Sorry about no pics - should be sorted now.

Just a quick thanks to those on here that gave me advice on how to do my insurance quote on this job.

My quote was accepted and will be starting the work on Monday - Will post some pics as the job progresses.

Insurance co's can refuse to pay out if the problem has arisen to poor workmanship, or due to poor maintenance.

The few claims I've been involved with have all gone fine, but a QS friend of mine has mentioned claimes being only partly settled if the insurance co's surveyor considers it to be partly caused be poor workmanship or lack or maintenance.

Evenng all - Latest update.


In shower the left hand & right hand walls are plastered blockwork, absolutely soaking. On backwall it's plasterboard, well it used to be plasterboard. Bloody silverfish everywhere. This has now turned into an insurance claim.


Good luck mate, your gonna need it.:8:

That'll keep you busy Taz..just done a quote for an insurance job..the previous owner (supposedly a builder) had used plasterboard under the bath legs to raise the bath height..he also forgot to fully connect up the overflow pipe at either end..he also used MDF for the tiled bath panel :mad2:..

When client used bath, water seeped out under bath and through ceiling downstairs, no access panel so client had to smash his way through bath panel to find out what what was going wrong under bath.. ensuing water damage to plywood, floorboarding, split/lifted floor tiles, plasterboard under bath legs rotted and bath dropped, MDF bath panel swelled up and blown tiles.

Floor and wall tiles no longer available so a complete rip out and refit!:furious3: Nice job if I get it

Good luck there pal. For me i would be showing them exactly what they got under them tiles. At least so they can think about ripping them off!!!

looks like the old guys already ripped 'em off!!

Just looked at the photos, don't British Standards require that area to be tanked?.

As yet British standards dont stipulate a need for tanking systems ( i think) i also believe we are lacking behind the rest of europe in that area.
I believe SWE has made a few posts on that subject.

Indeed I have. In an average bathroom over here, roughly half of the materials cost (not counting tiles) goes towards waterproofing. All the walls and the entire floor has to be waterproofed, for starters. The rules are quite strict on what systems you can use in any given situation.

Here are a couple of pdf's displaying a couple of waterproofing systems. They're in swedish, but there are pictures.

We can't use any wood based materials in the substrate at all. Regular plasterboards have been banned in bathrooms, so we have to use fiberglassfaced plasterboards, or fibercementboards, unless the substrate is massive concrete or brick. Every bathroom is treated as a wetroom. As far as I know, the rules are about as strict in the rest of the nordic countries.

All tiled showers require tanking up to 1800mm minimum in NZ, 300mm up above baths etc, but the standards are not as high as Australia where I understand the whole bathroom is supposed to be waterproofed and drains provided in the floor (to deal with flood/overflow situations).

Obviously (from Swe's post) Europe is pretty strict about tanking too. Being that I run across a lot of water damaged untanked bathrooms, it just seems odd that the UK and the US are so far behind on this issue.

Hi all again - latest pics on this insurance job

After removing the shower tray I found that previous guy had used blockboard rathe than 3/4 ply - totally soaked and tore like paper. After removing the plasterboard off the wall oposite the shower door, I found only three noggins in stud wall. Spent a fair bit of time adding more at 300mm centres. You can see which ones are the original ones as they are slightly darker than the rest. Skimmed the other two walls today. Going back on Tuesday to check on plaster and hopefully start the tanking. Will post more pics as and when.

hi taz,
what are dimensions of stud joists, they look like 2 x 2's, if so I'd be inclined to anchor bolt them to wall behind, (had a bit of a 'mare myself this week with bouncy (metal) stud walls. Good luck mate

They are 4 x 2 PAR and all secured with 3" No 10 wood screws. It's just the angle of the pic that make the noggins look rather weedy. This is just a partition wall with plasterboard on the other side - if you look closely you can see 4 anchor bolts at the bottom of one of the pics. These are for a radiator on the other side.

oh yes!
