    Chimney damp - losing our minds

    I've seen other posts on this forum in this vein but still need advice. We have been suffering with a damp issue related to our chimney stack. It's a 1950s house, hipped roof. The stack is quite large with two pots. All fireplaces in the house have been blocked off for years (by previous owners)...

    No vapour barrier behind plasterboard - does it matter?

    Recently posted about getting some plastering work done and whether to board and skim or just chip off old skim and re-skim... Trades did the latter in most places but we decided to board in some small areas for various reasons. On one wall in particular, they put 10mm gyproc board on the wall...

    How to skim over this old wall with some blown plaster?

    I've seen lots of threads about this sort of issue but every case has details that are slightly different to ours... and I want to get the right advice here. We are renovating our 1950s house and all our walls are like this (see below). Previously, all walls had wallpaper - which was carefully...

    Bathroom extractor fan recommendation?

    I am looking for a really good bathroom extractor fan. At the moment we have a pretty weak one with an extraction rate of 27 l/s. It's positioned right over the shower yet we get bad condensation on the walls. A friend has an inline system with a humidity sensor. It automatically varies rate of...

    Skimmed walls - small hollow patches

    1950s house, old skim was in a bad way so got builder to remove all the loose stuff. Some quite large patches were hacked off and we could see places that had been filled and sanded over by someone in the past. Walls were then thistle bonded and plastered over. Was allowed to dry without heat...

    Trying to get my head round return flow temp, delta t, BTUs... help!

    Screed not drying at all?

    We had 70mm of floor screed (sand cement with accelerator) laid on 9 March. It was tested on 5 April and found - via a carbide test - to be too damp to lay laminate flooring. We had a number of locations tested and they were all roughly the same. One, for example was 4.6%. (Laminate flooring...

    Heavy condensation in under stairs cupboard

    We moved to a 1950s detached house in September which has a cupboard space under the stairs. I've noticed some quite heavy condensation inside it which you can see in the attached pictures. The cupboard does smell faintly damp and there was a lot of mould / blown plaster on the walls here before...

    Floors dug up - should we put in underfloor heating??

    We are in the middle of some major renovations in our house which include excavation of most of the ground floor to put in a new subfloor, DPM, insulation and screed.

    Removing grille / cover from CenterRad radiators

    Am choosing some new radiators and the price of Myson round tops appears to have gone through the roof since I last bought some (2019). I'm now considering the cheaper CenterRad ones (which I know are made by Myson) and a plumber told me you can take the grille / cover off these and flip them...

    Planning to remove all cavity wall insulation!

    I mentioned the problem with damp associated with our external walls on a previous post but have since learned more about the issue after a lot of research and investigating. Am looking for any advice folks here can share. I've come up with an approach that I think is probably the safest but...
