Do Landscapers Build Retaining Walls?
If you typed “retaining wall builders near me” after a summer rain carved a rut in your yard, you’re in the right place. Many homeowners start with one simple question: do landscapers actually build retaining walls, or do you need a separate contractor? The short answer is yes — many landscapers do build retaining walls. The long answer is that not all walls are the same, and not all landscapers have the training, equipment, or licensing to build a wall that stays put in Asheville’s clay soils and mountain slopes.
This guide breaks down who should build your wall, what matters in design and construction, how local codes shape the work, and what to expect from a professional site visit. You’ll see where a basic garden wall ends and a true retaining structure begins, plus what that means for cost, timeline, and longevity. If you live in Asheville, Woodfin, Weaverville, Fairview, Candler, Fletcher, or Black Mountain, this will help you pick the right team for your property and your budget.
Landscapers vs. Retaining Wall Specialists
Landscaping is a wide field. Some companies focus on mowing and planting. Others handle hardscapes such as patios, steps, and walls. Within that group, a subset specializes in retaining structures that manage soil and water.
A landscape crew that excels at planting can build a short raised bed with landscape blocks and topsoil. That is landscaping. A wall that holds back ten tons of saturated clay next to your driveway is a retaining structure. That is closer to light civil work. The difference shows up in the base preparation, drainage design, and geogrid reinforcement. It also shows up in the permit process and liability.
In Asheville and Buncombe County, many walls above a certain height require engineering and permits. Even smaller walls can fail if the groundwater is not managed. A real builder understands soil pressure, frost movement, and surcharge loads from parked vehicles or slopes above the wall. If your wall will hold back grade, support a patio, or sit near a property line, you want a contractor who can show plans, calculations when required, and a record of successful installs in Western North Carolina soils.
When a Landscaper Is Enough — And When You Need a Specialist
A small garden wall that stands 18 to 24 inches tall often falls within the comfort zone of a general landscaper. These decorative walls frame beds, edge patios, or level a small spot for a grill. They typically use dry-stack concrete blocks with a compacted gravel base and drain stone backfill. For low height and no surcharge, that can be fine.
Once you pass 30 to 36 inches, stakes rise quickly. Taller walls need more embedment, cleaner drainage, and usually geogrid. If a driveway, parking pad, or shed sits behind the wall, the wall sees extra load. Hillside yards in Kenilworth, West Asheville, and North Asheville often include slopes with perched water. That water adds hidden pressure. This is where a retaining wall specialist makes a real difference.
If you are unsure, call for a site evaluation. A good contractor will measure slopes, probe soils, and ask about water patterns after rain. If someone shows up ready to “stack some blocks” without talking about base depth, pipe outlets, or grid layers, keep looking.
The Asheville Factor: Soil, Water, and Freeze-Thaw
Most of Asheville rides on red clay, rocky subgrades, and mixed fill from older construction. Clay holds water. When clay gets wet, it swells and exerts lateral pressure. In winter, freeze-thaw cycles move shallow soils. All of this affects wall design.
In Biltmore Forest and North Asheville, we often find deep clay over weathered rock. On steeper sites in Haw Creek or Riceville, shallow soils sit atop fractured rock with springs that wake up during heavy rain. We have rebuilt many walls that lacked proper drainage. The pattern is common: bulge at the base, leaning forward, often within two to three years.
You manage Asheville conditions by over-preparing the base, building generous drainage, and directing discharge to daylight. That means compacting a deep crushed stone footing, installing a perforated pipe with at least 1 percent slope to an outlet, and using washed stone and fabric to keep fines out of the drainage zone. If grid is needed, you size it to the wall height and soil properties, and you lay it level on compacted lifts. Skipping any of these steps invites a redo.
Materials: Which Retaining Wall Type Fits Your Yard
You have several options, each with strengths and trade-offs. Here is how they play out in real Asheville yards.
Segmental concrete block walls are the most common. They use interlocking blocks with a gravel base and stone backfill. They flex slightly, which helps in freeze-thaw. They install faster than mortared masonry. They pair well with geogrid for taller walls. They come in many colors and textures, which fits Montford and West Asheville aesthetics. Price ranges depend on block choice and wall height.
Timber walls still show up in older homes, especially in South Asheville and Oakley. New pressure-treated timbers work for short walls and tight access sites. They can look warm with a natural yard. The downside: wood is organic. Even treated timbers will age, check, and creep. Drainage needs are the same as any wall. If you want a 15-year solution and like the look, it can fit. For longer life, concrete or masonry wins.
