Don’t just take our word for it …

We recently purchased a property in the Bromley area. The initial mortgage valuation survey reported the presence of Japanese Knotweed growing on the railway embankment at the end of the garden. The mortgage lender advised that before they would consider approving our mortgage application, we would need to hire a JK specialist to inspect the growth and provide a detailed report on the findings. We duly approached Japanese Knotweed Specialists and Adam came round to carry out a survey. Thanks to his full and detailed report on the Knotweed, our lender was satisfied and (subject to a treatment programme being implemented) approved our application and we were able to proceed with the purchase. Japanese Knotweed Specialists have now commenced their 1st treatment to eradicate the JK and their service is always friendly and helpful.

Dear Adam,
Many thanks for such a speedy turnaround of this report. As I said yesterday, this has been an extremely worrying time for us, but the efficiency, professionalism and helpfulness shown by you and Tanya has been second to none, and has made a difficult situation that bit easier to handle.

Our house purchase was held up when we were refused a mortgage at the valuation stage, when a survey commissioned by the bank showed that Japanese Knotweed could be present on the property. This really slowed down the process. It feels like an unreasonable extra expense and an unnecessary cost. Thankfully, Japanese Knotweed Specialists charged a very reasonable fee to carry out a Japanese Knotweed survey to find there was in fact no trace of the weed on the property, so the sale could go ahead. Thank you Japanese Knotweed Specialists.
