Japanese knotweed removal

Japanese Knotweed Removal in the North West & Birmingham

Trusted, Local Help from Japanese Knotweed Plus Ltd

Japanese knotweed (Fallopia japonica) is no ordinary garden weed. It grows fast, spreads silently underground and can damage structures, hardstanding and property values if it’s not dealt with correctly.

If you’ve spotted something that looks like Japanese knotweed – or your buyer’s mortgage lender has raised a knotweed query – you need professional Japanese knotweed removal and clear, written reassurance.

That’s where Japanese Knotweed Plus Ltd comes in.

Why Japanese Knotweed Removal Matters

Left untreated, Japanese knotweed can:

  • Undermine walls, fences, patios and driveways.

  • Spread into neighbouring land, causing disputes.

  • Make selling or remortgaging a property difficult.

  • This leads to expensive legal and remediation costs.

Because it spreads through its robust rhizome (root) system, simply cutting it down or digging it up yourself often makes the problem worse. Small pieces of rhizome can grow into new plants and spread the infestation further.

For this reason, professional Japanese knotweed removal and management is strongly recommended – and in many cases, required by lenders.

Why Choose Japanese Knotweed Plus Ltd?

At Japanese Knotweed Plus Ltd, we specialise in surveying, treating and managing Japanese knotweed for domestic and commercial clients across the North West and Birmingham.

Here’s what sets us apart from many of our competitors:

1. Free, Local Site Surveys

We offer free Japanese knotweed surveys carried out by a PCA-accredited surveyor who knows the local area and soil conditions.

  • No call centres

  • No subcontracted surveyors from miles away

  • Just clear, practical advice from a local specialist

During your survey, we will:

  • Confirm whether the plant is Japanese knotweed.

  • Map the infestation and assess the risk.

  • Advise on the most suitable treatment or removal method.

  • Discuss timescales, costs and what your lender or buyer will need

Important: If a treatment plan is required, the survey and full written report to satisfy your buyer’s mortgage company will not cost you a penny.

2. 10-Year Insurance-Backed Guarantees

We know that lenders, buyers and solicitors want certainty.

That’s why, with each treatment plan, we offer a complimentary 10-year insurance-backed guarantee (IBG). This gives peace of mind that:

  • The knotweed is being professionally managed.

  • Long-term protection is in place.

  • Your property is more attractive to buyers and lenders

Our guarantee reflects our confidence in the effectiveness of our work and helps protect the value of your home or investment.

3. Financial Advantages for Domestic Customers (No VAT)

As a smaller, specialist company, we can offer a more personal, cost-effective service than many larger firms.

For domestic customers, there is an additional benefit:

  • No VAT charged on the treatment cost

This can make a significant difference to the overall price of your Japanese knotweed removal and helps keep our service affordable for homeowners.

4. Environmentally Conscious Knotweed Treatment

We are committed to protecting the local environment while controlling the spread of Japanese knotweed.

Our approach includes:

  • Carefully selected, professional-grade herbicides

  • Targeted application methods to minimise chemical use

  • Protecting nearby lawns, shrubs and trees wherever possible

  • Working in line with industry best practice and PCA guidance

Our goal is to control and eradicate Japanese knotweed while keeping your garden or land as healthy and natural as possible.

How Our Japanese Knotweed Removal Process Works

When you contact Japanese Knotweed Plus Ltd, this is what you can expect:

Step 1: Free Site Survey & Assessment

Our PCA-accredited surveyor will visit your property to:

  • Confirm the presence of Japanese knotweed (or rule it out)

  • Assess the severity and extent of the infestation.

  • Identify any risks to buildings, boundaries and neighbouring land

You will then receive clear advice on the most appropriate treatment options.

Step 2: Tailored Treatment & Management Plan

Every site is different, so we create a bespoke Japanese knotweed management plan for your property. This may include:

  • A multi-year herbicide treatment programme

  • Monitoring visits to check for regrowth

  • Advice on preventing the spread during landscaping or building works

If you are buying or selling a property, the management plan and report will be written in a way that satisfies mortgage lenders and solicitors.

Step 3: Environmentally Sensitive Herbicide Treatments

We use targeted herbicide applications to weaken and kill the Japanese knotweed rhizome system gradually. This is often the most practical and cost-effective solution for domestic properties.

Treatments are timed to maximise effectiveness and minimise disruption, with visits typically arranged during the primary growing season.

Step 4: Monitoring, Completion & Certification

We continue to monitor the site during and after treatment. Once the knotweed has been successfully controlled and two full consecutive growing seasons have passed with no regrowth, we can:

  • Update your management plan.

  • Issue a completion certificate.

  • Confirm that the treatment programme has been completed

This documentation is handy when selling or remortgaging your property.

Frequently Asked Questions about Japanese Knotweed Removal

Do I really need a professional to remove Japanese knotweed?
Yes. Because Japanese knotweed spreads via its rhizome system, DIY attempts often cause more harm than good. Professional treatment is typically required to meet mortgage lenders’ requirements and maintain property value.

How long does Japanese knotweed treatment take?
Most treatment plans span several growing seasons, with regular monitoring. Industry bodies and lenders recommend this approach because it addresses the plant at the rhizome level.

Will my mortgage lender accept your report and guarantee?
Our survey reports, management plans and 10-year insurance-backed guarantees are designed to meet the expectations of UK lenders, buyers and solicitors.

Is the survey really free?
Yes. Your Japanese knotweed survey is free, and if a treatment plan is required, the survey and full written report for your buyer’s mortgage company won’t cost you anything.
