We are doing a log restoration just outside of Baltimore in the spring, would love to do another one over there while we're at it. I could to give you a quote, on blasting and restoring the old part of your home, and then finishing everything to mesh together, we mix our pigments on sight, we can do that. My preliminary assesment and quote is free through email pics and measurements. We have reasonable rates, do good work and have lots of referals available.
I know people who have cob blasted and its very messy, thay said they wouldn't ever do that again
