Why Are Rodents in My Drains?

Finding rats in your drains is stressful. They’re drawn by food smells, waste lines, and any structural weakness in your drainage network. Even small cracks in your drain, displaced joints or gaps can allow rodents to enter the system. Their climbing ability enables them to navigate through sewer tunnels and up into domestic drains.

If you want lasting peace of mind that rats cannot enter your property, BN Drainage will install rat gates inside the drains to seal off rodent access.

Gates for sewer rats

During a CCTV drain survey, we can detect rodent activity and identify access routes within your drains. Once we confirm where rats are travelling, our team fits rat gates appropriately in the drain runs or junctions, thereby preventing any new rodents from entering the system.

Rat Gates for Drain Protection

If rodents have already been cleared from your drains you will still need protection. Our rat gates (designed for drains, not drainpipes) allow wastewater to flow out while blocking rats from coming back in. They’re a simple, passive barrier that works quietly and effectively — safeguarding your property from future infestations.

Contact Us for a Lasting Solution

If you want to experience the peace of mind that comes with having our rat gates installed, make sure to get in touch. You can count on our rat gates to prevent any rodents finding a way into your property via the drains. Give us a call on 0800 999 1769 or 0203 337 0349 or email info@bndrainageltd.com and we’ll get back to you to discuss your requirements.

FAQs About Rodent Prevention & Rat Gate Installation

How can I tell if my drains are at risk of a rodent problem?

If your property is near open land, food establishments, or older drainage systems, there’s a higher chance that rats may use the sewers to reach your home. Regular drain maintenance and a professional inspection can reveal early signs of damage or entry routes before rodents get in.

Do I need both pest control and drainage specialists to deal with rats?

Not necessarily. BN Drainage offers both rodent control and drain expertise, meaning you won’t need two separate companies. We can remove existing rodents and address the root cause in the drains, ensuring the issue doesn’t come back.

Will installing a rat gate affect my drainage performance?

No, rat gates are designed to allow full wastewater flow while blocking rodents. They don’t restrict or slow down drainage when correctly fitted by professionals. You’ll notice no change in your plumbing performance after installation.

How long do rat gates last once installed?

When properly maintained, rat gates can last for many years. They’re made from durable stainless steel that resists rust, corrosion, and damage from rodents or debris. We recommend having your drains checked every couple of years to make sure the gate remains clear and secure.

Can rats chew through a rat gate?

No. Rat gates are made of stainless steel — far tougher than plastic or rubber fittings. Rats cannot gnaw through them, making them one of the most reliable long-term rodent prevention measures available.

Can I maintain or clean a rat gate myself?

It’s best left to professionals. While rat gates require very little maintenance, an annual drain inspection ensures they remain free of blockages and securely fitted. Attempting to access drains without proper tools can be unsafe and may damage the gate.

Will installing rat gates help prevent other problems, too?

Yes. By sealing vulnerable points in your drainage system, rat gates can also reduce the risk of foul odours, water backflow, and other pests using the same routes. They contribute to better overall drainage hygiene and property protection.

How quickly can BN Drainage respond to a rodent prevention enquiry?

We offer a prompt response across London and the surrounding areas. In most cases, we can arrange a site visit or CCTV survey within 24–48 hours to assess the issue and recommend the right solution.

 Trustindex verifies that the original source of the review is Google. Barry from BN Drainage was very polite and professional he went the extra mile to ensure that the job could be finished the same day and left the area clean and tidy . .The manhole that needed to be accessed to cap of the drain is on our neighbours driveway  and Barry was able to reassure them and me about the process . I would have no hesitation in recommending BN Drainage .

 Trustindex verifies that the original source of the review is Google. I would highly recommend BN Drainage. I called them out to fix a blocked drain, and they arrived within the hour. They quickly identified and fixed the problem, providing a fast, efficient and professional service.

They also sent over a job sheet detailing the work they had carried out, which was really helpful and kept me fully informed throughout.

Their prices were reasonable, and they were friendly and approachable from start to finish.

Overall, a great experience with a reliable company that I wouldn’t hesitate to use again. Highly recommended!

 Trustindex verifies that the original source of the review is Google. We'd had a blocked manhole and a toilet that wouldn't clear properly for about two weeks, so I was glad to get someone out. A contractor from BN Drainage attended, explained clearly what the problem was, and got stuck in straight away.

He was friendly, straightforward and didn't oversell anything. The engineer came out in the morning to finish the job. All sorted.

Dan and Barry explained the findings clearly over several phone calls and kindly reviewed repairs carried out by another contractor following their survey. Great communication and support throughout a stressful house purchase. Highly recommend!

 Trustindex verifies that the original source of the review is Google. This is a bona fide feed back review about BN Drainage Ltd, written with integrity and honesty. We recently discovered the horror of broken gulley drains and leaking water into our basements (i.e. our neighbour and ourselves because the gulley grains were connected) and were introduced to this drain specialist by our local Whatsapp group. From the beginning to the end of the job they have been an excellent company. Courteous and respectful (for us an important part of the relationship with any company); They inspected the drains and we received a detailed breakdown & invoice of the work that had to be done. The cost was very reasonable and much cheaper than we anticipated. It was a big job because our neighbour's drain being connected to ours, meant that they had to do the 2 jobs together. They set a date for the repairs and came on time as planned. We were expecting a big messy job with mud everywhere, but they were respectful of our house and living space and curtailed the mess and mud and cleared away the old drains and debris and left the site clean ready for us to do our home cleaning-up. They removed the old drains, pipes & debris etc from our house altogether. We anticipated that our conservatory tiles would have to be broken during the work (and replicas hard to find since they had been down for many ears), but the engineers found they did not have to do this and preserved our tiles. We received an excellent professionally produced report about their findings (before and after the job) and details of the work they had carried out. They really do deserve a big 'thank you' for a job well done, for a very good cost and deserve a 5 star rating.
