Whitby Chimney Jenga

By Wendy the Other Half

(All the details for for the chimney rebuilding are here on the main iDoDtuff site)

The second of the top floor double bedrooms will be cosy. We are erecting a stud wall to form a passage to the master bedroom. It will easily fit a double bed but we want to make it as large and airy as possible. With this in mind I had managed to talk the Stuff Doer into removing a lath and plaster wall that had been built in front of the chimney stack, along with the two built in cupboards either side.  Yes we were losing storage but it was much deeper than necessary.I visited after the Stuff Doer had been on one of his lone forays. “Yes” he confirms, the room looks so much bigger now. The only problem is that the lime plaster behind the old lath and plaster wall is a bit crumbly, too crumbly to repair. Ok, no probs, pull it off and re do. The Stuff Doer’s been itching to have a go at a full wall anyhow.

Oh dear! As we removed the plaster some rather curious gaps began to appear in the brick work. By gaps I mean fist sized holes that look like whole bricks are missing and a gap between the stack and the back wall you could slide your hand through! These gaps had been filled by the lime plaster. The chimney stack has actually twisted. Now I know this sounds scary but we know it’s not shifted since the wall in front was built, we can tell by the construction of the wall, hand riven thingies or some such which Stuff Doer will go into in more detail I’m sure.

No, what’s scary is the Stuff Doer’s solution to make sure the stack is stable and moves no further. Hence Chimney Jenga, carefully removing one brick without disturbing its neighbours then reinstating it and pointing in, again without disturbing the other bricks. Using this method he can rebuild the chimney stack piece by piece.

On the bright side we now have an explaination for the “quiant” shape of the stack and by the time he’s done, it will be safe for Father Christmas to visit. Although whether the roof will be safe for the sleigh to land on by then remains to be seen!

Please scroll down to leave any comments, suggestions or responses, we do like hearing from you.

  2. Hi, A test for lime mortar or plaster is to take a sample and drop some vinegar on it. If it fizzes its lime. Cement is also grey in colour whilst lime is a lot lighter (although it may have been coloured so not conclusive).

    Sorry I can’t advise on what render to use, it will all depend on the exact situation. I do know many good lime suppliers offer an advisory service. Check out their websites and give them a call.

    Just for information I used NHL 3.5 (hydraulic lime) with a sharp sand and soft sand + hair on the back of the cottage.

    Hope this helps

  3. Been a bricklayer (mostly reclaimed stuff) for 30 years and I love the angled hawk you made from an old plastering trowel!

    I use a bricklaying trowel and a ‘flick of the wrist’ to load up my own home made finger trowels (made from cut down cheap “Sunday market” pointing trowels) but I’ll definitely have a go at making something with a turn up now.

    It’s a bit laborious I know but I run my sharp sand through 5mm mesh nailed to a frame. I find it gets me a perfect sand to use with lime. I guess it varies region to region too.

    Nice job on the chimney, to nice to be hidden away up there lol!
    Stay well

  4. Hi Ian, Glad you liked the angled hawk, I find it very useful. The sharp sand I’ve been getting is fine enough but I’ve had few bags of soft that have been contaminated with some big stuff, an absolute pain when when I’ve been using it for a finish coat.
