Houses with pyrite

I see a few houses that have pyrite for sale, they are only for cash buyers because of this.
Is it a big issue to get sorted? What type of cost or time would it take to sort it out?

All things considering, it’s a simple fix.
It’s complete removal of the ground floor slab in order tin remove the sun floor build up.

Then start again with the appropriate aggregate, membranes, insulation and slab.

The biggest problem is the intrusive nature of the fix as it requires complete removal of every ground floor fixture and renovations afterwards.

Any particular reason why an owner wouldn't get it fixed? Why sell a house with pyrite if it's easy to fix?

Don't touch them with a barge pole. They are nothing but trouble and unless you have deep enough pockets for the unknown that you might find when you dig out the floors, steer clear.
The average cost depends on floor area but I think cost 40-50-60k. In addition, don't buy any that are Semi D or terraced because if the houses either side aren't done, you are going to have a problem down the line.

Probably can’t get the grant or costs covered under the pyrite remediation scheme so obviously the cost of the Boise should be substantially cheaper than those around it.

What could you possibly find under the slab that will be a night mare?
Every ounce of material under the slab will be skipped anyway as part of the removal process.

How can a house on the other side of the party wall effect the house?
The sun floor fill will be separated by the rising wall (party wall).

I have heard of people spending thousands when they realise the slab is twice the thickness expected, or the foundations are already in bad shape from the pyrite damage, etc.

Re the adjoining property - because the expansion of the pyrite can exert pressure on the bottom of the party wall and can weaken the blocks over time. So if the houses either side are not done, then you will potentially have a problem down the line.

By no means an expert, just what I have heard.
