The professionalism shown by Gary from our first meeting was refreshing. He had no doubt why my pond was not functioning properly. Within two days the quote arrived and was accepted. Within one week the job was complete. Exceptional service and highly recommended. It's only been a few months but the difference in the clarity of my pond is amazing.

A huge thank you to Garry for doing such a fantastic job cleaning our pond today. He worked incredibly hard all day in 35-degree heat and didn't stop until the job was done. Garry is extremely knowledgeable, professional, hardworking and respectful, and it was clear he really knows his stuff when it comes to ponds and their care. We're so pleased with the result that we'll now be using his services every month to keep the pond looking its best. Highly recommended.

Would definitely recommend to anyone who has a pond that's getting a bit beyond them. Good price, and clearly knows what he's doing. I'll be using Gary for the regular maintenance from now on.

Meet Gary

Hi, I'm Gary

Ponds have been my passion for 20 years. I clean them, maintain them and build them, and I still love the wildlife a healthy pond brings to a garden.

My standards are high. I treat every pond or lake as if it were my own, and I want you to get an exceptional service every time.

I'm also happy to share what I've learned along the way. I pass my knowledge on to every customer, so you know how to clean, maintain and look after your pond yourself, and get the most enjoyment out of it.

Pond Cleaning Kent is a family business. I'm the one at your pond, doing the building, cleaning and maintenance. Behind the scenes, my wife Dionne looks after the accounts and invoicing, and my daughter Darcey runs the website, social media and Google marketing.

Frequently Asked Questions

The questions customers ask me most, from the areas I cover to cost, timing and fish safety.

I clean ponds across the whole of Kent, south and south-east London, Surrey and East Sussex. That includes Medway, Maidstone, Canterbury, Tunbridge Wells, Tonbridge, Sevenoaks, Ashford, Sittingbourne, Dartford, Gravesend, Bromley, Bexley, Croydon, Orpington, Guildford, Reigate, Redhill, Epsom, Oxted, Woking, Brighton, Eastbourne, Hastings, Crowborough, Uckfield and Lewes, plus the towns and villages around them. Not sure if you are covered? WhatsApp me your postcode and I will let you know.

The quickest way is to WhatsApp me a few photos of your pond with your postcode, the rough pond size, the type of pond (koi, goldfish or wildlife), when it was last cleaned and what you need doing. You can also call me on 07714 674266 or email me at pondcleaningkent@gmail.com. Quotes are free and there is no obligation.

Every pond is different, so I quote for yours. The price depends on the size of the pond, how much sludge and weed there is, whether there are fish, the filter set-up and access. Send me a few photos and I will give you a clear, fixed quote with no hidden extras. Read more about what affects the cost of pond cleaning. I also offer a price match: I will beat any like-for-like written quote by 10%.

For most garden ponds, I recommend a thorough clean once or twice a year, typically in spring and autumn. How often depends on pond size, fish stock, surrounding trees and filtration.

Autumn (September to November) is best for most ponds, with spring (March to May) a good second choice. I avoid big cleans in hot summer weather and in deep winter, when fish are less able to cope. See my guide: when to clean a pond in the UK.

A full pond clean includes sludge and debris removal, cleaning of the pond edges, removal of excess algae and blanket weed, filter and pump inspection, a partial water change, water quality testing and maintenance advice. Every clean also comes with a free fish health check and bacteria treatment.

Absolutely. Fish safety is my top priority. I use gentle, fish-safe cleaning methods and avoid harsh chemicals. For intensive cleans, I can temporarily move fish to holding tanks with aerated pond water.

Not usually. For most cleans the fish stay in the pond while I vacuum out the sludge. A full drain-down is only needed for very neglected ponds, and then your fish are held safely in aerated tanks of their own pond water until the pond is ready.

It depends on size and condition. Small ponds (under 1,000 litres) take 2 to 3 hours. Medium ponds (1,000 to 5,000 litres) take 3 to 5 hours. Larger or neglected ponds may need a full day.

Pond sludge and weed make a great free fertiliser, so they usually go onto your borders or compost heap. If you would rather it was taken away, just let me know when you book.

Yes. I remove blanket weed by hand, treat green water and check the filter and UV clarifier, which is often where the problem starts. I will also advise on plants and shade to help stop it coming back.

Yes. Wildlife ponds are cleaned gently and at the right time of year, so frogs, newts and other wildlife are not disturbed.

Yes. I offer one-off deep cleans and regular pond maintenance visits (monthly, quarterly or seasonal) to keep your pond in top condition all year.
