Summerlin South rises toward Red Rock on sloped lots where desert stone and terraced block walls turn hillside backyards into real living space. If your retaining wall is leaning, cracked, or failing after our monsoon rains, Las Vegas Retaining Wall knows exactly what's happening and how to fix it.

Homeowners in 89135 call us because we understand Summerlin South. Your lots are steep. Your soil traps water behind caliche hardpan. Your drip irrigation and sudden flash floods push hydrostatic pressure against walls that were never designed to handle it. We've repaired hundreds of block, boulder, and terraced walls in this neighborhood, and we know how to stabilize your slope before it takes your driveway or yard with it.

Retaining Wall in Summerlin South (89135)

Summerlin South sits on alluvial fans that rise steeply toward the Spring Mountains and Red Rock. Your neighborhood is built on terraced lots with 2000s two-story homes, raised yards, and hillside backyards that demand solid retaining walls. The terrain here is unforgiving. You've got collapsible desert soil that settles when it gets wet, caliche hardpan that stops drainage cold, and dry washes that flood hard and fast during monsoon season. Most walls in Summerlin South are split-face CMU block, segmental block around pools and raised planters, or stacked desert stone and boulder walls. They fail when water gets trapped behind them, when soil expands and contracts with irrigation cycles, or when a monsoon pushes thousands of gallons of runoff downslope in minutes.

We've been serving Summerlin South and the Las Vegas area for years. We know the soil conditions, the drainage challenges, and the permit requirements for walls in Clark County. We bring engineered solutions to steep lots and terraced yards where a standard wall simply won't hold.

Our services in Summerlin South

How a Job Works in Summerlin South

We start with a free on-site assessment. We walk your property, look at the slope, check for water pooling or drainage problems, and ask about what happened (cracks after rain, visible lean, or a wall that's been sinking). We take photos and measurements, and we give you a realistic estimate and timeline on the spot. Most jobs in Summerlin South require a permit because of wall height and the surcharge from driveways or structures, so we'll coordinate that with the Clark County building department and handle the paperwork.

The work itself depends on what you need. If it's a repair, we may inject grout, add drainage, or rebuild a section. If it's a full replacement, we excavate, set proper footing below frost depth, install drainage tile to stop hydrostatic pressure, and rebuild with block, stone, or segmental material that matches your yard. Summerlin South lots are tight, so we plan access carefully and may use smaller equipment or hand crews to protect your landscaping and neighbors' property lines.

When we're done, we haul away all debris, backfill and compact, and walk through the finished work with you. Your yard is clean and your wall is built to last.

Pricing in Summerlin South depends on size, access, soil condition, and what you're asking us to do. A block or segmental wall replacement typically runs $35 per square foot. Boulder and natural stone walls start at $25 per square foot. Timber walls are $20 per square foot. Repairs on existing walls start at $1,500 and go up based on the damage and whether drainage work is needed. If your wall has failed and needs full replacement with engineered drainage, budget $2,500 to $5,000 or more, depending on linear footage and height. Slope stabilization and erosion control starts with a free estimate. The best way to know what your job will cost is to call us at (725) 726-4860 and get an on-site assessment. We'll give you a firm price before we start work.

My block wall in Summerlin South is leaning outward and I see cracks after every rain. What's happening?
Hydrostatic pressure. Water is pooling behind your wall because drainage is clogged or missing. Desert soil holds moisture against caliche hardpan, and that pressure pushes the wall outward. You need drainage installed behind the wall, and depending on how far it's leaning, you may need to rebuild it with proper footing and a drainage system. This is urgent because a leaning wall can collapse suddenly, especially during monsoon season. Call us at (725) 726-4860 for an emergency assessment.
We had heavy rain last month and our terraced retaining wall started to slide. Can you help with an emergency?
Yes. We respond to emergency wall failures and slope failures in Summerlin South and the Las Vegas area. Sliding and settling after heavy rain is usually caused by water saturation in collapsible soil or hydrostatic pressure behind the wall. Call us immediately at (725) 726-4860. We'll get a crew out to assess the damage, stabilize the slope if needed, and give you options for repair or replacement. Don't wait, because a sliding wall can take your driveway or yard with it.
How much does it cost to replace a retaining wall in Summerlin South?
Full replacement of a block or concrete wall runs about $35 per square foot. A boulder or natural stone wall is roughly $25 per square foot. A timber wall is around $20 per square foot. A typical 30-foot wall, 4 feet tall, might run $4,200 to $4,500 depending on material and site access. Costs go up if you need engineered drainage, if the lot is steep or tight, or if the old wall has to be demolished first. The best way to know is to call (725) 726-4860 for a free estimate.
Do I need a permit for a retaining wall in Summerlin South?
Usually yes. Clark County requires a permit for most retaining walls taller than about 4 feet measured from the footing, or any wall that supports a surcharge like a driveway, structure, or pool. Engineered drawings may be required for tall or tiered walls. We handle the permit process and coordinate with the Clark County building department. Always verify current requirements with the local building department because thresholds can change, but we'll make sure your wall meets code.
My neighbor and I are not sure where the property line is. Can we build a retaining wall on it?
No. Retaining walls must be set back from the property line according to Clark County setback rules, and a wall that straddles the line can create legal problems with your neighbor. Before we start any work, we recommend you have a professional surveyor mark the property line. Once you know where it is, we can build your wall on your side with proper setback. If you're in an HOA community in Summerlin South, you'll also need HOA approval. We can help coordinate that process.
Are you insured for work at my Summerlin South home?
Yes. Las Vegas Retaining Wall is fully insured with general liability and workers' compensation coverage. We protect your property and our crew on every job. You can work with confidence knowing that we carry the insurance you need.
It's summer in Las Vegas and my drip irrigation keeps running. Is that bad for my retaining wall?
Yes. Overwatering is one of the top reasons walls fail in Summerlin South. Constant moisture softens desert soil, triggers settlement and expansion, and pushes water against your wall's drainage system. In summer, check your irrigation timer and make sure it's not running too long or too often. If your wall is old and lacks proper drainage, that standing water will eventually cause leaning or cracking. If you're seeing signs of wall failure, call us at (725) 726-4860 for a free assessment. We can install or repair drainage to protect your wall and your yard.
