Local Business Description
API Services, founded by experienced Denver builders, brings decades of local construction expertise to every block and rock retaining wall project. Our journey began with custom homes in the metro area, evolved through multi-family and commercial project management, and is now dedicated to the specialized craft of retaining walls. Under the mentorship of my now-business partner, we learned that a correctly built wall is an investment that lasts for generations. That's why we focus solely on doing it right the first time, whether for a residential backyard or a commercial site for partners like Marriott and Howell Construction. We often correct walls improperly built by others, understanding that rework is costly and disruptive. For Denver homeowners and businesses, we provide durable, long-term solutions that transform and protect outdoor spaces.
Q&A
Why do so many retaining walls in Denver fail, and how do you prevent it?
In the Denver area, many walls fail because they aren't built to handle our soil conditions, freeze-thaw cycles, or proper drainage. Landscapers sometimes prioritize aesthetics over structural integrity. We prevent failure by using proper engineering principles, deep foundations, and quality materials suited for our climate. Our focus is on building a wall correctly from the start so it lasts for decades, not just a few seasons.
Can you build a retaining wall that also addresses lawn damage from tree roots?
Absolutely. A common issue in Denver homes is lawn damage and uneven ground from large tree roots. A professionally engineered retaining wall can help manage soil erosion and create level, usable spaces in your yard while working around or incorporating existing tree root systems. We assess the site to design a wall that solves the structural problem without harming healthy trees.
Do you work with both homeowners and commercial properties?
Yes, we serve both. While we often work directly with residential customers, our background in commercial project management means we're also a trusted partner for businesses and contractors. We have built walls for companies like Marriott and Ace Design and Construction, applying the same standard of quality and durability to every project, big or small.
