How to identify source of water coming into house?

[con_66]

Recently repainted bedroom and added new built ins. When old carpet lifted to relay new carpet there were two damp patches on yellow tongue flooring. Plumber has indicted sub floor - no water leaks. Builder indicted bricks/windows/roof - no water entry points. Two different areas of room. Have used dehumidifier/drying. Surface dries then hours later wet again. Subfloor area dry. House on piers. Any suggestions of what to do? Desperate!!!!

Hi Eric. Thank you for all the info. 
Flooring that is damp is yellow tongue flooring in two different areas of room. Plumber, building/pest inspector have examined boards underneath damp patch (underside of boards dry except gif a very small area). No moisture detected in any other floor areas, walls, ceiling or roof cavity. House on bearers and joists. No water damage or moisture in sub floor area.

Hi @con_66,

As @Dave-1 has mentioned, your best option is to have a leak detection specialist attend.

They are not the same as a building and pest inspector. As this is their specialty, they will be better equipped to give you a solid answer.

Evening @con_66 

Cruising into town today I was thinking of your problem I was trying to think outsode the circle and have a couple of ideas to throw in the ring.

You know those water absorbing beads? DampFree 300g Disposable Moisture Absorbers - 2 Pack Put them in the middle of the damp patch, turn a clear large container upside down and tape it to the floor to seal the edges. It may pull the moisture from the boards.

Second idea, Using same said bucket, place it in the center of the damp areaand see if water is dripped into it from above. That will eliminate two potential ways that damp patch may be appearing. I fully get you may have tried both but really want you to know that with all the questions in here, someone will find or point towards an answer that may work for you.

Ideas never stop!

Hi All, thanks for all suggestions to get a leak detection specialist in. Followed advice and booked one. Paid a call out fee first up then thru booked in the “specialist” to do the inspection. They then rescheduled twice. Third time the guy who arrived wasn’t the person who i eas told initially would do inspection. The guy used a thermal imaging camera, took some photos, used a moisture metre. All up they were here fir about 35 minutes and charged me $850. They didn’t test pipes or inspect under floor area. I’ve asked company for the contractors name, licence number and connection to company I initially engaged with. They refused. So getting the leak detection testing has been a disaster and I’m no closer to knowing what the issue is

The leak specialist I would have presumed would be check water pipes pressure wise as well, plus any drains. As you have stated it wasnt the person you thought would be doing the checking. I would be discussing this with the company itself. I wouldnt expect to be given the contractors name as its the company you have aksed for the test to be done. Explain what and how the testing was done and ask if that is normal for a specialist to do. If the answer isnt to your liking then the department of fair trading would be the next stop (different states will have different gov bodies)

I find talking is far better to get a resolution then going down the hard path of a goverment body.

Thanks for your reply Dave. I’m not sure you understand the issues though. I engaged one company who allocated a specific qualified contractor by name to complete the work. That was what I agreed to. The specialist was not available the third time they changed the appt, so they sent the father of the contractor. I did not agree or engage a third party. I am entitled to know the contractors name and licence. I have asked company and they’ve refused. Sounds like you want to stick with the guys without knowing the details. As I engaged a specific specialist due to the complex nature of water ingress, I expected that service. I didn’t get the service and they used a person who seemingly, given the sub standard inspection, didn’t know what he was doing.

Hi @con_66 

I'm sorry to hear that your experience with the leak detection specialist was not a positive one. I can only suggest contacting the owner/manager again to see if they can resolve your query.

If you need further assistance, please let us know.

Eric
