Waterproof paint stops condensation entering a wall, and thus causing damp/mould. It does not stop water leaking out from behind a wall, which seems to often be from a damaged pipe/coupling. So a) the landlord is not taking the matter seriously, and b) good on the contractor for refusing to do work that might only make the matter worse.amarettoSour wrote:He still did not want to fix the issue, and sent a contractor to paint with waterproof paint instead.

Difficult; and water leaks are a tricky thing. Especially in buildings with partition floors. Water can leak into a floor at one side of an apartment, and exit via the ceiling of the unit below at totally the opposite side of the room, or even flat. Tracing leaks 'from upstairs' can thus be difficult, time consuming, and hence $$$. As a worse case it can mean taking off bath panels, or even lifting (wrecking) tiled floors etc., it is one of the biggest headaches a landlord can be faced with IME.amarettoSour wrote:Finally after some angry messages from us they went up to the upstairs unit again and supposedly found a leak from the bathroom upstairs and patched it up. It is now Saturday and the leak has not stopped, and we just do not want to wait anymore.
Well done. First rule if a situation is turning sour, is document document document. Pix, phone calls, e-mail archive, a diary of events... = absolutely priceless, in the case that it does come to law.amarettoSour wrote: All of this was documented in email and there are picture evidence of the leak and the mold.
Do you think it's reasonable for me to tell owner we are moving and ask for the two months deposit back? I suspect there is just a bigger issue with this apartment and i am sick of pushing them to fix it.
Yeah BoC it's tricky, as it can involve several parties, none particularly motivated to try and resolve what can be a surprisingly complex and $$$ problem.Beeroclock wrote:Sometimes these issues get bogged down in arguments between the upstairs owner, condo mgmt and affected owner over responsibility/liability. Not sure if that's a reason here or you just have a lazy/irresponsible LL. good luck, I agree it seems a reasonable grounds to terminate taken together with the LL's failure to act on it.
We had something similar at our previous place, in our bedroom. A large area of upper wall where the air-con unit was positioned became 'dappled' in very fine pale green/white mold. You had to look at the wall a certain angle to even notice it really. This caused me congestion = snoring, = upset wife + tiredness. The dampness also caused mold to grow on our otherwise fresh/clean clothes in the wardrobes, so destroying some of them (the dreaded red mold spots).Beeroclock wrote:As it happens I'm having a similar internal wall leak , but not from above its from within my apartment, and also struggling to find a good contractor. Have called in 3 people so far, a leak " specialist", plumber, and air con man. Only the latter gave my much confidence he knew what the problem was. So I am also taking longer than desired to fix it as I don't want someone randomly hacking my wall!
Yeah this sounds very much like what we have. The damp area starts about 1m below the ceiling so it can't be from above. We had to figure out if it's an internal water pipe or air con pipe. However the lack of a major leak, just slowly accumulating damp patch and mold, implies it's not a water pipe which even with a small pinhole leak should lead to more water coming out by now. First contractor didn't really know but just proposed to hack the wall and explore, without being able to give a firm quote either until he sees what's there. This seems risky to me and almost like signing a blank cheque. Second the plumber also doesn't really know but suspects it's the air con system, but wants to do a pressure test anyway for $200+ to confirm water pipes are not leaking. He also suggest me to call air con man. So I did that without doing the pressure test which I was not sure would prove anything. Finally, the aircon man who is confident it's a drain pipe leak from one of the air con units and asks us to stop using this particular unit to see if the wall dries out. It's been almost a month now, and it is much drier but I'm still not completely certain ! If I can pinpoint the cause to the aircon then I might be able to run an external drain pipe as an alternative fix to hacking the walls.JR8 wrote:A large area of upper wall where the air-con unit was positioned became 'dappled' in very fine pale green/white mold.

It transpired that it derived from the air-con unit. Specifically the drainage-hose had become uncoupled within the wall itself. Causing leakage inside the wall. The remedy was going to be 'hack' the wall until they could find and repair the broken pipe joint. That would have meant us moving out of our bedroom with all possessions. Contractors, mess, maybe even alternative accommodation. You can see why LLs can seek to overlook it.
In our case we were leaving not long after that problem arose, so it wasn't resolved during our time there. Oh and apparently something similar had happened before in that same unit (our friendly agent explained), and that might be why the owner was so reluctant to act: He knew what a minefield it was.
A pressure test on what? The internal gas system of the air-con - that's the only type of 'pressure-test' I've seen being done. Or some form of pressure test of your apartments internal plumbing system? I've not heard of the latter being tried, and am not sure if/how it could prove a leak at a specific location. More to the point the air-con condensate drain-pipe is (AFAIK) not pressurised. Oh and pressurised water pipes don't usually run along walls at ceiling height or therabouts. They often run laterally at floor level, and have 90-degree junctions/spurs off, rising up walls, as required, to specific points (taps, shower-heads, toilet cisterns etc). So if you shared those same doubts, then yes, me too!Beeroclock wrote:Second the plumber also doesn't really know but suspects it's the air con system, but wants to do a pressure test anyway for $200+ to confirm water pipes are not leaking.

If it's a structural wall, it can take weeks to dry out, and that's in the UK with low humidity. So here with far higher humidity I wouldn't be surprised that the dry-out rate is equally slower.Beeroclock wrote:Finally, the aircon man who is confident it's a drain pipe leak from one of the air con units and asks us to stop using this particular unit to see if the wall dries out.

They did this last month and no colored water made it into our unit. This is why i think the matter is complicated bc they cant pinpoint where the leak is coming from. Last week they patched something from the sides of the bath tub upstairs since it could be water seeping in from there. Keep in mind that was the only repair that has been done sincr Jan/feb, when we first made noise about this, so of course we are losing patience.martincymru wrote:put red dye into the water system upstairs, if red dye in your room you have found the source.

Yes condo. MO took a look and promptly adjudicated that it was internal to my apartment and therefore not their problem. I did ask them for recommended contractors, one of whom was the aforementioned plumber...JR8 wrote: I forget, did you say you're in a condo? If so have you spoken to the management office? If you're having a problem, it's entirely possible others have had too. And the MO might/should be able to suggest a contractor, i.e. one known/used by the MO, who therefore will be under an expectation of doing a decent job.

Would it be possible to disconnect the drain hose within the air-con unit, and attach a by-pass hose (perhaps similar to the pvc tubing used for home-brewing? You could search on-line for lay-out and parts lists for the condensor, and this should show you where the drain is, and the dimension of the pipe/coupling). The hose could simply hang and terminate/drain in a bucket on the floor. Running the air-con like this for a couple more weeks would also have the benefit of drying the wall. Running a surface-mounted pipe is not a pretty thing, but the temporary by-pass test might help confirm the problem is the current in-wall drain-pipe.
