Floor level tolerence

[ml1936]

How level should a floor be over certain meterage?
IE 5mm over 3M etc
Just to determind if floor is level enough

Just to determind if floor is level enough

for what!?

5-7mm humps or hollows are not unusual across a domestic floor.

a slope from one end to another however may indicate settlement or subsidence.

whether a floor that has been laid by a builder is flat enough

whether a floor that has been laid by a builder is flat enough

flat enough to play snooker on or flat enough for a dining table???

 

[ml1936]

Flat enough to put furniture on!
Is there a building reg which states a tolerence???

no.

it is a quality issue.

there is no such thing as a 100% truly flat floor.

and absolutely no hand screeded floor is anywhere near completely flat.

If you find that all the furniture moves to one corner, then it may be poltergeists, not the floor

There is a standard for 'flatness' but unless you've specified it, then it comes down to fitness for purpose, and a domestic floor does not need to be perfectly flat. Its not specified in the b/regs

If you can feel significant dips/humps underfoot then they should be addresses, but otherwise its just a case of 'near enough'

It depends what flooring you want to use.

Carpet does not care too much.

If you want a laminate/timber floor you should have specified a tolerance.

SWMBO wanted a wooden floor in one of our rooms but a 10mm rise into one corner killed that idea. Can't raise the rest 10mm and am not going to start chiselling it off!
