Many plumbing tasks can be completed yourself, but there will come a time when your knowledge and equipment fails you. You can cause serious damage to your home if you step beyond your capabilities with plumbing, so sometimes a professional is needed.

Here are the top 5 things to consider when hiring a plumber.

Licensing

You need to ensure that the plumber is licensed to carry out the work that you need of them. A plumber that is not licensed to work with gas heaters will be useless if this is what needs fixing and they will charge you a call out fee either way.

Insurance

Your plumber needs to be insured in the case of a mishap. This is important to protect your home and also to protect yourself in case they are injured on the premises.

Accurate quotes

A good plumber should be able to give you an accurate appraisal of the situation and an accurate quote for the work.

Experience

The more experienced the plumber the better they should be. Try to avoid hiring someone fresh out of training because they may not know what to do if something goes wrong.

Warranty

The best plumbers will also give you a guarantee on the longevity of the work that they complete for you. This will give you peace of mind that the work has been properly completed.
