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..

Spoke to Dennis over the phone about a replacement for a broken pane of my double glazed kitchen window. He quoted a price and was out to fix the window within a week as stated. The work was done to a high standard and very efficiently. Would recommend to anyone who is needing this type of work. Thanks Dennis.

Dennis was absolutely wonderful. He could not fix the door completely on the first visit, but was able to open it and made it safe for us and lockable.He came back the next day with the parts to repair the door fully, and even did some preventative maintenance on the patio doors and other doors in the house for us free of charge.We found him to be an excellent, honest and trustworthy tradesman who cares about doing a good job at a fair price.We would certainly recommend him.

A big thank you to Dennis of Castle UPVC repairs for saving my old double glazed window by installing new window lock gears and locking points so a new window was not needed. Very professional service and able to adapt old parts not available as spares to new parts that are available to correct the problem.

My wife and I are over the moon with Den's work from Castle Lock and Hinge. We we're told by another company that we would need all of our windows replacing which was going to cost a lot, we then went to Den and he identified and replaced our misted panes and resealed them and now they are like new at a fraction of the cost! Brilliant!!!
