We paid about $4,000 to have the stone in our backyard cleaned and sealed. The work they did was good enough that I called them a second time when we needed more work done.
About a year later (June 2017) I called them to do some additional work - they did not respond for about a week. I finally got a response after several emails and phone calls to them. Tom finally called back and provided a lengthly response that they were "partying" at the "lake". Tom said he would head to our place in the next month to look at the stone and let us know what needed to be done. They never came out and they they never called to let me know they couldn't or didn't want to do the job. When you are in a service based business its important to be timely, reliable and act in a professional manner - I did not get that the second time around.
