Signs of Woodworm

The key to stopping woodworm before they cause irreparable harm to your property is identifying them early. You may not realise that you have a woodworm problem until the resulting damage becomes visible. If left untreated woodworm can seriously weaken timber - this may lead to structural failure in your property.

If you have spotted the signs of woodworm listed on this page we would recommend getting in touch with your local branch of Rentokil Property Care. Our qualified and experienced surveyors have years of experience when it comes to delivering professional woodworm treatment
