Pond Maintenance
Regular maintenance keeps the everyday jobs under control: clearing debris, looking after plants, and checking that the pump and filter are working properly. We care for garden ponds, koi ponds, wildlife ponds and ornamental ponds across Kent, London and the South East.
We keep ponds ourselves, so we know how useful a manageable routine can be. Tell us which jobs you want help with and what you already do. We can then agree regular visits, seasonal help or a one-off visit as part of our wider pond care services.
Starting with a full pond clean
When we take over regular maintenance, we generally like to start with a full pond clean. It gives us a clean starting point and lets us bring the pond up to a high standard before the regular visits begin. From there, we can keep on top of the work and help keep it clean, healthy and running well.
That first clean also helps us get to know the pond inside and out: its shape, size and depth, the equipment in the water, and the pumps, filters and pipework outside it. Knowing the whole setup makes it easier to plan the routine and explain any improvements we think would be worthwhile.
We will talk through the initial clean and quote for it separately from the regular maintenance visits. We will also agree the right approach for the pond and its wildlife before starting any work.
How our four-weekly maintenance rounds work
We usually arrange regular maintenance every four weeks and group visits into area rounds. We agree the jobs around your pond, its equipment and the care you want to do yourself.
Some filters need cleaning more often between visits. A lightly managed wildlife pond may need less intervention, while a koi pond can need more frequent attention. We will explain the checks to keep doing and agree a routine that fits.
Four-weekly visits are 28 days apart, so there can be about 13 visits over a full year. The price is per visit, rather than a monthly subscription.
Why regular pond maintenance helps
Leaves, plant debris and fish waste soon add up. You might notice that the filter needs cleaning more often, the pump intake is getting clogged or the plants are spreading further than you want.
Keeping on top of those jobs makes the pond easier to enjoy and gives us a chance to spot changes in the equipment or water before they become a bigger problem. The routine should suit your pond and the care you already provide.
What’s included in a maintenance visit?
We agree the work around your pond, its equipment and what needs attention. Typical jobs include:
- Removing surface debris and accessible organic waste.
- Cleaning skimmers, pump intakes and filters as needed.
- Checking the water level and circulation.
- Inspecting pumps, pipework and fittings.
- Looking at fish behaviour and the overall condition of the pond.
- Trimming plants or dealing with seasonal jobs where agreed.
Some visits involve more filter work; others need more time on plants or accumulated debris. We will explain the scope of the visit and which checks and small jobs still need attention between appointments.
Spring and autumn pond maintenance
The jobs change through the year. A regular round gives us a chance to adjust the work as the pond changes.
In spring, we check how the pond and equipment have come through winter, clear accumulated debris and plan the plant care needed as growth picks up.
In autumn, the focus is on leaves, dying foliage and excess plant growth, so less material is left to break down in the pond over winter.
Filter servicing and equipment checks
The filter is often the part of the setup that needs the most regular hands-on care. We service a range of systems, including:
- Pressurised canister filters.
- Box and gravity-fed filters.
- Multi-chamber filter systems.
- Oase ScreenMatic filters.
- Drum filters and other advanced filtration systems.
The work depends on the unit. It may involve cleaning foams or screens, flushing waste outlets, checking media and seals, or discussing worn parts that need replacing.
If the existing setup is struggling or taking too much work to look after, we can discuss suitable filter and pump upgrades. New equipment is quoted separately.
Regular filter care in practice
Jean’s West Malling pond is one example of the filter work involved in regular maintenance. Natalie cleaned the existing Oase ScreenMatic filter, with its screen, collection tray and foams. The photograph shows the foams during the visit.
A self-cleaning drum reduces some manual filter-cleaning work, but the rest of the system still needs attention. Our Cuxton drum-filter maintenance project records a visit after a power cut stopped the filter. We got it running again and made a further check later that month.
Pond plant care
Plants are part of the pond, rather than something to clear out at every visit. We look at what is growing well, what has become crowded and where access or water flow is being restricted.
Where needed and agreed, the work can include:
- Pruning and thinning aquatic plants.
- Dividing and repotting water lilies.
- Reducing excessive oxygenating plant growth.
- Thinning crowded marginal plants.
- Replanting with suitable aquatic planting materials.
Blanketweed and algae
If algae or blanketweed keeps returning, we look at what is contributing to it as well as the growth itself. Removing waste, managing plants and maintaining the filter can form part of that work.
We can discuss suitable treatments where needed, alongside the changes that may help reduce regrowth. For larger ponds and more complex systems, longer-term nutrient management may be appropriate.
When a full pond clean is needed
We generally like to start with a full pond clean when we take over regular maintenance. A larger clean can also be useful when sludge, crowded plants or neglected areas are beyond the scope of a routine visit.
We assess the pond, its fish and wildlife before agreeing the work. Depending on the job, this can include:
- Removing fish to suitable temporary holding where needed.
- Draining the pond to carry out the agreed clean.
- Removing accumulated sludge and debris.
- Cleaning filters and accessible pipework.
- Refilling and getting the equipment running again.
A full clean is quoted separately from regular maintenance. It may also be arranged alongside repairs or relining where required.

Maintenance that fits your pond
Some owners want help with the filter but enjoy looking after the plants themselves. Others would like us to handle more of the regular work. We will talk through what suits you and what your pond needs.
Whether you need ongoing visits, seasonal support or help getting a neglected pond back under control, we can discuss a sensible starting point.
We look after our own ponds as well as those of our customers. Find out more about Matt, our experience and the team behind That Pond Guy.
