second floor porch separating from house
We live in an 1870 Victorian Carraige House in a Victorian neighborhood in Willimantic, CT. We have a second floor side porch that is separating (pulling away) from the house. The porch is supported by beams that are just sitting on the ground or on plain bricks. Over the years, with the frost heaves (the ground freezes in the winter then thaws again, thus raising and lowering the beams), we believe that the ground under the beams has sunk, thus allowing the porch (that they support) to come away from the house.
Does anyone have any suggestions on how to fix this problem? Will raising the porch back up again (jacking it up and putting new beams in that rest on concrete) cause more peoblems? Thanks for any advice.
