Japanese Knotweed Survey Report

Japanese Knotweed Survey Report

 

Our survey process in brief

We will do our best to visit your site at a convenient time that suits you. Our PCA certificated surveyors will carry out a detailed investigation of your site and neighbouring land . The survey is based on a visual observation only; no digging of soil to disturb the weeds and plants will be undertaken. Our surveyors are highly trained to identify Japanese Knotweed throughout the year as long as no effort to hide the signs of the plant has been made prior to the survey. 

You will be provided with an electronic version of the Japanese Knotweed Survey Report normally within three working days after our visit. Our survey cost starts at £180. This cost will be refunded if a treatment course with Japanese Knotweed Plus Ltd is required by you. Please, refer to our T&Cs for more information regarding our surveys. 

Our survey report

We will produce a high-quality print-ready PDF-version of the report that will satisfy your solicitor and buyer’s mortgage lender. The report will include general information about the company, our team, and essential pieces of legislation related to Japanese Knotweed. 

A detailed map of your site and surrounding area will be displayed. Your property will be highlighted on the map. If Japanese Knotweed is present on your land or on neighbouring land the area of infestation will be schematically shown on the map, e.g. by green dots. The dimensions of the infested area and the shortest distance to the house will also be indicated.

High-resolution photographs of the infested area accompanied by detailed descriptions will be shown next in the report. We will show and comment on any other plants that have been identified as suspicious by our surveyors.

In the final part of the report, the risk of Japanese Knotweed to the property will be estimated using a chart introduced by RICS in 2012. The risk is subdivided in four categories depending on the distance from the infested area to the property boundary or habitable space (house, conservatory, garage). If the infestation falls in to the categories 3 or 4, further investigation by qualified contractor is automatically required and management plan should be established.

Japanese Knotweed risk categories established by RICS

In the case of the risk matching the category 3 or 4, we will offer a tentative management plan in the survey report. A two-year treatment course using herbicides will normally be applied to slowly kill the plant followed by two-year monitoring to ensure that the probability of regrowth in the future will be significantly low.

Total cost of the treatment/monitoring course will be indicated at the end of the report. If you a decided to go ahead with treatment more detailed management plan will be produced. The management plan will be upgraded at all stages of the treatment course and forwarded to the client. 

The survey report for non-domestic clients will be built using similar structure.
