Expert Yard Drainage Contractors Serving Greater Seattle
Standing water, soggy lawns, and flooded basements are common problems for Pacific Northwest homeowners — and they almost always have a drainage solution. At New Life Rockeries, we've been solving yard drainage problems across the greater Seattle area for over 50 years, and we understand the soil conditions, rainfall patterns, and topography that make proper drainage critical in Western Washington.
Our drainage installations address the root cause of water problems — not just the symptoms. We assess your property's grading, soil type, and water flow patterns to design a drainage system that moves water away from your home, yard, and retaining walls effectively and permanently.
Whether you need a French drain to intercept groundwater, a catch basin to collect surface runoff, a swale to redirect water flow, or a complete drainage system for a new retaining wall, our team brings the same level of care and expertise to every project.
Poor drainage is the #1 cause of retaining wall failure in Western Washington. If you have a retaining wall, proper drainage isn't optional — it's essential. Our crews are licensed, bonded, and insured in Washington State.

What We Build

French Drain Installation
Perforated pipe systems installed in gravel-filled trenches that intercept and redirect groundwater away from your home, yard, and retaining walls. French drains are the most effective solution for chronic wet areas and soggy lawns in the Pacific Northwest.

Catch Basins & Surface Drains
Surface drainage structures that collect and redirect runoff from driveways, patios, low spots, and downspouts. We install catch basins, channel drains, and area drains connected to underground pipe systems that discharge water safely away from your property.

Swales & Grading
Graded drainage channels and yard regrading that redirect surface water flow away from your home and landscaping. Swales are a natural, low-maintenance drainage solution that can be integrated seamlessly into your landscape design.

Retaining Wall Drainage
Drainage systems installed behind retaining walls to prevent hydrostatic pressure buildup — the #1 cause of retaining wall failure. We install drain pipe, gravel backfill, filter fabric, and weep holes as part of every new wall installation and repair.

Downspout Drainage
Underground pipe systems that capture roof runoff from downspouts and carry it away from your foundation and yard. We connect downspouts to underground drain lines that discharge to the street, a dry well, or a suitable outlet.

Dry Wells & Infiltration Systems
Underground infiltration systems that collect and slowly release water into the soil. Dry wells are ideal for properties where water cannot be discharged to the street and the soil has adequate permeability.
What Our Customers Say
"We had chronic standing water in our backyard every winter. NLR installed a French drain system and the problem is completely solved. They diagnosed the issue accurately, explained the solution clearly, and the installation was clean and professional."
"Our retaining wall was failing because of poor drainage behind it. NLR repaired the wall and installed a proper drainage system at the same time. Two years later, no problems. Highly recommend their integrated approach."
"Water was pooling against our foundation every winter. NLR installed catch basins, connected our downspouts to an underground system, and regraded the yard. The difference is remarkable. Professional team, fair price."
