Warranty

We offer a warranty for Japanese knotweed eradication to give our clients reassurance that we have completed our programme of works successfully. The warranty can be applied to any of the other weeds we treat (giant hogweed, Himalayan balsam etc.). The warranty will cover the cost of further treatment and repairs to property in the unlikely event that re-infestation occurs. Further details can be found below.

IWA will help you choose warranty cover that best suits your requirements.

Why is a Japanese knotweed eradication warranty important?

Warranty cover is important because Japanese knotweed is a difficult weed to eradicate. Regardless of the method used to eradicate this weed, there is risk that one small part of the plant may not be treated or removed correctly. This small piece of Japanese knotweed may go unnoticed for quite some time. In this unlikely event, without warranty cover, the client may have to spend more money on having the Japanese knotweed treated or removed, especially if it has taken a long time for it to re-emerge. If there is warranty cover in place then it is simply a case of contacting the Japanese knotweed contractor and asking them to remedy the situation.

What length of Japanese knotweed warranty cover should I choose?

The length of warranty cover will depend on your situation and the Japanese knotweed to be eradicated. A very small, juvenile Japanese knotweed plant may not be well established and therefore it may be easier to eradicate than a large infestation that has occupied a site for decades. In this case, a short warranty may be appropriate whereas a much longer warranty may be more suitable for the large, mature Japanese knotweed. IWA advise our clients on an individual basis.

Another thing to consider is what do you intend to do with the property where the Japanese knotweed infestation is? If you are planning on selling or remortgaging the property before all traces of the Japanese knotweed infestation are gone then it is advisable choose warranty cover for a minimum of a 3 year period. Why? Mortgage lenders are reluctant to lend money for properties with faults. Japanese knotweed can cause serious damage to properties and it can spread rapidly if it is not treated. Mortgage lenders want the reassurance that the Japanese knotweed will be eradicated by a professional company that offers a warranty for their work.

Warranty Options

There are several options for warranty cover in order to meet specific requirements. All of our work relating to Japanese knotweed and invasive weed eradication is underwritten by our insurance. To discuss what option would be best for your situation, please contact our team.

Insurance-Backed Warranty

We offer insurance-backed warranty cover for a period of up to 12 years.

They cover:

• Monitoring the area for the duration of the warranty.
• Reporting
• Remediation of any re-infestation that may occur.
• The cost of repairing any damage to structures or hard surfaces as a result of the re-infestation.

Bonded Warranty

We offer bonded warranty cover for clients that want the security of knowing that if Invasive Weeds Agency went out of business there is still insurance cover in place to cover the cost or treatment of any re-infestation that may occur and the cost of repairing any damage that has arisen as a result of the weed problem re-appearing.  This form of insurance is only necessary if the contractor fails to maintain their insurance for the period of active warranties.
