Repairing wet rot damage for the Greater Manchester Police
Timberwise were instructed to carry out a damp and timber survey for the Greater Manchester Police (GMP). Timberwise were specifically asked to investigate approximately 21 upper floor timber windows to the end elevation of the GMP building. At the survey, it was highlighted that several of the windows were suffering from various levels of rot and in need of repair.

A difficult task to the untrained eye is identifying whether the wood rot fungus, that was affecting the police station, was wet rot or dry rot. The timber felt soft and spongy to touch and looked darker than the timber that surrounded it. The paint was also damaged and flaky and along with a damp and musty smell. With this in mind, the fungal decay was confirmed as wet rot by our rot specialists.
Wet rot is a generic term that is often used to describe various fungal rots, these fungi can cause damage by getting their food by breaking down the walls of wood cells. Over time this leads to a loss on strength in the timber.
The severe outbreak of confirmed wet rot was also within the neighbouring timbers surrounding the window, this was mainly a result of; defective rainwater goods, inadequate window beadings and a lack of routine maintenance. The combination of these defects, allowed surface water to penetrate the fabric of the building over a period of several years. As the moisture levels built up within the timbers it created the perfect conditions for wet rot and for the timber to decay.
Timberwise’s experts found several parts within the roof section that also needed to be treated, along with several timbers that needed to be replaced due to the extent of the decay. Timberwise North West identified that many of the window beadings were in need of replacement as they were allowing water to penetrate behind the glass causing wet rot to the window frames.
As the windows were at the upper levels of the building, access to them was through the use of a powered access platform, Timberwise were able to provide a safe, modern and cost-effective way of working at height. Due to the severe nature of the damage, a considerable amount of repair work was needed to rectify the devastating effect of the wood rot.
All decay was removed prior to application and the moisture content of the remaining wood was found to be below 18%. The repairs that Timberwise carried out were a combination of replacing timbers and innovative resin repairs, this entailed applying a layer of Dry Flex resin to the bottom rails and frames of the windows. Additionally, any defected timbers that had decayed were cut back and replaced with treated timbers to match the existing timbers. This plastic repair compound is used for the fast repair of timbers and can be sanded and painted on the same day, this means disruption on the everyday operations of the building is minimised and GMP could go about their day to day operations.
