Outdoor tiles, edges against walls

[motora2000]

Hi

Part of our garden is tiled, and there are a few steps up to the lawn.

There is a gap between the floor tiles and the walls, you can probably just about see the gap in the attached picture (ignore debris and poor lighting).

The gap, narrow as it is, exists all around the area at the "junction" between floor and walls.

I am not sure what I should do if anything. Leave it? Put grout there? My concern would be water getting into the gap and causing problems longer term.

Any advice here, please?

Thanks.

Not an outside expert but grouting or filling with anything rigid might be a bad idea- the wall and the steps will almost certainly move differentially during the year, anything rigid will crack.
Is that the house wall? You could try silicon (grey or black might look quite smart), it'll prevent water getting in and under and damaging stuff when it freezes.

Thanks! I think silicone in grey would be good. It's a garden wall....
