How Much Does It Cost to Remove Japanese Knotweed?

Japanese knotweed is not only a notoriously invasive and destructive species, but it's also very difficult to remove. The reason it's so hard to get rid of is because regrowth is very common, as it only takes a tiny fragment of the rhizome root to be left in the soil for a whole new plant to grow. This makes the removal process quite lengthy and costly.

How much does knotweed excavation cost?

If you want to go for a quicker approach to Japanese knotweed removal, excavation is a good option - but it does come at a much higher cost.

We use special equipment to dig the Japanese knotweed out of the ground, including the rhizome root system and any contaminated soil. This is then buried in a specialist weed-proof membrane or transferred to a dedicated landfill site where it won't spread or cause problems on surrounding land.

Knotweed excavation starts at £850 +VAT per square metre (based on a minimum area of 10 to 15 square metres). If you choose the excavation and removal option, you will also need to factor in the landfill charge of approximately £85 per tonne of Japanese knotweed waste on top of the cost of haulage and excavation.

We can add an insurance-backed guarantee to any of our Japanese knotweed treatment plans for an additional £75 - giving you absolute peace of mind. Even if we stop trading, you will be covered in the event that the Japanese knotweed returns.
