Our Exterior Drainage Services in Wilmington, DE
Exterior water management is what sets us apart. The water your roof and gutters shed has to be carried away from the house, and that is exactly what these systems do. Not sure which drainage system you need? Start with the problem you see: soggy lawn, water at the foundation, puddles in a driveway, or downspouts dumping too close to the house. We’ll inspect the property and recommend the simplest system that solves the cause.
Exterior French Drains
Exterior French Drain Installation pulls groundwater away from your yard and foundation using perforated pipe set in gravel. It is the largest-ticket drainage fix and the most effective long-term solution for chronic saturation. We install every French drain in-house.
Yard Drainage Solutions
Yard Drainage Solutions in Wilmington, DE tackle soggy lawns, standing water, and poor grading that leave parts of your yard wet for days. We design exterior drainage tailored to how water actually moves across your property, restoring a usable, dry lawn.
Downspout & Buried Drains
Downspout & Buried Drain Installation buries and pipes roof runoff safely away from the foundation. Connecting your gutters to underground lines stops water from dumping at the base of your home, where it causes erosion and pooling.
Catch Basin Installation
Catch Basin Installation helps Wilmington homes with driveway puddles, patio low spots, and water collecting near walkways after heavy rain. We place the basin at the source of the pooling, connect it to a safe discharge route, and grade the surrounding area so water stops returning to the same spot.
Sump Pump Discharge Line (Exterior Only)
Sump Pump Discharge Line Installation pipes your pump's discharge away from the foundation (exterior lines only). A correct discharge line stops water from re-pooling at the house and resists freezing during Delaware winters.
Foundation Waterproofing (Exterior Only)
Exterior Foundation Waterproofing manages the outside causes of foundation water problems: grading, downspout discharge, surface drainage, and groundwater control. Our goal is to keep water from collecting against the foundation before it becomes an interior issue.
Every system above is built to keep water away from foundation areas with proven exterior drainage and water management. Whether you need French drain installation or full yard drainage solutions, we route the right fix to your property.

Drainage That Completes Roof-to-Ground Water Management
The water your roof and gutters shed has to go somewhere. A new roof or quality gutters move water off your house efficiently, but if it lands at the foundation, you have simply relocated the problem. Drainage carries that water the rest of the way, from roof to ground, and safely away from your home. That complete approach is the difference between managing rain and merely catching it.
We are exterior water management specialists. While roofers stop at the gutter and most gutter companies stop at the downspout, we engineer where the water finally goes. Our in-house crews handle big French-drain jobs from start to finish, so quality stays in our hands.
Rain Drainz is family-owned and operated, which means local accountability and a name you can hold responsible. We stand behind our installations with a workmanship warranty, so the system protecting your home is backed long after the crew leaves.
You can also pair drainage with our Gutters & Gutter Guards and Roofing services to complete the roof-to-ground bridge.
Exterior Drainage FAQs
Why is my yard always wet or flooding?
A wet yard usually comes from poor grading, downspouts that dump water at the foundation, or the absence of any drainage system. Water settles in low spots and clay soil holds it. Our Yard Drainage Solutions in Wilmington, DE and Exterior French Drain Installation correct the cause, not the symptom.
How do I keep water away from my foundation?
Keep water away from your foundation with three exterior moves: regrade soil to slope away from the house, bury downspout lines to carry roof runoff off, and install a French drain to intercept groundwater. Learn more about Exterior Foundation Waterproofing and Downspout & Buried Drain Installation.
What is a French drain, and how much does it cost in Delaware?
A French drain is a perforated pipe in a gravel trench that collects and redirects groundwater away from your home. It is typically the largest-ticket drainage fix, priced per linear foot in Delaware based on length, depth, and outlet. For a tailored quote, see Exterior French Drain Installation.
Where should my downspouts and sump pump discharge drain to?
Both should drain through buried exterior lines that release well away from the foundation, never beside it. This stops water from re-pooling against your home and freezing in winter. We install Downspout & Buried Drain Installation and exterior Sump Pump Discharge Line Installation.
Do you do interior basement waterproofing?
No. Rain Drainz handles exterior water management only: grading, drainage, downspouts, and discharge lines that keep water away from your home from the outside. We do not perform interior basement waterproofing, interior sump systems, or foundation-structural work. Our focus is stopping water before it reaches the house.
