ᐅ How can I securely mount Billy shelves on walls in older buildings?

Hello everyone, I would like to securely fix my Billy bookshelf to an old building wall but I’m unsure about the best way to do this. The walls are partly quite crumbly and have uneven plaster areas, so standard wall plugs don’t hold well. Additionally, some of the walls are solid masonry, while others are partly timber-framed or even made of thinner materials. My question is: How can I securely attach Billy bookshelves to such old building walls so that they don’t fall off or become unsafe after a short time? Are there any special fasteners or methods that are particularly recommended for old building walls? I would appreciate any specific recommendations and practical tips, as the shelf will need to carry a significant amount of weight and stability is very important. Thanks!

Hello Sincolton, I’d be happy to help you here. It is often challenging with older walls because you have different materials and conditions. In general:

- For solid walls (brick, stone), I recommend using traditional anchors combined with screws suitable for the material. Fischer or similar brands offer special heavy-duty anchors that often hold even under slight vibrations.

- For fragile plaster areas, you should first check if the plaster is firmly attached to the wall. If not, it is better to drill into the masonry behind it, possibly removing some plaster first with a hammer drill.

- For timber studs or thinner walls: fastening directly to the wooden frame is advisable, for example with long wood screws. If that is not possible, there are special toggle bolts or cavity anchors that provide better hold.

- If you really want to secure the shelf safely, I would also consider distributing the load across several points, for example top and bottom. If possible, also fix the shelf to the floor or screw it to the wall with brackets.

If you have more detailed information about the wall types, I can provide more targeted recommendations.

The most important thing is to use a suitable drill for the type of wall you are working on. For crumbling plaster, you should remove it at the drilling spot and drill directly into the masonry. After that, use heavy-duty wall plugs. Then attach the shelf with appropriate screws.

Hello Sincolton 😊, I understand the challenge with old walls – they can be quite tricky! My advice is to handle the plaster very carefully, just as Kinbu mentioned. When I installed my Billy shelf, I reinforced it with metal brackets attached to the wall and floor, which gave me a really secure feeling – nothing wobbles anymore, no matter how full the shelves are.

Also, a little tip: if you don’t have a solid grip in hollow spaces or thinner areas, heavy-duty anchors or chemical anchors using resin can help – they are a small investment but often very worthwhile in older buildings. This way, the shelf stays firmly in place, and you can enjoy stable stacks of books later on 😄

Good luck!

To address this: Sincolton, knowing whether you are dealing with clay plaster, lime plaster, brick masonry, or timber frame construction is crucial for selecting the right anchors and screws.

For older buildings with clay plaster and timber frame structures, I typically use special cavity or metal anchors (such as Fischer UX or cavity metal anchors) that grip well in the building material and distribute loads effectively.

Another option, especially in fragile masonry, is chemical anchoring with injection mortar, which replaces hammer anchors and conventional plugs. This method provides excellent tensile strength and reliable connections.

Additionally, when planning, always consider where cabinets should be mounted—whether only on the upper shelf or additionally secured through frame screw fixings. Cheap anchors without a specific purpose are definitely not advisable.

Thanks for this tip! The idea of chemical anchors sounds interesting. I actually have mixed walls: partly brick with thick plaster, partly wooden beams visible under thin plaster. I was thinking about avoiding shelves on the thinner wall side, but that would limit the arrangement options.

Are there any experiences regarding how easy or complicated the installation of chemical anchors is? Do you need special tools for this, and what about the handling process? Also, do they really hold permanently, and can I remove them without leaving any residue when I move out?
