Hi again, everyone!
Today I want to talk to you about the changing temperature (YAY, summer's here) and how that can, and invariably does, impact your uPVC & multipoint locking systems on doors & windows.
So, as the temperature outside changes, metals, wood & uPVC both swell and contract. Once you figure in humidity, you've a veritable cornucopia of movement. Locks are actually quite complex pieces of engineering, even a slight shift in the position of a door for instance, will likely render the lock useless. Often this happens after a period of extreme weather temperatures, our recent visit from the #BeastFromTheEast and the sub-zero climes that it brought were definitely responsible for an increase in gearbox & mech (the internals of your multipoint locking door) failures.
What can you do to insure against this happening?
In conclusion, there are several ways to avoid a crisis locksmith call-out. To keep you both safe & issue free, be sure to follow Key Change's above advice, and if you're lucky we will never need to meet :D
