Hi, I am living in a Mid floor Condo, the affected area is the wall near my 2nd toilet. I am facing some issue where paint started to bubble and in certain areas Mold started to grow, at first i thought it was a water leakage, but when I look at the water bills it seems fine( RM 12- 15) per month. When I touch the walls, it seems very powdery even the steel door frame started to rust a bit from below. FYI There is no pipes in the Left wall.

My WC Drain Pipe connection when I flush some water will splash out from above the connection will that be the problem? But it is kinda a far away from the affected area.

What do you think ?     
What should I do ?     

already paint 2 layers using water proof painting on top the car porch slab. unfortunately, beneath the car porch slab still leakings....2/3 days after raining time. possible water may come from elsewhere??

after new year, i will paint the third layer and hope for miracles. in btw, the waterproof paint brand i used is sikacoat. any comment?

10 layers is what you need...

drain on car porch slab. but I already paint one layer onto it earlier

Want to ask

If renovate toilet. Redo all. Usually do they cover whole toilet with Waterproof. Or just below part

hi, not sure if this is the correct place to ask.

1) im facing leakage of water from the roof of my car porch when i switch on the air-con only, not when raining. How can I solve this?

2) Beside, same car porch, water leaking in between my car porch and awning when raining.

3) water flowing out from the kitchen sink is very very slow. Previously, the plumber said maybe the piping underground got problem hence he used some gas/air to clear the pipe temporary. the condition was solved for few minutes and the issue came back until now. Do I need to rebuild the whole piping?
Can anyone provide me some suggestion? My previous contractor was the worst of all and I have to stop him before burning out my money.

I noticed that there was a leak downstairs from my first floor toilet, i have engaged a few contractors to check and fix and the problem is still not solved. There is no one using the toilet since its a guest room, i only go in to wash the toilet and noticed the leakage.

I have tested to determine if its a tile waterproof or internal piping issue by turning on the stopper (after few weeks of non usage / non cleaning), within a day, there will be leak to the bottom ceiling.

One of the contractor claimed there is a crack in the concrete upon inspection from below, another claimed there is a crack in the drainage hole. A couple of them just don't contact me anymore after inspection despite promising a quotation.

One of the contractor tried waterproofing the floor tiles and still leaking. Another contractor suggested pulling new pipes from the ceiling (no hacking of tiles).

Appreciate any thoughts on this matter, if its a truly internal piping issue or other possibility.

House (and toilet) is newly renovated for about three years.

This is regarding a new house.

The bathrooms have a shower area that has slightly lower floor area and come with shower screen. The floor of non shower area (toilet bowl and sink) is slightly higher.

I pond test the entire bathrooms (two bathrooms with same design 8-3' x 6-3'). The shower area doesn't leak below. The non-shower area leaks below (I come back after 24 hours).

Is this normal? Or is this consider a defect that need to be rectified by developer? I need to ask because as expected, my developer argue that no body flood the non shower area in normal use and I have also void the warranty.

Thanks in advance!

The developer claims the bathrooms are fully waterproofed.

If let's say a large bathroom (master bathroom) is not fully waterproofed, do you mean they only waterproof 'half' of the non-shower area near the drain?

Clean the edges and inject clear silicone. Then use a flat ice cream stick to press the silicone to cover as much gap possible. Do it on hot day.

If dont work, have to call contractor. He will have to remove the window and inject silicone on the outer frame. My landed house, I inject outside and no more leak.

Hi all - those living in older apt or condo, what is your experience with bathroom having bath tubs? How likely is it for bathrooms with old bath tubs to 'store' water underneath it and start leaking to the unit below? Is it recommended to just remove that old bath tub if it is not in use anymore?

Also, in terms of waterproofing have you come across contractors who previously did not fully do hacking job for the waterproof. Instead, the fella removed the old bathroom tiles, then coated a layer of waterproof paint and then lay with a new set of tiles. In this case, I assume that the waterproofing may not be long lasting?

An update on my case is MO suspected one of the building pipes passing through my unit may be the cause of the leak. Repair is underway.

Now, as far as my bathroom is concerned, should I be proactive and just redo the waterproofing properly. Or wait until downstairs file a leak complaint? And yes, I am aware that being proactive in this case comes with added cost and time; but I'd like to see what your views are. Thanks!

Hi everyone, recently purchased an old new house - around 10 years old. I am thinking should I check for any water pipe leak before I do renovations. Is it a standard practise? I don’t plan to renovate all bathrooms (5 bathrooms!) hence cannot change the piping. Anyone had any experience dealing with water leak detection? Done a pressure test myself, seems ok but not able to test the pipes coming from reserve tank. In Penang, anyone had dealt with any water leak checking company here? A bit worried there’s a leak after I’ve done renovations.

Anyone know if this is reasonable.
