Our Japanese knotweed treatment methods
No two infestations are identical. We assess your site’s specific conditions to choose the right strategy:
| Treatment Method | Best For | Typical Timescale | Key Advantage |
|---|---|---|---|
| Herbicide Stem Injection | Residential gardens, tight boundaries, preserving nearby foliage. | 2–3 growing seasons | Minimal ground disruption & highly targeted. |
| Excavation & Off-Site Disposal | Construction sites, instant property sales, development plots. | 1–3 days | Immediate eradication of the root system (rhizomes). |
1. Herbicide control
Using targeted stem injection or foliage spraying, we apply specialist herbicides at the precise point in the growing season to destroy the weed from the inside out without harming surrounding plants.
2. Excavation and removal
If you are planning a renovation or extension in Stroud, our team can physically excavate the entire root and rhizome system. We handle all waste disposal safely and legally under strict UK regulations.
The risk of untreated Japanese knotweed in Gloucestershire
Japanese knotweed can grow up to 10cm a day, puncturing brickwork, foundations, and drainage systems. Beyond the physical damage, it can strip up to 15% off your property value and cause mortgage companies to reject buyer applications.
Important Legal Note: Property owners face legal penalties if they allow this invasive species to spread into neighbouring land. Early professional intervention is vital.

Frequently asked questions
You are based in Hampshire, will I be charged extra for your team to travel to Gloucestershire?
No. We treat infestations across the South of England and Wales daily. The price we quote for your site survey and treatment plan is fixed. There are no hidden travel fees or regional surcharges for Stroud clients.
I am trying to sell my house right now. Can your service save my sale before it falls through?
Yes. Mortgage lenders usually reject buyers the moment knotweed is spotted. However, because we are Property Care Association (PCA) members, lenders will typically approve the mortgage as soon as we complete our survey and you sign up for a managed treatment plan backed by our insurance guarantee. We can fast-track this paperwork to keep your sale moving.
How long does it actually take to completely get rid of the weed?
It depends on your timeline. Our targeted herbicide program takes 3 to 5 years of controlled management to completely kill the root system. If you are developing land or need it gone immediately to build an extension, our excavation service physically digs out and removes the entire root system in a matter of days.
Why can’t I just cut it down or spray it with heavy-duty weedkiller myself?
Cutting the stems actually triggers a survival mechanism underground, forcing the roots (rhizomes) to spread rapidly horizontally. Over-the-counter weedkillers only burn the surface leaves; they do not reach the deep root system. DIY attempts usually make the infestation wider, more aggressive, and more expensive for us to fix later.
Does the insurance-backed guarantee transfer to a new buyer if I sell the property?
Yes. Our insurance-backed guarantees (IBGs) stay with the property, not the owner. If you sell your home or business premises in the future, the remaining years of protection automatically transfer to the new owner, giving them, and their bank, total peace of mind.
