Identify. Isolate. Eradicate: Mastering the Science of Timber Decay.
Woodworm & Timber Decay
The Basics: Why Wood Rot Happens
Timber decay is caused by fungi that need two things to survive: wood (food) and moisture (usually a moisture content above 20%).
There are two main culprits you need to know:
1. Wet Rot (The Common Nuisance)
Cause: Constant, localized leaks or dampness.
Appearance: The wood becomes dark, soft, and eventually crumbles.
Behavior: It stays where the water is. If you fix the leak, the rot usually stops spreading.
2. Dry Rot (The Serious Threat)
Cause: Initial moisture (20–30%), but it is much more aggressive.
Appearance: Wood shrinks and cracks into a distinctive "cuboidal" (brick-like) pattern. You may also see white, cotton-wool-like strands called mycelium.
Behavior: This is the "cancer" of building decay. It can grow through brickwork and mortar to find and "eat" healthy timber in other parts of the house.
The Treatment Process
Regardless of the type of rot, the recovery process follows these four steps:
Stop the Source: Fix the leak or dampness immediately. Without water, the fungi cannot survive.
Strip Back: Remove all decayed wood. Pros usually cut away an extra "safety margin" of healthy-looking wood to ensure no microscopic spores remain.
Chemical Shield: Apply fungicides (often boron or copper-based) to the remaining timber and surrounding masonry via spray or injection.
Replace: Install new sections of timber that have been pre-treated to resist future attacks.
Thermal Imaging Cameras
Essential Damp Detection Tools
Building inspectors primarily rely on two pieces of tech to find hidden moisture: Moisture Meters and Thermal Imaging Cameras.
1. Moisture Meters
These provide the "hard numbers" to prove how much water is actually present.
Pin-type (Invasive): These have two sharp probes that must be pushed into the material (like wood or plaster). They measure the electrical resistance to give a precise moisture content reading.
Pinless (Non-invasive): These use radio frequencies to scan near the surface. They are great for checking delicate finishes without leaving holes behind.
2. Thermal Imaging (Infrared)
Think of this as the "scout." Instead of checking one spot at a time, it scans entire walls instantly.
How it works: It maps surface temperatures. Because moisture is usually colder than its surroundings (due to evaporation), it shows up as a "cold spot" on the screen.
The "Heat" Exception: It can also find hot water leaks by highlighting unusually warm areas behind a wall.
Rising Damp & DPC Injection
Chemical damp proof injection is a remedial treatment primarily used to control rising damp in masonry walls where the original Damp Proof Course (DPC) has failed or is absent.
The process involves creating a new, effective water-repellent barrier:
Drilling: A series of horizontal holes are drilled into the mortar joint at the base of the affected wall, typically about 150mm above the exterior ground level.
Injection: A specialised, silicone-based damp proof cream or fluid is injected into these boreholes using a low-pressure cartridge gun or pump. The active ingredient is usually a silane or siloxane compound.
Diffusion and Curing: The injected cream or fluid then diffuses (spreads) throughout the porous brickwork and mortar surrounding the injection points. It reacts chemically, often curing over a period of 4 to 8 weeks, to line the capillaries (tiny pores) within the masonry.
Barrier Formation: This cured chemical forms a horizontal, water-repellent barrier that stops ground moisture from rising up the wall via capillary action, effectively creating a new DPC.
