I have had vehicles done at Tintmasters Motorsports in Burnsville and they did a superb job. I know they also do commercial and residential windows, but do not have experience with them in that regard. I believe they also have a Maplewood location, worth giving them a call.
I have found that the professional shops that will only tint vehicles to legal limits or with prescription only, are the reliable and quality shops you want. If the shop doesn’t care about following the law, why would they care about quality? Just my opinion. Obviously there is no law on tinting home windows, but almost all shops that do homes, also do vehicles.
