Do Surveyors Look for Japanese Knotweed?

Surveyors routinely examine properties for Japanese knotweed (Fallopia japonica), an invasive plant known to cause significant issues, especially in regions like the UK. Given the plant’s potential to diminish property values and induce structural damage, identifying and reporting its presence is pivotal for surveyors.

Here’s what surveyors typically check for:

  1. Plant Characteristics: Recognizing the plant involves checking for its heart-shaped leaves, bamboo-like stems, and white blossoms during late summer.
  2. Growth Patterns: The dense, rapid growth of Japanese knotweed often overshadows and suppresses native plants. Surveyors look out for such growth patterns.
  3. Location: It’s important to note the plant’s proximity to infrastructures like buildings and walls. Its aggressive roots are known to inflict damage.
  4. Previous Treatments: A surveyor might question past knotweed treatments, which can reflect the current level of infestation.

The detection of Japanese knotweed during a property survey can influence both its market valuation and mortgage feasibility. Mortgage providers frequently express hesitancy in approving properties infested with the plant, given the associated risks of structural harm and recurring management expenses.

In specific scenarios, a systematically crafted management strategy can appease lenders and prospective buyers, signifying that there are measures in place to tackle and contain the issue.

Why Might Conveyancing Surveyors Recommend a Dedicated Japanese Knotweed Survey?

  1. Dense Growth: Thick vegetation in gardens can obscure the view, making it challenging for surveyors to detect Japanese knotweed.
  2. Risk Assessment: A specialized survey can give a clearer picture of the extent of infestation and related risks.
  3. Liability & Due Diligence: A focused survey underlines the surveyor’s commitment to thorough scrutiny, ensuring all potential issues are highlighted.
  4. Expert Evaluation: Surveys by experts with in-depth knowledge about invasive plants offer detailed insights on the severity of the infestation and its potential impact.
  5. Mortgage Lender Requirements: Certain lenders mandate a dedicated knotweed survey before greenlighting a mortgage to gauge risks related to property value and structure.
  6. Management Plan: These specialized surveys often incorporate a management plan, laying out suitable control methods. Such plans play a pivotal role for property owners, potential buyers, and lenders, showcasing proactive and responsible management efforts.

In essence, a focused Japanese knotweed survey equips conveyancing surveyors with a thorough understanding of the property’s condition, empowering them to guide their clients accurately and address any concerns stemming from the plant’s presence.

Do Surveyors Look for Japanese Knotweed? the presence of Japanese knotweed on a property can lead to a series of implications, ranging from financial concerns to legal issues. Here’s a breakdown of what might ensue:
  1. Property Valuation Impact: Japanese knotweed can result in a significant decrease in property value. Its invasive nature and potential to cause structural damage make properties less appealing to prospective buyers.
  2. Mortgage Difficulties: Many mortgage providers are hesitant to lend on properties infested with Japanese knotweed. If they do, it’s often contingent on a professional management plan being in place or proof of treatment.
  3. Structural Damage: Japanese knotweed’s roots, or rhizomes, are robust and can exploit cracks in concrete, tarmac, and brickwork, leading to considerable structural damage. This can include compromised building foundations, walls, and other structures.
  4. Legal Implications: If knotweed spreads from one property to a neighboring property, the original property owner may face legal consequences. The affected neighbor could potentially sue for damages or the cost of treatment.
  5. Cost of Treatment: Effectively treating and managing Japanese knotweed can be expensive, especially if it’s extensively spread. While there are chemical and non-chemical methods, complete eradication can take years.
  6. Ecological Impact: Japanese knotweed can suppress the growth of native plants due to its dense growth pattern. This can harm local biodiversity and disrupt the ecosystem.
  7. Disclosure Requirement: When selling a property, sellers might be legally obligated to disclose the presence of Japanese knotweed to potential buyers.
  8. Management Plans: Once identified, property owners often need to develop a comprehensive management plan. This plan details the measures to control and eventually eradicate the plant. It can also be used to demonstrate to potential buyers or lenders that steps are being taken to address the issue.
  9. Monitoring: Even after treatment, properties are usually monitored for a few years to ensure that there are no new growths or resurgence of the plant.
  10. Specialized Insurance: Some insurers might provide coverage specifically tailored for damages caused by Japanese knotweed. However, this can sometimes come at a premium.

  2. Management Plan: Lenders are more likely to be reassured if a professional Japanese knotweed management plan is in place. This plan should detail the measures being taken to control and eventually eradicate the plant.
  3. Treatment Guarantees: Some companies that specialize in the removal of Japanese knotweed offer guarantees for their work, usually for a period of 5-10 years. A guarantee can provide further assurance to the mortgage company that the problem is being managed and that there’s recourse if the treatment isn’t effective.
  4. Ongoing Monitoring: Demonstrating that the property will be regularly monitored for any resurgence of the plant after treatment can also be reassuring.
  5. Disclosure and Honesty: Being transparent about the issue, any past treatments, and current conditions can help in building trust with the mortgage company.
  6. Insurance Coverage: If you have specialized insurance that covers potential damages caused by Japanese knotweed, this could be another point of reassurance for the lender.
  7. Mortgage Company’s Policy: Different lenders have varying policies when it comes to Japanese knotweed. Some might be more lenient if conditions are met, while others might be more stringent.
