The problem with this old chimney is that there is no lead tray built in to stop the damp passing down through the chimney from external to internal : The roof space is part of the internal part of the chimney stack and there fore it is not normal for water ingress to occur : so water penetration is either coming in down the face of the chimney stack due to a fault with the lead flashing are in some cases the felt but water penetration that comes down the inside of the chimney stack always is the result of damaged pointing of brickwork or the chimney cap or condensation in the flue liners but a lot of times in my experience it is because there is no lead tray to stop damp passing down through the chimney

Thanks Neil, I'm a student surveyor just looked at a 1960s bungalow with water staining to the rendered chimney in the loft space. But meter readings to the chimney breast where it meets the ceiling in the room below are very low so I was airing towards there not being a significant issue and I think you have just confirmed that for me. Thanks again ! 👍

Hi Neil refreshing to hear such down to earth but skillful opinions on such a matter. I have a mid terraced victorian house built in the 1860s and someone had boarded up the fireplace before I bought the house. Not long after I moved in I noticed patches appearing arround the chimney breast, and some on the adjacent outside front wall not long after I painted. Had lots of people giving their opinions which always seemed to conflict. One builder suggested putting airvents in the chimney breast by drilling holes through and putting plastic airvents on but I do not know how thick the sides are. After watching and listening to your video and seeing how you view such matters I wondered if you had any ideas about my issue please? Sorry to be so forward, keep up your good and informative work Neil, so refreshing. Kind Regards. Henry Brannigan.

This is very informative, I’ve spent over £500 on exterior remedies and it doesn’t make any difference, my problem is it has after several years now started to show on the bedroom chimney brest so not sure on my options now other than the £2100 quoted to remove the chimney stack or to use something I’ve heard of called storm dry in the summer🤷♂️🤷♂️

I think what would help this situation is to 'Seal' the brickwork on the chimney stack above the roofline. There are several good brick seals that you paint on. Often two coats ensure a good seal. Water should then, technically, run off the brickwork and down the roof rather than soak into the stack and down into the loft and sometimes down the breast into the house below. Certainly worth a try if you suspect this is the cause of damp on your chimney breast.

I know it’s well ventilated roof space but I would also say condensation at times is forming on the masonry and sulphate salts then running down the chimney breast. Great vid

Thanks for posting this, its quite reassuring. Got similar on my loft space chimney brickwork, with white mold growing on the roof timbers where they meet the chimney. My loft space has zero air movement as when roof was replaced 10 years ago the installers stapled up some kind of sheeting all over the inside of the roof - totally blocking any air flow. Think I'll go and cut some of it away and see if things improve.

I have this exact issue, I have spent a lot of money reflaunching the chimney, repointing and new lead work. Still came back. Last Jan I paid roofer to paint a sealant on exterior chimney, not much success. Damp patches only when we get prolonged rain.

Airflow guys. Imagine an extractor fan in the wall of the loft. The air flows in all night and day then the extractor fan comes on for 25 minutes 4 times a day. Say 8am , 11 am, 2 pm and 5pm. Problem solved.

in my house the people finished the attic it has windows at each end and chimney is offset to one side and we stopped using chimney for heating with high efficiency direct vent heater so now wall that covers chimney is damp and getting black mold from moisture tried waterproofing chimney and we put the ventilated caps back on chimney to help ventilate inside I was thinking of putting waterproof foamboard and vapor barrier to room to keep room dry and mold free from chimney moisture hoping the moisture will evaporate out inside of chimney out through top caps. is there anything else i can do to get rid of moisture?

My bungalow has these rain marks running down both ends of my chimney and salt marks in my loft but I do have damp coming through the ceiling. It doesn’t drip, just shows up on the ceiling as damp. I’m so worried about being ripped off by a tradesman. Any ideas so I know what to expect one to say? My partner is going to check the chimney stacks on the roof when the weather is better. Flashing, cracked mortar or absorbing bricks is all we know could be the problem.

I've had the same problem with a damp and stained wall and ceiling around the chimney breast. A roofer re-did the lead flashing, and applied a coat of Thompsons brick sealer. Everything was fine for about 3 years, then this winter following the relentless rainfall the damp returned worse than before. Following research I found that Thompsons brick sealer only protects brickwork for 1-3 years at most. I believe the problem is porous brickwork and the inferior brickwork product has broken down. So, scaffolding has gone back up, the leadwork all looks fine, and I'm going to apply 2 heavy coats of Climashield Masonry Protection Cream or StormDry Masonry Protection Cream. These products are supposed to protect brickwork for up to 25 years. They aren't cheap but they do work well ! I've used Climashield before on an external wall and you can see the rainwater just bead and run off the wall during heavy rainfall, it never soaks into the brick or mortar lines.

hang on .. youre saying there is visible evidence of water ingress from above roofline and you're saying 'ignore it, it will likely evaporate and not get as far as the ceiling or wall of first floor bedroom' .. I think that's a bit 'hope and pray' if you don't mind me saying .. the water ingress you describe is 99% sure to be due to the ONLY thing that makes a seal against the weather ie. the lead soakers and step flashings checking the leadwork costs nothing and re-doing them if they've been poorly installed or perished or missing etc is the ONLY way to sort the issue (and it shouldn't cost a great deal)

Sorry but this is not 100% normal when damp, mould comes to walls and house! It's simple answer after 100 years of using chimney It's time to rebuild, make new pointing, make new concrete on top etc. Only because you don't see clearly where is problem doesn't mean there is no problem, when you buy new home and see bricks in loft like on your video you gonna say - OK it's normal? You really think you gonna use hundreds years old houses without full renovation forever?
