In my loft I have the chimney stack from first floor ceiling to first floor. The neighbors have completely removed all their stack. I would like to remove what's left in ours. I'm also in the process of wanting to put larger joists 9x2 in the loft that will span 4m. These will be sat on 45mm...

What are the typical spacings of the coach bolts used for flitch beams? The timber is 75x145 with steel measuring 10x140 I was looking at a friend's report which says to use M12 bolts staggered 36mm off center line but further down the report it says must be 48mm from ends and edges of the...

One of the bath taps broke so just had to buy a new set. After finally removing the old tap which was a struggle, I noticed the bath tap had some sort of clay type compound all over the thread and inside the square indent in the ceramic bath. I'm guessing the square indents were to stop taps...

I'm want to put bigger joists in the loft. These will be independent from the ones already in place. I have a question which I'm sure someone will be able to help with. Where the bedroom door is is a timber frame which I believe would not be suitable to hold the weight of a floor so I think I...

I'm planning on dot and dabbing 12.5 plasterboard to brick wall but the door frame doesn't stick out much and the brickwork varies in places near the door frame. What I'm thinking of using is some strip wood and sticking it to the door frame, is that acceptable? What I'm not sure of is where...

Do the pad stones off the shelf at the merchants meet c30p? I'm going to guess they do but I just want to check in case the SE as just specified something out of the ordinary. And am I correct I should use 1:3 mix for bedding pad stones. 1 cement / 3 building sand that is. Thanks

So after looking at the steel beam my SE as specified, I have noticed the depth between the flanges on steel beam is smaller than the actual joists on the 1st floor. The joists are 175mm and the beam which was specified is 178mm however the beam only as 146mm between the flanges so you can't...

I've got 3 timber lintels that need 10mm steel plates bolting to them. 2 of them seem straightforward as they are not built into the cavity. However the front bedroom one which is 3m long sits below the ceiling with the rafters resting on it to the bay window. Now one end is built into the party...

I want to put a stronger floor in the loft. At the moment the joists in the loft are only 75x50 with the joints running from front to back of the property. Now I have had a structural engineer around and he said he would have to calculate the new floor as a proper floor because of the spans...

I'm having trouble with one wall that's traditional plastered, I have given it a mist coat of white contract emulsion 50/50 but I'm seeing what looks like hairline cracks that run diagonal in various spots If I run my finger over them I can feel the paint where it's raised, the paint doesn't...

I have a property which has step cracking going up the rear side of the house above the first floor, the cracking varies in size over an area of 2m in length to 1.5 in hight, we had a structural engineer look at it and he has said it looks like it was caused when the house was extended. Is it...

I'm looking to plasterboard my external wall in the front room with Spacetherm Aerogel, however the window reveal is very uneven with bricks poorly chopped in half and sticking proud of the internal leaf, the cavity is pretty poor around the window as well so I can't use insulated cavity closers...

Is it common to find ceiling joists resting on wood packers ? the wood is 21mm thick and as shrunk in parts from the weight of the joists, not sure what type of wood it is, one of the joists is sitting on a piece of wood that covers about half its width. It looks like the builders never...
