From French drains and dry wells to catch basins, grading and downspout drainage, Islip French Drains handles soggy yards, standing water and runoff across Islip and the surrounding Town of Islip communities.
The Problem
Water has nowhere to go — so it pools against your home.
Across Islip and the Town of Islip, drainage conditions vary from property to property. Long Island's subsurface includes mixtures of sand, gravel, and clay, and the local water table and lot grading can change how quickly stormwater leaves a yard. Homeowners often notice the same symptoms: puddles that linger, spongy lawns, runoff near the foundation, and basement seepage after heavy storms.
Recurring drainage problems can contribute to erosion, damaged landscaping, persistent dampness, and water pressure near the foundation. The right fix depends on the source of the water — which may call for a French drain, catch basin, dry well, downspout piping, grading, or a combination of systems.
Drainage Solutions
Solutions for every drainage problem
From subsurface French drains to downspout systems and re-grading, the right fix depends on your property's water source, soil, and slope.
French Drain Installation
Subsurface trenches lined with gravel and perforated pipe that capture groundwater and redirect it away from your foundation before it ever reaches your basement.
- Redirects groundwater from foundations
- Relieves hydrostatic pressure
- Discreet, landscape-friendly design

Yard Drainage
Surface and subsurface systems that eliminate standing water, soggy lawns, and pooling after heavy rain so your yard stays firm and usable.
- Resolves standing water & soggy turf
- Manages downspout runoff
- Protects landscaping and hardscaping

Dry Wells & Catch Basins
Underground storage and surface inlets that collect runoff and slowly release it into the surrounding soil, keeping water away from your foundation.
- Captures downspout & surface runoff
- Reduces erosion and pooling
- Low-maintenance, underground design

Yard Grading & Swales
Re-sloping and re-contouring your lawn so surface water flows away from your foundation instead of collecting in low spots against your home.
- Directs surface water away from home
- Prevents foundation seepage
- Restores a firm, usable lawn

Downspout Drainage & Extensions
Underground piping that carries roof runoff from your downspouts out to a safe discharge point, stopping erosion and pooling at the foundation.
- Moves roof runoff away from foundation
- Stops erosion at downspout outlets
- Pairs with dry wells and catch basins

Drainage questions, answered
What is a French drain?
A French drain is a subsurface trench filled with gravel and a perforated pipe that collects groundwater and redirects it away from your home's foundation, preventing water buildup and seepage.
How much does French drain installation cost in Islip?
Costs vary based on the length of the drain, soil conditions, and the extent of the drainage problem. The best way to get accurate pricing is to request a free estimate.
Which areas can I request an estimate in?
Estimate requests are available in Islip, NY and surrounding Town of Islip communities, including West Islip, East Islip, Bay Shore, Brentwood, Central Islip, Islip Terrace, Bohemia, Oakdale, and nearby areas. Estimate availability varies by project type and location.
Is the estimate really free?
Yes. Drainage estimates are free and come with no obligation.
How quickly will I hear back?
After you submit your request, we typically respond within one business day to discuss your drainage problem and schedule an estimate.
Can grading fix my drainage problem without a drain?
In some cases, yes. If water pools because of a low spot or a slope pitched toward the house, re-grading may redirect runoff without installing a drain. An on-site assessment can determine whether grading alone is enough or another drainage component is needed.
Why do my downspouts cause pooling near the house?
Downspouts concentrate roof runoff into a small area. If they discharge beside the foundation, the surrounding soil can become saturated quickly. Depending on the property, buried piping, a dry well, or another approved discharge strategy may help move that water away from the house.
Do I need a permit for a French drain in the Town of Islip?
Permit requirements depend on the scope of the work. The Town of Islip Engineering Division publishes requirements and applications for land grading, dewatering, road openings, and site work. A contractor should confirm which Town requirements apply to the specific property and drainage plan before work begins.
Who contacts New York 811 before drainage excavation?
For excavation work performed by a contractor, New York 811 states that the contractor or excavator is responsible for the 811 request. Excavators and contractors in Nassau and Suffolk Counties must contact 811 at least two working days before mechanized digging or excavation.
