Daly City hills and clay soils push hard on poorly built walls. We build retaining walls with proper drainage and deep footings so your slope stays put through every rainy season.
Concrete retaining walls in Daly City hold back soil on sloped lots, prevent erosion onto driveways and foundations, and create level usable space where there was only hillside before. Most residential wall projects take two to five days from excavation to backfill, depending on length, height, and whether a permit is required.
Many Daly City homeowners reach out after noticing soil creeping downhill after rain or an older wall starting to lean. Concrete retaining walls are built for exactly those situations - they are the permanent fix rather than a patch. If you are also dealing with steps leading up to a terrace, our concrete steps construction work pairs naturally with a new wall.
We work on Daly City lots every week - we know the clay soils, the tight access, and what the city building division requires. There is no guesswork about whether your project needs a permit or how to drain the wall properly for a wet winter.
If you see dirt creeping downhill after a storm - bare patches above and a pile of soil below - your slope is actively eroding. In Daly City's hilly neighborhoods this often happens along the back or side of a property where the grade drops sharply. Left alone, erosion undercuts fences, damages foundations, and can affect neighboring lots.
An older wall that is starting to lean away from the slope, or showing horizontal cracks running across the face, is under more stress than it can handle. Horizontal cracks in particular signal that the wall may be close to failing. Getting this assessed before the next rainy season is worth doing now rather than after a collapse.
When a slope above your home lacks proper drainage or a retaining wall, rain funnels straight toward your foundation. If water collects against your house, garage, or fence line during a storm, a retaining wall with drainage behind it is often the right fix. Daly City winters make this a common problem on hillside lots.
Many Daly City backyards have slopes too steep to mow, plant, or use for anything practical. A retaining wall creates a level terrace behind it, turning unused hillside into actual outdoor space. On small Daly City lots where every square foot matters, that change is significant.
We build both poured concrete walls and concrete block walls, and we recommend the right type based on your slope, wall height, and available access. Poured concrete is a single continuous structure - very strong for taller walls or sites with heavy soil loads. Concrete block walls are built with stacked block filled with concrete and steel reinforcement, and they work well on tighter sites where large equipment cannot get close. Both options include proper drainage behind the wall as standard - not an add-on.
For homeowners who also want to add usable steps leading up from the new terrace, our concrete steps construction service integrates directly with a retaining wall project. And when the flat area behind the wall becomes a patio or outdoor room, our concrete floor installation team can finish the surface. We handle permit applications for walls requiring city approval, including coordination with a licensed engineer when the wall height or slope requires a stamped plan.
Best for taller walls, heavy soil loads, or sites where maximum strength is the priority.
Well-suited for sites with limited equipment access or when design flexibility matters.

Every wall we build includes gravel backfill and drainage pipe - essential for Daly City winters.
Daly City sits on the northern slope of the San Francisco Peninsula, and neighborhoods like Westlake and St. Francis Heights have significant grade changes between properties. Retaining walls are not a luxury here - they are often the only practical way to create usable flat space or stop a hillside from eroding onto a neighbor's yard. Add clay-heavy soils that swell in the wet season and shrink when dry, and you have conditions that are genuinely hard on walls that were not built for them. A wall that looks fine in October can start leaning by March if the drainage behind it was not done right.
We regularly work in Pacifica and San Francisco, where hillside terrain and wet winters create the same challenges. That range of experience means we approach every Daly City wall project with firsthand knowledge of what this coastal climate and these soil types actually do to a retaining structure over time - not just what textbooks say.
Call or fill out the contact form and tell us what you are dealing with - a sliding slope, a failing wall, or a yard you want to level. We respond within one business day and schedule a free on-site visit.
We walk your property, assess the slope, soil, and access, and tell you upfront whether a permit or engineer is needed. You get a written estimate covering excavation, wall type, drainage, and any permit fees.
For walls over four feet, we submit the permit application to the Daly City Building Division and coordinate with a licensed engineer for the stamped plan. This step typically adds two to four weeks to the start date.
The crew excavates, pours the footing into stable soil, builds the wall, packs gravel drainage behind it, and installs drainage pipe at the base. Backfill and site cleanup happen once the concrete has set.

(650) 587-4965We size footings, drainage, and wall thickness specifically for Daly City's expanding clay soils and the water pressure that builds up during the rainy season. A wall designed for a dry inland lot will not last the same way here.
We manage the building permit application with the City of Daly City Building Division and coordinate engineer stamping for walls over four feet. You get a clear timeline upfront - no permit surprises partway through the job.
Every wall we build includes gravel backfill and a perforated drainage pipe at the base. The Portland Cement Association identifies drainage as the single biggest factor in retaining wall longevity, and we treat it that way.
Many Daly City homes from the 1950s and 1960s sit on small lots with limited side clearance. We plan for access constraints before we start, so the project does not stall because a truck cannot get close enough to pour.
Every retaining wall we build is designed for the actual site - not a generic plan copied from a flat lot somewhere else. If you want to read more about retaining wall standards, the Portland Cement Association publishes good homeowner-facing guidance on drainage and footing depth that aligns with how we build.
