How to evaluate Black Diamond Supply

Before hiring Black Diamond Supply for lighting work in Phoenix, take a few minutes to verify their qualifications and confirm they are the right fit for your project. The right lighting for one homeowner may not be the right fit for another, so do the diligence up front.

Verify licensing and insurance

Confirm that Black Diamond Supply carries an active AZ contractor license appropriate for the scope of work, plus general liability and workers’ compensation coverage. Ask for the license number and look it up on the state board website. A lighting that hesitates to share these details is a red flag, regardless of how favorable their reviews look.

Get a written, itemized quote

Request a detailed written estimate that lists materials, labor, permit fees, timeline, and payment schedule. Itemized quotes make it possible to compare Black Diamond Supply side-by-side with other lighting options in Phoenix, and they protect you from scope creep once the work begins.

Ask about project experience

Ask Black Diamond Supply how many projects similar to yours they have completed in the last 12 months, whether they will be the primary on-site team or are subcontracting, and how they handle change orders. Request two or three local customer references and actually call them — reviews on Google are useful but a five-minute conversation reveals much more about how a lighting actually shows up.
