Phoenix insulation licensure at a glance

52 active ROC insulation licenses are registered in Phoenix. Every Arizona license carries a scope, and it is a legal boundary rather than a size tier: 42 of Phoenix's licenses are dual scope (residential and commercial work) and 10 residential-only, while commercial-only licenses never appear on these pages at all - they do not permit residential work in Arizona. Tenure is what these pages rank on, and Arizona's issue dates are real and filled on every record: the median Phoenix license has been held 5 years, the longest-standing since 1987, and 3 (5.8%) have been held 25 or more years. The posting list carries no insurance, no bond and no phone for any licensee - Arizona requires a license bond by statute but does not publish it, so we never show one, never claim one, and never rank on one. ROC's contractor search cannot link straight to a record, so every listing above shows its number for you to paste into ROC's contractor search. How we verify.

Insulation Contractors in Phoenix: common questions

How many licensed insulation contractors are there in Phoenix?

52 active ROC insulation licenses are registered in Phoenix. 52 Phoenix-registered companies passed our license verification, and the 8 on this page are the top-ranked of those. Only licenses ROC posts as Active, carrying a residential or dual scope and unexpired at our data date, are listed.

What does the scope on an Arizona insulation license mean?

Arizona's scope is a legal boundary, not a size tier: a commercial-only license does not permit residential work, so commercial-only contractors never appear on these pages at all. 42 of Phoenix's 52 licenses are dual scope (residential and commercial) and 10 are residential-only.

How do I check an insulation contractor's license in Arizona?

Every listing above shows its ROC license number. ROC's contractor search cannot link straight to a record, so open it and type the number in: it shows the class, scope, status and expiration. The median Phoenix license has been held 5 years, and the longest-standing dates to 1987.
