Hi,
(re-fitting an existing double glazed door)
This seems to be a great site. My double glazed kitchen door was installed in the cavity left after the wooden door was removed. Unfortunately the builder did not make an allowance for the UPVC door frame. As a result, Apart from the existing inner step in the kitchen, one has to climb over the frame. The drop on the other side is therefore quite a lot. (To make matters worse, my dog flap is also much higher, leading to an unhappy pooch).
My question was:
Is it relatively straightforward to remove the door, cut a channel in the step to the depth of the frame, and then re-install the door and fill in the gap on top of the door? The entire door will be lower, but almost flush with the tread / step below.
Hope to hear from you soon. Cheers
