Hi all renovation experts...

i have a problem...there seems to be a leakage somewhere and cause water bubbles appearing at the wall in my home...
until today, i have no idea where is the source of leakage...

anyone knows if there's any good solution to find the source? besides slowly hacking the wall?

thanks.

failed or not using waterproofing for slab area possibility leakage problem..

need to find the root cause fast, if the fungus grows alot, it will be hard to find. Usually it may due to water pressure to high and leak happens on the joints which are only glued. try to look at the top of the fungus area, it grows after the leakage. But it needs to hack the wall to fix this, no other solution i know of.

i agree you need to fix it. options that i can see:

1) hack open and follow piping until leak is found

2) terminate piping system (clear of water) and install new piping system.

if you want to get rid of glued connections on PVC piping you can explore the clamp system from buteline.com.my (got PE and PB piping with it). the clamp system is fantastic if its closed its closed for good. PB is also very very flexible - less headache i reckon. got it for the entire house (hot&cold water) and very happy with it.

I just fixed my water leaking problem from my house. Its a painful process.....
Just one advice, get the expert to do it. I was initially recommeded to get lousy vendor, end up he hack all over my house to find the source of leaking.

There may be few reason to happen, 1st, if th wall facing outsite, may be raining time only feeling wet. If the wall are facing toilet, then may be your toilet waterproofing system no good, If your house is condo, then may be leaking on the floor of toilet unit above will make your wall wet as well. and another posibility is leaking on your water piping.

Diff case have diff solution. advice you to ask contractor to see in the house, find out the problem, then u only can get a perfect solution on that.

if concrete roof of kitchen extension leak when heavy rain, can it be fixed without demolish/rebuild it ?

thanks

how u want to hack and find the wall since u dont have the pipping layout of the house...

if u stay in landed, what i did to mine
i make a new piping direct from main source to the tank

the freaking problem here is my house just renovated... very geram after re-do piping still can have minor leaks...sigh...

which area?

problem is i dunno which area....
but the pillar inside my house below the bathroom is leaking water lor...

My house got similar problem as well. Have to change the tiles of your toilet floor and redo water proofing for the floor

I suspect it is coming from the burst piping... Cause when i off the main watee supply the leak stops...

Anyway... Just asking.... Is it possible for leak at ground floor and then the pressure push the water up to the pillar as high as 7ft?

Added on March 19, 2011, 12:12 pmall...found the source of leakage...it's a pinhole on the pipe and causing the water to pancut out in small volume....

it's not at the pipe joint area....

but along the straight line of the pipe....probably this is a defect from manufacturer and we fail to detect it when installing the pipe....sheesh....

Replying to an old post.

can you advise me how to determine a good contractor to repair leaking, does he have special equipment / technique not to hack all walls ?

any contact no ?

Thanks !!!

I'm sorry to hear from your bad experience.

This is why I always have water pipes and electric wires not concealed inside the walls and floors.

I have a "flood" in my house due to incoming water from outside which was leaking. Upon seeing that, I have the water pipes to be seen from outside into inside of my house. For some, it's not looking nice and neat. But for maintenance wise, I rather stick with this kind of design rather than concealed.

My advise for you is to whack them off and place them outside where you can see. Although you might have renovated and now this kind of issue arise, you have no other options though.

Bare in mind that there will be other threats like termites if your house door frame or any woods get in contact to those waters. That will cost you even more then.

Sometimes I think it is down to luck also... water movement is a bit hard to predict and sometimes the spot water leaking may not be the exact source as it can flow from other place... in fact I have a friend with this issue and finally found out the leak comes from neighbour unit !

Try to get your original contractor as he will be familiar with the piping layout but else I think any contractor with good reputation should be fine... sometimes you need patience to hack the wall in different area to find the source of leak !

Bro... Leaking under bathroom?
Try buy 'ubat bocor' at any hardware store... Its temporary solution... Can tahan 5-6 month...

Worse advice ever..

Just bring in a plumber and ask him what is the problem..

Edit * Seriously you need an expert opinion and you can't get that from a forumer who doesn't visit the site..

Do you know that all services contractors normally test their work?

For water a standing 1-2 hour water pressure test is done after the job is complete to make sure there are no leaks..

Live and learn i guess..

yes... i know..

this defect only happens a few years after the renovation...the piping has a pinhole defect causing the issue...

Hi,
wow.....it has been a long time that i had forgotten about this issue. even i had sold off that particular property.
Frankly, i had lost the plumber's contact.
Nevertheless, a good contractor will ensure the leaking part is full sealed then only cover back the wall or flooring tiles.
Usually they will do pressure test 1st and will request the property piping layout diagram before start hacking.

can apply to condo ?

Sifuss, any ideals of what's wrong with the wall?

Scrap off the paint and see underneath..

I suspect water damage or a wall crack due to the building settlement.. Happens to all of us..

There's obviously something under the paint and if you won't remove the paint you can't know for sure..

