5* Trust Pilot review: Huge relief! “It was so helpful and a huge relief to be able to contact Japanese Knotweed Ltd and get a quick response that was able to confirm that the plant I had discovered coming over my fence was NOT the dreaded knotweed! Fantastic service. Thank you so much!”
If you are buying or selling a property that is affected by Japanese knotweed, we recommend a Japanese knotweed survey.
Lenders are often concerned about the damage that Japanese knotweed can do to a property – this raises questions about its ‘saleability’ in the future meaning lenders want to understand the potential risk of losing money on a property that could reduce in value. This can make it more difficult to secure a mortgage.
Japanese Knotweed Ltd is a fully accredited business and we use the risk table laid out by the Royal Institution of Charted Surveyors (RICS) to help understand and categorise the level of risk that the knotweed presents on the property. The level of risk is defined by the proximity of the knotweed to the habitable area or the property boundary, and if any structural damage has been caused.

Getting a Japanese knotweed mortgage
If you suspect that there is knotweed on the property you wish to buy or sell, you may have trouble securing a mortgage. We can conduct a professional Japanese knotweed survey for you that will include a detailed account of our findings, photographs, location plans and confirmation of the knotweed RICS property at risk category along with a Knotweed Management Plan (KMP) proposal.
Armed with the results of the survey and the management plan, you will be able to ensure a much smoother buying or selling process. Click the button below to learn more or book a survey.

What is Japanese knotweed damage?
In its drive to expand, Japanese knotweed will exploit existing weaknesses, gaps or cracks in property, underground services, walls, concrete, foundations, fences, out-buildings and conservatories. As it grows and expands, it will increase the expansion of the gap or crack and cause damage to walls, ruin garden fences and break through into buildings.
In its search for moisture, the rhizomes will forge their way through structures without regard for their purpose – including underground pipes and electrical cables.
In addition to the damage root systems can cause, it can also cause problems above ground. Japanese Knotweed grows large ‘bamboo-like’ stalks. These stalks grow together in tight clumps. They grow large green ‘shovel-shaped’ leaves which can cover a wide area. This growth will block areas, recuse usable areas of the garden and also prevent natural flora and fauna from growing.

Removing knotweed from a residential property by excavation
Over a period of three days, we completed full excavation to a depth of 1.3 metres with all waste being removed to landfill. We also installed root barriers that would ensure any potential fragments of rhizome would not be able to grow into new plants. The area offsite will continue to be treated under a herbicide treatment programme to ensure no further problems will occur in the future. The picture shows how clean and tidy the garden was left after we’d completed the contract.
