The First Step to Japanese Knotweed Removal is an Identification

Japanese knotweed is characterised by having heart-shaped leaves, white clustered flowers and steps that zig-zag toward the sky. In winter, you may not be able to see this Knotweed, but this does not mean it is dead, it simply means it is dormant.

This invasive plant has the ability to damage properties. In fact, just having it on your premises can devalue your home by up to 20%. It is extremely difficult to destroy this invasive plant without breaking laws, which is why it’s best to get qualified experts involved.

If you think you have this Knotweed on your premises, contact our management team today.

Can I Complete Japanese Knotweed Treatment Myself?

Japanese Knotweed treatment and removal is an extremely complex process, as the plant is difficult to eradicate. You also run the risk of breaking laws if this invasive plant isn’t disposed of correctly.

If you complete this difficult task alone, you also have no guarantee that it won’t come back the following year. Our management team provides you with a 5-year warranty, giving you peace of mind that this Knotweed will no longer be on your premises.

If you are in need of Japanese knotweed removal and treatment, wait for our management team to deal with the issue. In no circumstances should you chop the knotweed down as it could spur potential new growth. Contact us today!

Is Japanese Knotweed Treatment and Removal Required if I Don’t want to Devalue My Home?

If you have this invasive plant on your premises and you are wishing to sell, you may find it difficult to find a buyer. This is due to the fact that most lenders will not lend out money if they know that this invasive plant is on the premises.

You can ask for evidence from our team to provide to potential lenders so that they are certain that it won’t affect the property’s value. If this information is not provided, you could run the risk of devaluing your house up to 20%, which could take thousands of pounds off the price of the property.

Get our management team in today to ensure that the treatment and removal are done properly.

Brilliant Service! Chris was very knowledgeable and went above and beyond with his service.
Fantastic results after just one spray! Really happy with this company, would highly recommend them, great results and a very reasonable price for the treatment.

Chris inspected a property that we are purchasing for Japanese Knotweed. He was able to view the property at short notice and quick to follow up with us afterwards. Luckily no knotweed was found! We were very happy with the service.
