Expert Yard Drainage Contractors Serving Duvall
Standing water, soggy lawns, and drainage problems are common challenges for Duvall homeowners — and they almost always have a solution. At New Life Rockeries, we've been solving yard drainage problems across Duvall and surrounding communities since 1975, and we understand the soil conditions, rainfall patterns, and topography that make proper drainage critical in Western Washington.
Our Duvall 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 expertise to every Duvall project.
Poor drainage is the #1 cause of retaining wall failure in Western Washington. Our crews are licensed, bonded, and insured in Washington State.
Duvall's topography, characterized by forested hills and sloped terrain, often presents challenges for property owners. The underlying glacial till, while firm, necessitates careful consideration of drainage and foundation stability for any retaining wall or rockery project. Proper design is crucial to manage surface water runoff and prevent erosion on these naturally inclined landscapes.
The City of Duvall Building Division requires a permit for retaining walls and rockeries exceeding four feet in height, especially if supporting a surcharge or sloped ground. Homeowners should consult the Permitting Center for specific requirements and potential needs for engineered drawings.
A homeowner in The Ridge at Big Rock community in Duvall recently faced significant erosion on their sloped backyard. We designed and installed a multi-tiered retaining wall system, incorporating native rockeries, which not only stabilized the hillside but also created usable, terraced garden spaces, enhancing both safety and aesthetic appeal.

What We Build
French Drain Installation
Perforated pipe systems installed in gravel-filled trenches that intercept and redirect groundwater away from your Duvall 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 Duvall driveways, patios, low spots, and downspouts. Connected to underground pipe systems that discharge water safely away.
Swales & Grading
Graded drainage channels and yard regrading that redirect surface water flow away from your Duvall home and landscaping. A natural, low-maintenance drainage solution integrated into your landscape.
Retaining Wall Drainage
Drainage systems installed behind Duvall retaining walls to prevent hydrostatic pressure buildup — the #1 cause of retaining wall failure. Includes drain pipe, gravel backfill, filter fabric, and weep holes.
Downspout Drainage
Underground pipe systems that capture roof runoff from Duvall downspouts and carry it away from your foundation and yard. We connect downspouts to underground drain lines that discharge safely.
Dry Wells & Infiltration Systems
Underground infiltration systems that collect and slowly release water into the soil. Dry wells are ideal for Duvall 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."
