Japanese Knotweed is an invasive species of plant that is active all year round. The plant hibernates in winter making you think your problem has disappeared when in reality the real problem lies under the ground. The plant works off an underground root system called a Rhizome. This Rhizome can spread far further than what you can see above ground, making it a really pesky plant to get rid of.
Here at S4JK we are heavily invested in making sure our staff are up to date with all current legislation and PCA guidance. We are members of the Invasive Weed Control Group that keeps us up to date with all the latest research and methodology within our industry. We also invest in our staff in various courses concerning eradication to make sure our methods are the best on the market.
This nightmare plant can cause damage to buildings, hard standings and other structures. Banks are reluctant to lend on properties where Japanese Knotweed has been to left to cause havoc, however most mortgage lenders WILL lend if a proper management plan is in place from a professional company like ourselves.
Japanese Knotweed causes problems and hold ups with mortgages, re-mortgages and planning permission. Problems can also be caused by spreading onto neighbouring properties, which can inflict serious legal implications. We continually help people with these problems with our expert knowledge of invasive plants and current legislation. We act fast on your problems and take the stress away. We will find the best suitable option for you at a great price.