Just wondering whether any water proofing has been done else the it won't leak so easily

Not that easy if its an old house..

It could be due to house settlement/movement and the pipe joint cracked.. It easily be from a water supply pressure pipe or a drain/rain water (no pressure) pipe.. Its a normal complain for some old houses but it must be addressed correctly..

You need to find out the cause 1st.. Then get proper advice..

This is an 10 years old condo... Next room is bath room. I think I'll ask contractor to scrap off the paint and find out the source... Could be from upstairs or my my toilet. Just checking around if you have similar experience??

some walls need to be hacked and re-erect new brick walls because inside is too moist. if the issue prolong for a few years definitely there will be no cure.

solution to this is hack and rebuilt. don't waste money on waterproofing products.

some old house more than 30 yrs, 40 yrs are not worth doing major renovation. better to sell it off and purchase a new house.

Wah.... so extreme? Still can fix bro.... all you need is a good contractor and some patience...

Cannot fix cos myself experience a few walls in different projects before.

All brick wall are porous will dry out in time..

Permanent moisture comes from a source..

Waterproofing a bathroom wall is just general maintenance you need to have it done sooner or later..

If the water travels to another location then repair it at the source and the problem goes away..

You are entitled for your opinion..

If only small section of wet wall in a very large house which is generally dry, selling it and purchase a new one does not make financial sense, repair that section makes more sense..

i have the same issue here, the owner have do toilet and redo exposed piping, but still leaking.

Was thinking any specialist here to recommend to find out the source ?

must apply at bathroom tile... your case i think at your upper bathroom house... not ur bathroom...

Was quoted rm400/point to fix water leakage into wall and room ceiling, is this reasonable price? They also provide warranty if leakage comes back again, foc repair.

If included repaint cost back to normal... then reasonable.....

No repaint
Thinkk i will diy, was advised to put on sealer first then paint back, correct?

Not sure on sealer part... me not expert on this... haha...

They might be help water leakage problem.
Js star construction services in facebook page.
They are water leakage specialist.

Have a water leakage problem with a wall shared with a neighbour in a landed double-storey link property .


Houses in the row are 20 years old and have air wells originally, exposing the space to the rain and heat.


I have covered mine up and made it an extended part of the dining area. But noticed the wall was leaking.....damp after a rainfall. Plaster ceiling was partly spoiled by the leakage.

My new water pipes in the wall were not leaking. My contractor traced it to my neighbours's airwell which is uncovered.....so when rain comes and pools on his side of the wall, it seeps into my side and travels upwards.


Contractor has done his best to go over to their side of the wall, clear the drainage hole and try to "waterproof" and seal cracks as much as possible, saying if it works, it may only last 2-3 years.....I need a permanent solution otherwise my paintwork and plaster ceiling will be spoiled again with dark spots indicating fungal growth.


Will be calling up waterproof specialist JS Star Construction for advice. BTW, has anyone use this JS Star before (apparently named after business owner Jacob Soon), and how is his work? Another company I was referred to was GreenSeal (https://www.greenseal.com.my/). Anyone with experience with both companies, pls share your experience before I hired anyone of them to do the job.

Yes. By using our Waterproof 350A Cementitious moisture stopper and an top coat can solve your problem for 2 years product warranty.
It's very easy to apply. You may DIY yourself on top of the flat concrete roof using normal trowel.


We also have a product called BM Waterproof DF which is easy to use. Self levelling. Just pour on top of tiles then done.
It's transparent. Antislip version and coloured version can be done.
If want to safe cost then apply at groove lines only and 90 degree joint between floor and wall.
Same product warranty for 2 years.

We do have a product named BM Moisture Barrier, you may apply on concrete slab directly after scrapping off old paint.

It is transparent and you may apply your enamel paint on top of it.
But please make sure it is not caused by pipe burst.

one question here, i accidentally drilled into a pipe (in toilet) on a tiled wall, is there anyway to fix the broken pipe without removing / hacking off the whole wall?

For this case better change the whole section of affected pipe for your peace of mind

alright...

Hi Momo Sang

I’m came across your post here quite sometimes in year 2011, and it is possible to share me how you solve the water leaking at wall and the good contractor whom can detect the problem

My house wall is sharing with my neighbor got water leaking issues and is painful don’t know how to check the root cause of the problem

Thanks

Hi Spree,

Came across your post herewith,as I’m also facing the same problem water leaking inside wall and couldn’t identify the root caused problem

Would you mind to share with me how you finally overcome this and any expert contractor you can recommend to me .
Thanks

is there any identified spot where it leak? or water bill very high (abnormal) and nobody has wet walls/bubbling paint?

Water leaking is a very difficult thing to find the source, especially when the leaks is on the underground conceal pipes.
Usually leaks come from the joining. But in order to find the leak source, hacking all the floor tiles where the conceal pipes are laid. Or if you can't hack the tiles, the other option is to bypass the entire conceal pipes and re-pipe a whole new pipes exposed. It's gonna look ugly to your beautiful house, but this will give you a peace of mind. Haha...good luck.

