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 Retaining Wall Repair Cost in Mountlake Terrace?
Retaining wall repair costs in Mountlake Terrace depend on the wall type, extent of damage, length of wall, and whether drainage improvements are needed. Below are typical ranges based on our completed projects.

What We Build
Drainage Repair & Waterproofing
The #1 cause of retaining wall failure is drainage. We excavate behind the wall, install perforated drain pipe, add clean gravel backfill, and create proper drainage outlets to relieve hydrostatic pressure permanently.
Stone & Block Replacement
Loose, fallen, or crumbling stones and blocks are removed and replaced with matching material. We re-set displaced stones with proper batter (backward lean) and repoint mortar joints where needed.
Wall Straightening & Realignment
Leaning or bowing walls are carefully disassembled, the drainage and foundation issues corrected, and the wall rebuilt plumb and true. We never just push a leaning wall back — the root cause must be addressed.
Foundation & Footing Repair
Walls that have shifted due to inadequate foundation depth are excavated, re-footed to proper depth below frost line, and rebuilt. This is the most durable long-term repair for chronically failing walls.
Timber & Wood Wall Replacement
Rotting timber retaining walls are removed and replaced with natural stone or concrete block — materials that last 50+ years instead of 15. We handle full removal, disposal, and new wall construction.
Partial Section Rebuild
When only a section of your wall has failed, we rebuild just that portion — matching the existing stone type, color, and coursing pattern as closely as possible for a seamless repair.
What Our Customers Say

"Our 20-year-old rockery wall was leaning badly after a wet winter. NLR came out, assessed the damage honestly, and recommended targeted repairs rather than full replacement — saving us thousands. The repaired wall looks great."
"I was worried our failing retaining wall would be a massive expense. NLR diagnosed a drainage problem, fixed it properly, and rebuilt the failed section. Professional, honest, and the price was exactly as quoted."
