Residential Knotweed Management Plans

Japanese knotweed growing out of control on an estate in Wales

Sie Surveys & Knotweed Management Plans

The size, scale and location of every infestation is different. So we make visits to residential sites and conduct a Site Survey, documenting:

The extent of the infestation
We can confirm this by both photographic evidence and, if necessary, by flying a drone over the area to obtain aerial images.

The location of the infestation
We take into consideration the proximity of the infestation to your property and to those of neighbouring areas, and also consider if there the area of Japanese knotweed growth can be lost to use for the period of treament.

The maturity of the infestation
Our team are able to identify the maturity of the infestation and at what point in the growing cycle the plant is – this will affect the timings and the type of treatment plan recommended.

Access requirements
We will need to determine if the infestation is easily accessible and if there is any other vegetation growing nearby that needs to be preserved – ie your favourite shrubs or roses.

Next Steps

The Knotweed Management Plan (informed by the Site Survey) will detail how TCM will remove and eradicate the infestation.

Once instructed to proceed TCM will take care of the whole operation, keeping you informed at every stage. All our work is guaranteed for 10 years (this time scale can be extended) and once works are complete we also issue our Lloyds backed A+ rated Insurance Backed Guarantee (IBG).

If you are trying to sell your property you will need both a Knotweed Management Plan and an IBG to satisfy most UK lender’s concerns and allow the sale, or mortgage application, to continue.
