We needed the interior limestone walls of an historic hill country house blasted. The walls had 90 years of fireplace soot and grime on them. To add insult to injury, someone had also painted the rocks in ridiculous rainbow colors. Ace was one of three companies we asked for a bid. Their bid was in the middle, and they explained the process better than the less expensive bid. They understood the historic nature of the building and left us confident the house would be in good hands. They were responsive to our emails and texts, and arrived on schedule. They agreed to a written description of the job, and even volunteered to do a few extra things when they were done.
This is a family run business, and they were all a delight to work with. We are extremely happy with the job; the house is so bright and fresh looking now!
A note to anyone who is considering this sort of process: be prepared for everything you own, and everything in your garden, to be coated with white "baby powder" at the end. You will spend days- maybe weeks- washing and drying everything. It's best to do this when you aren't trying to live in the house. But the results are stunning.
I'll post some before and after pix if I can figure out how...
