Misted Double Glazing 

If you have a misted sealed unit this means that the unit has broken down, however you only have to replace the glass unit, NOT the whole window. We have replaced hundreds of misted double glazing panels providing satisfaction without mess and at a fraction of the cost of fitting a new window..

I recently used Castle Lock and Hinge to replace a number of window units, fit locks onto windows and adjust a number of doors. Dennis was very helpful and courteous throughout, and I'm very happy with the standard of the work done and the manner in which it was carried out . I'm very happy to recommend him to others.

Extremely competent and efficient service. Responded at very short notice and provided temporary repair until full repair could be carried out which was done to time. Would strongly recommend Dennis and his expertise.
