Dips in floor

[mobily]

Hi all

I have just moved in to an upside down property. The living room has a few areas where there are noticeable dips in the flooring. There are also other less noticeable dips in the hallway at the top of the stairs. I haven't yet managed to pull back the carpet for a detailed look, however I am concerned as to what to expect and the potential cost of rectifying the issue.

The property was built circa. 1979.

Many thanks

Are these dips causing a problem?

I've been in many houses with dips in the floor, but it's hardly like puddles will form in them is it.

There are 2 dips in the living room that I would say do need repairing. When you stand on them the floor dips down and can be a tripping hazard.

I'm going to pull the carpet back for an inspection in the next couple of days. I am hoping it just needs some replacement chipboard.

Has someone been cutting holes in the floor, to route cables and so on?
All should be revealed with the carpets back.
Certainly there shouldn't be any structural issues!

I pulled up the carpet last night and the flooring is made up of chipboard. It would appear that the chipboard has weakened leading to dips in certain areas.

I am guessing it will be a fairly simple job of removing the damaged chipboard and replacing with new chipboard?

Many thanks

Looks like someone has cut the tongues of the chipboard to gain access and not put battens under to support the joint.

I know of two bungalows which were built in 1973 and 1975. The chipboard was not of the P5 variety and has suffered badly. it has gone all "crispy" almost as though the glue has evaporated. It dips between joists and really should be ALL replaced before some one goes through it. Just a cheery note!

Hi maltaron

What would the tongues of the chipboard mean and battens to support the joint. I am hoping it should be a simple remove and replace job.

Thanks for your help.

Frank - Thanks!!

Flooring Chipboard is tongued and grooved at the joints. The only way to lift a board to gain access underneath is to cut the tongue with a hand saw or floorboard saw. When the board is replaced it is normal to fix a batten under the long edge of the board that has not been moved to support the joint.
