Sash window, repair cancellation of gremont camlatch handle lock

"Repair or Replace Crescent"

It is said that it is in a state where all the windows cannot be closed and it cannot move.I couldn't make a decision without seeing the actual product, so I decided to ask.

It was like a share house with a view.There was a window in the empty room, but it seems to be sealed to prevent drafts from entering.

Certainly the window does not move from a certain position.One side is fixed.The lever visible through the inaccessible crevice was the cam latch handle.Looking at the details, it seems to be Gremont locks.It wasn't a simple cam latch handle.

In other words, I think the internal Gremont mechanism is broken.I have to remove the window and take out all the parts.Alternatively, the lower shaft of the Gremont mechanism may be loose and out.You don't have to fix it.

These tasks are beyond the scope of locksmiths.

Either way, you'll have to remove the window, turn it upside down, and access it from the bottom.

Even if you remove it, access will be from the outside.The height where the window is located is about 2 meters, and one person cannot work.Even if you borrow the power of the client, there is a possibility of injury.Removing glass windows in high places is dangerous.

Therefore, I recommended that the aluminum sash installation specialist be requested, and left the site.Working at heights is expensive.
