How we ranked these agencies
The ranking blends two things: how well each agency suits glaziers and how they convert, and a fixed seeded weighting that keeps the table honest rather than shuffling for its own sake. We look hardest at the pricing model, whether leads are exclusive, and the channel mix. Every claim reflects the agency's own stated approach; we don't invent results.
