Blocked Drains
Blocked drains cleared fast in Christchurch.
A blocked sewer drain is one of the most disruptive things a home can face, and left too long it means flooding and sewage you do not want near. If your drains are backing up or there are foul smells, get the blocked-drain experts out.

What's involved
A blocked drain is never convenient. Whether it is a slow sink, a gurgling toilet or a gully trap overflowing in the yard, we get out, find the cause and clear it properly rather than just poking it and hoping.
If the blockage keeps coming back, that usually means something underneath needs attention, a broken pipe, tree roots, or a collapsed section. We put a camera down to see exactly what is going on, then give you a straight answer and a fair price before any digging starts.

Blocked Drains questions.
Who do I call for a blocked drain in Christchurch?
Give Smart Contracting a call on 022 532 7278. We are Christchurch drainlayers, so we clear the blockage and, if there is a bigger problem underneath, we can fix that too, all with one crew.
Why does my drain keep blocking?
Repeat blockages usually mean tree roots, a broken or bellied pipe, or a collapsed section rather than a one-off. A quick camera inspection shows the real cause so you are not paying to clear the same drain twice.
Can you clear it and repair it in one visit?
Often yes. Because we are drainlayers, not just a clearing service, we can clear the line and carry out the repair, so you are not waiting on a second company.
