thermal imaging to find external leak on house?

hi
we have a newly built house, just a year old.
during the really bad weather, we have noticed water coming in around the window reveal. this is only happening when the rain is driving against the house for an extended lenght of time.

we have now removed part of the internal reveal, and we can see the the blocks are pretty wet, especially if its lashing outside.

there is no real visisble problems with the structure of the house, and we think it may have been the windows that werent sealed properly at the time. which we have resealed, and there does seem to be less coming in now.

so, to try to get to the root of the issue, and with out having to tear out anymore slabs / insulations, i was wondering about the possibilities of using theremal imaging on the house, to locate cold, wet patches on the house?

so if anyone has used it, or has any experience with it, can you let me know if it worked for you.




also should add, that its not an internal pipe leak.
the house has a cavity, and this is pumped with insulation.
and its the inner block, which the cosy board sits on, that was wet.


thanks
