$0 call-out fee — any hour, any day · Available 24/7

Blocked drains in Alexandria are often not blockages at all. A great deal of the housing is converted industrial space, and waste lines retrofitted into buildings never designed for kitchens and bathrooms frequently have the wrong fall or the wrong bore. A drain that has always been slow is a different problem to one that has become slow.

The same job on camera: roots through a joint at 12.59 m. We locate the fault before we quote the fix.

Industrial buildings converted to residential often run waste through lines never intended for it. Insufficient fall or undersized pipe means the drain was never going to keep up, and clearing it changes nothing.

Mixed-use buildings put commercial kitchens on shared lines. Grease sets and narrows the pipe upstream of where it entered, producing blockages with no apparent cause.

Some lines here are old, oversized and made of materials no longer in use. A camera is the only reliable way to establish what is actually there before quoting work on it.

Fixed price quoted before we start. $0 call-out fee.

How It Works

01

Plunger or drain auger for a blockage near the fixture, the jet blaster for the main line.

02

For repeat blockages, a CCTV camera shows what is in the pipe and exactly where.

03

If the pipe is damaged, we explain relining or replacement, with a fixed price first.

04

We make sure the drain is flowing freely before we leave.

Common Questions

If it has always been slow rather than getting worse, it is usually fall or pipe size from the conversion. A camera confirms it and stops you paying to clear a line that is already clear.

Yes, including grease-related blockages in mixed-use buildings. Those generally need jetting rather than a drain machine to scour the pipe wall properly.

Yes. A pre-purchase CCTV inspection is worth doing on any converted building, and we provide footage and a written report.
