Directory

Plumbing and HVAC

Plumbers, HVAC and gas contractors holding the trade licence for the work.

163,543 providers in 12,423 ZIPs Credentials differ by state and city, because the requirement itself does. Each listing says which one it holds.

Some states license the person rather than the firm (master plumbers, gas technicians), which is why independent tradespeople have their own tab.

Ordered by permits pulled, so businesses with a verified record of inspected work come first.

Badges come from public records, not from us or the business. Licence verified: an issued licence number and a city permit record name the same firm. Established: ten or more permits on record. Active this year: a permit dated in the last 12 months. A business without a badge may simply work where we hold no permit records.
