Would removing the back-board of cupboards help against mould/mold?

In our new (to us) semi-basement flat we have a relatively small condensation problem, generally behind cupboards... kitchen cabinets, bathroom cabinets and wardrobes.

I'm thinking of removing the back boards for all of them, for the following reasons..

1 They are mould contaminated already

2 Not knowing if the last clean is working is worrying, this way it can be monitored easily

3 New mould can be attacked immediately, without having to move/dismantle anything

4 More air can circulate


What are the downsides of not having back to cupboards? Are they necessary, structrural or in any way important that I just don-t know about?


They are structural, but if you leave the mounting rails at top and bottom, the middle could be opened, if the cabinet have a normal load.

A full back helps resist racking. Its less important if several cabinets are attached together as a group.

Of course, exterior water intrusion is your real culprit and the best focus during the spring: downspouts and reversed grade toward house are the two most common causes.

    You can compensate for any strength loss, by adding more screws into the wall. – Bryce Jan 28 '14 at 5:49

    A series of 4" holes (rent a hole saw bit) will give you 80% of the drying and leave 90% of the strength. (Numbers are made up, but roughly correct). – Bryce Jan 28 '14 at 9:32
