Cotswold Drainage cleared a blocked drainage pipe from our septic tank. Not the easiest access and a combination of pipe and soakaway to investigate. Adrian was excellent - prompt, friendly and willing to go the extra yard when things were looking difficult. Very pleased with the service.
- Geoff Smith

- Donald Gilder
From start to finish Nikki and the team were brilliant . Quotes through quickly and house buying drainage survey results through in a couple days. Would highly recommend this company. Thank you all.
- Carrie Crinage
Professional and reliable with first class service, definitely recommend. We had an issue with an ACO drain in the recent torrential storms which caused flooding in our integral garage. Having been flooded in two previous properties before this occasion and now being paranoid about water, we wanted to rectify the situation quickly to mitigate any future problems. We searched the Internet looking for a professional, trustworthy company who we could rely upon to fix the issue quickly and provide us with peace of mind. We found and researched Cotswold Drainage, particularly taking into account the customer feedback and first class reviews in our decision. We couldn't be more delighted from our initial contact with Nikki, two site visits one by Dave to review the issue quickly followed up by Adrian for a camera inspection, to Keith who carried out the work over 3 days in the most awful of weather (rain, drizzle and bitterly cold). Keith worked flat out every day at the same time always professional, cheerful and courteous. We cannot fault them and and would highly recommend them.

    What causes emergency blockages?

    Blocked drains can become emergencies when your indoor or outside drains are beginning to overflow. These blockages are commonly caused by just a few key issues.

    The most common cause is the build up of foreign objects such as sanitary products, wipes, and nappies. These items do not break down easily and can quickly create a blockage. Fat, oil, and grease (FOG) are similar, solidifying inside your drains, leading to severe blockages.

    Tree roots can also infiltrate your drainage system, growing and expanding until they block the flow of water.

    Collapsed pipes can also occur due to aging drain systems or ground movement. These will often require immediate professional drain repairs to prevent extensive damage.

    Drain unblocking process

    Once resolved, it is easy to avoid future blocked drain emergencies with some sensible steps and regular maintenance.

    Our number one recommendation is to avoid flushing foreign objects or FOG down the drain. These are the most common cause of blockages and so many could be avoid by just being mindful about what goes down your drains. 

    Installing drain screens and hair catchers can help reduce any build ups inside your drains, however even hard water can cause slow build ups over time.

    We recommend regular drain cleaning and drain inspections to stop issues before they become emergencies. Talk to our team about our routine checks for that extra peace of mind.

    Drain unblocking process

    Free CCTV survey for peace of mind

    After attending an emergency blockage we carry out a CCTV drain survey on the effected run. If this shows the run is clear and in a good state of repair and with no further works required, we guarantee this section of the pipework from being blocked for the next 6 months. Giving our customers peace of mind!

    Frequently Asked Emergency Drain Unblocking Questions

    Is a blocked drain an emergency?

    Blocked drains can become an emergency very quickly and can cause serious issues, such as flooding, property damage, bad odours and environmental damage. Minor blockages can usually be unblocked quite easily; however, certain factors over time can cause serious blockages which means you should contact us here at Cotswold Drainage immediately.

    Who do I call for an outside blocked drain?

    For blocked drains outside it’s always recommended to contact a drainage professional as attempting to clear it yourself without the correct knowledge poses health risks and could lead to further damage.

    Outside drains can be blocked by several things, such as plant life, leaves and twigs, dirt, and disturbed soil. If you suspect that your outdoor drain system has been affected by these elements, contact Cotswold

    Drainage – we will happily unblock your outside drains with our specialist equipment, including our high-powered drain jetting system.

    Can I unblock a drain myself?

    While some small and minor blockages can be cleared by property owners, you should always hire professionals to use their expert knowledge and equipment to safely solve all types of drainage problems to alleviate the risk of further damage in the future.

    Our drain unblocking services come with a full, six-month warranty giving you peace of mind and we can survey your property using sophisticated CCTV technology, free of charge.

    What happens if you leave a blocked drain?

    If you leave a blocked drain for even just a short time, you will run the risk of bad odours, flooding, environmental hazards and more problems that will cost you extensive repairs and services long term. The last thing you’ll want is to be left in an emergency, panicking about what to do when you have water flowing into your property or a foul smell infiltrating your office building.
