Refitting alarm sensors on windows and doors
If you are replacing windows and doors then the alarm sensors located on the old ones will have to be removed and then put back up on the new ones. If the original sensors are old then best replace them with new sensors.
Gard can do this for most alarm systems and the price will depend on the time taken which depends on the number of windows and doors. Also whether you require new sensors or wish to keep the old ones.
