Just back from picking open and re-keying four patio doors. They were fitted with multipoint locking strips. Oh, my! The worst catalogue of errors I’ve yet seen – apart that is from using masking tape – except too much masking tape.
The builders had applied masking tape to the MPL strips. But they’d left it on! So when the doors were locked and all the wonderful (ahem!) panoply of bolts had sprung out, they’d had to spring out though the masking tape. This has gone wrong in one door and now it can’t be unlocked. And that’s expensive with an MPL.
Then having painted the doors, they shut and locked them with the paint wet. So now they’ll have to be sanded and painted again as the paint films had to be cut and broken.
Three of the four handle sets had been fitted the wrong way around with the securing screw heads on the outside. Just where your burglar needs them.
And of course all the cylinders were far too long.
So, once again, the advice has to be: watch your painters like a hawk. Get them to use masking tape – and take it off again. And ask them what their plans are for allowing the paint to dry before closing.
