Questions to Ask Before Hiring a Plumber

When hiring anyone to do work around your house, it’s hard to know what questions to ask to ensure that the tradesperson you select for your job is a qualified one. Plumbers are no exception, so we have prepared a list of questions to ask any plumber before giving them the go-ahead to start work in your home.

Written Estimates

The cost of any work to be done should be laid out, clearly and in writing, before any work starts. Back of the envelope calculations and fat thumb estimates are not reliable, and arguing about charges on the bill will be a lot more awkward after the job is done. Make sure your written estimate also includes materials.

Guaranteed Work

Quality service providers stand behind their work. They offer free, no-obligation quotes and warranties that cover their work. If the plumber you have contacted about a job in your house doesn’t offer a warranty for their work, well, let’s just say it should be hard to trust a company that doesn’t trust itself.


In most cases, subcontractors are fine, as long as the company you hired is prepared to offer the same guarantees on the subcontracted work that they do for their own. After all, a company’s reputation is the best marketing tool in their toolbox, so they shouldn’t be willing to risk it on a sub-par subcontractor.

Positive References

Reputable plumbers have contact information for past clients who are pleased to recommend their services. If you ask for references and the answer is anything but “Absolutely, here you go!” you have cause to be wary.

Specific Knowledge of Your Area of Concern

A good plumber might specialize in a particular plumbing problem, but should be knowledgeable about all aspects of emergency plumbing repairs. A local plumber will know about issues that are common to your area, like low water pressure or particularly gnarly tree roots. Make sure the plumber you hire knows your area and thoroughly understands your problem.

A little extra time spent asking a plumber the right questions can save you time and money, and make sure you get the job done right the first time.
