Sealed unit has condensation in it; can we remove the unit as it would appear that the seal has gone? Would it be possible to then use the same unit by resealing it.

you can re-seal the unit but unless its a leaded fanlight or georgian bar to match existing units, its far easier to replace, generally, any units with a blown seal get watermarks inside which cannot be removed! Ive spent hours trying to get rid of them for customers who think its cheaper to use the same glass!

There are many companies that reseal them,look in your local Yellow Pages,that's the easiest way.
