Onoff Posted October 13, 2018 Share Posted October 13, 2018 (edited) Evening, Need some thoughts on this long term damp problem. Terraced house circa 1860. Slate damp course originally. Later "lean to" added on but this has a proper, modern dpc. Gut feel is it's to do with the gutter above and water is filtering down inside through the solid brick wall? Ventilation maybe? Paint is peeling and blistering etc but it's so high up the wall as well as low down. First off the gutters need clearing and the downpipe properly directing to the hopper. The wc is also overflowing but that's an easy fix and I don't think anything to do with the main damp. Edited October 13, 2018 by Onoff Link to comment Share on other sites More sharing options...
Square Feet Posted October 13, 2018 Share Posted October 13, 2018 (edited) I have been dealing with similar issues on the property I am currently renovating. If it was mine I would do all the things you say above, plus maybe look at the leadwork between the extension and the wall as it looks to me as if there is a gap there. An overflowing cistern will dump thousands of litres where it shouldn't be if left untreated for a long time. It may dry out a fair bit now you have sorted that. Can you run a dehum inside to dry it out a bit and see if your remedial work does the trick? ETA - also is the soil pipe leaking? It looks from the wall staining as though it might be.

Square Feet Posted October 13, 2018 Share Posted October 13, 2018 This bit - if the downpipe is spraying water all around when it is in full flow, could it not be getting in here? 1 Link to comment Share on other sites More sharing options...
Onoff Posted October 13, 2018 Author Share Posted October 13, 2018 That smaller waste halfway along the wall is from the bath. Will check that too. 1 Link to comment Share on other sites More sharing options...

Cpd Posted October 13, 2018 Share Posted October 13, 2018 Looks really bad...... all the above but also there are what looks like two misaligned tiles below the roof, is there other damage on the roof ? Link to comment Share on other sites More sharing options...

Misaligned tiles, just below the stack, I can see it now you've mentioned it. At the end of the gutter, where it stops the fan light opening is the back bedroom. Some water damage coming in around the chimney as it's stained down the stack in the loft. Link to comment Share on other sites More sharing options...
Declan52 Posted October 13, 2018 Share Posted October 13, 2018 The gutters on that extension don't look right. The end section after the downspout looks like it has sunk. This could be throwing water into the cavity. Is there damp in that room at that corner. There is also some spuds growing in the gutters at the other side. Need to start at the top and fix those tiles and check for any others that are cracked/loose and work your way down. Clean out the guttering and fix that droopy bit. Connect the spout that is hovering in mid air directly into the gutter below. Check to see if that lead is still sealed against the wall. It looks like there are a couple of holes at the end.

CC45 Posted October 13, 2018 Share Posted October 13, 2018 Needs redoing from the top down. Years of neglect there really. Will it slow up your bathroom makeover? Link to comment Share on other sites More sharing options...

Jeremy Harris Posted October 16, 2018 Share Posted October 16, 2018 There's a lot of staining below that overflow pipe that's sticking out to the left of the upper window, right next to the SVP. Makes me wonder if there is, or has been, a slight drip from that which has been running back under the pipe and down the wall for years. The give away is that the wall and the SVP look clean above the height of that overflow. Link to comment Share on other sites More sharing options...
Onoff Posted October 17, 2018 Author Share Posted October 17, 2018 (edited) Looking at the very first photo could it be that though the roof ostensibly has a decent fall down the length it should also have a slight fall away from the long side? Water is maybe running under the lead? Edited October 17, 2018 by Onoff Link to comment Share on other sites More sharing options...
Simplysimon Posted October 17, 2018 Share Posted October 17, 2018 rising damp only rises 1.2m, anything above that and it's coming from above Link to comment Share on other sites More sharing options...

This pillar with the render, plaster coming off is about halfway along the length of the lean to. I'm not sure without looking whether the twinwall polycarb is let into the wall in a slot or it just butts against the pebbledashing and the flashing sits down on it which is my suspicion. If as I say the roof slopes towards the wall despite sloping along the length water will be running straight under the flashing. Hose test time maybe! Going to try and look this weekend.
