Wall safes are specifically designed to be secured within a cut out section in a wall as opposed to a standard type safe which you bolt to a wall or floor and this is a free standing type of safe.
Whether a wall safe is suitable to be installed in your home would be determined by the type of walling you have within your property. Firstly, a wall safe needs to be cut into a brick, block or masonry wall and concreted in, so you need to have a suitable site within your property to place the safe. A good site is a brick chimney breast which gives plenty of space.
Good insulation is also necessary. Because exterior/internal brick walls can ‘breathe’, condensation can build up around the safe which can cause damage to locking mechanisms over a long period of time and can get inside the safe damaging items within. To avoid this happening, adding additional insulation or a waterproof membrane around the safe prior to the concrete being added is a good idea. It is then advisable to allow the site to settle for 7 days prior to first use while any moisture from the concrete dissipates.
Once installed and settled, a wall safe provides a good, secure space to lock away your valuable items and documents, hidden from view behind a photo, picture or even a ‘false’ front. Some people prefer the ‘hidden’ nature of a wall safe, however having a safe installed into a wall does not give you any greater insurance cover and as with any safe it is important to check with your insurance company that your policy covers items placed within it in the event of theft.
Finally, as wall safes can be more involved to install, it is worth seeking professional advice prior to purchase.
