Bathroom Door Lock Installation – Stockton-on-Tees I need a lock fitted to my bathroom door, as it currently has no lock. Ideally, it should be a lock that can also be opened from outside with a key in case of an emergency. I am sending pictures of the door for assessment. Please bring a suitable lock and all necessary materials yourself. Include the cost of everything, including the lock and installation, in your quotation. Location: Stockton-on-Tees.
