I cannot recommend Perfect Dark and its owner, Gerrick, more highly.
Gerrick is the consummate professional. He did what he said he would do, when he said he would, and went above and beyond. And he made it all very easy for us. On his first visit, he not only brought a range of samples but offered to install those we were considering so we could get the best sense of how they would make our home look and feel, on the same visit. He asked the right questions and truly listened to what our needs and objectives were, tailoring his suggestions accordingly.
His follow-ups were well-timed and courteous. He patiently answered our myriad questions (there's a lot to learn in the world of tint!), and finally, come the day of installation, he and his partner showed up when they said they would and stayed to the very end until the work was done to the highest satisfaction. (Sounds basic but doesn't always happen.) A bonus for us: he never make a stink, not even a mention, about parking--which is a hassle for anyone in downtown Denver.
I would wholeheartedly recommend Perfect Dark to anyone looking for commercial or residential glass tinting.
