Faulty Installation
Our most common request is to correct a faulty installation carried out by a builder during the build of a new property or extension. The doors may have worked fine for a few months but have now started to prove difficult to open or close and this is often caused by the lack of adequate care in packing the glass correctly to ensure the weight of the glass sealed units is transferred to the hinge side. If this is not done correctly it will simply drag the unsupported side of the door down until it pulls out the weather seals or damages the door threshold.
The consequence of a dropped door will also make locking the door difficult resulting in the necessity of forcing the handle which ultimately will break off and/or damage the lock itself.
