I have an ensuite bathroom and right next to it the downstairs cloakroom. Both are situated in the middle of the house and ventilation is impossible. I had an idea to go down through concrete floor into a basement but the area (crawl space) is very hard to reach and work in. I am not sure what...

How do plasterers/builders close the reveals on external doors? Tried today to stick a piece of plasterboard on one reveal at the utility room door, it is a cavity wall and we have 100mm block, 100mm cavity with plastic cavity closer over it, and finally the door frame. The cavity closers are...

I have had 3 separate groups of plasterers to work on various areas of my new house and they all complained about how quickly the blockwork sucks in water and is prone to cracking. On the photos you can see how one group of plasterers left the job one afternoon, everything has cracked and in...

I will do just that, full planning for a single storey extension to the back of the house with a lot of glass, even on roof. Not sure about the required U values so will have to do some reading.

I have just asked my building control to let me know what they think. I have also read some very old threads about needing to keep it separate from the house and then you are OK as far as BC is concerned, by means of a door to separate the house from it, which people then remove...

I have been re-building (literally it seems) my house, past 3 years, with a side, front and roof extension. We have always had a large-ish patio which I am thinking of converting to a conservatory. The patio is at the back of the house overlooking the garden and spans almost the full width of...

Thank you, but unfortunately I cannot use that. My house is littered with steel beams and columns, inside the blockwork, inside the floor, above, below, everywhere, and there are hundreds of timbers, joists and plywood floors and timber partition walls notched/attached to the steels. My...

Trying to "box in" steel columns and beams, and make the coverings as small as possible. I insert noggins into the steel beams and then directly fix plasterboard strips onto these noggins. But when I need to cover the flanges of those columns and beams, I was thinking of glueing a...

I have had a few rooms and areas hardwalled and then plastered. All the different plasterers (about 4) applied the hardwall in one pass and then kept going over it to smoothen it out, but 99% of the hardwall material was applied in the first pass, thickness depending on the blockwork which is...

I have had a few rooms hardwalled and then plastered and they have failed to produce straight vertical lines on the inside corners where two perpendicular walls meet (eg the 4 corners of a room). I appreciate it is all done by hand and down to the skill of the individual. Could they have used a...

I have a few areas of vaulted/angled ceilings, with many angles, and the plasterboards are not perfect, and am wondering how to achieve straight lines on inside and outside angles? What sort of metal bead could be used or some other technique? On the photo you can see the straight lines at the...

By "fuse" I mean whatever circuit breaker they use.

Outside each bathroom there is a 1.5mm live supply into a light switch and from there a 1.5mm cable to the lights. The live supply goes straight to the fusebox and has its own fuse. I add another cable from the light switch to the towel rail and another cable to the fan. I also add one more gang...

I have forgotten to allow a dedicated circuit for a towel rail on all bathrooms and as a solution i have hijacked power from the lights circuit. The wiring is 1.5mm to the lights switch. The wiring to the towel rail is also 1.5mm. The towel rails on the market are 250W mostly, some are a bit...

Can i wire a fan on the same circuit as the bathroom lights without an isolator or any other gadgets, so a simple on/off? The feed to the fan is a 2+1 1.5mm same as the lights, but i was told instead i needed a 3+1cable and an isolator switch.

I was thinking as mortar tends to shrink and crack a lot, there are other fillers I could use, hardwall, repair mixes, adhesives, grouts, etc and wanted to see if anyone has experience with something that will work well with those "soft" blocks to close those large holes but also other cracks...

Yes it did bounce terribly with a man weighing just 62kg on it! So I have turned the 4x2 on their narrow edge, but have not tried them with a live load yet. As you said, I do not expect miracles and still expect bouncing, even with noggins and with the coverings on ( a sheet of ply and the...

I have opened some "pigeon" holes into a number of blocks in order to put joists through, about 50 x 100 each. I then changed my mind about the joists (there is another thread) and made more holes higher up. I would like to close up the extra holes (on the photo, the bottom row) and am...

Thanks guys. I have used expanding foam extensively in other situations, but in this case I wanted something more structural to close the gaps. I recently bought a mortar gun (https://www.amazon.co.uk/gp/product/B01AX08IWS), If I mix 1:2 or 1:3 muck and make it runny and try to see how it...

OK, so I need to tape all joints between plasterboards, insulated or not. If some gaps are larger, or there is some small areas of damage, say bashed plasterboard corners, is it better to fill the larger gaps with something or let the gap be and simply tape over it? ************************...
