foundation dry rot

My grandmother's 100 yo house was built about 6 inches from the ground, their is now a mildew problem from the dry rot caused by the floors being so close to the ground. There is no subfloor.
The foundation floor joists are rotting.
To repair the foundation joists, could the floor be pulled up, joist jacked up and bamboo planks wedged in?
I have heard boric acid helps control dry rot?
Is there an appropriate insulation that could be sprayed under the floors?
Thank you very much for any expert advice!

With no crawl space under the house, you will have no other choice but to do the repairs from the top. While you're at it, lowering the ground level would be a good idea, as long as you're not creating a well under the house that will collect water when the rainy season comes.

You will need the opinions of some experts, who will come to your house, look at it, assess the condition and recommend a course of action.

there is no question that you need something done right away. If your joists are no good, what do you got to support your house? Don't wait for your house to start caving in.

And Spruce's idea to dig for a crawl space is good, for right now and for future repairs.

There are house moving companies that can raise the house a few more cinder blocks and level it at the same time. Some of these companies also repair the rotted structural elements. Get a few quotes. They may give 'by the foot' pricing for structural repairs if there isn't much room to crawl around.

The house will need to be disconnected from the sewer, water, gas, and possibly the electric for the house to be raised, but this isn't difficult.

Get a number of estimates

We too have an old house. We need sill replacement as well. Where do you find qualified people for this project? It is not just a simple carpentry issue. We also have two fireplaces to consider?

1 - Get referrals from trusted family and friends.
2 - Always get at least 3 quotes.
3 - NEVER choose a quote based on price.
4 - Check licenses, insurance, bonding, and references before hiring the contractor.
5 - Changing out a sill plate can be done by any good general building contractor, you don't necessarily need a foundation expert.

You're right - it's not simple carpentry, but carpenters do repair things like these. They are the ones to call for estimates.
