Stop Rats Entering Your Home Through the Drains
If you are hearing scratching noises in your walls, seeing droppings, or have a recurring rat problem that pest control cannot solve, the issue is almost certainly your drains.
Research indicates that over 50% of rat infestations in the UK originate from defects in the drainage system. Rats are excellent swimmers; they can tread water for days and hold their breath for up to three minutes, allowing them to swim up through toilet U-bends. However, they usually enter through “Breach Points”—cracks or displaced joints in the pipework under your house.
Why Poison is Not the Solution
Many homeowners immediately call a pest controller to lay poison. While this kills the rats currently in your house, it does not close the front door.
As long as the defect in your drain remains open, the “scent trails” left by previous rats will invite new rodents into your home within weeks. To solve the problem permanently, you must repair the structural defect.
Warning Signs of Rats in Drains
Noises: Scratching or scuttling sounds in wall cavities or ceilings, typically at night.
Smells: A stale, ammonia-like smell (rat urine) or the smell of a decaying animal in a void.
Subsidence: Small holes or dips appearing in your garden or driveway (where rats are burrowing out of the pipe).

Drain 247 delivers a permanent solution to stop rats at the source.
Step 1: The CCTV Survey We use specialist CCTV cameras to inspect your sub-surface pipework. We identify entry points such as gnaw marks, displaced joints, or open redundant pipes where rats are squeezing through.
Step 2: Structural Repair (No-Dig Technology) We repair the breach without digging up your floors using Structural Patch Lining. We inflate a resin sleeve inside the drain, creating a rock-hard “pipe within a pipe” that seals the hole and is impossible for rats to chew through.
Step 3: Rat Flap Installation Finally, we install a stainless steel Non-Return Valve (Rat Flap). This device lets wastewater flow out but locks shut against incoming rats, creating an impenetrable physical barrier.
Frequently Asked Questions
Can rats really swim up my toilet?
Yes. Rats are excellent swimmers and can hold their breath for up to 3 minutes. The U-bend in your toilet is no obstacle for them. Installing a rat flap prevents this.
How do I know if the rats are coming from the drains or the roof?
Rats from drains tend to leave damp patches, bad smells, or scratching noises near ground-floor pipes. Rats in the roof usually enter via gutters. A CCTV survey is the only way to be 100% sure
Do you kill the rats??
Our job is to stop them entering. Once we patch the drain and install a blocker, the rats can leave the sewer but cannot get back into your house. They will move on to find an easier food source.
Do you offer emergency response for rats?
Yes. We understand how distressing it is to have rats in your home. We treat active rodent infestations as a priority and aim for same-day attendance across Watford and London. We can conduct the survey and install a temporary or permanent block immediately to secure your property.