Hi Momo Sang,

Finallly the root cause was able to detect and coming from my neighbhor pipe and they had rectiied it and pending the wall dry up.

Thanks

Thank you for your advice and finally, able to find the root cause .

Good to hear that you have found the root cause of it.
Actually it happened to me also, but was the other way round, my neighbour wondering why his house wall is leaking like there is no tomorrow. Then found out after my house leak is fixed, he don't see his walls wet already. Hahahahah...

Sometimes depends on lady luck. And was told my neighbhor using all those blue color pipe and easily burst with pressure especially house installed with water pump

Buteline is the best plumbing solution. Easily last you 25+ years without worry about leaks.

Hi Michealck1838, could you share your experience on how you manage to find the root cause? Was it internal piping? I'm also having similar issue with my neighbor.

Did an visual inspection at neighbour's wall and found some wet surface and quite sure is an internal pipe leaking.

Hi wanted to ask advise on water leaking issue at my house. I live in a double storey house. I've detected a leaking at the stop cork below my ground floor kitchen sink. As the pipes are concealed, i've requested the plumber to re-pipe (external) from main to my water tank to bypass the internal pipes. After repiping, the stop cork area is still leaking water after 3 days.


I was thinking it could be residue water in the internal pipes that haven't cleared, but it seems to be still leaking after 3 days. Anyone has similar experience and how you resolved it?

Didnt the plumber check whether it is the worn our rubber seal inside the stop cock before repiping or was it your idea to repipe without checking ?
Btw, if is the rubber seal, it cost less than a ringgit.

It was my idea to repipe as there is problem with my internal pipings, it is giving way one by one. Most of the other residents in my Taman also face the same issue. Hmm..maybe it is a good idea to ask him to check if the rubber seal worn out at the stop cock. Anyway since the pipes have been bypassed, there shouldn't be any water running through the said pipe right? My friend has asked me to monitor for another day or two to see if it is the remaining water in the pipes. Thanks.

Got pic of your stop cock, maybe hv better idea to give suggestions

Some times it just easy to diy

Hi this is the picture of my stop cock. It is below my kitchen sink.

I read your post again ...

If you repipe to the reserve tank only, where did the water to the sink come from ?

The plumber did a new piping for the sink area ? If yes, then it shouldnt have water in the old piping. All water to sink are from the main.

Hi Mini Orchard,
For the water to my kitchen sink it is from the roof. My kitchen is at the back of the house. So there is a new external pipe from the roof which connects back from the back of the house to my kitchen to supply the water to my sink. Yes, you are right, there shouldn't be water in the old pipe. I am still trying to figure out the issue.

If close the stop cock, will the water keep coming out?

Then remove the stopcock using a spanner to see whether there is any water flowing out.

If the old piping is from the main, then it shouldnt have water. Otherwise, the piping could be from the reserve tank and it also leads to the bathroom.

When i close the stop cock, water still flows out.

Thanks for all the inputs. I will take into consideration. Will update how the issue is resolved here.

I've removed the stop cock and there seems to be no water coming out of the pipe. But there are water seeping out from the surrounding surface of the pipe. I'm just thinking now it could be a leak from the neighbour as I am living in a double storey terrace house and share the same wall with a neighbour.

Yes. Quite high possibility

Luckily u r not doing any cabinet to cover up the stopcock area or else u won't be able to see any leaking

Yes i agree, with this experience, quite fearful of concealed pipes now. Once there is problem, it can be a nightmare.

Better re-piping to exterior.

I requested my neighbour to switch off the main supply for his house. After one night, the leaking stopped. The leak is coming from my neighbour. Moreover, my neighbour's house is slightly higher than mine.

So your neighbour should do repiping and not you. Leaking should be check thoroughly b4 doing, otherwise is waste of money. Even have to break some tiles, I will do it.

Hello sifus,

I am having a problem with rainwater leaking into the kitchen, during heavy rain.

First time home owner. Condo. Had coring done for kitchen hood.

At first suspected it's the windows silicone and got it fixed. When it rained again, water started to seep in and collected at the kitchen floor.

Suspected the exhaust outlet (coring) and found out the wall is wet. The water must have seeped through the exhaust fan and through the wall until it gets into the kitchen.

Is there any way to fix this problem? Sooner or later the water will damage the kitchen cabinet Any suggestions to fix this? Thank you in advance.

Take a wider photo of the area. Nothing much to see now. Include both indoor and outdoor view.

If due to the heavy splash of the rain, normally you will need some sort of louver at the external to prevent the rain water from splashing into the cored hole. The better way will be coring the exhaust hole slightly slanted to the external, the slant / gradient will allow any water coming in to be drained out via gravity.

Hi is there any good leaking contractor recommendation? Me having same issue where water bill suddenly shot up but with no visible signs of wet walls. Now I don’t know where could be the source of the leak.
