About our blocked drain services service
A blocked drain can quickly transform from a minor inconvenience into a significant property risk if not addressed by specialists. At Design N Build, we provide comprehensive blocked drain services designed to restore full functionality to your plumbing system. From kitchen sinks and bathroom plumbing issues to main external sewer lines, we handle obstructions of all sizes. Our service is essential for both residential homeowners facing domestic overflows and commercial operators who must maintain strict hygiene and safety standards. We often encounter blockages caused by grease build-up, foreign objects, or structural failures such as root ingress. Our engineers use industry-standard diagnostic tools to identify the exact cause of the problem before applying the most effective solution. Whether it is part of a wider Drainage Solutions strategy or a standalone emergency, we ensure that your wastewater system meets all necessary building regulations and health standards. By integrating our drainage expertise with our broader plumbing catalogue, we provide a holistic approach to property maintenance that keeps your infrastructure running smoothly without the need for multiple contractors.

Effective removal of invasive tree roots that have entered the pipe joints and are causing structural damage or blockages.

Frequently asked questions
How much does it cost to clear a blocked drain?
The cost of clearing a blocked drain depends on the severity of the obstruction and the equipment required. A simple manual clearance is more affordable than high pressure water jetting or a full CCTV survey. We provide clear, fixed pricing for standard blockages and detailed quotes for more complex repair work.
How long will it take to unblock my drains?
In most cases, a standard blockage can be cleared within one to two hours. If the issue involves structural damage to the pipes or requires extensive root removal, the process may take longer. Our engineers aim to restore service on the first visit whenever possible.
When is a CCTV drainage survey necessary?
CCTV surveys use waterproof cameras to inspect the internal condition of your pipes. This is necessary when blockages recur frequently, as it allows us to identify hidden issues like pipe collapses, root ingress, or significant fat bergs without digging up your grounds.
Do you offer emergency call-outs for blocked drains?
Yes, we provide emergency plumbing support for drainage issues that pose an immediate risk to your property. While standard maintenance can be scheduled, we prioritise urgent cases where internal flooding or total loss of facilities has occurred.
Am I responsible for the blocked drain outside my house?
For residential properties, external drains on your land are typically your responsibility. Commercial tenants should check their lease agreements. In both cases, once the drain connects to the public sewer, the responsibility usually shifts to your local water authority.
Do you provide a warranty for drainage repairs?
We provide a guarantee on our labour and the effectiveness of the clearance at the time of the visit. For structural repairs like drain relining, we offer extended warranties that cover the integrity of the materials and the installation quality.
