Precision Trenching For Utility Infrastructure
Utility trenching is at the core of every successful underground infrastructure project, forming the backbone for power, gas, telecom, and lighting systems. At Windsor Underground, we bring decades of hands-on experience, technical knowledge, and specialized equipment to execute safe, efficient trenching across varied job site conditions—from compact urban zones to expansive desert terrain. Our skilled crews understand how to balance production efficiency with strict compliance standards, ensuring each trench is cut to spec and aligned with engineering and utility requirements. Whether it’s a shallow run for streetlight conduit or a deep trench for multiple duct banks, we deliver excavation, conduit placement, and backfill services that prioritize safety, environmental impact, and long-term infrastructure reliability.
Our trenching services are integral to both new construction and retrofitting projects, supporting utility expansions, upgrades, and relocations with minimal disruption to surrounding infrastructure. We maintain full adherence to municipal and utility regulations, including trench width, depth, bedding material, and separation between conduits. ADA-compliant crossings, erosion control, and surface restoration are carefully planned and executed. Additionally, we coordinate with APS, SRP, Southwest Gas, and local inspectors to ensure trench inspections are completed efficiently and utility tie-ins proceed without delay.
Built To Serve Complex Utility Projects
Whether you’re installing telecom lines in a tight urban footprint or trenching for gas sleeves in open desert terrain, we deliver high-performance trenching tailored to your site and scope. Our field crews are trained in OSHA standards and work closely with GCs, engineers, and inspectors to minimize delays and avoid conflicts.

What We Handle In Utility Trenching
Our Trenching Process
We use a systematic trenching process to ensure safety, accuracy, and minimal site disruption. Our team begins each project with utility locates, pre-marking of trench paths, and coordination with utility providers to prevent conflicts. We follow engineered plans precisely, maintaining required depths, conduit separation, and compaction standards throughout the excavation. This methodical approach keeps projects moving efficiently while meeting all inspection and compliance requirements.
