Hello all,

I am attempting to install a light switch in my living room, but the horizonal wooden stirps which are behind the wall, is broken directly behind the light switch, thus I have nothing to screw the light switch into, to secure it.

Furthermore, I tried to install a light switch holder (a face place with about an 2" depth (to accommodate the wiring) and i thought this might work because it uses 4 screws to secure to the wall, instead of the 2 in the light switch, but again, the same problem: the screws have nothing to secure to.

Please see the attached photos, for a clearer picture of my problem.

Any help would be greatly appreciated,

thank you in advance

Hi b274
Probably the best chance is to use a deep dry lining box. You may have to use odd bits of timber and expanding foam to secure the box in place.

thanks for you comment

Can I drill into expanding foam?

Hi b427
Yes easily but it’s mot suitable for fixing into, so you could foam around the box so it’s stuck in place
