Capping off an old flue?


Big apologies for the lack of technical language and know-how here, but can anyone advise on what could be best in the coming scenario....?

The old pre-cast class two flue was sealed off at the gas fire end about five years ago, after the gas fire was removed and the gas supply disabled by a heating engineer.

I'm sure there should have been some sort of vent or air-brick at the bottom end but there isn't. It's been bricked up and plastered over.

The top end is some sort of ridge-tile, where a tile sits over the (looks shallow) flue opening and it vents to the sides. That's the only way I can describe it.

I'm not sure what's best to do.

Option one seems to be to get the top of the flue sealed up properly (however that's done properly - needs to have ventilation??), or remove the part of the flue which runs through the loft and into the roof, and get a new ridge tile put in. Whichever is best.

Option two is to reconnect the gas fire. But I don't really need one - just considering it as I don't think the flue can be left as is, so might be better to put it back into use?

I'm guessing the flue needs to be cleaned whichever option I go with. Pretty sure it wasn't when it was first sealed off at the bottom end.

I guess there's no way of cleaning it without opening up the brickwork in the house where it was sealed off?

After all that, I guess my questions are whether there's a usual route to getting the flue capped off properly, given it's been out of use for a while, and how much this sort of job is likely to cost in the Cambridgeshire area?

Many thanks if you can help.

Does my chimney need sweeping if I am having a new flue installed for my wood burner?

I have purchased an old house. It has a wood burner but requires a new flue. My home insurance has stated that I need to have my chimney swept once a year but my builder has told me that, as he is installing a new flue, it will not be required this year. I cannot argue what I don't understand so would appreciate some guidance on this subject

I've a mid terrace house and a water patch is appearing on my landing wall which is in line with my neighbours chimney.

I've checked the loft and their stack which forms the particition between our houses is also wet, rain water. They had the chimney breast in their ground floor living room removed. Is the chimney stable? I suspect the rain water is now finding a run off point into my landing wall and loft. What can I do to protect or fix my property, if they are not prepared to fix the problem? I've asked them twice already with no response. Thanks

Is there another way other than re-instating the chimney breast?

how much does it cost to reinstate a ground floor Chimney breast? We have a property which had the chimney breast taken out from the ground floor (in the lounge). We want to be able to put a gas fire or a log fire into our lounge. The lounge backs onto the hall way. We still have the chimney and part of the chimney breast on the first floor.
The lounge is 6m x 3.5m so I reckon the chimney stack needs to be 1m (or 1.5m) x 400-450cm. with just a standard height ceiling. Our house was built in the 1950s.
Is there any alternative other than to rebuilding the breast? and What do we have to do to prep the chimney to take a log burner?
Many thanks in advance.

REMOVAL -Chimney Breasts and Stack

I intend to remove chimney stack, all four breasts ( on a party wall). Would I require a Structual Enginer Report? Would I need to inform the council (Bristol)? Many thanks

Fireplace only has one opening and travels up through house - Confused!

I have the open fire on the ground floor. I use it sometimes with coal etc . I assumed that there would be an opening in the room above in the bedroom. Well I don’t and there is no hearth (and does not look like there ever was one) and it all looks original.

In the ajoining room that backs on to this room there is a hearth only with a hole in the wall (it doesn’t have a chimney breast but a metal plate going through the wall to a ceramic pipe that seems to go up to the roof and down to the kitchen. In total I have 2 chimney pots outside - One for the fire (ground floor) and whatever was connected in the upstairs back room I think. So openings jump sides by elevation with a separate pot . House built in 1929 and not sure if this was accepted architectural design at that time?

My assumption was I would need to put in a air brick in that front 1st floor room but it seems to be just a continuation of the same chimney from ground floor . Want to resist opening it up as I would lose that fire due to the airbrick and possible exhaust gas leakage.

My question is - How common is it to have just a chimney passing a room and having no opening? (I am told fires wont share the same pot on a chimney). That front bedroom just has a chimney breast and no opening !

Do I need a Gas Safe certificate for my installed Gas Fireplace by a Gas Safe engineer?

I got a Gas Safe engineer to install my Fireplace but I am refused to pay him until he provides me with the Gas Safe certificate. When we received the fireplace it said in the instructions that we needed this to get the 5 years warranty. This has been going on for a whole year know and the engineer is refusing to provide us with one. I was just wondering if I need one or not as he is getting aggressive now? Thank you.
