As the leading drainage experts in Sussex, we've seen it all when it comes to blocked drains. From simple clogs to more complex issues, we've helped countless homeowners across Shoreham, Haywards Heath, Brighton, and beyond get their drains flowing smoothly again. In this blog, we'll be sharing the top 5 reasons your drains keep getting blocked, and what you can do to prevent it from happening again.

  1. Foreign Objects in Your Drain

One of the most common causes of blocked drains is foreign objects. This can include anything from hair and food scraps to baby wipes and hygiene products. These items can get stuck in your drain and cause a blockage, preventing water from flowing freely. The best way to prevent this is to avoid putting anything down your drain that doesn't belong there. We recommend using a drain guard or filter to catch any small items that might slip through!

  1. Grease and Fat Build-up

Grease and fat are other common causes of blocked drains. When you pour grease or fat down your drain after cooking, it solidifies and sticks to the walls of your pipes. Over time, this build-up can cause a blockage that prevents water from flowing through. To prevent this, avoid pouring grease and fat down your drain. Instead, let it cool and solidify, then dispose of it in the trash.

  1. Tree Roots

Tree roots can be a major problem for drains in Sussex. As trees grow, their roots can penetrate your pipes and cause blockages. If you have trees near your property, it's important to have your pipes checked regularly to ensure there are no roots causing damage. If roots are found, a drain survey and a professional repair service may be required.

  1. Structural Damage

Over time, drains can become damaged due to age or wear and tear. This can cause cracks, leaks, and other structural problems that can lead to blockages. If you notice any signs of damage, such as damp patches, slow-draining water, or foul smells, it's important to have your drains inspected by a professional. In some cases, a repair or replacement may be necessary.

  1. Poor Drainage System Design

In some cases, the drainage system in a property may not be designed correctly, which can lead to blockages. This could include issues such as incorrect pipe sizing, poor gradients, or a lack of ventilation. If you're experiencing persistent drainage problems, it may be worth having your system checked by a professional to see if any design issues need to be addressed.


Blocked drains are a common problem in Sussex, but they can be prevented with the right care and maintenance. By avoiding foreign objects in your drain, disposing of grease and fat correctly, checking for tree root damage, repairing structural damage, and addressing any design issues, you can keep your drains flowing smoothly for years to come.
