Common questions

What if the plumber will not give a license number?

That is a reason to call someone else. Licensed contractors expect to be asked.

Is it rude to ask for pricing before they arrive?

No. Asking how the visit is priced is normal. A firm repair price is a different matter, since no one has seen the line yet.

Does this checklist apply to Fullerton Drain Cleaning too?

Yes. Use it with any plumber, including us. This is a preview site: our phone number is a temporary placeholder and the request form is not connected yet.
