Japanese Knotweed and Mortgage Problems

Japanese knotweed can cause problems when applying for a mortgage as the aggressive growth pattern of Japanese knotweed is capable of exposing weaknesses in hard engineered structures such as concrete, tarmac, brick walls and foundations.

Specific problems caused by Japanese Knotweed are:

• Damage to retaining wall structures, paving and tarmac areas
• Damage to building foundations
• Damage to flood defence structures
• Reduction in land values
• Aesthetic issues
• Restriction of access

All of which are reasons why mortgage lenders are reluctant to lend on properties with Japanese Knotweed.
