Frequently Asked Questions
Get answers to common questions about our drainage services
A persistent drain smell indoors often means a trapped blockage or dry trap. Try flushing all plugholes and pouring water into seldom-used drains. If the smell remains, it’s wise to book a professional inspection to find and clear the source.
Responsibility for shared drains, lateral drains and public sewers usually rests with your local water company, not the homeowner, once pipes leave your property boundary. Private sections within your property remain your responsibility.
Tenants are normally responsible only for minor blockages caused by misuse. Landlords must address structural problems or blockages in main drains and arrange timely repairs to keep the system in working order.
Avoid tipping fats, oils, or food waste down sinks, and never flush wipes or sanitary items. Regularly clear hair from shower traps and watch for tree roots near outside drains if you have a garden.
Drain lining can often repair cracked or leaking pipes without excavation, saving disruption and time. If pipes have collapsed or severe damage, excavation and replacement may be necessary instead.
A pre-purchase drain survey uses a CCTV camera to inspect the underground pipes for cracks, blockages or roots. You’ll receive a detailed report and footage to help you avoid costly surprises after you move in.
