hamlet regularly, from the older ranch homes off Middle Country Road to the newer communities along Route 112. If you’ve had drainage work done before that didn’t hold up, we can tell you why and fix it the right way.
It starts with a site visit. Before anything is quoted or scheduled, we walk your property and trace the full water flow path where it enters, where it collects, and what’s blocking it from moving out. In Coram, that often means accounting for compacted soil, older grading that no longer performs, and impervious surfaces like driveways and patios that redirect runoff in ways the original yard wasn’t designed to handle.
From there, we design a system matched to your specific conditions. That might mean a French drain, a catch basin, a dry well, channel drains along a driveway edge, or a combination of several. The solution depends on what the site actually needs not what’s easiest to install. We also make sure every design complies with Town of Brookhaven stormwater requirements, including the rule that water cannot be redirected onto a neighboring property. That’s not a detail most homeowners know to ask about, but it’s one that protects you legally if a neighbor ever raises a concern.
Once the work is done, we restore what we disturbed. Turf, grading, and landscaping are brought back to finished condition. When we leave your property, it should look better than it did before we arrived because the drainage is now part of the landscape, not just dropped into it.

Drainage systems in Coram need to perform in conditions that push them hard nor’easters that deliver several inches of rain over 24 to 48 hours, summer thunderstorms that dump an inch or more in under an hour, and spring snowmelt that saturates already-wet ground for weeks. A system sized for a mild spring shower will fail when it matters most. Everything we install is designed for peak rainfall events, because that’s the only honest standard for Long Island.
The services we provide include French drain installation, catch basin and dry well systems, channel drains, surface regrading, and full stormwater management design for residential properties. For older homes in the historic core of Coram the ranch and Cape Cod styles built decades before current drainage standards we specialize in retrofitting systems into established yards without destroying existing landscaping or mature trees in the process.
Every project comes with a written, itemized quote before a single shovel moves. The number you approve is the number on your final invoice. We also provide a written workmanship warranty on all drainage installations if a system we install doesn’t perform as designed within the warranty period, we come back and make it right. That commitment matters in a community where home values are approaching $550,000 and the cost of getting drainage wrong keeps climbing.
This is one of the most common situations we run into. A previous drainage installation fails for a few predictable reasons: the system was undersized for the rainfall events that actually hit Long Island, the wrong solution was chosen for the soil conditions on that specific property, the outlet was placed too close to the house or at a point where water has nowhere to go, or no geotextile fabric was used and the system silted up within a season or two.
In Coram specifically, central Suffolk County’s compacted suburban soils behave differently than they appear. What looks like permeable ground often has a compaction layer just below the surface that blocks infiltration entirely. A French drain installed without accounting for that layer will back up and fail. When we assess a property where previous drainage work didn’t hold up, we look for exactly these failure points and we design the replacement system around what the site actually needs, not what’s quickest to install.
The right system depends entirely on your specific yard its grade, soil composition, the volume of water you’re dealing with, and where that water is coming from. For most residential properties in Coram, the most common solutions are French drains, catch basins, dry wells, channel drains along hardscaped edges, and surface regrading to correct slope issues that send water toward the house instead of away from it.
Many older homes in Coram particularly the ranch and Cape Cod styles built in the 1950s through 1970s have no meaningful drainage infrastructure at all. These properties were built before current stormwater standards, and the drainage challenges they face today reflect decades of soil compaction, added impervious surfaces, and infrastructure that was never designed for the rainfall intensity Long Island now regularly sees. For these homes, a retrofit approach is usually necessary, and it requires working carefully around existing landscaping, utilities, and structures. We do that assessment before recommending anything.
It depends on the scope of the work. Smaller drainage installations a catch basin, a French drain, minor regrading often fall below the threshold that requires a formal permit. However, larger drainage projects, any work near wetlands, and projects that involve significant grading or stormwater conveyance changes may require review under Town of Brookhaven Code Chapter 86, which governs stormwater management and erosion control across the town.
There’s also an important rule that applies to every drainage project in Coram regardless of size: Town of Brookhaven Code Section 86A-5.A prohibits redirecting stormwater runoff onto neighboring properties without prior approval from an authorized body. This isn’t a technicality it’s an enforceable code provision that can result in mandatory remediation and neighbor disputes if a system is designed without accounting for it. We design every drainage system in compliance with Brookhaven’s stormwater requirements, so you’re protected from that liability before the project even starts.
Drainage costs vary based on the size of the area, the complexity of the system, and what the site actually requires. For a straightforward French drain installation on a standard residential lot in Coram, you’re generally looking at a range of $2,500 to $6,000. More comprehensive systems catch basins, dry wells, channel drains, or full stormwater management design for a larger property typically run $5,000 to $10,000 or more depending on scope.
The more useful frame, though, is what the alternative costs. Foundation repairs from chronic water intrusion in this area run $23,000 to $48,000. Basement flooding incidents average $10,000 to $26,000 per event. With median home values in Coram approaching $550,000 and appreciating at 7 to 9 percent annually, the math on a properly installed drainage system is straightforward it’s one of the few property investments that pays for itself the first time it prevents a major damage event. Every written quote from us is itemized, so you know exactly what you’re getting for the number before any work begins.
Most residential drainage installations in Coram take one to three days depending on the system size and complexity. A single French drain or catch basin on a standard lot is typically a one-day job. A more involved system with multiple components regrading, dry well installation, channel drains may run two to three days.
What your yard looks like when we’re done matters to us, and it’s something we address directly before work starts. Drainage installation involves excavation, which means disturbed turf and exposed soil during the process. Once the system is in place, we restore the affected areas regrading, reseeding or resodding as needed, and returning the yard to finished condition. The drainage infrastructure itself is designed to integrate into the landscape rather than sit on top of it. When the project is complete, the visible result should be a yard that looks clean and intentional not a yard that looks like it had work done.
This is a question worth answering clearly because it’s the source of a lot of wasted time and money. Plumbers handle pipes sewer lines, water supply, drain connections inside or immediately adjacent to a structure. When water is backing up from a drain inside your home or a pipe is blocked underground near your foundation, that’s a plumbing call.
When water is pooling in your yard, running toward your foundation after a storm, saturating your lawn, or collecting in low spots that take days to drain that’s a land and grading problem, not a pipe problem. A plumber has no reason to assess your yard’s slope, your soil’s infiltration rate, or how water flows across your property during a nor’easter. That’s what we do as a landscape drainage contractor. In Coram, where many homes sit on lots that have been graded, compacted, and built around for 50 or more years, the drainage challenges are almost always about how water moves across the land and solving that requires someone who understands site hydrology, Town of Brookhaven stormwater code, and how to design a system that performs under real Long Island conditions.
