Residential Drainage
Residential drainage for Christchurch homes.
We help Christchurch homeowners keep their drains clear, functional and problem-free. If sewage is backing up or water is not draining away, our team resolves it fast and protects your pipes from further damage.

What's involved
From a new gully trap to full drainage for a new build, Smart Contracting handles the lot for Christchurch homeowners and builders. Foul-water, stormwater, connections to the main, and the drainage that keeps water away from your foundations.
It is all done by certified drainlayers, to code, and signed off properly. We plan it so it works for your section, dig tidy, and leave the ground reinstated.
