    home owner

    Trg and employees not only showed up late multiple times to job, but also had a lack of experience in fire sprinkler industry. The owner curses alot and is not very christian although he claims to be. After all was said and done (a month late) they tried to charge me an extra five grand. I asked what for with the owner and shop secretary Lizzete and just had multiple excuses. I WOULD NOT HIRE THEM!
