Correct fix for exterior crack?

tigertrio

I have an exterior vertical crack in my house.

I've been told by loss adjuster it's heat expansion and to install a slip joint, and get a quote from a helifix approved contractor.

The crack is not on a long wall though, its in a corner where to walls meet like this:

                 <3m>
               _______
________|< crack
  <7m>


How am I to know that this is the correct solution?

Warranty provider.

The photos you put on a previous thread did look like thermal cracking. The Helefix system is a good method of retro fitting a movement joint, as slip ties are used. 
If it's the NHBC, they normally pay for the whole amount if it's over a certain price. If it's less they pay nothing.The
It's worth checking how much the price needs to be.

Thanks - but is a movement joint required? The wall is not that long. Why don't they just fill in the crack?

They are paying anything over £1,000.

If they just fill in the crack it might be less than £1,000, and you'll end up paying it. A movement joint should solve the problem if it is a thermal crack. You will still need the crack repaired as well.
