Ace Duraflo is a pipe restoration business offering an alternative to total home re-piping. Their process uses your home's existing pipes and shoots an epoxy coating through them in order to restore the pipes to a like-new condition. We had this process done to our home. It was more expensive than a traditional copper re-pipe. It did not work. We have had numerous leaks, the last time some damage was incurred to our home. When we viewed a section of the pipe that was removed, there was no coating evident at all in that pipe. Fortunately, we did have a guarantee and they have now agreed to re-pipe our home. Unfortunately, we would never have had this process in the first place now that we are having to go ahead and re-pipe anyway. I would not recommend this business!
