Buildda Tip
Every retaining wall needs drainage behind it. Without a gravel backfill and drain pipe, water pressure builds up and eventually pushes the wall over. We install French drains behind every retaining wall we build.

Westchester attracts families seeking space and community on the westside. Small-town feel with tree-lined streets. Most properties are primarily 1940s-1960s with some newer construction.
Retaining Wall work in Westchester is permitted through LADBS, with typical timelines around 2-4 weeks for most outdoor projects. Online permit applications available. Permit applications are submitted before tear-off; inspections happen during the project per the authority's standard cadence.
Westchester's climate (near airport, sunny) shapes retaining wall decisions on local homes. Year-round outdoor living with abundant sunshine and moderate temperatures. Practical implication for this work: drought-tolerant landscaping recommended.
Most Westchester single-family homes are not in HOAs, so retaining wall decisions usually move directly from quote to scheduling without architectural review.
Local conditions in Westchester that affect this kind of work: large lots to maintain and airplane noise consideration. These typically need to be addressed in the project scope rather than discovered mid-job.

Our Process
We assess your slope, soil conditions, drainage patterns, and intended use. You'll receive recommendations on wall type, height, and materials best suited for your situation.
Walls over 3-4 feet typically require engineering. We create detailed plans showing wall dimensions, footing depth, drainage, and reinforcement requirements.
We submit engineered plans to your local building department and obtain necessary permits. Most retaining walls require permits and inspections.
The site is excavated to proper depth for footings. We compact the subgrade, install rebar or geogrid reinforcement, and pour the footing if required.
Your wall is built course by course with proper setback and drainage. Backfill is placed in lifts and compacted. Drainage systems are installed behind the wall.
Finish grading creates your new level area. Wall caps are installed, and the site is cleaned. We walk through the completed project and provide documentation.
