About 20 years old, we have a cedar greenhouse where the soil has crept
up
on one side over the
lowest board and it is rotting, causing the whole structure to lean
over
slightly.
Is there any way of resolving this? I can only think of propping up
the ridge with a pole and a couple of acrojacks to bring it back and
take
the weight off the bottom whilst remedial action is applied.
Are you sure it's not just settled on that side due to soft
foundations?
Not when the old wood comes away in handfuls if you do so much as to
breathe
on it :-)
Surely the glass would not allow it to subside so it must be the
foundations?

Not sure what you mean, but as one side subsides due to the rotting
wooden base, then the distortion of the frame on that side causes the glass
to crack
and then the resultant distortion on the rest of the structure causes
further panes to crack.

_HOWEVER_ having just picked up the anniversary edition of Gardener's World,
and seen the insertion from the www.greenhousepeople.com inside, we've
decided to cut our losses and order an aluminium (aluminum for any Yanks
reading
this :-) ) replacement from their double discount offers.
