Wet patches internally on upstairs & downstairs chimney breast

Hello - I have round damp patches on chimney breast in bedroom - under coving to right hand side and on the short return wall. Same place/shape each time we get heavy rain. Airbrick in skirting board. Room directly under has very large round wet patches with many long drip stains in middle of chimney breast and some patch/long drip stain from coving height on short return wall too (right hand side). These patches 'shine' in the wallpaper, even when, apparently, not wet. Fireplace tiled up, with two ventilation holes drilled in middle of tiles. Other half of house using other half of this flue has no damp at all even though identical tiled up ground floor fireplace. Upstairs room has fake fireplace, but gaps around this - ventilation. Chimney pots are capped with clay cowls that have rows of ventilation holes going all round. These sit inside the chimney pot. When lifted out there are wet drip stains going down the chimney - presumably rain is getting in through the small gap between cowl and chimney. Could such small amounts of rain be causing significant wet patches further down? No evidence of damp in loft chimney brickwork. Pointing on chimney seems ok.

Would be grateful for any advice - thank you.

Want to remove chimney breast in sitting room (no chimney breast in room above sitting room)

Hi, we are currently buying a house that has a lounge and a sitting room - we want to knock down the adjoining wall to create one space but the sitting room has a gas fire in a fireplace in the chimney breast. The house has a chimney stack that runs up the side of the house but whats odd is that there is no chimney breast in the upstairs bedroom directly above the sitting room - does this mean its already been removed or is the chimney stack in the sitting room false? I'm imagining if we take it down we'll be left with a cavity that goes into the stack is that right? Obviously we'll get professionals in but wanted some idea as we aren't able to go into the house and have nose!

The house was built in 1999.


concrete lintel in fireplace - does it have to be high temperature resisting?

Hi, I'm opening up a plastered over fireplace and the previous owners have used a concrete lintel as they never intended to use it as a fire. my question is will an ordinary off the shelf (wickes or b and q) concrete lintel do or does it have to be a specifically made high temperature resisting concrete lintel.

I know there are fireplace lintels with a chamfered edge for better venting but I'm fitting a woodburner.

Also, they have plastered right into the fireplace, does this need removing right back to the existing brickwork?

Any help would be greatly appreciated


Wood/coal burning stove in chimney breast

I would like to have a burning wood/coal stove installed in the chimney breast. What do have to do in order to have the job done?

Electric fireplace suite and ventilation

Hi ive bought a 1930's ex council house which has had the old gas fire removed and there is just a big hole.

Ive decided to fit an electric fire suite in its place so it will cover up the hole and create a surround as well, and from reading up i know there needs to be a vent by the chimney breast but im abit unsure where to put one, as once the electric fire is in place there is no hole, and i assume people dont mean to block up the chimney breast behind the fire and then use an air brick in that stack, as there need to be a recess for the fire?

Looking at the chimney breast it may be possible to vent into the floor as i know the room is suspended, or maybe i could add an air brick above the fire with a grill but i think that would look stupid and really it needs to be lower down.

Any help is appreciated thanks!

Can i remove the chimney breast all the way up to the roof in a victorian terrace house

i live in a terrace house, a few years ago i had my chimney breast removed in the front room, and the bedroom above that, the builders put on hangers in the loft to hold it up.

im now deciding on a loft conversion so want to get rid of the chimney completely in the loft as well.

so is it okay to remove the hanger and break the chimney completely from the outside as well, only my half?

and doing this will it affect the neighbours chimney as they usually be joined?

any advice and help would be really appreciated

Thank you

Shared Chimney stack, breast removed decades ago, unsure of any support - Help!

I would like advice upon how to proceed regarding a shared (unused) chimney that has already had the breast removed in the room beneath.

The house belongs to an elderly family member whose late husband dealt with this over 40 years earlier.

She is unsure of what if any support is in place and now the chimney is leaking and needs repair. To add to the issue, this part of the loft seems in-accessible, so no-one can see the remaining part of the chimney.

There is a significant chance there is no support, apart from next door, but I am eager to rectify this but want to do this to current regulations without directly troubling the current neighbour. (simply removing the chimney doesn't seem to be an option).

I am a little frustrated about not knowing the best way to proceed and the dis-interest shown by local builders in wanting to deal with the issue. One of more communicative ones indicated that it was awkward job, not as profitable to tackle as opposed to the ample extension work in the surrounding area. I don't think having the house occupied by the elderly person helped matters.

I have worked out that an opening would be needed in the room below to examine the area. The someone would need plan supports acceptable to local building control. Then someone would need to action this as well as sorting the other issues on the chimney. Either of these people (or both) would then need to be sure Building Control Inspects and is happy so we get a certificate to approve the work.

My hope was to find someone (a builder) to do this for us, but I have failed to get anyone to take interest.

How should I approach this to actually find someone competent in the Manchester area to take this on?

Am I being unrealistic in hoping to find someone to deal with all the steps or must I break them up?

Would convincing my relative to make an opening in the ceiling below first and getting a structural engineer to examine fully and work out the supports needed separately really increase the chance of someone willing to action the work?

I would like to avoid doing it this way for many reasons but I am running out of options and just want this sorted in the coming months, so more beneficial works for the relative can be begun.

Apologies for the detail, but it has been a little frustrating. I would be grateful for any useful advice.


Blocking chimney permanently to stop wind (and noise) coming down the chimney


We don't use our chimney at all, well not for any fires or such as we don't have any.

Problem we have is where we live on a hill it is very windy and the noise coming down the chimney is horrible at times, is there any safe way of blocking the chimney permanently to totally stop the noise



Sorry meant to say tried the bin bag trick, doesn't make much difference which is why I'm looking for perm blocking, thanks
