Failed Unit Repair & Replacement


There are a number of ways people describe failed units...

Fogged up, Foggy, Steamed up, Steamy, Misty, Misted, Cloudy, Clouded, Blown. There's bound to be others but they all mean the same.


Generally speaking it’s when the seal between the two panes of glass has broken down. Whilst there are repair methods available they are not suitable for all cases.


Once a unit is displaying signs of failure the damage may well have been done already. Calcium deposits can stain the surface of the glass if the blown unit has actual water inside.


In addition to re-sealing the unit as it was originally made would require removing from the frame and temporary glazing fitted. The unit would then need to be returned to the factory to be split down, thoroughly cleaned and re-sealed. Then returned to site to re-fit... assuming it hasn’t broken during this lengthy and risky laborious procedure.


The cost can be more than the cost of a new replacement unit, with a full guarantee and none of the hassle. There are times when this is worthwhile; if its patterned glass and is obsolete for example. Otherwise replacement is the better option.


Please send over your dimensions and quantities and please indicate what your frames are made from... ie PVCu, Aluminium, Timber. Also what floor level i.e. Ground or first floor and when the frames were fitted (if known) or whether they appear to be 10 or more years old.
