Common Causes of Blocked Drains 

Common Causes of Blocked Drains In Southampton​


Blocked drains in Southampton are often caused by everyday waste such as hair, soap scum, and food particles, but more severe blockages can occur due to root intrusion, broken pipes, and a build up of fats, oils, and grease. Older properties in the Southampton area may also suffer from structural issues in their drainage systems, making them more prone to blockages. Our experienced drain unblocking team at GSB Drainage understands the specific drainage challenges that Southampton properties face, and we use the latest technology to identify and resolve these issues quickly and efficiently.​

Types of Drain Unblocking Services in Southampton


​At GSB Drainage, we use a variety of effective methods to clear blocked drains and restore smooth flow. Our techniques are tailored to the cause and severity of the blockage, ensuring fast and efficient results. Here are some of the main methods we use:

  • High Pressure Water Jetting
    This powerful method uses a high pressure water jet to break down and flush away blockages. Ideal for stubborn obstructions, water jetting is both eco friendly and highly effective, clearing even the toughest build ups quickly.

  • Drain Rods
    For blockages that are closer to the drain entrance, drain rods offer a straightforward solution. These flexible rods are ideal for dislodging smaller clogs and pushing through obstructions like leaves, paper, and other materials that may be causing the blockage.

  • Mechanical Augers and Snakes
    Mechanical augers, also known as drain snakes, are particularly useful for more challenging clogs. This technique involves inserting a rotating auger that breaks down materials and clears the way. It's highly effective for blockages caused by grease, roots, or other hard to remove debris.

Frequently Asked Questions – Blocked Drains in Southampton


How quickly can I get help for a blocked drain in Southampton?

We offer 24/7 emergency drain unblocking in Southampton, so you can get help any time of day or night. Our local team will arrive quickly to fix your blocked drain and prevent further damage. We know drainage issues can’t wait, and we strive to resolve your problem as fast as possible.

 

What are the common causes of blocked drains in Southampton?
Blocked drains in Southampton are usually caused by a buildup of everyday materials and debris. Common culprits include grease, fat, and oil down kitchen sinks, flushing wet wipes or sanitary items, invasive tree roots, and scale buildup in older pipes. Even heavy rainfall can overload outdoor drains or sewers, contributing to blockages during storms.

 

What are the signs of a blocked drain?
Typical warning signs of a blocked drain include slow-draining sinks or bathtubs, unpleasant odors from drains, and gurgling noises in the pipes. You might also notice water rising in the toilet or backing up into sinks, or even standing water near outdoor drains. If you spot any of these signs in your property, it’s likely you have a blockage that needs attention.

 

Can I unblock a drain myself, or should I call a professional?
You can attempt to clear minor clogs yourself using a plunger or a baking soda and vinegar solution. However, many blocked drains – especially stubborn or recurring ones – require professional equipment and expertise to clear safely. If DIY methods don’t work or the blockage keeps coming back, it’s best to call a drainage specialist to ensure the drain is fully cleared without damaging your pipes.

 

Should I call a plumber or a drain specialist for a blocked drain?
For a simple clogged sink or minor plumbing issue, a general plumber might be able to help. But for serious or persistent blocked drains in Southampton, a dedicated drain specialist (like GSB Drainage) is recommended. We have specialist tools such as high-pressure jetting units and CCTV cameras specifically for drain unblocking, ensuring a thorough fix and long-term solution for your drainage problem.

 

How much does it cost to unblock a drain in Southampton?
The cost can vary depending on the severity and location of the blockage, but we offer very competitive and transparent pricing. We provide fair, upfront rates with no hidden fees, and no call-out charge. For an exact quote, we’re happy to assess your situation and give a free estimate so you know what to expect before any work begins.

 

Do you charge a call-out fee for drain unblocking in Southampton?
No – we do not charge any call-out fee for coming out to blocked drains in the Southampton area. You only pay for the work needed to clear or repair your drain. Our pricing is honest and transparent, so you won’t encounter surprise charges for simply having us attend your property.

 

Which areas of Southampton do you cover?
We cover all areas in and around Southampton. Our team is based locally in Sholing and regularly serves the entire Southampton city area, including Bitterne, Woolston, Hedge End, Eastleigh, Netley and other nearby locations. If you’re in the Southampton region or surrounding towns, we can reach you quickly to help with your blocked drain.

 

Do you provide drain services for businesses as well as homes in Southampton?
Yes. We handle blocked drains for both residential and commercial clients across Southampton. Our customers include homeowners, landlords, letting agents, restaurants, shops, offices and other local businesses. Whether it’s a simple home drain blockage or a larger-scale issue at commercial premises, our team has the expertise and equipment to resolve it.

 

Can you unblock indoor drains like toilets and sinks, or only outside drains?
We unblock all types of drains, both indoors and outdoors. This includes clogged toilets, sinks, showers, and bath drains inside your property, as well as external drains, gullies, manholes, and sewer lines on your property. No matter where the blockage is, our Southampton drain engineers can clear it and get your plumbing flowing properly again.

 

Will you need to dig up my property to fix a blocked drain?
In most cases, no. We use modern, non-invasive methods to clear blocked drains, such as high-pressure water jetting and drain rodding, which usually remove the blockage without any excavation. We also have CCTV drain survey cameras to pinpoint issues underground. Even if a pipe is damaged, we offer trenchless repair techniques (like drain relining) to fix the problem with minimal or no digging on your property.

 

Are blocked drains a health hazard?
Yes – if left untreated, a blocked drain can pose health and hygiene risks. Standing water and sewage from a blockage can breed bacteria and attract pests, leading to unpleasant odors and potential health issues. Additionally, overflowing or backed-up drains can cause water damage and unsanitary conditions in your home or business. It’s best to address blockages promptly to keep your property safe and hygienic.

 

Who is responsible for fixing a blocked drain in Southampton – the homeowner or the water company?
Generally, as a homeowner you are responsible for drains within the boundaries of your property. If the blocked drain is part of your home’s private drainage (up to your property boundary), it’s up to you (or your landlord, for rented properties) to arrange clearing it. The water company (Southern Water in Southampton) is responsible for public sewers and lateral drains outside your property line. If you suspect the blockage is in a public sewer, you can contact the water company; otherwise, a private drainage expert can help with your home’s drains.

 

How often should I have my drains cleaned to prevent blockages?

It’s a good idea to have your drains professionally cleaned on a routine basis to avoid future blockages. For an average home in Southampton, we recommend a preventative drain cleaning every 18–24 months. Regular maintenance (about once every year or two) helps clear out fat, scale, and other buildup before it causes a blockage. If your property has older pipes or you’ve had frequent issues, you might benefit from more frequent inspections or drain cleaning as a precaution.
