SPF LLC

We drove to Greg's shop to describe the windows that needed tinting, and he discussed the different films and how much UV filtration we should expect.  He gave us a quote based on the square footage along with some samples so we could decide on which shade we liked best.  We had a slightly lower quote elsewhere but liked SPF's product better, so called to schedule installation.  Work was done within a week.  The workman was very neat and painstaking.  Later Greg came by to inspect the work, leave warranty information and a check for a refund over what I'd paid.  He explained he'd inadvertently overcharged me. 
The film has made a wonderful difference in keeping the room cooler (exposed on three sides).
