What is a trade contractor in Virginia?

A trade contractor is a licensed professional who performs specialized construction, repair, or installation work. In Virginia, the most common trade-licensed categories are plumbing, electrical, HVAC (heating, ventilation, and air conditioning), and roofing. Virginia DPOR (Department of Professional and Occupational Regulation) requires contractors performing work over $1,000 in value to hold a Class A or Class B contractor license. The license class depends on the contractor's annual project value: Class A is $120,000+ per year, Class B is $10,000 to $120,000.

Why Northern Virginia has strong demand for trade services

Northern Virginia is one of the highest-density, highest-income regions in the US. The directory focuses on 703 and 571 communities across Arlington, Alexandria, Fairfax, Falls Church, eastern Loudoun, Manassas, and Prince William. Demand drivers include: suburban housing density, four-season climate requiring both heating and cooling, mature homes that need replacement of major systems, and a steady stream of new construction in Loudoun and Prince William counties.

HVAC services and licensing

Virginia HVAC contractors need both a general contractor license (Class A or B) plus an HVAC specialty classification from DPOR. Services range from emergency repair ($80-$200 for a diagnostic visit) to full system replacement ($3,500-$7,500 for a furnace, $4,000-$10,000 for central AC). Look for NATE-certified technicians for complex installations. Smart thermostat installation and zoned HVAC are increasingly common in NoVA.

Plumbing services and pricing

Plumbing work over $1,000 in value requires a Class A or B plumbing contractor license. Standard pricing in Northern Virginia: water heater replacement $1,200-$3,500 (standard tank) or $2,500-$5,500 (tankless), sewer line repair $3,000-$15,000 depending on depth, repipe $5,000-$15,000 for a typical home, main water line replacement $3,000-$7,000. Most plumbers offer 24/7 emergency services at higher rates.

Electrical services and EV chargers

Virginia electrical contractors need a Class A or B electrical contractor license. Standard services: panel upgrade $1,500-$4,000, EV charger install $500-$2,500 (depends on panel capacity and distance), generator install $5,000-$15,000, whole-home rewiring $8,000-$25,000. Many NoVA electricians specialize in EV charger installation given the region's high EV adoption rate.

Roofing services and licensing

Roofing over $1,000 requires a Class A or B roofing contractor license in Virginia. Standard pricing: asphalt shingle replacement $7,500-$25,000 for a typical 2,000 sq ft home, metal roof $15,000-$50,000, slate or tile $25,000-$80,000. Many NoVA roofers specialize in storm-damage repair and insurance claim work.

How to verify a Virginia contractor license

Before signing any contract, verify the contractor's Virginia DPOR license at dpor.virginia.gov. The site shows the license status, classification, expiration date, and any disciplinary actions. Also check Virginia State Corporation Commission (cis.scc.virginia.gov) for the business registration, and Better Business Bureau for any complaints.

What to ask before signing

Get at least 3 written estimates for any major work. Ask: Are you licensed and insured (general liability + workers comp)? Who performs the work (employees or subcontractors)? What's the payment schedule (avoid more than 30% upfront)? What's the warranty on parts and labor? Is cleanup/hauling included? What's the timeline? Who pulls the permits?
