Hiring plumbers in Fairfax County

In Virginia, a contractor needs a DPOR licence for any job worth more than $1,000, and the licence class caps the size of a single job: Class C under $30,000, Class B under $150,000, Class A above that. Plumbers must also have a master tradesman licence behind the contractor licence. (Va. Code § 54.1-1100) Check the status, class and specialty of any business on DPOR’s License Lookup, or read how to check a contractor’s licence.

Virginia requires a licensed contractor to give you a written contract for residential work before work starts. Permits come from the local building department, and DHCD’s directory of local building officials says who to ask. Replacing a water heater has its own rules: do you need a permit to replace one.

On Loclis you describe the job once, licensed businesses send a price or offer to see it first, and nothing is charged until you book. How it works.
