Class A Licensed Plumbing — Annandale & Fairfax County
Residential • Commercial • Emergency 24/7
Your Trusted Plumber in Annandale, Virginia
Annandale is one of Fairfax County's most established communities — a dense, diverse neighborhood where homes range from mid-century ramblers built in the 1950s and 1960s to newer townhomes and condominiums along the Little River Turnpike corridor. That mix of housing stock means plumbing systems of every age and material: galvanized steel supply lines in older homes that are long overdue for replacement, cast iron drain stacks that have corroded over decades, and modern PEX systems that still need a licensed hand when something goes wrong.
The Professor Plumbers has been serving Annandale and the surrounding Fairfax County communities with Class A licensed plumbing work. We understand the specific challenges that Annandale homeowners face — hard Fairfax County water that accelerates scale buildup in water heaters and supply lines, older homes with original plumbing that was never updated, and the high cost of water damage in a market where home values demand that repairs be done correctly and to code. We pull Fairfax County permits on every job that requires one, protecting your home's resale value and your homeowner's insurance coverage.
When you call The Professor Plumbers at (571) 632-6151, a real person answers — not a voicemail. We dispatch licensed technicians in fully stocked service trucks, and we provide upfront flat-rate pricing before any work begins. No surprises on the invoice. No subcontractors. No shortcuts.
Residential Plumbing Services in Annandale VA
From the oldest galvanized-pipe ramblers near Ravensworth to newer construction off Braddock Road, The Professor Plumbers handles every residential plumbing need in Annandale with the same Class A licensed standard of work.
Water Line Replacement
Annandale's older homes frequently have original galvanized steel supply lines that have corroded from the inside out, reducing water pressure and contaminating drinking water. We replace full water lines from the meter to the house using modern PEX or copper, pulling Fairfax County permits and restoring full pressure and water quality.
Drain Cleaning & Hydro-Jetting
Slow drains and recurring clogs in Annandale homes are often caused by decades of grease, soap, and mineral buildup in cast iron or old PVC drain lines. We clear blockages with professional hydro-jetting and camera inspection, finding the root cause rather than just pushing the clog further down the line.
Water Heater Installation & Repair
Fairfax County's hard water is hard on water heaters — sediment buildup shortens tank life and reduces efficiency. We install, repair, and replace tank and tankless water heaters from all major manufacturers, and we flush and service existing units to extend their service life.
Emergency Plumbing
Burst pipes, sewer backups, and gas line emergencies don't wait for business hours. The Professor Plumbers dispatches licensed technicians to Annandale 24 hours a day, 7 days a week — including weekends and holidays. One call to (571) 632-6151 and help is on the way.
Toilet, Faucet & Fixture Service
Running toilets, dripping faucets, and failing fixtures waste water and drive up Fairfax Water bills. We repair and replace toilets, faucets, showerheads, shut-off valves, and supply lines throughout Annandale homes — same-day service available for most fixture calls.
Sewer Line Inspection & Repair
Annandale's mature tree canopy is beautiful — and a constant threat to sewer lines. Root intrusion is one of the most common causes of sewer backups in older Fairfax County neighborhoods. We use camera inspection to locate root intrusion, offset joints, and collapsed sections, then repair or replace the affected line with minimal excavation.
Commercial Plumbing Services in Annandale VA
Annandale's commercial corridor along Little River Turnpike and Columbia Pike includes restaurants, retail centers, medical offices, and mixed-use developments. The Professor Plumbers provides Class A licensed commercial plumbing service to keep Annandale businesses operating without interruption.
Commercial Drain & Sewer Service
Restaurant grease, retail restroom backups, and office building drain failures require commercial-grade hydro-jetting and camera inspection. We service commercial drain systems throughout Annandale's business corridor with minimal disruption to your operations.
Grease Trap Service
Annandale's dense restaurant scene along Little River Turnpike means grease trap compliance is a constant operational requirement. We pump, clean, and repair commercial grease traps on a scheduled and emergency basis, keeping your kitchen in compliance with Fairfax County health codes.
Backflow Prevention
Fairfax Water requires annual backflow preventer testing and certification for commercial properties. We install, test, repair, and certify backflow prevention assemblies for Annandale businesses, and we file the required documentation with Fairfax Water on your behalf.
Commercial Water Heater Service
Commercial water heaters in Annandale restaurants, medical offices, and multi-unit buildings take a beating from Fairfax County's hard water. We service and replace commercial tank, tankless, and heat pump water heaters from all major manufacturers, with emergency response available 24/7.
Tenant Improvement Plumbing
Annandale's commercial real estate market sees frequent tenant turnover and buildout. We handle all plumbing rough-in and finish work for commercial tenant improvements, pulling Fairfax County commercial permits and coordinating with general contractors and building inspectors.
Commercial Emergency Response
A plumbing failure at your Annandale business means lost revenue and potential health code violations. The Professor Plumbers provides 24/7 commercial emergency plumbing response throughout Annandale and Fairfax County — call (571) 632-6151 for immediate dispatch.
Fairfax County Permits & Code Compliance in Annandale
All plumbing work in Annandale falls under Fairfax County's building permit and inspection requirements, enforced by the Fairfax County Department of Land Development Services. Water line replacements, sewer line repairs, water heater installations, and any work that opens walls or floors requires a Fairfax County plumbing permit — and that permit must be pulled by a licensed contractor, not a homeowner.
The Professor Plumbers holds a Virginia Class A Plumbing License and is fully authorized to pull Fairfax County plumbing permits. We handle the permit application, schedule the required inspections, and provide you with the final inspection sign-off for your records. Permitted work protects your home's resale value, keeps your homeowner's insurance valid, and ensures the work meets current Virginia Uniform Statewide Building Code standards.
Beware of unlicensed contractors offering to do plumbing work in Annandale without permits — it is illegal, it voids your homeowner's insurance on related claims, and it creates disclosure obligations when you sell your home. The Professor Plumbers does it right, every time.
Licensed. Permitted. No Shortcuts.
Every job in Annandale is done by our own Class A licensed technicians — never subcontractors.
