How to Hire a Plumber
Plumbing work inside walls and under slabs can cause serious structural damage if done wrong. The right credentials and a written scope protect you before the first pipe is touched.
Confirm state plumbing licence
Plumbing is licensed at the state level and requirements vary. Always ask for the licence number and verify it independently through your state's contractor licensing board before work begins.
Check for master plumber status
A master plumber has passed advanced exams and carries greater liability. For major work — repiping, sewer replacement, water heater installs — always request a master plumber or a journeyman supervised by one.
Ask about permit requirements
Most jurisdictions require permits for water heater replacements, repiping, and sewer work. A plumber who skips permits is leaving you exposed — unpermitted plumbing can void your homeowner's insurance and block a future home sale.
Get a written scope before any diagnosis fee
Some plumbers charge a diagnosis or dispatch fee. Confirm upfront whether that fee is waived if you proceed with the repair, and get the scope of work in writing before authorizing anything.
Request itemised quotes
A quote should break out labor, materials, permit fees, and disposal separately. Lump-sum quotes make it impossible to compare bids or identify inflated line items.
Verify insurance coverage
Plumbing work inside walls and under slabs carries real damage risk. Confirm the contractor carries both general liability and workers' compensation — and ask for a certificate of insurance, not just their word.
Red Flags to Watch For
Plumbing emergencies create urgency — and unscrupulous contractors exploit that. These warning signs should stop any negotiation immediately.
- Quotes a price over the phone without inspecting the problem
- Refuses to provide a written quote before starting work
- Recommends full pipe replacement without a camera inspection
- Charges a flat "emergency" rate with no itemised breakdown
- No state plumbing licence or cannot provide licence number
- Requests full payment before work begins
- Pressure to sign a maintenance contract before completing the repair
- No physical business address or local references
Seasonal Maintenance Checklist
Most plumbing emergencies are preventable. These quarterly checks take under 30 minutes and can save thousands in water damage and emergency call-out fees.
Spring
- Inspect under sinks and around toilets for slow leaks or water stains
- Test the pressure relief valve on your water heater — it should release and reseat cleanly
- Check outdoor hose bibs for freeze damage from winter
- Clear slow drains with a drain snake before they become full blockages
Summer
- Monitor water bills for unexplained spikes — a hidden leak can waste thousands of gallons
- Check irrigation system connections and backflow preventers
- Inspect washing machine hoses for bulging, cracking, or corrosion
Autumn
- Disconnect and drain outdoor hoses before the first freeze
- Insulate exposed pipes in unheated spaces — crawl spaces, garages, exterior walls
- Flush your water heater to remove sediment build-up that reduces efficiency
- Locate your main water shut-off valve and confirm it operates freely
Winter
- Keep cabinet doors under sinks open on cold nights to allow warm air to reach pipes
- Let a trickle of water run from faucets on exterior walls during hard freezes
- Know where your main shut-off is — a burst pipe requires immediate action
- Check for frost on exposed pipes in unheated areas after overnight freezes
