best way off...

[Spare Tool]

and most cost effective way off bringing a wood floor up an inch??
I have a job to price up going to look at it tomorrow...
45m through three rooms 2 off which are the same level but was told one room is aprox an inch lower. The customer wants the tiles to run through at the same finished level.
Electric UFH and large format porc tiles.
These are all wood floors the lower room is t&g floorboards and other 2 chipboard.
All I can think off is 24mm ply over lower room then hardi over the lot or would just marmox boards surfice, or should it have both?

Are you planning to insulate all 3 floors if so you could fix marmox on the 2 chipboard floors and then build the floorboard floor upto the same level using marmox, they do sizes ranging upto 50mm.

Yes I was planning on insulating the whole floor, that's interesting I didn't know you could get marmox boards that thick, that could be the answer, i'll have a check on the prices and see how it compares to ply.

I'm on a job at the moment where I've had to build parts of the floor up as the sparky only fixed insulation board down where he was fixing the UFH and not the whole floor. So the client going for his cheaper quote for ufh isn't cheaper at all.

...."the tiler will get over that" springs to mind.
What did you use to build the floor up?

I'm putting down 10mm marmox which will hopefully make up the difference. I've had plenty of "the tiler will get over that" lately. Let us know what you decide on and how it goes

Looked at the job last night and as ever all is not quite how the customer told it on the phone...
2 rooms are infact good solid t&g floorboards which then meet up to a concrete extension, not chipboard. After setting up a laser found that the guys that built the extension were a good 30mm down on the point that it meets the t&g floor, but then steadily rises to near as dam it level about 2meters back, so I'm thinking its gonna be rapidest over the join in substrates to seal it off, 5-10 bags of flexi leveller in the dip, 10mm marmox boards over the whole floor, fit ufh, level over ufh, fit 5sqm of crack matt over join in substrates then get some tiles down..
Any constructive comments or see anything wrong with this prep?

Sounds like a typical screed nowadays. Not had a decent new screed for ages. Yeah I would level the dip.
Never used a crack Matt before would normally fit an expansion joint where the two substrates meet. However I know it's not pretty and not ideal when doing brick bond.
I assume the crack Matt does a similar job.