Natural stone dry-stack walls fit historic homes and mountain settings. Good ones take skill and time. Stone walls can last decades if they have a proper footed base and drainage. With poor drainage, they bulge. Stone is heavier to handle, so access and staging matter. For a visible front yard in Grove Park or Norwood Park, stone can be worth the investment.
Poured concrete and CMU masonry walls suit tight footprints and walls that need high strength. These usually require engineering and a concrete footing below frost depth. They’re excellent for structural needs and for supporting hardscapes like elevated patios. We often face them with stone or veneer block to soften the look.
Gabion baskets perform well on creek banks and steep slopes where water flow is constant. They drain freely and resist scour. They’re industrial in appearance. For a modern home or a hidden slope, they’re practical.
What “Good” Construction Actually Looks Like
A solid retaining wall in Asheville is built from the ground up — literally. The base is the foundation. We dig down to firm subgrade, often deeper than clients expect. For a typical 3 to 4 foot block wall, we set a 6 to 8 inch thick layer of compacted crushed stone as the footing. We embed the first course below grade, commonly 10 percent of wall height. That embed helps resist sliding and helps with frost.
Drainage sits right behind the wall. Clean, angular stone backfill gives water a clear path down to a perforated pipe. That pipe slopes to daylight or to a drywell if the site calls for it. We wrap stone in a geotextile fabric to keep fines from clogging the drainage zone. On walls above about 3 feet, we usually include geogrid layers at set intervals. The grid extends back into the retained soil, turned flat and tensioned, to create a reinforced soil mass. Each soil lift gets compacted to spec. The wall and soil act together, which is the point.
Capping and finishes matter, too. A smooth, level cap keeps water from running into the face joints. We shape the grade above the wall to shed water away. Surface runoff control is as important as the pipe behind the wall. If your downspout dumps behind your wall, you are feeding a problem.
Permits, Codes, and When an Engineer Steps In
Local rules exist to keep walls safe. In Asheville and Buncombe County, walls over certain heights, or walls supporting slopes, structures, or parking, can require a permit and stamped drawings. Many municipalities in our area use 4 feet as a common threshold, measured from bottom of base to top of wall, but conditions matter. If there is a surcharge load — like a driveway or a steep bank — an engineer may be required even for shorter heights.
We coordinate with local building and zoning staff to make sure your project complies. On infill lots in West Asheville, setbacks and drainage easements often affect wall placement. On hillsides in Arden or Fairview, erosion control rules can apply. A quality contractor handles this with you. It avoids red tags and rebuilds.
Cost Ranges in Asheville: What Drives Price
Homeowners usually ask for a ballpark number. That’s fair. For segmental block walls in the Asheville area, many projects land in a wide range based on height, access, material choice, and engineering needs. Small decorative walls may start in the low thousands. Structural walls that stand 3 to 6 feet tall often fall in the mid to upper four figures or into five figures, especially with steps, curves, or tight access that requires hand work. Engineered walls over 6 feet, walls with deep grid, or walls next to driveways or buildings can run higher due to design, permits, and the volume of stone.
Access changes everything. If we can bring a skid steer to the spot, we move faster and save you money. If we have to hand-carry block down a set of stairs in Montford, that adds labor. Soil conditions also matter. Wet clay needs more excavation and more stone. Bedrock close to the surface can slow footing prep but improves bearing. During a site visit, we’ll flag these factors so you can plan with real numbers, not guesses.
Lifespan and Maintenance
A well-built segmental wall with proper drainage should last decades. We commonly see 20 plus years when base, backfill, and water management are correct. Timber walls usually last a shorter window. Stone dry-stack walls can run much longer with good drainage.
Maintenance is simple but important. Keep surface water away from the top of the wall. Keep weep holes or pipe outlets clear. Do not let mulch clog the drainage gravel. Avoid placing heavy loads near the wall edge unless the wall was designed for it. If you notice bulging, cracking caps, or sinkholes along the top backfill, call before it worsens.
Safety and Liability: Why Construction Standards Matter
A retaining wall holds back soil that weighs about 100 to 120 pounds per cubic foot when wet. That adds up fast. If a wall fails next to a sidewalk or driveway, people and property are at risk. Insurance carriers look at these risks after an incident. Using correct base depth, grid, and drainage is not optional.
