Warm, 18°C, windy with a few showers.
In one corner of my living room is a damp patch in the wallpaper. Coincidentally, it’s above a ventilation vent. It’s the vent that housed a wasps’ nest last year, if you remember. There is am easy way to investigate, take the vent out and have a look.
The result, one surprise and one confirmed suspicion. First, the surprise- I have cavity wall insulation. Having lived here for 20 years, I should have known.
I scraped out some mortar and pieces of brick. They must have been the means that carried water involved wall inner layer. The mortar was quite damp to the touch. Guilty as charged. As you can see in the photo, there is a stubborn piece that is tightly wedged in. It has refused to budge today, but I’ll have another go tomorrow.
…but is it enough?
