Overflowing Outside Drain? Here is What to Do (and What it Costs to Fix)

There are few things more unpleasant for a homeowner than stepping outside to find a gully overflowing with grey water and a distinctive smell. In Blackpool, Poulton, and across the Fylde Coast, our outside drains take a beating from heavy coastal rain and wind-blown debris.

If you are currently looking at a “lake” in your garden or driveway, you are probably asking two questions: “Can I fix this myself?” and “How much is this going to cost me?” At Drainage Experts, we believe in total transparency. Here is the local guide to outside blockages.

Common Causes of Outside Blockages

Unlike a kitchen sink, an outside drain is exposed to the elements. In the North West, we frequently see blockages caused by:

• Silt and Sand: Particularly common in South Shore and Lytham, where coastal sand enters the system.
• Leaves and Twigs: Autumn debris that bypasses the gully grate.
• Fat and Grease: “Fatbergs” that solidify as they hit the cold air in the outside pipes.

The Cost: Blocked Drain Outside House

We know that people searching for “blocked drain outside house cost” are often worried about being hit with a massive bill. When you call us, we keep it simple:

Can I Clear it Myself?

If you have a pair of heavy-duty gloves, you can try to reach into the gully and remove any visible leaves or sludge. However, if the water doesn’t drop immediately, the clog is further down the pipe. Pushing a stick or a rod into it blindly can often compact the blockage, making it harder (and more expensive) to clear later.

For more technical problems, like those caused by tree roots, we recommend a CCTV Drain Survey to see exactly what is happening underground. You can find more information about pipe maintenance on the United Utilities website.
