I recommend them. Very affordable, got things done quickly and efficiently but you have to be on top of them. Over all they did a pretty good job. The guy travels to Korea a lot so just make sure he will be around for the duration of the job. Only issue was the guy he recommend for the construction came and sub contracted the project out to another party. They did finish on time.