Ongoing pond care in Maidstone
Our Maidstone cleaning and maintenance project shows how regular care and occasional larger jobs can work together. In her 2022 review, Hazel describes years of pond maintenance, cleaning and replanting when required, and advice about her pump, filter and UV equipment.
“Matt has maintained our pond for years.”
Hazel, Maidstone, 2022
The original review and project photographs are available on the project page. Her account is a useful example of assessing the equipment as well as the appearance of the pond.

Pond maintenance questions
Choose a question to read the answer.
How much does pond maintenance cost?
Most visits cost £60–£180 plus VAT. The price depends on your location, pond, equipment and the work needed. Send us your postcode and photographs for a quote. Full cleans, repairs and new equipment are quoted separately.
How often should a pond be maintained?
For most ponds needing regular care, we generally start with a maintenance visit every four weeks and group visits into area rounds. The right interval still depends on the pond, fish, filtration and the care you provide between visits. A drum filter can reduce manual cleaning, while a lightly managed wildlife pond may need less intervention. Some filters need cleaning more frequently than our visits, so we explain the checks to keep doing yourself.
What does professional pond maintenance include?
Professional pond maintenance typically includes removing organic debris, cleaning skimmers and pump intakes, checking water circulation, inspecting filtration systems, monitoring fish health, and identifying early signs of problems such as algae growth or equipment failure. Depending on the pond, maintenance may also involve plant management, blanketweed control, filter servicing, and water quality assessment.
What happens if a pond is not maintained properly?
Without regular pond maintenance, organic waste and sludge gradually build up on the pond floor. This leads to poor water quality, unpleasant smells, algae outbreaks, reduced oxygen levels, and increased stress on fish. Over time, neglected ponds often require far more disruptive and expensive work such as full drain and clean services or major filtration upgrades.
Is pond maintenance different for koi ponds?
Yes. Koi ponds require a higher level of maintenance than wildlife or ornamental ponds. Koi produce more waste, are sensitive to water quality changes, and rely heavily on efficient filtration. Koi pond maintenance focuses on keeping ammonia, nitrite, and phosphate levels under control, ensuring filters are functioning correctly, and maintaining stable oxygen levels.
Do I need pond maintenance in winter?
Yes, although winter maintenance is usually lighter. In winter the focus is on keeping water flowing, preventing excessive debris buildup, and ensuring pumps and filters are protected from frost. Autumn maintenance before winter is especially important, as removing leaves and organic material helps reduce sludge formation and water quality issues during colder months.
How often should pond filters be cleaned?
This depends on the type of filter and stocking levels. Some filters require regular light cleaning, while others are largely self cleaning. Drum filters and advanced systems still benefit from inspection and servicing to ensure sensors, spray bars, and waste outlets are working correctly. Over cleaning filters can be just as harmful as not cleaning them at all, as it can disrupt beneficial bacteria.
Can pond maintenance help with blanketweed and algae?
Yes. Regular pond maintenance plays a key role in preventing algae problems. Removing organic waste, managing plants correctly, and maintaining filters reduces nutrient levels that algae feed on. Where algae or blanketweed is already present, professional treatments can be used safely, alongside long term nutrient management, to reduce regrowth.
When does a pond need a drain and clean?
We generally like to start with a full clean when we take over regular maintenance. It helps us bring the pond up to a good standard and get to know its shape, size and equipment. It does not mean draining it at every routine visit or simply because a set number of years has passed. We assess the condition, planting and wildlife before agreeing the initial work, and quote for that clean separately. Cleaning can also form part of an agreed repair or relining project.
Is professional pond maintenance safe for fish?
Yes. Professional pond maintenance is carried out with fish safety as a priority. Care is taken to avoid sudden water changes, preserve beneficial bacteria, and minimise stress. Where deeper cleaning or treatments are required, appropriate precautions are taken to protect fish health throughout the process.
Can pond maintenance improve water clarity?
Maintenance can improve clarity by removing suspended debris and helping filtration work properly. Green water, blanketweed and disturbed sediment need different responses, so we first look at the cause. Clear water alone does not confirm that conditions are suitable for fish; water testing and observation are still important.
Do you maintain wildlife ponds as well as koi ponds?
Yes. Wildlife ponds require a different approach to koi ponds. Maintenance is usually lighter and focuses on preserving habitats, controlling excessive plant growth, and maintaining water flow without disturbing wildlife. Any work is planned carefully to avoid harm to frogs, newts, insects, and other pond life.
How do I know what maintenance my pond needs?
Every pond is different. Factors such as pond size, depth, fish stock, filtration type, surrounding environment, and water source all affect maintenance requirements. An initial visit allows us to assess the pond properly and recommend a realistic maintenance plan based on its actual condition.
Can regular pond maintenance save money long term?
Yes. Routine pond maintenance helps prevent major problems such as pump failure, filter damage, fish health issues, and severe sludge buildup. Addressing small issues early is far more cost effective than carrying out major corrective work later.
Do you offer one off maintenance visits?
Yes. One off maintenance visits are available for customers who need help at specific times of year, before selling a property, or when a pond has been neglected. After an initial visit, we can also advise whether ongoing maintenance would be beneficial.
What areas do you cover for pond maintenance?
We take maintenance enquiries across the Kent, London, Essex, Surrey and Sussex areas we cover. Choose the relevant area above, then send your postcode and pond photographs so we can confirm the current round, suitable work and visit arrangements.
How do I arrange pond maintenance?
