CH_18 Posted February 9 Share Posted February 9 (edited) I think I know the answer to this. Had our front door fitted this week and to my suprise was fitted without a sill? Door has been installed within the cavity to avoid thermal bridging but now without the sill exposes a possible water ingress issue. The cavity below the door is lined with DPM and concrete filled so is sitting on this. Before they fitted the door I had the DPM pulled up at the front and lapped backwards behind the door so the door could sit on this but they trimmed it off flush at the front?? I queried the fitting at the time of install and they assured me it was correct, it was for thermal bridging and a sill couldn't be fitted for the level access for regs? The rainwater running down the door can now flow behind the visible DPC and soak the cavity filled concrete? 1. Is this wrong and 2. How do I fix it?

Temp Posted February 9 Share Posted February 9 (edited) When we built the regs required a level entry to meet part M of the building regs. Basicaloy followed this example from the web. Edited February 9 by Temp Link to comment Share on other sites More sharing options...
CH_18 Posted February 10 Author Share Posted February 10 (edited) Yeah I've seen that posted here a few times. That's got a sill by the looks of it 🙄 Edited February 10 by CH_18 Link to comment Share on other sites More sharing options...
Mr Punter Posted February 10 Share Posted February 10 Yes it is wrong. If this is supply and fit, get them back to sort it. It needs a cill set to overhang the brickwork. They may need to scrap this one and start again. Water will be pissing into the cavity. Link to comment Share on other sites More sharing options...
dpmiller Posted February 10 Share Posted February 10 chop a row of brick out and set a sill in? Link to comment Share on other sites More sharing options...
joe90 Posted February 10 Share Posted February 10 That is crap and I can’t understand a company doing that when obviously wrong?, surely they should have either fitted a cill or told you one should be fitted before their door was fitted. I would get a manager out to explain themselves and to either remove it and provide one with a cill or pay for what @dpmiller says above. I hope you have not paid yet?

CH_18 Posted February 10 Author Share Posted February 10 I don't think I can chop out a row of bricks and set a sill in because the cavity is concrete filled, so even if I do take a row out I can't set a sill back far enough under the door 😔 Annoying Link to comment Share on other sites More sharing options...
kandgmitchell Posted February 22 Share Posted February 22 That's awful, surely they don't think this is OK? If no joy what about this aluminium type(but the door version)? It'll need the frame coming out to do it properly but it would avoid taking bricks out. Link to comment Share on other sites More sharing options...
kandgmitchell Posted February 22 Share Posted February 22 Sorry thats the clip to join lengths together but the cill is the same and you get the idea. Should have gone to specsavers! Link to comment Share on other sites More sharing options...
Alan Ambrose Posted February 22 Share Posted February 22 Presumably you have some step detail outside? Bit of a bodge, but can you get some ~1mm stainless sheet under the frame. If so, a custom cut and bent cill sealed with and embedded with the right mastic? Even better if you can get dpc and 1mm SS under. Link to comment Share on other sites More sharing options...

If the door is sitting on concrete and the cavity is full of concrete you have a very large thermal bridge. Any chance of a sketch of a cross section please?
