Borate Cabin Fungicides

Borate 
You should get the house borated between blasting and staining.  This is the only time it can be done as borate needs to be applied to bare wood and you have to let it dry.  Again, time to do it right.  Time to wet the house down, time to apply the borate.  Time is money.  This should be a part of your price.  If it isn’t, ask up front how much to add it to the scope before signing the contract.
