SoCal Exterior Services builds structural retaining walls and decorative masonry across the county. We handle everything from garden seat walls to tall engineered walls that need footings, rebar, drainage, and — above a certain height — a permit and engineer’s stamp. We build to hold, and we build to code.
Types of walls we build
- Structural CMU (concrete block) walls, stucco- or stone-faced
- Segmental retaining walls (SRW) for terraced hillside gardens
- Poured concrete walls where the load demands it
- Natural stone and boulder walls for a rugged, organic look
- Seat walls, planters, pilasters, BBQ islands, and outdoor fireplaces
Drainage is what keeps a wall standing
The most common reason a retaining wall fails is not weight — it is water. Soil behind a wall holds rain, and that saturated soil pushes with enormous hydrostatic force. Every wall we build includes the drainage the soil requires: gravel backfill, filter fabric, and perforated drain pipe that carries water away from the structure, plus weep holes where they belong. This is the invisible work that separates a wall that lasts from one that bulges and cracks after the first wet winter.
Permits and engineering
In most San Diego jurisdictions, retaining walls over four feet (measured from the bottom of the footing), or walls carrying a surcharge like a driveway or structure above, require a permit and engineered plans. We know these thresholds, coordinate the engineering when it is needed, and build to the approved detail so your wall passes inspection and protects your property for the long term.
What’s Included in Our Retaining Walls & Masonry Service
Every retaining walls & masonry project we take on is a complete scope, not a partial fix. Here’s what a typical job includes:
- Slope and load assessment to determine height, footing, and reinforcement needs
- Engineered plans and permit coordination when height or surcharge triggers them
- A proper footing plus gravel backfill, filter fabric, weep holes, and drain pipe
- Structural CMU, segmental block, poured concrete, or natural-stone construction
- Stone-veneer or stucco facing and a clean cap for a finished look
- Backfill, grading, and integration into your landscape or hardscape
Our Process
- 1Slope & load assessmentWe evaluate soil, height, and what the wall must hold, then determine whether engineering is required.
- 2Engineering & permitsFor taller or surcharged walls we coordinate stamped plans and pull the permit before building.
- 3Footing & drainageWe pour a proper footing and install gravel, fabric, and drain pipe so water never loads the wall.
- 4Wall constructionBlock is laid with steel and grout to the engineered detail, or stone is set for organic walls.
- 5Finish & backfillWe face, cap, and backfill the wall, then tie it into your grading and landscape.
What Affects the Cost
We don’t publish flat prices, because an honest number depends on your specific property. Here’s what shapes the estimate — and what we’ll walk through with you on site, free of charge:
- Wall height and length, and whether engineering/permits are triggered
- Wall type: segmental block vs. CMU vs. poured vs. natural stone
- Drainage complexity and the amount of backfill and export
- Facing and cap material — stucco, stone veneer, or split-face block
- Access for equipment and how far material must be moved by hand
Why San Diego Chooses SoCal Exterior Services for Retaining Walls & Masonry
Drainage built in, always
The leading cause of wall failure here is water, not weight. Every wall we build gets the gravel, fabric, weep holes, and drain pipe that keep saturated soil from loading the structure.
We know the code thresholds
We identify when a wall crosses the four-foot or surcharge line that triggers a permit and engineered plans, and we coordinate the stamped detail so your wall passes inspection.
Structural work that still looks designed
We face structural walls in stone or smooth stucco and cap them cleanly, so a wall doing serious retaining looks like part of the yard.
Licensed, insured, local

Wall Types, Finishes, and the Decorative Masonry We Build
Not every wall is the same structure, and matching the type to the job is part of the engineering. Segmental block — mortarless interlocking units — suits terraced garden walls and moderate heights and flexes nicely with our soils. Reinforced CMU, concrete block laced with steel and grout, is the workhorse for taller residential walls and anywhere you want a clean faced finish. Poured concrete steps in where loads are heaviest or geometry is complex, and natural stone or boulder walls fit rugged, organic slopes where the look matters as much as the function. The soils report, height, and any surcharge drive the choice — not preference alone, a theme we expand in engineering canyon retaining walls to code.
A structural wall does not have to look industrial. We face CMU in stone veneer or smooth stucco and cap it cleanly, so a wall doing serious retaining reads as a designed part of the yard. That finishing work is where retaining crosses over into the decorative masonry we self-perform.
Beyond retaining, our masonry crews build the features that make an outdoor space usable and finished: seat walls that double as casual seating, planters, pilasters and entry columns, BBQ islands and outdoor kitchens, and fire pits and fireplaces. Because it is the same team, these tie into your hardscape and paver work instead of looking bolted on.
- Segmental block — terraced garden walls and moderate heights
- Reinforced CMU — taller walls with a faced, finished look
- Poured concrete — heaviest loads and complex geometry
- Natural stone / boulder — rugged, organic slopes
- Decorative masonry — seat walls, planters, pilasters, BBQ islands, fireplaces
