About Castle Lock and Hinge

Castle Lock and Hinge is an established local company serving South Durham and Teesdale for uPVC window repairs and uPVC door repairs. With over 35 years experience, we are fully equipped for upgrading and repairing worn out locking mechanisms on all types of windows and doors. 

Over the years window and door hardware degrades and eventually needs replacing, unfortunately it is not always possible to get the company who installed your windows and doors to come and fix them as quite often they have gone out of business or have changed their hardware supplier.

We are the go to company when it comes sourcing parts and locking systems as over the years we have built relationships with most of the major hardware distributors, it is rare to come across something we can't match. We are confident we can match products installed by all of the local window companies past and present and guarantee to fit only premium quality products.

We are also suppliers and installers of replacement sealed double glazed units, why replace the whole window when we can replace the glass at a fraction of the cost of the whole window.
