Window & Patio Door Locks: common questions
Can you fit locks to windows that don't have them?
Usually, yes. Your locksmith will check the frame and suggest a suitable lock or lockable handle.
My patio door is hard to lock. Is that a lock problem?
Often it's alignment. Adjusting the rollers or keeps can stop the lock being strained and failing.
How much will it cost?
It depends on the lock, the work and the time of day. Your locksmith will tell you the price before starting, and nothing goes ahead until you agree.
