SIX7 PLUMBING
SIX7 Plumbing Sewer Repair Colombo
We trace the line before we dig a centimetre. Guess-excavation digs three holes to find one break; we open one targeted trench and replace the failed section with proper bedding.
Sewage travels — the smell and the break are rarely the same hole. Ground movement collapses aged mains at the joints first, roots invade through cracks, vehicle load on old clay crushes buried runs, and the surface sinkhole appears metres from the actual failure. Tracing before digging is the difference between a one-day repair and a week of trenches. We map the run, open the smallest trench that does the job, and replace with new pipe bedded and backfilled to spec.
Borupana is converting from per-property septic pits to a unified sewer main, and we have conversion requests lined up as houses connect. If your property sits in a conversion zone, the connection involves new junctions to the main — not adapted old pipe — and we quote that work before you commit. Re-tiling and landscaping over the trench are separate quoted lines, so the invoice doesn't surprise you with "while we're here" work.

How We Repair It
Our repair process ensures your sewer line is fixed or replaced correctly, the first time.
Camera Survey
We camera-survey the line to find the exact fault — no guessing, no unnecessary digging.
Repair or Replace
Cracked or misaligned: we repair. Collapsed or root-infested: we replace.
Slope & Flow Test
Correct slope and flow confirmed before we call it done.
Neighbor Approved
"We prove the fault on camera first — the repair plan follows the footage, not the other way round."

"You get the findings in plain language — what collapsed, why it failed, and what each fix option costs."

Fitted to Last
We use proper pipe materials, correct slope, and verified flow for every repair.
Camera Survey
CCTV inspection finds the exact fault before any digging begins.
Proper Materials
Right pipe material for your soil and pressure — PVC, HDPE, or concrete.
Slope Verified
Correct gradient confirmed — no future backups from bad slope.
The Nitty Gritty
Cracks, collapses, and bad slope cause backups. Here's what we do:
- Camera Survey: CCTV inspection finds the exact fault before any digging.
- Repair or Replace: We fix what can be fixed and replace what can't.
- Slope & Flow Test: Correct gradient and flow confirmed before sign-off.
ALL REPAIRS INCLUDE
6-Month Workmanship Warranty
"Sewer problems always mean full replacement."
Many faults can be repaired without full replacement. Camera survey tells us which.
A camera log before excavation turns a disputed repair into a documented one — depth, run length and fracture in the same recording.
If multiple drains back up at once, it's usually the main line — not individual pipes. Get a camera survey first.
