“We had a steep slope in our backyard that was eroding badly, and Denver Retaining Wall built us a beautiful segmental block wall about 40 feet long. The crew finished in just three days and left the site cleaner than when they started. Best decision we made for our property.”
Retaining Wall Installation
“Needed a natural stone retaining wall built along our garden bed, and these guys absolutely nailed it. The craftsmanship is incredible, you can tell they really cared about making it look right, not just functional.”
Boulder & Natural Stone Walls
“Our old timber retaining wall was leaning pretty bad and we were worried it would collapse. Denver Retaining Wall came out, assessed the damage, and got it stabilized and reinforced in about a week. Really professional team, and they explained everything as they went. I'd use them again in a heartbeat.”
Retaining Wall Repair
“Had them pour a concrete retaining wall along our driveway, 12 feet wide and 4 feet tall. They showed up on time, the work was done right, and honestly my only tiny complaint is they could've given me a heads-up about the dust, but that's minor. Really solid job overall.”
Concrete Retaining Walls
“Our backyard wall was literally about to fall over, it was scary. These guys came out same day for the estimate and had it fixed within two weeks. The wall is straight again and looks brand new. Can't thank them enough for the peace of mind.”
Leaning & Collapsed Wall Repair
“We wanted to replace an old crumbling wall with something that would last. Denver Retaining Wall built us a gorgeous natural stone retaining wall using local Colorado stone, it looks like it belongs there and adds so much character to our property. Four-person crew worked efficiently and the whole project took about 10 days. Highly recommend.”

Denver Retaining Wall is the trusted local contractor for homeowners searching for retaining wall services near me across Denver, Aurora, Lakewood, Arvada, and Westminster. Whether you need a new Retaining Wall Installation on a sloped yard, urgent Retaining Wall Repair, or complete replacement of a failed structure, our network of licensed, insured local contractors brings decades of Front Range experience to every project. We specialize in the unique challenges of Denver's terrain: the expansive bentonite clay soils that swell and shift with moisture, the freeze-thaw cycles that crack and heave foundations, and the sloped residential lots that demand proper drainage and reinforcement to stay stable year after year.
From the Victorian brick neighborhoods of Capitol Hill and the Highlands to the 1970s tri-levels with walkout basements in Lakewood and Bear Valley, Denver homeowners depend on retaining walls to hold back soil, protect driveways, and prevent erosion. The problem is simple: most wall failures stem from one root cause: saturated backfill and inadequate drainage. When water builds up behind a wall, hydrostatic pressure mounts, soil expands, and even a well-built structure can lean, crack, or collapse. That is why we design every wall with proper weep holes, French drain systems, and gravel backfill to keep water moving away from the wall face. Call (983) 955-0165 today for a free estimate on your Denver retaining wall project.
Retaining wall repair is our highest-priority service because a failing wall is a safety and property risk that worsens every season. The most common failure we see is a leaning or bowing wall, which happens when hydrostatic pressure from saturated backfill pushes against the wall face faster than the structure can resist. In Denver's expansive clay soils, this pressure is relentless: spring snowmelt and summer cloudbursts soak the soil, clay minerals swell, and the wall bows outward. If drainage is clogged or missing entirely, the problem accelerates. A slight lean this year becomes a severe bow next year, and a severe bow becomes a collapse after a heavy rain or during spring thaw. The fix requires excavation, installation or repair of French drain systems and weep holes, and often geogrid reinforcement or tieback anchors to re-stabilize the structure.
Cracking and bulging are equally serious warning signs. Horizontal cracks across a concrete or block wall, or bulges in the face, signal that soil pressure is overwhelming the wall's strength. Sinking and settling occur when the footing was undersized or compaction was poor during installation, allowing the wall to subside unevenly and crack. Collapse after heavy rain is the most dramatic failure: a wall slides or tips because drainage failed, the footing eroded, or the soil beneath gave way. Every one of these scenarios can be prevented or halted with prompt professional repair. The longer you wait, the more expensive the fix becomes. Leaning & Collapsed Wall Repair is our specialty. Call (983) 955-0165
We also handle Retaining Wall Replacement when repair is not enough. If a wall is severely compromised, has moved more than an inch or two, or has failed multiple times, replacement is often the most reliable long-term solution. We remove the failed structure, correct the underlying site and drainage conditions, and build a new wall engineered to handle Denver's climate and soil for decades to come.
Denver Retaining Wall builds with the materials best suited to your site, budget, and aesthetic. Block & Segmental Retaining Walls (SRW) using brands like Allan Block, Versa-Lok, and Keystone offer strength, durability, and clean lines, and are ideal for taller walls because they accept geogrid reinforcement easily. Concrete Retaining Walls, whether poured monolithic or built from reinforced CMU, provide maximum strength and are often required for high-load surcharge applications like driveways or structures. Boulder & Natural Stone Walls using the pink and buff moss rock and sandstone flagstone stacks traditional to Denver neighborhoods blend beautifully into hillside lots and established landscapes. Timber Retaining Walls and Railroad Tie Wall Replacement are common in older Denver homes, though we advise that timber has a finite lifespan in Colorado's dry climate and freeze-thaw cycles, typically 15 to 25 years depending on wood species and drainage. Regardless of material, every wall we build includes proper drainage with weep holes, filter fabric, and gravel backfill, plus geogrid reinforcement for walls above four feet or under surcharge load.
Retaining wall pricing in Denver typically ranges from a cost-per-square-foot of wall face, but that figure varies widely based on material choice, wall height, site drainage and excavation requirements, access, and whether engineered drawings are needed. A simple segmental block wall on level ground with good drainage will cost less per square foot than a tall poured concrete wall on a steep slope with poor soil and extensive excavation. Final pricing depends on site conditions, so we always recommend requesting a free estimate from a licensed contractor who can walk your property, assess the soil and slope, and provide an accurate quote. Visit our pricing page for typical cost ranges and project examples, and call (983) 955-0165 to schedule an on-site evaluation.
Retaining wall permits and engineering requirements vary by city and county across the Denver metro area. In most jurisdictions, walls above roughly four feet in height (measured from the footing) require a building permit, and walls that support a surcharge such as a driveway, deck, or structure almost always do. Taller walls or walls on steep slopes typically require engineered drawings prepared by a licensed engineer to ensure the design meets local codes and soil conditions. However, thresholds, setback rules, and property-line requirements differ between Denver, Aurora, Lakewood, Arvada, Westminster, and surrounding towns. We always obtain the necessary permits and coordinate with local building departments on your behalf, but it is your responsibility to verify requirements before starting. Requirements vary, so always verify with the Denver building or planning department (or your local city or county authority) before starting your project. Contact us for a free estimate and we will help you understand what your specific project will need.
