Expert Yard Drainage Contractors Serving Mountlake Terrace
Standing water, soggy lawns, and drainage problems are common challenges for Mountlake Terrace homeowners — and they almost always have a solution. At New Life Rockeries, we've been solving yard drainage problems across Mountlake Terrace and surrounding communities since 1975, and we understand the soil conditions, rainfall patterns, and topography that make proper drainage critical in Western Washington.
Our Mountlake Terrace 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 Mountlake Terrace project.
Poor drainage is the #1 cause of retaining wall failure in Western Washington. Our crews are licensed, bonded, and insured in Washington State.
Mountlake Terrace's geology is characterized by Vashon Stade glacial deposits, with prevalent Alderwood-Kitsap and Alderwood gravelly sandy loam soils. These soil types, combined with the city's varied topography featuring significant elevation changes and steep slopes, often lead to poor drainage and increased risk of erosion. Retaining walls are frequently necessary to manage these challenging conditions, prevent landslides, and create stable, usable land.
The City of Mountlake Terrace requires a building permit for any new retaining wall or the rebuilding of an existing wall exceeding 4 feet in height. Additionally, projects involving retaining walls on slopes 15% or greater necessitate a geotechnical report.
A homeowner in the residential area near Veterans Memorial Park in Mountlake Terrace recently faced significant erosion in their sloped backyard. We designed and installed a multi-tiered retaining wall system, not only stabilizing the hillside but also transforming the previously unusable space into a functional terraced garden area, enhancing both safety and property value.

How Much Does Yard Drainage Cost in Mountlake Terrace?

What We Build
French Drain Installation
Perforated pipe systems installed in gravel-filled trenches that intercept and redirect groundwater away from your Mountlake Terrace 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 Mountlake Terrace 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 Mountlake Terrace home and landscaping. A natural, low-maintenance drainage solution integrated into your landscape.
Retaining Wall Drainage
Drainage systems installed behind Mountlake Terrace 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 Mountlake Terrace 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 Mountlake Terrace 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."
