Key information

When you need a waterproofing licence

You must have a licence before you do any residential building work in NSW, including waterproofing, that is valued at more than $5000 in labour and materials (incl GST).

What is waterproofing?

Waterproofing is any protective treatment of a home to prevent water or moisture getting into it.

It is also the protective treatment of wet areas of a home (such as a shower) to stop the unwanted escape of water from those areas.

The protective treatment used is solid membranes or membranes applied by brush, roller or any other method.

To learn more about what is considered waterproofing work, see the definition in schedule 4 of the Home Building Regulation 2014.

Licence types

Waterproofing is trade work.

There are different types of licences available in NSW depending on whether you want to contract for another party, supervise work, do the work, or a combination of these roles.

Contractor licence

A contractor licence allows you to contract and advertise to do work. You can only do the types of work described on your licence card. Contractor licences can be issued to individuals and to companies and partnerships.

You can apply for a 1, 3 or 5 year licence.

Qualified supervisor certificate

A qualified supervisor certificate allows you to supervise and do the work described on your certificate. Qualified supervisor certificates are only issued to individuals. A qualified supervisor certificate does not allow you to contract for work.

You can apply to have a qualified supervisor certificate issued for 1, 3 or 5 years.

Endorsed contractor licence

An endorsed contractor licence is issued to individuals who apply for a contractor licence and who also have the qualifications and experience needed to be a qualified supervisor. Endorsed contractor licence cards have ‘contractor licence (Q)’ printed on them to show they are also equivalent to a qualified supervisor certificate.
