Very helpful at the start, but thats about it. Do yourself a favor and go somewhere else, even the city if you have to, it will be worth it in the long run. Once you pay them, you’re on your own. Incorrect material or quantity? –Too bad, not their fault. Problems with installers not showing up? –Too bad, your problem now. Problems with the install, /not completed? –Too bad, your problem. If you’ve already paid, don’t expect them to return your calls or help in any way that could be considered remotely good service.
