Why Cheap Knotweed Removal Can Cost You More
Though you may find ‘cheap’ Japanese knotweed removal services online, we would strongly advise sticking with a reputable, longstanding company to eradicate your knotweed problem. Ultimately, this ensures that you save money in the long run and don’t end up having to pay for a service twice as the job is done thoroughly.
Unfortunately, it’s incredibly easy for Japanese knotweed to come back if the problem isn’t resolved appropriately. A thumbnail’s worth of rhizome left in the soil is all it takes for Japanese knotweed to come back and spread again, so you need to make sure the correct treatment and removal plan is in place moving forward. It’s also strongly recommended to have a proper guarantee in place to safeguard you against recurring problems. It’s for these reasons that we are happy to be completely transparent with our pricing.
