Signs Your Downpipes Need Repairing or Unblocking
A faulty downpipe channels rainwater directly against your brickwork instead of safely into the drain. If you notice any of the following signs, it’s time to call our experts before cosmetic damage becomes a structural problem:
Overflowing Gutters: Water spilling over the sides of your gutters during rainfall is a classic sign the downpipe is blocked.
Water Stains on Walls: Dark, damp patches or streaks running down your exterior walls below the gutter line.
Cracked or Broken Pipes: Visible cracks, splits, or disconnected sections in the downpipe.
Pooling Water: Water collecting at the base of your property near the downpipe outlet.
Gurgling Sounds: Noises from the pipe indicate trapped air and a partial blockage.
Interior Damp: Unexplained damp or mould appearing on internal walls can be caused by water penetration from a faulty downpipe.
Ignoring these warnings can lead to costly brickwork repairs, penetrating damp, and even foundation issues. Our emergency team is ready to help 24/7.
The Dangers of Neglecting Faulty Downpipes
A downpipe is a critical part of your property’s defence against the elements. When it fails, the consequences can be severe:
Penetrating Damp: Water running down walls seeps into the brickwork, causing internal damp, mould, and spoiled decoration.
Structural Damage: Constant saturation can erode mortar joints and damage the integrity of your brickwork over time.
Foundation Issues: Water pooling at the base of your property can saturate the ground, potentially leading to subsidence and foundation damage.
Landscape Erosion: Uncontrolled water flow can wash away soil and damage gardens or pathways.

Frequently Asked Questions
What does your downpipe repair service cost?
We offer competitive fixed-price rates for most downpipe repairs and unblocking jobs. We will always provide a full quote for you to approve before any work begins.
What causes downpipes to get blocked?
The most common causes are a build-up of leaves, moss, and twigs washed from the roof. Silt, debris, and sometimes even bird nests or tennis balls can also cause major blockages.
Can you repair old cast iron downpipes?
Yes. Where possible, we can repair cracks and joints on cast iron systems. If the corrosion is too severe, we can provide a no-obligation quote to replace a section or the entire pipe with a modern, durable equivalent.
How can I prevent my downpipes from getting blocked again?
Regular gutter cleaning is the best form of prevention. We also recommend installing gutter guards or leaf filters, which stop the bulk of debris from ever entering the downpipe.
What if the blockage is further down in the underground drain?
Our engineers are equipped to handle that too. If clearing the downpipe doesn’t solve the issue, we can use our CCTV drain cameras to inspect the underground gully and pipework and provide a quote for clearing that blockage as well.
