Changing the locks when moving into a new house is an important security measure for several reasons like you don’t know how many copies of the keys are presently out there. By changing your locks, you enhance security and give yourself the peace of mind that you have all the keys. Also, when you move home, your insurance policies may state that if you have not changed your house locks and there is a break-in with no sign of forced entry, they will not cover the theft. In summary, changing the locks is a simple and effective way to secure your new home and protect your belongings and loved ones.
We replace and upgrade all common household locks, including uPVC, composite and timber door locks. If a lock can be repaired sensibly, we’ll tell you, but when it needs replaced we’ll fit a secure, high-quality option and make sure everything works smoothly.
