Do I still need to repair my leaking roof or any other maintenance problems?
Yes, in order to not hinder the efficacy of the Schrijver System, the property has to be kept in a dry and waterproof condition and adequately maintained. The Schrijver System is not designed to rectify a building’s existing, outstanding maintenance issues that could cause ingress of water. If in any doubt, please consult an independent Chartered Surveyor on how to rectify and repair such issues. The Schrijver System is designed to remove excess moisture directly from external walls. The guarantee covers that the installation is completed according to specification. Actual results may vary.
