Window and Ventilation Locks
Most new build homes now are fitted with window locks as standard, although most just lock the window in the closed position. In some instances (hot weather) it is nice to be able to secure the window to allow ventilation without compromising security, fitting an additional restrictor will achieve this.
If you do not have window locks fitted it is worth checking your insurance policy, as most will require them. Andy Stott Locksmiths can supply and fit locks and restrictors for all types of window.
