Plumbing and HVAC in Diamond Bar, CA 91765
39 providers listed in Diamond Bar, CA 91765 for Plumbing and HVAC: 14 companies and 25 independent tradespeople. 39 licensed.
Every business here holds a current licence, shown on the listing so you can check it yourself.
Some states license the person rather than the firm (master plumbers, gas technicians), which is why independent tradespeople have their own tab.
A licensed individual trading under their own name. Well suited to smaller jobs. Ask to see proof of liability insurance and workers' compensation before work starts, since sole licensees are not always required to carry either.
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.
