    What foam gun?

    It does - the brass thumbwheel behind the trigger, and that's what I do too

    What foam gun?

    I've had really good experience with this. https://www.cwberry.com/concept-foam-gun Pricey, but strips down easily if it does get clogged. I use it infrequently and leave a can on for 2-3 months at a time. I do sandpaper the end of the brass nozzle occasionally to get a good clean squirt, and it...

    Replacing lead lined Tudor style windows

    Personally I would avoid black uPVC altogether. The thermal expansion of uPVC is huge (0.07-0.08mm/m/degree), and black windows just get hotter which exacerbates the problem. e.g. a 1m tall window, with a 50 degree range (say -10 in a very cold winter, to a surface temp of 40 degrees with the...

    Need help with damp!

    Whatever you do, you don't need to lose them. They will be really hard encaustic tiles. Photograph them, lift them, clean them up (which can be a fair bit of work - we did ours with a rotating wire brush to get mortar remnants off) and then relay them. They are definitely worth keeping. Likely...

    Sick of Mould behind radiator

    Originally cavity walls were designed to isolate the joist ends from the wetter outside wall so they didn't rot off - i.e. nothing to do with insulation. Then, in the era of lime mortar and plaster, and breathable materials, cavity walls were designed with airbricks in to the cavity so that any...

    Sick of Mould behind radiator

    You can't change physics. The radiator creates airflow through convection. Obviously the air drawn over the back of the radiator is humid enough, and the wall is cold enough for the wall to be below the dew point so you're getting liquid condensation and mould. You can only increase the wall...

    Buying a property that had an extension built with no sign off but permission granted

    It's 2009, so whatever happened it's way past enforcement. Use your own eyes, and also get a decent survey done. If it all looks good and you like it, go ahead with an indemnity if your BS insist. If you are concerned, walk away - lots of other properties out there. Whether you get a sign-off...

    Quality of newly installed wooden sash widows?

    Sounds like a result, although obviously hassle. Good on the company for at least taking ownership.

    Frankly, that is cobblers up until someone shows me the wording from an actual insurance policy that states this exclusion for 20 year old works. It certainly isn't in mine. And if an extension is looking good with no cracking after 20 years, I think it's fair to say it's OK. We bought a very...

    Quality of newly installed wooden sash widows?

    Those internal micro cracks by the latch show a lack of attention to detail, but TBH are unlikely to be detrimental to performance - I doubt the latches will fall off! Even so, I expect you paid a lot of money and have every right to expect a perfect product. Some screws are self-drilling but...

    Quality of newly installed wooden sash widows?

    Looks like however they have made the joint has split the rail. Send the pictures to the MD at the company and ask if he is happy with this because you are not. They have a nice website. I suspect they won't want those pix against their name. Edit your post to remove it for now, and tell them...

    It's 20 years ago!. Are you bothered? certainly the LA won't be, so this is just a tick-box exercise. As long as it surveys OK, take the path of least resistance - maybe just accepting the conveyancer says it's OK, or maybe an indemnity if necessary (a waste of time and money, but sometimes...

    Unidentified conduit

    I suspect there's more around than you think. Son's house in E17 has just been completely rewired but had singles in conduit like this in many places. 18 months ago he did have the CU replaced and all circuits passed testing at the time....

    Outbuilding Raft Foundation

    Here's a raft I did for a garage. It's 150mm in the centre with an approx 300x450 edge "beam". My C.Eng MICE son sprinkled holy water on my design and said it would be fine, as it has proved. https://community.screwfix.com/threads/garage-work-in-progress.222282/ The stepped edge has proved 100%...

    Kitchen extractor advice sought

    Yes - was connected to one of these https://www.quirepace.co.uk/wp-content/uploads/2023/07/Nurse_carrier_543.png and we ended up having to install a valve to block of the service tube when not in use to stop the chimneying effect of the air being pushed through all the time by the pressurised...

    I hope you've found all the comments helpful. It sounds like you have your head around this challenge, and like you, I like to find solutions. I'm 100% sure it can be made to work - it's just getting all the factors in play worked out. FWIW, in a different world, I have installed 160mm tube...

    Look, I'm not a ventilation specialist, I am however a specialist in air movement in pipes for central vacuuming and pneumatic transport, hence the advice to talk to a specialist in this field. Input the parameters in to AI and see the answer! There are several challenges - enough flow to push...
