Waterproof cost for bathroom leaking

The bathroom leaking causes the basement wet. It seems that I have to remove all the tiles to do waterproof. I am wondering if I should call a tiler or waterproof specialist for cost-effectiveness.

Is there any way to do waterproof without removing tiles?

 

First investigate the exact location of the leak.
If it is in the piping, under the bath or shower, or under the tiles, waterproofing over the top won’t help.

 

There are companies that will do this for $400-500 BUT in my experience they are not a long term solution. You need to do it properly. Locate the source of the problem as @Marg4000 posted and then take appropriate action.

 

Not usually but sometimes. Many times water leaks will damage wall and flooring timbers and need new timbers as well as cement sheeting prior to waterproofing which is a plumbing trade. I have a client in Melbourne that specialises in this work. They have rapidly expanded due to excellent work and reasonable pricing.

Yes ...might be the neighbour's cat sneaking inside and doing a little puddle in your basement

 

I had this issue and paid someone around $500 to change the existing (pervious) grout for an (impervious) epoxy grout. Im not sure how he did it exactly as I didnt watch, but 4 years late the leak is still repaired.

 

Apply membrane over the tiles then lay new tiles over the top again. You will also need to adjust all of the doors, tap fittings etc.

 

Anyone able to recommend someone in Perth? I need a bathroom re grouted.

 

Sorry for hijacking the topic, but another person here with a small leak from the shower.
Who would be best to get to investigate the cause of the leak? Or is there a way to work it out myself?

I had the whole bathroom redone last year, new waterproofing and everything. Seem to have a small leak coming from the shower under in the crawlspace still, much smaller than original leak before the bathroom was redone, but still a leak!. Could it be leaky piping? Or dodgy tile/grout job?

 

@Kasi - Contact the guys who did your bathroom in the first instance.

 

Interesting. Perth - I just had an assessment from a builder through insurance. (Not covered) They quoted $3000 of work to remove tiles, replace waterproofing. $1000 in repairs for wood, plaster, etc . It was just repaired a couple of years ago for a broken pipe under the shower bath. It wasn’t moisture tested before they started the repairs . Always a hard one to pinpoint problems. Insurance company is forcing me to show evidence of repairs when completed.
