Poor stormwater drainage can cause flooding, structural damage, and costly repairs. Mr. Clog designs, installs, and repairs stormwater drainage systems for homes and businesses across Sydney. From clearing blocked pits to full drainage redesigns, we keep water moving away from your property.

How It Works

01

We inspect your property's drainage — pits, pipes, and surface flow — to identify where water is pooling or not flowing correctly.

02

We identify the root cause — blockage, incorrect fall, undersized pipe, or failed pit — and quote the fix.

03

We clear blockages, repair damaged pits, or install new drainage infrastructure as required.

04

We test the system under simulated flow conditions and confirm all water is draining correctly.

Usually either a blocked stormwater pit or pipe, incorrect surface fall, or a drainage system that was never properly installed. We'll identify the cause quickly.
