Does "restumping a house" mean that you are going to redo the foundation? Thats a really hard job cause we had to do some of that about 10 years ago. We put on a new addition and the old side needed the foundation to be shorn up so It could take the effects of an addition leaning against it like a butress. The design was like a big "ashelf of concrete" that qwent down about 8 feet to the deepest frostline
Yes the foundations. I'll explan because there may be differences in building styles. Forgive me if you already know this.
Some houses, especialy older styles here, are mounted on short wooden or concrete poles or posts. Rows of these "stumps" are placed in the soil to a depth of 500 millimeters minimum and leveled up.so the top of each stump is level with the next.
A flat plate (called a sole plate) about ( a guess) 2 ft square is placed in the bottom of the hole. The stump placed and the hole filled in. The sole plate stops the stump sinking into the soil.
Bearers, long heavy pieces of timber, are mounted on the stumps connecting across each row of stumps. Joists are mounted crosswise on the bearers. This is basically the subfloor structure.
It is inteded to basically jack up the house in variouse places lifting it off the stumps and leveling the house. Remove the old stumps put in new concrete stumps and sole plates. Additionally the construction team will remove and replace any bearers or joists which may be cracked or rotten install ant caps and allow the house to settle back onto the now level new stumps.
All this work will be carried out with the construction team on their bellies under the house. There is a considerable section (about 1/3 of the house) where there is insufficiant wriggle space for a man. Soil will be dug out to crate a crawl space.
Most modern houses use slab concrete.
We dont have to worry about a frost depth here.
Currently this house has a rather rollercoaster floor. drop a marble on one side of the kitchen and it will roll under the fridge on the other side. MY computer char is on a lean and I can see the back 1/3 of the house actually falling away from the rest of the house.
The carpenter has been and will prepare quotes and options for two sash type windows which are practically falling to pieces and two much smaller vent type windows.
Options we are exploring are Aluminium frame, cantilever, double glazing and sash types.
