Regardless of the age or manufacturer of your door or window, we are confident that we can replace and upgrade your locks and also you will be delighted with our lock fitting service.
Types of locks we can replace
There are many different types of locks fitted to doors such as mortice and multipoint locks. We realise that it can be confusing to the general public regarding what type of lock you have and also the best type of high security locks you need. It is important to ensure that the correct type is fitted to your door, thus keeping your family and home as secure as possible. With over twenty years of experience in the locksmith industry, we know what is needed and how it should be fitted.
On wooden doors you will find either a mortice lock, this should be five lever and British Standard or a night-latch. uPVC doors have a multipoint lock and euro cylinder for security. These can, and do, fail after time; but all locks are carried on our specially designed mobile van to ensure that your door lock is repaired or replaced the same day we visit.
