Question 1

Should plumbers be certified or licensed?

Accepted Answer

Yes, most states require plumbers to be licensed, and for good reason. Licensed plumbers can provide written guarantees that hold legal weight.

As you browse our pro listings, take note of the "Angi Approved" badge. Angi Approved businesses meet our standards which include: background checks, required licenses, 3.0+ star ratings, advertising participation, and meeting eligibility criteria. Keep in mind licensing is different from certifications.

Question 2

What questions should I ask a plumbing contractor?

Accepted Answer

A quick pre-hire checklist for your plumbing contractor should include questions like:

Licensed for gas/water lines?Free site assessment?Transparent pricing policy?Experience with my fixture/brand?What if access causes damage?Priority emergency slots?Surface protection and cleanup?Warranty scope?

Aligning on these details promotes accountability from both sides.

Question 3

Should I clean before the plumber comes?

Accepted Answer

Before your plumber pays you a visit, it's a good idea to clean up any boxes, garbage, or other obstacles that could be in their way. Cleaning the area protects both the plumber and your household.

Pets should not be allowed near wet or open pipes.

Question 4

How much are typical plumbing repair costs?

Question 6

How long do plumbers take to complete a plumbing job?

Accepted Answer

Most simple, residential plumbing jobs and repairs can be completed within a few hours. Common short tasks include unstopping toilets, replacing wax rings, and installing faucet sets. Structural constraints—tile, stone, or concrete—often add demolition and patching time to the schedule. Confirm cleanup and haul-away expectations to save time.

Question 7

When should I call a plumber instead of DIY-ing my project?

Accepted Answer

If your DIY plumbing project isn't going according to plan, it may be time to bring in a professional.

Professional help is advised for:

Rapidly worsening leak rate
Stains spreading across ceilings
Thermal imaging or cameras needed
Replacement of multiple fittings
Boilers, heaters, or steam involved

There's nothing wrong with admitting you need a little extra help. If your project is more complicated than you thought, consider hiring a professional.
