damp

I've recently had an issue with damp next to a party wall where we had a unit pushed up to it. We're fairly certain now it was condensation / lack of air movement. Neighbour has no problems on their side. The skirting board was rotten, so I've taken it out and was surprised to find a second...

Hi there I have an outbuilding which I suspect the dud builders had used interior paint on the exterior walls. It’s a double blocked structure with cavity insulation, but I’ve noticed that there has been some damp in the room and humidity is about 77% when I go into the room in the morning...

We've had a problem with damp on this corner of our house, gut feeling it's this brick side-gate post that looks like it would bridge the damp course ... is that likely? We had a damp surveyor round who didn't mention this but I think he just wanted to sell their DPC injection ... he didn't even...

Hope this is the right forum category for this, apologies if not. Long story short... we had a shelving unit pushed up against a wall in the living room of the house, it's been there between one and two years. Moved it away recently and found a damp patch on the carpet around 1.5 ft long by 1...

Hi All. I have got some damp issues that needs to be resolved. Based on the damp report the specialist created and my own understanding also. I am a little confused as to what the way forward is. I am always wary of damp companies and wanting to do unnecessary works. The house is a mid terrace...

I decided to finally deal with some blown plaster around a kitchen window, and ended up removing all of the plaster below one of the windows, which came away easily. Underneath, the brick seemed slightly damp, which is strange given all the hot weather we've had recently. At either ends the wood...

Hi everyone, We noticed a patch of damp last year and didn’t get round to doing anything. Eventually got someone to clean roof gutters. We thought would have solved issue but yesterday the vertical patch looked darker and felt wet despite having no rain for a week or 2 now (unless I’ve only...

Hi Guys, The property in the photo illustrates a plaster-rendered wall with damp appearing to be rising up it. It was plastered about a year or two ago. Initially, I thought it was possibly just the plaster drying out but quite recently it has now started to show some salts in one place, which...

Hi all, considering buying a 30s semi and noticed a couple of dodgy-looking areas on the walls during our viewing. Would really appreciate a second opinion from anyone with a bit of experience in these things. Firstly beneath the bay window in the lounge, there is a large area that looks...

Hi, i have a 1930's house. Started getting a white residue line going across my property wall. I was told that my driveway being butted up against the wall is the reason. So i got a drainage specialist for a quote for aco drain installation. He said you have dpc its the two blue bricks above...

Hello all, I am hoping somebody might be able to help with an ongoing issue we have under our upstairs bay window. The house is a detached 1930s house. We renovated it around 6 years ago now, and this problem only seems to have arisen in the last 3 ish. Under the bay, we have a number of...

Hi there, Any help here would be appreciated. I have recently bought a converted stable, in my living room I have cupboards and a seat against a solid wall (see below). I want to insulate the wall behind the cupboard. The wall behind the cupboards is very damp and makes keeping the...

Hello, I took out the plasterboard and seen some damp on timbers.. what would be the best solution for this? Wall then 3 timbers, single wall. Noticed some damp on the other side

During some renovating I realised our bay window has a water leak. Will remove and reapply the silicone sealant on the external sill (where the sill meets the window frame) to try fix this. Just wondering though, looking at the windows from inside, one of them has some sort of seal/gasket...

Hi, I have two issues with an external wall. One issues is that the pointing in the brickwork below the damp proof course seems to be in a bad state of repair. The other is that there is a damp patch on the wall behind the chimney breasts, and it seems to have an odd "rainbow" shape to it. The...

Hi all, We are getting penetrating rain coming in through our gable wall. The gable is made of block work added for a hip to gable loft extension, with a very thin concrete render over the top. There is some cracking visible as seen in the photo. We are thinking of the following solution: 1...

Hi, I recently laid down a new insulated concrete slab for my new garden room. I have drawn and attached the slab detail. I have noticed a dark damp patch in the corner under the DPC I've laid under the timber frame. There hasn't been much rain and the dampness is a brown-ish colour. Would...

Hi all I have noticed a series of narrow black lines on an interior wall between the bathroom and the bedroom. They are about 30cm long and 1cm apart and only appear in an area about 30cm by 30cm. This area is behind the tap end of the bath but about 50cm above the bath level. There are none...

Hello, I am converting the garden brick shed into a garden office and music room. It is built from brick walls with a concrete floor. I’m planning to building a stud wall and insulate with mineral wool (rockwool). the brick wall is essentially the garden wall, where they have popped a...

In the living room of my son's middle floor tenement flat, damp appeared in the corner of an internal wall, external wall and ceiling. Turned out that upstairs had a rising mains leak which was eventually fixed late 2022. However, both walls about 1m each in from the corner were damaged...
