Can anyone recommend: UPVC lock replacements
We have recently had new patio doors installed on 3 balconies and 2 windows in our townhouse in Meia Praia, Lagos and 3 of the locking mechanisms do not work - but the builder has refused to give us the name of the supplier or the guarantee, and has effectively disappeared. Does anyone know if it is possible to retrofit locks/handles made by a different manufacturer to the original.
