CONSTRUCTION AND DRAINAGE

Get your earthworks done right first time with Sao Contractors who offer a full range of services

 Sao Contractors is a certified drainlaying company based in Wellington that lays new drains and water pipes for both commercial clients and homeowners alongside a range of earthwork services and traffic management options.  


As drainage contractors, we can lay and repair all the drainage and water pipes under and around your home, or commercial premises, but not within it. Most of the drainage work undertaken requires council consent. The majority of our clients already have consent before coming to us. However, if you don’t our Civil Construction Contractors can go through the process with you.  


Sao Contractors is an honest and reliable contractor committed to delivering workmanship of a consistently high standard. Whether you have a drain that needs unblocking, or require a comprehensive drainage solution that involves excavating and concreting, please contact us today to arrange a site visit.
