“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 retaining wall contractor for homeowners across the Denver metro area searching for retaining wall contractor near me. Whether you need Retaining Wall Installation on a sloped residential lot, urgent Retaining Wall Repair, or complete wall replacement, our network of licensed, insured local contractors delivers proven results in Denver, Aurora, Lakewood, Arvada, Westminster, and surrounding areas. We specialize in the unique challenges of Front Range hillside properties, where expansive bentonite clay soil, freeze-thaw cycles, and heavy spring snowmelt create conditions that demand expert wall design and drainage.
The most common reason retaining walls fail in Denver is not structural defect but rather poor or failed drainage. Saturated backfill exerts hydrostatic pressure against the wall face, causing it to lean, bow, crack, and eventually collapse. We build every wall with proper drainage aggregate, filter fabric, and weep holes to manage water and extend wall life by decades. If your wall is already showing signs of trouble, call (983) 955-0165 for a free estimate.
A leaning or bowing retaining wall is not a cosmetic issue. It is a sign that hydrostatic pressure from water-saturated soil is pushing against the wall face, and without intervention, that pressure only increases with each freeze-thaw cycle and heavy rain. In Denver's high-altitude climate, water trapped behind a wall expands when it freezes, forcing the wall outward. If the wall also lacks proper weep holes or a French drain system, groundwater accumulates behind the wall face, multiplying that outward force. What begins as a slight lean becomes a noticeable bow within one or two seasons, and a bow becomes a structural failure within months if left unrepaired.
Cracking, bulging, or partial collapse after heavy rain are equally urgent warning signs. These failures typically stem from one or more of four root causes: (1) hydrostatic pressure from clogged or missing drainage, (2) undersized or settling footing that allows the wall to sink and tilt, (3) inadequate soil compaction or geogrid reinforcement behind the wall, or (4) expanding clay soil that swells against the wall face and destabilizes the structure. Our Leaning & Collapsed Wall Repair service addresses each of these failure modes with proper diagnosis, drainage correction, and structural stabilization. The longer you wait, the more expensive the repair becomes and the greater the risk to your home, driveway, or yard. Call (983) 955-0165 today to schedule your wall inspection and free estimate.
Even walls that appear stable may be at risk. Slow sinking, minor cracks in block or stone, or a subtle increase in wall lean over a season are all early signs of drainage failure or footing settlement. Early intervention prevents catastrophic failure and preserves your property investment. Our licensed, insured contractors perform a thorough site assessment, identify the root cause of failure, and recommend the most cost-effective repair strategy, whether that is installing new drainage, reinforcing the existing wall, or full replacement.
We build retaining walls in the materials best suited to your site, budget, and aesthetic goals. Block & Segmental Retaining Walls (SRW), such as Allan Block and Versa-Lok systems, offer modularity, speed of installation, and excellent drainage when properly built with geogrid reinforcement for taller walls. Concrete Retaining Walls, whether poured monolithic or built from reinforced CMU, provide durability and clean lines, especially for driveway approaches and structural applications. Boulder & Natural Stone Walls showcase the beautiful pink and buff moss rock and sandstone characteristic of Denver's landscape tradition, though they require expert installation and internal drainage to perform well on hillsides. Timber Retaining Walls and Railroad Tie Wall Replacement are common in older Denver neighborhoods, but timber degrades over 20 to 30 years and often fails at the base where soil moisture accelerates rot. Regardless of material, every wall we build includes proper gravel backfill, filter fabric, weep holes, and batter (wall lean-back) to shed water and ensure long-term stability.
Retaining wall pricing in Denver is typically quoted per square foot of wall face and depends on several factors: material choice (block, concrete, stone, or timber), wall height, site drainage and excavation requirements, soil conditions, property access, and whether engineered drawings are required by your local jurisdiction. A simple segmental block wall on a level site with good access will cost less per square foot than a tall poured concrete wall on a steep slope with poor drainage and heavy clay soil. Final pricing depends on site conditions, and the only way to know your true cost is to have a licensed contractor visit your property and assess the work firsthand. Visit our pricing page for typical ranges in the Denver area, and request a free estimate from our team.
In most jurisdictions across the Denver metro area, retaining wall permitting requirements depend on wall height, location, and whether the wall supports a surcharge such as a driveway or structure. Commonly, walls over about four feet (measured from the footing) require a permit, but thresholds vary by city and neighborhood. Taller walls or walls supporting a surcharge often require engineered drawings prepared by a licensed engineer. Setback and property-line rules also apply and vary by jurisdiction. Many homeowners are surprised to learn that a permit is required for work they thought was routine landscaping, and conversely, some smaller walls may not require formal permitting at all. Because requirements vary significantly, always verify with the Denver building or planning department before starting your project. Our licensed, insured contractors are familiar with local codes and can guide you through the permitting process, but the final responsibility for compliance rests with you and your local authority.
