A short clip that explains bridging & penetrating damp on site 

Sam this is the video iv been looking for that's the problem iv got with the gap between the floor boards cheers

You have an INCREDIBLY kind, friendly face. There's something about you I just instinctively trust. God bless you Sir ⭐❤️😀

Hi Simon. From what I can see from your video this house has a dpc and is of cavity wall construction. Therefore, if allowing for drips splashing back up from the first floor pebble dash render it still shouldn't be able to affect the inside. Yet you have taken the plaster off the internal walls. And surely the chimney breast is affected by hygroscopic salts, not rising or penetrating damp

I suppose that the best way to ascertain if, or not, the bay window wall is made from headers, as you suggest, or it was constructed from half bricks with a cavity to aid forming the arc of the bay during construction, is to drill a hole..then all will be revealed. It would be easier to build with half bricks and a cavity, instead of cutting every brick at an angle on each long side to form an arch....as in the case of header built.

Nice one. Would be interested in seeing a video to show how you safely cut around electrical sockets to fit plaster boards. Cheers.

looks like air brick is below ground level on the outside (6:12) which means rain water will run straight through it into the subfloor

Hi mate do you need to install the rods under original dpc

Your videos are too quiet is there a way of making them louder? I have my tablet volume turned up full.

Should there not be a gap anyway between the floorboards and the wall? as you have to factor in the thermal expansion of the floorboards? the when the skirting goes on you just seal that gap with a timber molding and fix to the skirting board? that would allow the expansion of the floorboards to occur freely and also seal the gaps and prevent any cold-spots? would like to be informed if I am wrong. Cheers

This is absolutely crazy. How can you not have noticed the ground level and the air brick where water will be flowing in?! This is how people get ripped off.

Hi Sam, I’ve recently brought a house and had some damp proofing done - when taking off the skirting I’ve noticed the gap where the air brick is but they didn’t mention anything about it - should I do something to make sure it doesn’t effect the new damp course or will putting a cowl on it be enough? Thanks!

Hi Sam. Thanks for what you’re doing! Just a quick one mate. Comparing products of Stormdry and Sovereign which are any better? Thanks

Hi mate, great video, just a question. With the sealant painted on the outside of the wall, does moisture still escape from the cavity ok? Thanks

Hi Sam. I have an single storey external solid wall which was rendered years ago. The render is blown and cracked and seems to be letting penetrating damp through to the interior. I'm not too keen to re-render in case the same things happens. Would it work if the old render was knocked off and the wall was painted with Stormdry masonry cream?

Would adding a vent help? I got the same issue and someone advised adding a vent

What did you use on chimney breast please?

Just been drilling and rodding on outside, i've got two drain pipes in way (not movable) is there anything i can do ? Also i've got an understair electric box with damp behind whats the correct process, box is going to be swopped but not for 3 weeks would like to get the house dry

Simon. You say the cold damp air is coming in from the air brick. Is the ground level too high. Surely if you lower the ground level to below 125 mm the problem will solved at a cost of a few hundred pounds. Labour , removal of rubbish and pea gravel. Also if the building is of the age you say it it would be of a sand lime construction. Bed joints and perps. If you put on your storm dry paint your sealing in any moisture which has got in from the loose cement over pointing. The brickwork will have to loose moisture some how. Surely it will force itself out of the face of the brick or possibly through the mortar joint. Won't your your paint end up on the floor with the loose brick or mortar joint. I think rather than foaming and removing the plaster internally the best option would be to lower the external ground level and stop cold wet air raising the dew point and creating condensation internally.

I have a issue as there's a smell that's horrible but I can see any damp. I have dug up around the front of the house to see if there's moss ect. But nothink it's geting me down tbh I have called a few places and thay just say if there's nothink viable then thay can't help 🤔😔

Crap

Does make me laugh you refer to a British standard BS6576.......what about .....British Standard - BS 5250: Code of practice for controlling condensation in buildings, says; 'Accurate measurements of the moisture content of brick or mortar cannot be obtained by the use of electrical moisture meters because the presence of salts increases the electrical conductance of the water, giving falsely high .readings

Hi can't hear you please speak up louder

Another one who doesn’t fix the route cause but applies unnecessary products to the building bad advice I’m afraid
