When I add a subdivision surface modifier to this mesh, the mesh seems to have holes in. Looks like the faces become rounded with emptiness towards the ends of the face.
Does anyone have any idea why this has happened?
Thank you!

If the faces are loose, you can try and select all vertices and merge by distance (set a distance that doesn't destroy any faces but will merge the vertices that are overlapping / almost overlapping. $\endgroup$– Alexandre MarcatiJan 16, 2022 at 13:09

$\begingroup$ if u provide blend file, we can check it out... $\endgroup$– ChrisJan 16, 2022 at 13:16

$\begingroup$ Hi, congrats on your first question here! If Alexandre Marcati's above comment doesn't help then it'd probably be a good idea to post your blend file, or a truncated version of it that has the problem. The Blender StackExchange has its own service to share blend files: blend-exchange.com/help $\endgroup$– KickAir8pJan 16, 2022 at 16:57

$\begingroup$ Any chance you're also using an Edge-split modifier? $\endgroup$– Christopher BennettJan 16, 2022 at 17:19

If the faces are loose, you can try and select all vertices and merge by distance (set a small enough distance that doesn't destroy any faces but will still merge the vertices that are overlapping / almost overlapping).
