    Hi All, Probably a simple question but driving me nuts. Fitting an interior sill, the gap at either side of the sill (wall back to window) is different by about 20mm. If I fit the sill butted to window, cut at same depth right across, I end up with the overhang and sill horns different at each...

I've taken the spindle cap off, undone screw underneath but there's no gland nut (pic attached). What do I...

    24mm Joists

    Doing a bit of decorating and had a sneaky look under the floorboards to see what the story was, floor bit bouncy (to very bouncy) in places. Much to my surprise the joists are 24mm thick (by about 100mm). House was built early 60s, would that have been common? Seems massively undersized, closer...

    Two C16 Grades - what's the difference?

    Picked up two differently marked C16 timbers from local builders merchant, who informed me they'd both cut the mustard in terms of being used as structural timber in a floor i.e. building control would be happy.

    Hi All, Looking some practical advice on how to layer up SLC up to 55mm. Floor goes down in the middle to lowest point of 55mm, and gradually then rises to edges where i'll need to feather edge it or take it to 1mm max. I was thinking I need to use two different SLCs, one of the reinforced...

    Concealed Mixer Head Replaceable?

    Hi all, Retiling a shower and wondering if I can replace shower head (and pipe) on pic attached. It comes out and down well under head height for me. Do these screw off right back to the wall? Don't want to try in case they don't. Would this be a right pain to remove completely? Assume you take...

    Bypassing Joist

    Hi all, Looking for some suggestions about how I get 22mm copper pipes around/through a joist (97mm). Notching on top isn't an option as notch would be too deep. I think I can go through middle via drilling holes but plumber is talking about not having enough space to get joins in and solder...

Pic attached shows two 22mm rad pipes coming out of the hallway (concrete floor) into suspended timber floor and are messing with my plans to run a joist along the wall where they come out.

    Land Drain - where can I drain it to?

    Hi Everyone, I have quite poor drainage around the house - clay soil, slope down towards house, and in periods of heavy rain the water can rise up to worrying levels at the front of the house (I think over the years the ground level has been raised up too much as well). Almost impossible to...

    Full fill Kingspan K103 Insulation Condensation Risk

    Hi All, For a couple of reasons (radiator pipes, ceiling height, avoiding blocking air vents), and to avoid a lot of faffing about with all those things, I'm stuck with 100mm joists in a suspended timber floor. From what I can tell the only insulation that will achieve the u-value I need (0.25)...
