Detecting Leaks Around Your Windows
Seals that are broken, pulling away, missing or which are damaged as a result of ageing or long-term weather exposure will cause windows and doors to leak. Furthermore, the sealant or window putty used to seal the glazing beads on wooden windows may crack and allow moisture into the gazed areas of your windows. In addition, when the glazing putty on your steel windows cracks or a section falls out moisture will corrode the steel window frame.
These are the most obvious areas where leakages occur!
However, the most undetected area for leaks at windows is the junction between the window frame and the brickwork, plasterwork and window sill. As a matter of fact, it is one of the most common defects that I have found in both new and older homes.
There are multiple ways to detect leaks around your windows and doors:
- On the outside of your home, check the areas where two different materials meet. This includes your door and window corners and frame.
- Look for cracks in the door itself and in window panes.
- Examine the existing caulking (sealing) and window weather stripping and weatherboards on doors. Make sure both are in good condition. In addition, leave no gaps or cracks.
- If you can see daylight around a window or door frame, there will be a leak.
- Shut a window and check for gaps in which you can insert the paint scraper. If you can easily insert the scraper under the closing part of the window, it is probably not watertight!
