Utility Installation Services

Utility Installation in Williams • Flagstaff • Sedona

When it comes to underground utilities—water, sewer, storm-drain, power or

communications—having a dependable partner is critical.

At KG Contracting, we bring the same reliable, personal service to utility installation as we do with everything else. Whether you’re installing utilities for a new home in Williams, extending service at a Sedona cabin, or upgrading infrastructure near Flagstaff, we’ve got the know-how and the equipment to deliver safe, code-compliant results.

Why work with us?

  • Safety and code compliance – We stay current with local utility codes and permit requirements in Williams, Flagstaff and Sedona.
  • Single-source convenience – Instead of hiring separate contractors for trenching then restoration, you get one company (us) to handle end-to-end.
  • Respect for your property – Because we’re locally owned, we treat your land like we would our own: clean worksite, minimized disruption, and a clean finish.
  • Flexible scheduling – We understand remote or scenic locations (like Sedona or mountain‐terrain outside Flagstaff) may need special planning; we’re experienced in the region and responsive.
