  1. Nick ... what do you think of my 2 photos. (The right side of the photos are the original end wall of house). Is it "cavity" that might have cable tie issues causing damp??
  2. Actually, my photos could be mis-leading. The "right" side of the photos are the end wall of the original house. The "left" side relates to an extension - a very old extension. There is a RSJ just about visible at the top of my photos.
  3. This is fascinating! Have a look at these old photos. They are from another part of the kitchen. Do these photos help confirm your theory about the "ties"??
  4. Wow - the plot thickens! In case of doubt - I am showing the way I measured the 400mm. See the other image with the orange circles. Where are the "cavity wall ties" ? What do they look like? What should I google to see examples? We put the sliding door in 25 years ago ... builder that did job may not have been meticulous.
  5. The thickness of the wall that the sliding door is fitted to = 16.5 inches.
  6. Thanks again Nick, You are very helpful. (Incidentally, I was amazed when the cylinder split open ... "Indoor water feature" ... nice!) The wall does seem thick .. more that a brick plus mortar. Separate issue in same room. See photo of kitchen sink - same bloody kitchen! There is clear damp here. I wonder is it straightforward?? Is it just because water got under the tiles at point "A" - near the coke can?? Is it rising damp from that??
  7. Thanks, 1. This is close-up of the shower drain. It does not appear to be sealed ?? *** Should I seal it? 2. I can block the air brick - it's just a legacy thing ..There is no extractor.. The kitchen is large and well vented (probably too well vented!) 3. Cavity wall? I'm not a builder and am not sure of the answer. However, it's a red brick house built in 1904. What's the likely situation? Two other possible complications: 4. May not be relevant but we installed underfloor heating (water) in the entire house (all floors) - 25 years ago. No known leakage. 5. The hot water cylinder/immersion burst about 15 years ago ...there was too much pressure in it and the metal casing split ... flooded the kitchen .... a fair bit of water but probably only for 20 minutes ... as we turned off water supply.
  8. Thanks all for responding. I have a theory... See photo and notice the green arrow pointing on the top left... point "A"... this is drain from a 5 year old bathroom. Would a leak from the drain in the bathroom have caused damp in point "B". Point C has some damp too.
  9. Hi, greetings from Ireland! See photo attached of my large kitchen. No ventilation issues. House is redbrick build in 1904 and renovated 25 years ago. See the "green circle number 1"... This is clearly rising damp. However, see also green circle 4 and 2. These are giving damp readings of 20% and 30%. That whole internal wall is about 10 metres long with multiple damp patches. See also that the photo shows the external of the kitchen (yellow). Note that the flat roof is not perfect but is 5 metres away from some of the damp. QUESTION: Have I both rising damp AND another form of damp? Is it possible that there is a "pool" of water hidden in the wall??
