Wood Floor Bulging

yaz2010

Hi members,
I noticed something yesterday which has freaked me and the mrs out.
We moved into a new house 2 months ago. Living room has wood flooring and we installed a new wooden laminated flooring in another room. For the last 2 weeks central heating is used during morning and evenings. I just noticed yesterday a bulge on one side of my few floor. And today I noticed another bulge on the flooring which already existed in the house.
Is this normal? What can I do to fix it.

I have called the builder who installed the new floor to come and take a look at it but he wont make it before Thursday.

Any comments on this would highly appreciated.

Thank you.

Not enough expansion gap at the edge of the floor. Moisture and temperature will cause the floor to expand and thus press up against wall.

Is the floor under the skirt or has edge beading been used? either way that would need to come up. then use a Multi tool (oscilating) around the edges to create a slightly bigger gap

Good luck:)

That would be my guess too.

Is it wood or laminate that's bulged?

Wood floor has bulged around the centre about 50 cm.

Laminated floor has a bulge of about 20 cm, not so much in the centre of the room. But it is not near the corners.

Where the bulge is, is irrelevant, it's just where the expansion (pushing from the sides) has manifested.

The only other thing it could be would be moisture / heat from below which is distorting the laminate / wood. Harder to fix as the whole floor would need to come up to inspect the subfloor.

Just wondering what could have caused it. It was fine for 2 months. Is it because of central heating ?

you have a leak some where - I had exactly this issue - case of taking flooring up for it to dry out and locating and fixing leak.

Could but, if it's leaking. As already said the most probable cause is a leak, how were the floors laid? What's the sub floor concrete or wood? If there's a polythene membrane under the laminate the leak could be anywhere.

Polythene Membrane (Underlay) was put in before the laminate.

As far as the wood floor is concerned , i think there is concrete underneath it.

@lemontart : did you have to take the whole floor out to fix it?

An explanation was given early in the thread. There is only 2 things that will distort wood or laminate and that is temperature and moisture. And my guess is still not enough expansion.

Especially if you are sure water is not coming from below.

Unless you've got quick fit, click together laminate and wood it's all coming up if there's a moisture problem.

Is the wood floor floating? Not glued down.

You might get away with cutting the skirting if a moulding was used but the floor may split when you flatten it.
