Hi, I am about to build a wall in the living room to extend the door into the hall. I don't want to build a stud I want to build it out of block. Can I just remove the 2-3 inch of screed and the small sheet of polystyrene and then lay the new block work directly on top of the sub floor? I...

Hi, I have read a few threads about tiling on a wooden bathroom floor. I am going to rip up the chipboard in my bathroom put noggins in where needed and then cover with 25 mm WBP PLY. Some threads suggest sealing the underside and edges of the ply before fixing to the joists. Can you advise...

Nice one! Just what I need. Many thanks Hugh....:)

Thanks Hugh, I had looked at that but I have no movement in the pipe at all as I have attempted to move it upwards. I don't know if I would be able to get enough slack on the pipe to insert it into the slip coupling both ends.

Hi, I want to add a toilet in the room next to my current bathroom. I want to leave the original toilet where it is and the other toilet just the other side of the wall. I will need to remove the soil bend that I have and replace with a double. The problem is that the soil stack is connected...

Thanks for the reply. It is an oil fired, Grant Vortex combi 26e. The pipes will run along a bedroom on the second floor about 2.8M and then up to the third floor, across the third floor bedroom about 3M and into the rad. The other rad is a further 3m.

Hi, I am about to extend the heating system up into the loft. I have a combi boiler which can handle the extra rads and the system is running through 10mm micro bore copper pipe. I was going to extend from the 22mm flow and return pipes with further 22mm pipe up to the third floor and then to...

no mine are 100mm rafters so can only get 50mm under. I am going to tac 30 mm onto rafters and go 80mm under and 50 over.

There will also be 25,000mm2 in the eaves. This is sorted with eaves vents already..

The BCO told me that it should be 5mm2 of continuous or similar. The vents are the 'or similar' route..

Hi, I am in the middle of a loft conversion and have to provide 5000mm SQ continuous ventilation. I have seen some suitable vents which give 9,000mm SQ each. I am trying to work out how many I need. The roof space is 8.6 m long. Is my math correct? 8.6 x 5000mmSQ = 45.000 mm SQ. So I...

Hi, I have to fit 50mm celotex between the rafters and 80mm over the top with 12.5 plasterboard over the lot. I am going to use 150mm drywall screws to fix the 80mm celotex and 12.5 plasterboard to the rafters. Is this the normal way to do it?

Can anyone tell me the best way to fix 80mm thick insulation board over the rafters? I have to put 50mm between the rafters which is no problem but to fix 80mm over this would need 150mm drywall screws. Is there anything else out there that would d the job?

find a decent carpenter and he should be able to clad it for you. He should also be able to add some trimming details to make it look even better. I have just completed something similar myself, I copied a picture I found on google images under 'box newels.

Hi, I need to find a radiator for each of the two bedrooms in my loft conversion. One room has one velux windows and measures 35.2M3. The other measures the same but has two velux windows. I have used the BTU calculators on line but thought I would put it passed the experts on this site...

I have been instructed to use 80mm Celotex GA2000 under my rafters (in addition to 50mm) I cannot find GA2000. Is GA 4000 better. Can I use this instead?

No it was not full plans. The span is less than 2.5m so I think C16 is okay. Plus the joists will be doubled up as trimming around the stairs. However non of the spans are greater than 2.7m.
