Just bought a new house .Every wire has been cut tv/ sky / telephones and Burglar alarms ! ( great eh?)I got an engineer out as we did not know the pin for the alarm and would need it reset he said all the sensors were cut so basically would not be worth to join them up etc.We obviously need a new alarm , However we still have to remove the old burglar alarm.The box is in the passage but the wiring must be located under the floorboards????What do we do?? i dont want all floorboards lifted etc .The company who initially installed alarm is no longer there .We bought the house but it was rented for years hence the wiring mess.Any help appreciated
