Ive noticed a few companies offering knotweed eradication guarantees. Are they worth the paper they e written on?
That depends upon the company issuing the guarantee. We’ve seen some companies offering guarantees where the guarantee period is longer than the time the company has been in business. You need to check out their track record, take references, and if necessary, get a lawyer to check the guarantee wording. Environet has offered 5 year guarantees for its eradication treatment since 2004. These state that if the knotweed comes back, so will we at no further cost to the customer. Where our Xtract method is used, we offer extended guarantees for 20 years.
