Mold removal professional

[denisalfin 0]

The corner (top and bottom) in my master bedroom is constantly growing mold. My attempts to clean it off myself have failed, and is now spreading a little bit down the wall. I searched the forums, but i didnt see any experiences on how much having a professional come remove mold would be. Is this too small of a problem to have someone come in for based off what im saying? Is this something that would be sub €500 or are mould removal guys pretty expensive around here (Bavaria)

It could cost you € 3,50 for a mould remover spray and an hour of work.

 

You can have professional come and remove it. For some 2-300 € I'd say. But that's not going to prevent the mould from coming back. Soon. You have to avoid mould, means you have to heat and vent the proper way.

Room not too cold,at least durong the day when you don't sleep in it. Bedrooms need venting at least 15 minutes per day with fully open windows.

Are you sure that just removing it is going to help? If it keeps coming back maybe there is a problem with damp walls, you might need to get that checked.

I have to say that I agree with Uncle Nick, the few encounters I have had with mold have not been trivially fixed with a bit of mold spray. This has, cosmetically improved the situation but had no significant lasting impact. Dealing with the underlying cause (generally just fixing ventilation problems) is the most important thing, then you probably need to deal with the mold and maybe repaint the area.

As Uncle Nick said, assuming the room is ventilated sufficiently in the morning to dissipate the volume of moisture expelled overnight by (2?) sleeping humans, if the mould keeps returning there's a good chance that water is entering the structure of the wall/s from outside.

 

How simple or complex it might be to locate and eradicate the source will depend on factors like which floor the bedroom is on, the direction the corner is facing in relation to the it's exposure to sunshine (or lack thereof) and the direction of prevailing winds.

 

Possible causes of wet walls in upper floors can be leaves or other debris blocking down pipes and allowing overflow to pour into the (often least well sealed) section of wall directly behind the guttering under the roof overhang. Even in less acute situations, such as a partial restriction of a down flow pipe, prevailing winds which often accompany heavy rain can cause such localized soaking of vulnerable wall sections. Of course any leaks due to slipped, lifted or missing roof tiles, ridge capping or flashing can also provide a direct water flow route into an upper wall section.

 

Cracked or missing exterior wall surfacing (Wandputz), particularly if any form of flora ranging from moss to ivy has gained a foothold, can provide a similar access path on any floor of a building.

 

Mould and rising damp due to water ingress in ground floor walls can be due to local sub-surface flooding as a result of blocked or damaged piping (rain, waste or fresh water or sewerage) in the immediate surrounding area. Road construction or repairs, the movement of exceptionally heavy loads, local subsidence of old mining workings, minor earthquakes or the growth of large tree roots are all potential causes of subsurface flooding which often continues unreported until people begin to notice mould caused by wet walls.

Or in the worst case...(i.e. mine!) it could involve engineers(2), lawyers(3), endless comittee meetings (4 so far, and the work hasn't even begun or been approved yet), and having to move out for a year while they tear down the walls, rip up the floors and start from scratch! :(

Does anyone know how much it will cost to have someone test for mold at home?

You should be able to buy DIY testkits in a pharmacy or even in a Baumarkt. Here is one available on ebay: https://www.ebay.de/itm/MELLERUD-Schimmelpilz-Schnelltest-zuverlassiger-Schimmeltest-1-Stuck-891620/324069645622?epid=1805210190&hash=item4b740e5d36:g:QDUAAOSwChteQoTK

Baufix seems to clean it up proper enough.

 

you have to follow the instructions, spray it 3 or 4 times. Don’t wipe it away, just wait for it to die.
