About this record

This page is a public summary of DLM Excavation & Construction Inc built entirely from government records — the Arizona Registrar of Contractors license file and building permits issued by jurisdictions across Arizona. PlumbIntel joins those sources so you can see, in one place, that a contractor is properly licensed and actively pulling permits under that license.

Everything here is factual and sourced: license status and dates come from the AZ ROC; permit counts, addresses, and values come from the issuing jurisdiction. We do not publish reviews, ratings, or unverified contact details — owner-provided updates always carry their source label. If you're a homeowner vetting a contractor, a lapsed license or a gap in permit history is worth a conversation before you sign.
