What is a CCTV and do I require it?
CCTV stands for Closed-Circuit Television, and in drainage, it refers to a camera inspection of your pipes. It allows us to see exactly what’s happening inside your drains—identifying blockages, cracks, tree roots, or collapsed sections. You may require it if your drains are repeatedly blocking, you’re buying a property, or we need to investigate a more complex issue.
If you are unable to successfully unblock my drain, what is the next step?
If initial methods don’t work, we’ll carry out a CCTV drain inspection to pinpoint the cause of the problem. From there, we can recommend a long-term fix—whether that’s targeted jetting, root cutting, pipe relining, or excavation and repair.
Do you offer an annual drain cleaning service?
Yes. We provide annual or scheduled drain cleaning services to prevent issues before they arise. This is particularly useful for commercial properties, rental homes, or sites with a history of blockages.
I have a bad smell coming from my drain but it doesn’t seem blocked?
Bad odours can result from trapped debris, dry traps, or damaged pipes. Even if there’s no visible blockage, we can investigate the cause—often using CCTV—and carry out a deep clean or repair to resolve the smell.
Can you conduct a pre-purchase house drain inspection?
Absolutely. A CCTV pre-purchase inspection gives you peace of mind before buying, by uncovering hidden drain issues like cracks, blockages, or tree root intrusion—potential problems that might otherwise be missed.
I have a blocked cesspit, what is the process?
We’ll start by removing any surface debris, then use high-pressure water jets to flush out the cesspit and surrounding stormwater lines. If necessary, we’ll carry out a CCTV inspection to check for further blockages or damage in the system.
Can you locate drains that we are building over?
Yes, we offer drain locating services. Using sonar and CCTV equipment, we can accurately map the position and depth of underground drains—helping you comply with council building regulations and avoid costly mistakes during construction.
Do you do after hour or emergency call outs?
Absolutely. We provide 24/7 emergency call-out services for urgent drainage issues. Whether it’s after hours, on weekends, or public holidays, we’re ready to help when you need us most.
Can you guarantee your work?
Yes, we stand behind our work. All our services are carried out to industry standards, and we offer guarantees on both workmanship and materials where applicable. If there’s an issue, we’ll make it right.
