Questions and Answers
My irrigation valves keep failing, and my rock garden is shifting. Is this common in Longmont, and can you help?
Yes, these are frequent challenges for Longmont homeowners. Our clay-heavy soils and freeze-thaw cycles can put stress on irrigation systems and hardscapes. We diagnose and repair faulty valves, often recommending system upgrades for durability. For shifting rock gardens or retaining walls, our construction expertise ensures proper drainage and stable foundations to prevent future movement, keeping your landscape secure and functional.
Do you handle the entire process for a new landscape, from design to construction?
Absolutely. As a full-service company, we manage every step. Our team provides custom landscape design, then handles the construction or installation—including patios, walkways, retaining walls, and irrigation systems. We also offer ongoing maintenance, shrub care, and seasonal services. This integrated approach ensures your vision is realized with cohesive planning and expert execution.
Why is backflow testing important for my irrigation system, and do you offer it?
Backflow testing is crucial for protecting Longmont's drinking water from contamination by your irrigation system. It's also a requirement for many local water providers. As a company licensed through the ASSE and the State Health Department, we are certified to perform this annual test. We ensure your system complies with all local regulations, providing you with the necessary documentation for your water district.
