I am working on a Victorian 1880 terraced house 2 up 2 down plus basement.
The outside has been heavily rendered and I am not sure if that was to
straighten things up or to disguise / hide things.
I am fitting the lower room as a kitchen and need to provide ducting from an
internal back wall where the cooker will be to an outside vent which will
exit immediately over a small replacement window approx 3 ft wide. The
ducting is to be slid through the vent site between the plaster ceiling
board and the upstairs floor borads because luckily the joists run along
from window to back wall.
I started to remove the rendering, which seemed quite thick, and discovered
a line of bricks laid on end. I expected to see some sort of lintel. These
bricks must be the lintel in some way unless they " finish " the wall at
this point and the builders rely upon the window frame as a support. Is that
The bricks on end are not well mortared in and as the line goes to the right
they are not vertical, and almost loose. I wonder if movement took place
when the window was replaced and the heavy rendering was used to bind it all
Is it safe?
Apart from the horrors that could befall us from the above I need to know if
it is safe to drill and chop a hole through the top half of two of these
bricks where they join the wall to make access for the ducting and venting
fixture.Its a solid wall, no cavity, would I expect to find a lintel on the
internal part of the wall??
The ducting is fairly vital as there is no natural ventilation apart from
the window and as the ceiling is lower than normal a filter system would be
Any thoughts advice most welcome.
