Japanese knotweed Removal Wales
Japanese knotweed has an incredibly robust plant structure, allowing it to grow in almost any environment. This is largely why the removal of Japanese knotweed is so difficult.
With its ability to tolerate low temperatures, it can rapidly spread through any gaps in structures like bricks or concrete. By choosing a trusted Japanese knotweed removal specialist in Swansea, you can ensure your infestation is removed permanently, and avoid the cost of knotweed damage in future.
Japanese knotweed Removal Cost in Swansea
There is no one fixed Japanese knotweed removal cost, as this depends on the treatment plan and extent of your infestation.
Our careful and methodical treatment of Japanese knotweed using appropriate chemicals and dosages over time allow for successful control of the Japanese knotweed, as well as prevent it from spreading. We offer a 100% guarantee that our herbicide treatment programmes will prevent any future above ground growth. However, this treatment method does not guarantee that the underground rhizomes will be removed.
Excavation involves digging up the entire root system, and is the only method which allows Japanese knotweed to be removed fully and permanently. It’s important for works to be carried out by experts such as TPK knotweed, to ensure complete removal, as a minute piece of rhizome has the ability to regrow and lead to spreading.
Japanese knotweed in Swansea, Wales
Swansea is a Welsh city located along the south coast. Much of the city was destroyed during World War II, when it was a particular target because of its industrial importance. Nowadays very little of Medieval Swansea remains, although it is still possible to see some of the ancient city in the roads and the ruins of the castle.
Japanese knotweed grows indiscriminately and with alarming speed, giving no consideration to city heritage – new or old. Resilient, it is capable of pushing through tarmac and concrete as readily as protected city ruins at great cost. As Wales’ most populous city outside of Cardiff, Swansea is under particular threat from knotweed, which spreads with incredible ease from property to property.
We’re proud to be able to provide Japanese knotweed removal in Wales, benefiting both residential homes and city infrastructure from our experience, expertise, and keen attention to customer service.
