    Wet Windows

    The point is to have airflow so if under the fireplace leads to a cellar with good air circulation that could work but you'd still need vents somewhere at the top of the flue if the chimney has also been capped and sealed at top...

    Dark patches around plasterboard patch repairs after painting

    What was behind the phone socket that you removed? If it was a wire through the wall to the outside this could be bridging any cavity and/or causing a cold spot and the damp? Solve the problem if you can Good luck

    DPC failed is it too high?

    If the damp is not just on external walls but also internal/party wall and most near the chimney breast then that could be at least part of source of problem ... doesn't suffice to cap a chimney - if no ventilation you can apparently get condensation. If there was a chimney breast that's been...

    Solution for damp patches on chimney breast?

    I had same issue in an upstairs room where chimney breast had been removed. Remember if hydroscopic salts from plaster/chimney it's getting moisture from the air in the room so solution is easy stop the moisture getting to the plaster. Paint over and 1m either side with an oil based paint like...

    Repainting badly painted brick wall

    If there's algae think you need to treat with a fungicide to remove it? You could also look at using something like emperor masonry paint which (so the manufacturers claim) can go on top of existing paint (haven't used it myself but says can go on top of existing exterior paint on their...

    Pointing repairs

    Hi I've bought a property, the survey said minor pointing repairs needed, had a 'specialist' company round specialist in exterior decorating and brickwork, who said whole wall needs repointing (2.5k plus cost of scaffolding C. 35m2 in South london). The guy didn't even go up a ladder to feel...

    Gutter section failed after only 3 years

    Thanks looked to me like water was coming out of the bottom of the gutter and also (last video) drips through the joint to next section. That's why I thought must be failing. There's less of a gap/visible light for the section nearer than further a long

    wall deflecting inward where chimney breast removed

    Hi Woody Thanks for that I think the rationale was walls are meant to be vertical structurally and aesthetically he only means the top few courses The wall will be supporting the roof structure I guess. So at the least I 'think' it needs looking at close up to see if the pointing/mortar...

    wall deflecting inward where chimney breast removed

    Hi all, am looking at buying a property built c 1900-1910 where some courses of bricks next to a former chimney breast appear to be deflecting inward. Survey [level 3] says "To the rear wall, there is evidence that makes us consider that there was a chimney stack, which has been removed and...

    Damp patches upstairs where chimney breast previously removed

    " Is the flue ventilated top and bottom? It needs to be. If the chimney served an upstairs and a downstairs fireplace, each will have its own flue. The old fireplace may have had builders rubble hidden behind it. Dig this out." thanks JohnD. No ventilation that I can see either in the bedroom...

    Damp patches upstairs where chimney breast previously removed

    Thanks, Noseall. Can you say more about what sort of 'SBR slurry' and 'prepared render backing' is needed? If I ve understood you right it's moisture from inside the room, even tho I keep it well ventilated. What about covering with a oil based paint primer? [suggested here...

    Cavity wall insulation vs insulating plasterboard

    "The main cold issue is just in this one room, and it also has a couple of damp spots also" I was looking into this myself [cavity wall vs IWI] and in at least a couple of places it reminded me that damp insulation is no insulation....so sort out the cause of your damp spots first..... if...
