Wood rot in sash windows: what is the approach?
Sash windows, characteristic of many Amsterdam canal houses and townhouses, need relatively many joints and room to move in order to slide. That very construction makes them more prone to moisture ingress than a fixed window frame.
Why sash windows are vulnerable
The sill and the tracks the window slides in catch water and dry more slowly than other parts of the frame. Combined with the many seams between the different wooden components, wood rot develops here sooner than in a fixed window.
Our approach to sash windows
Where necessary, we dismantle the sash window to properly assess and treat all sides, mill out affected wood, and repair it with a wood repair system that moves with the sliding mechanism. Afterwards, we lubricate and readjust the window so that it slides smoothly again.
DIY, or better to have it done?
With the right preparation and materials, some parts of wood rot repair can be done yourself, especially for small-scale, easily accessible work. Where it gets trickier — working at height, uncertainty about the condition of the surface, or work that causes more expensive damage if done wrong, such as wood rot or damp problems — it's wise to have a professional painter take a look before you start.
Not sure what's sensible for your situation? During a free, no-obligation assessment we give honest advice: sometimes a touch-up is enough, sometimes a more thorough approach is needed. That advice is free and non-binding, even if you decide to do it yourself.
What affects the cost
Naming a specific figure for wood rot repair is difficult without knowing the situation: the surface area, the condition of the surface, accessibility and the number of coats together determine the price. Poorly maintained work needs more preparation — such as wood repair or extra sanding — and therefore weighs more heavily than the painting itself.
