Harwich has a rich maritime history, and its Old Town conservation area contains some of the finest examples of Georgian and early Victorian architecture on the Essex coast. Many of these properties were built using ships' timbers — recycled oak from decommissioned vessels — which gives them enormous character but also makes them vulnerable to specific types of timber decay, including Death Watch Beetle, which thrives in old hardwoods.
Our work in Harwich frequently involves treating historic timbers with specialist deep-penetrating gels and boron-based preservatives that eradicate active infestations without damaging the wood or affecting the building's appearance. For structural timbers that have been weakened by decay, we provide reinforcement using resin repair systems and, where necessary, splice in new seasoned oak to maintain the building's integrity.
The Dovercourt area of Harwich has a more mixed housing stock, including Victorian terraces, inter-war semis, and modern estates. Here, the issues are similar to those found across the rest of East Anglia — rising damp, condensation, woodworm in roof timbers, and wet rot in ground floor joists. We provide the full range of KDS services in Dovercourt, from DPC injection and PIV installation to exterior wall coatings and structural waterproofing.
