Why each step matters

The license lookup confirms you are dealing with a licensed contractor and that the name on the truck matches the license. A written pricing method before work starts avoids disagreement afterward. Testing the dishwasher and both basins before the plumber leaves catches a partial clear while help is still in your kitchen.

The invoice and any video become part of your home's plumbing history. The next plumber can see what was found, and you can tell whether a repeat clog is in the same place.

Common questions

What if the plumber cannot give a license number?

That is a good reason to keep looking. Licensed contractors expect to be asked.

Is a verbal price enough for a small clog?

A short written note or text with the price or pricing method is better. It protects both sides.

Should I stay in the kitchen while they work?

You do not need to watch every minute, but be available for questions and for the final test.
