    Rain-sensor autocloser for top-hung Velux window - any suggestions?

    Can anyone suggest a basic rain sensor autocloser that I could retrofit to an existing top-hung Velux window? The only ones I can see on the Velux website are for centre-hung windows. Ideally, the window would be opened manually, and close automatically if and when it rains - so no need to...

    What is causing this UFH rattling noise - any ideas?

    It's coming from our underfloor heating circuit, probably in the ceiling void between the ground and first floors, and is amplified by the pipes passing through a cavity wall into our garage (where they then drop down to the UFH pump and manifold near ground floor level). It's a rapid rattling...

    How to insulate an airing cupboard's external-facing wall?

    We have an airing cupboard where the right hand side is constructed against an external brick cavity wall (uninsulated). There is a 40W electric cupboard heater at the bottom of the cupboard, which ought to be enough to keep everything nicely warm. However, the air temperature doesn't rise above...

    Should I use GRP to repair leaking fillet on concrete roof?

    Our garage flat roof is made of 100mm thick concrete (1950s) which tends to leak where it butts up against the side brick wall of the house. I repaired it 15 years ago with a 45 degree mortar fillet about 100mm wide (front surface) - but now this is leaking in a couple of places from cracks...

    External Wood Storage Solution - Ideas Needed Please!

    Due to a lack of workshop space I have to find a way to store my 200+ stock of 2x2s, wooden trim, copper pipes, curtain rails, carpet trim etc. *outside* of the house. I'm talking about long thin stuff here - not boards. A lot of it is in 8ft lenghts but there are offcuts that are maybe only...

    Decking - Grooves or No Grooves?

    Hi It's been a while since this has been discussed, so I would like to ask everyone for their views on whether I should buy smooth or grooved decking for our back garden (west-facing). What are the pros and cons of each, and the implications for maintenance, safety etc? Thanks!

    Best way to stick stainless steel to aluminium?

    I've got to join together about 6 metres of aluminium and stainless steel "L" angle strips, like this (end view): ¬L There will be a vertical load on the s/s (left hand side of the diagram) equivalent to say 50kg max over any 100mm length of the join - the extreme left hand end will be...

    What to do about cracked UFH screed

    Hi Work is finishing on our new build extension - single room 6m x 7m. We have wet UFH (John Guest SpeedFit) with 3 loops in 75mm screed (4-1 sand mortar plus fibres) and we plan to glue a very good quality engineered oak board to it. We left the screed 90 days to cure/dry, before...