We have replaced walls built with little more than a couple inches of gravel and a wish. They looked fine for a year. The first freeze-thaw cycle and a few heavy storms shifted them out. The fix cost more than building it right the first time. Ask your contractor about compaction equipment, grid brands, pipe size and outlet location, and embedment depth. Clear answers mean they have done this before.
Choosing the Right Team in Asheville
Search habits have shifted. Many homeowners open a phone and search retaining wall builders near me. That is a start, but your shortlist should include contractors who show real retaining wall projects in Asheville neighborhoods and can speak about local soils. Look for photos of walls at different heights, not just garden edges. Ask for references you can drive by in your part of town.

We are used to tight city lots, steep driveways, and mountain weather. We coordinate permits, work with engineers when required, and keep job sites clean so neighbors stay friendly. If you want a team that treats your yard like a system — soil, water, access, aesthetics — we’re a call away.
What to Expect During a Site Visit
The first visit should feel like an assessment, not a sales pitch. We start by walking the site with you and asking where water goes in a storm. We check slopes with a level or laser and probe soils with a rod. We note utilities, trees, and access routes. If you want a patio above the wall or steps through it, we sketch that into the plan so the wall supports the use, not just the dirt.
We discuss materials with samples or photos and talk through budget tiers. Some clients choose a simple straight run with a textured block in a neutral color. Others go with a curved face, integrated steps, and a cap that matches the patio. We price both so you can weigh value, not guess.
If the wall likely needs engineering, we explain the process and timeline. On many projects, the design phase runs one to three weeks depending on complexity. Construction can take a few days to a couple of weeks, again based on height, access, and weather.
Common Mistakes to Avoid
We see the same failure points in Asheville year after year. Skipping drainage is the top culprit. Backfilling with native clay presses water against the wall and loads it up during storms. Thin bases are the next issue. A shallow base settles and tips forward. Lack of geogrid on tall walls is another. Grid feels invisible, so budget cutters try to delete it. The wall will tell on them later.
Another mistake is water discharge at the wrong place. A pipe that ends behind a fence with no daylight outlet will clog and back up. We plan where water goes before we set the first block. Sometimes that means adding a catch basin or tying into an existing drain. It’s a small line item that saves a lot of trouble.
Finally, walls near property lines need care. Setbacks and neighbor grading can trigger disputes. We survey or measure carefully and talk to neighbors in advance when work impacts shared areas.
A Few Asheville Case Notes
A client in West Asheville had a leaning timber wall along a driveway. The wall was about 4 feet tall, with a truck parked behind it daily. No drainage, no embedment. We replaced it with a reinforced block wall, two layers of geogrid, a 12 inch drainage zone, and a pipe to daylight at the street curb cut. The wall is straight years later, and the driveway Functional Foundations edge no longer cracks.
In Kenilworth, a homeowner wanted a flat play area for kids on a sloped backyard. We built a tiered pair of 3 foot walls with a 6 foot terrace between them, each with drainage and grid. Terracing reduced the pressure on any single wall, kept us under the permit threshold for each, and created a safe lawn. The family got a usable yard without a fortress.
In Candler, a small creek flanked a backyard. Erosion ate at the bank every storm. A gabion solution stabilized the slope and stayed within a narrow footprint. It’s not a showpiece, but it solved the problem and protected the yard.
Eco and Aesthetic Considerations
Retaining walls can support native plantings and stormwater goals. We often include a planting shelf behind or between tiers, which helps soften the structure and improves water infiltration. Using permeable caps or directing downspouts to rain gardens reduces runoff behind the wall. For aesthetics, we match block color to house stone or trim. In historic areas, we keep forms simple and lean on textures that age well.
Lighting is a small upgrade with big impact. Low-voltage cap lights or step lights improve safety and extend outdoor use. We run conduit during the wall build so you aren’t cutting later.
Timing Your Project
Asheville’s build season is year-round, but winter and early spring are ideal for structural work because vegetation is dormant and schedules are more open. Heavy summer rains can slow excavation on clay sites. If you aim for a spring patio, plan the wall in late winter. Permits and design have lead times, and block supply can fluctuate during peak months.
How We Price and Propose
Our proposals spell out base depth, backfill type, pipe size and outlet, grid layers with lengths, and cap details. You see the plan, not just a lump sum. We include allowances for rock excavation if a site suggests it, so surprises are handled fairly. Change orders are rare when the scope is clear at the start.
If another quote looks far cheaper, compare the spec details. If grid and drainage gravel are missing or undersized, that cheap wall becomes expensive in a few seasons.
