Trouble is Sam, is that the damp industry is renowned for deceitful companies. Going around with a damp metre sticking the 2 pins in the walls and saying oooooh damp ooooh damp ere as well. Gotta cut plaster off a metre high, tank it, damp course it, etc etc. That'll be 6 grand thank you. Renowned!
Misdiagnosis will always be an issue but there is people doing the correct courses … following the British standards and always trying to improve knowledge … not everyone wakes up everyday trying to rip people off
The vent for a log burner isn't for wood gasses release it's that the log burner draws oxygen from the room and can cause hypoxia or to much carbon dioxide ,a fresh air kit on back of log burner solves this problem and no vent would be needed as burner draws air from outside .
Let's talk about surveyors /linked to mortgage lenders coming into the industry and panicking as they have never seen damp or spoken to a builder in there life, just come from uni. They panic and over egg severity, I've seen house sales fall through and lenders not lend for one cold spit on a wall! Have a pop at them mate not tradesmen!
The internal floor is solid concrete I think he said. Not likely to have a DPM under. Possible migration from the solid floor bridging the internal wall (through mortar joints) and/or the DPC in the wall, provided it’s got one, may be bridged but I do notice an air brick which must be above the DPC. Perhaps the DPC is very much less than 150mm there could be ‘splashing’ on the leaf and eventually migrating through.
Hmmm, I live in a solid wall home. The north facing living room is COLD as hell in winter (Doesn't help that there's a cellar underneath) Over 20 years ago some previous owner had put some kind of damp rods in (in the brick). But last year we had terrible rain which went on for ages and the walls felt wet to touch. Mind you the internal walls are covered with a thick Anaglypta wall covering half way up - which probably doesn't help
that 200 year old house was probably sand and cemented and gypsumed which caused the damp and it probably had solid walls too. damp wasn't even a issue before the advent of cement plaster and plastic paints
@@hewoguys2506 it wouldn't cause damp cause there's no cavity itself the damp happens on solids walls when modern materials are used like sand and cement gypsum and plastic paints as long as lime is used properly and limewash linseed paints etc shouldn't have any problems damp wasn't really a issue before the advent of standard materials now cause things could dry out naturally with breathable materials
@@jackwardley3626 cavity are made to stop moist on internal wall and this is why solid walls have damp as there dont have one and are permable and yes modern materials are no good for old buildings
When i saw the bitumen paint , i thought well thats probably the problem, not breathable trapping mosture . Great reaction video. Loved it . Ive seen this guy popping up alot on RUclips and seems to be hit and miss with his knowledge. He is after all a plumber by trade ..... maybe he should stick to plumbing videos
That is efflorescence that comes through if it is a solid wall with lime and Cotswold stone and there is a broken downpipe on the outside. There can be degrading of the lime mortar, then the water ingress causes the efflorescence salts to come through on the inside. However, this house has a cavity.
Good vid - so much mis-information out there. Most issues are solvable by careful investigation and removing inappropriate materials. I've yet to see a real example of 'rising damp' in a single video on RUclips. What could be the reason for that...?
@@dampsam Hey. Yeah I get that..apparently rising damp is rare...but I cant even find a single real example...but the term is bandied around like every other person has it...
My house is 200 years old and still have Salt Peter coming up. Must be in the ground. They used to knock the houses down in the old days and use the potassium for explosives. So you kept it secret.
I’m guessing but i think the wet patch where they removed bricks is probably them using water to lower the dust while using an angle grinder to remove the bricks , Also the muppet in the black hoodie is a general builder at best , he made a cladding video and every mistake you can make , and tried to lie about it when i called him out ,
If a surveyor states that there is rising damp ask how they tested for it as the two prongs do not work as they use electric conductivity which paint can bridge
There are standard patterns of readings and along with other clues an experienced surveyor will know. You only need the testing oven test if it needs to be proved outright to an entity. Unfortunately not many surveyors have the qualifications and have done the actual work so this is where the issues come in
I've just come across , rentokil damp proof course , there's a cable in the outside wall, but no obvious signs of a plug , apparently its an osmosis system , any one no if this worked.
It should send an low electrical pulse at time intervals. If the wire gets cut or circuit broken it stops working. The pulse is supposed to alter the shape of the meniscus of the water in the capillary’s but no one knows for certain really if it works
Some builders have more specialised knowledge and experience in certain types of work….they are not all experts in everything. As long as they are honest and say a job is outside their scope, fine. This is why the plasterer is not also a bricky, chippy, sparky and corgi registered installer. Horses for courses you know.
Damp Sam, you're missing the point. This is a cheap solution that anybody can do themselves to eliminate one more possible reason. And the description you were trying to think of when explaining where water goes is ' water travels a path through its least resistance'. It could also be a few reasons why there is damp there, so eliminating one more reason is ticking off a list of what it could be. So well done Roger mate
It might be very revealing if the four or five leading damp specialist's recorded a one and half hour zoom meeting putting their points to each other and let the viewers decide who has the best insight. I'm sure it could be friendly and professional....@skillbuilder
Spot on with what you said about the vents and the wood burner.

Yes I agree but all industries have a rouge element just look at cowboy builders, banking, police etc. you just have to try do your own diligence
Misdiagnosis will always be an issue but there is people doing the correct courses … following the British standards and always trying to improve knowledge … not everyone wakes up everyday trying to rip people off
7:20 actually this is pretty much how the NHS operates in my experience...
Please keep making these, I really enjoy them. I've learned so much!
Will do
top video's
i have had 2 damp couses now both of them failed
i do not think anyone can solve this even damp sam
I’ve been training to become a building surveyor for a few years, I had no idea about the PSA, thank you for highlighting it!
It’s the PCA Property Care Association
Thank you!

"Roger ya dirty bastard!" haha
IT MIGHT HAVE A PHYSICAL DSMP COURSE IN BUT LOOKING AT IT BLOCK PAVING HAS BEEN PUT IN SO COULD BE LEVEL WITH THAT SO WATER JUMPING ACROSS
Love your Cantona shirt. I'm envious 😂

very good video again sam ! how long do the dry rods last for ?
Dry Rod are an amazing product and the best value ever , believe it or not these will work until the house is knocked down.
thanks so much for your advice sam !@@dampsam
The salt taste test 😂😂😂
Sounds like a sales ad for Dryrods.

As Liam would say Jack definitely maybe, because we were not on site it’s a bit of probabilities.
also probably had no cavity which will also cause damp

Efflorescence ?
@@tonyfairey7733 Yes, spell check changed it.🤣

The reason is properties are built with a dpc since around 1919 and not many old buildings have not had some sort of retrofit dpc these days

Damp Sam! That's what we called my little brother cos he kept pissing the bed 😂😂
I only piss the bed during water sports 🏉💦
How can damp proof injection work on stone walls with no regular mortar line?
You drill at the correct spacing to form a continuous line and barrier
Floor to wall junction/ bridging of the dps
5.15 killed me haha

When they were cleaning the cavity’s I think that was a different house but showing an example
I think your right Lee, they should have said something it’s confusing
@dampsam yes they are 2 diferrent properties the one with the cut off brick line is just for an example of the cavity full or mortar an rabbish.
If the fire is over 5kw output you need a vent installed.
Hello Sam,
Would you travel to South Chesterfield area to do a damp survey.
Kind regards
Yes of course but we charge for surveys email dampsam@thedampshow.co.uk for further instructions
If the wall is plastered, tricky to find those joints. Or would you recommend another solution for plastered walls
I don’t understand the question
I've just come across , rentokil damp proof course , there's a cable in the outside wall, but no obvious signs of a plug , apparently its an osmosis system , any one no if this worked.
It should send an low electrical pulse at time intervals. If the wire gets cut or circuit broken it stops working. The pulse is supposed to alter the shape of the meniscus of the water in the capillary’s but no one knows for certain really if it works
It categorically has not worked, biggest load of rubbish out there along with DPC injecting...may as well inject peanut butter.
If an alleged builder calls another builder for a second opinion never use the first builder as clearly they don’t know what they are doing
Good point
Some builders have more specialised knowledge and experience in certain types of work….they are not all experts in everything. As long as they are honest and say a job is outside their scope, fine. This is why the plasterer is not also a bricky, chippy, sparky and corgi registered installer. Horses for courses you know.
Brainstorming

🤦🏻🤷🏻♂️
I see no headers. It’s a cavity wall
All of this is caused by high ground levels...... Buy a shovel!
🫣
I would like to see you plastering mate
No prob, when every your in Barnsley drop me a message or watch one of the many videos iv done just search for Damp Sam Al
