Reading the scorecard

Rating is the live Google star average. Review volume is how many customers have rated the business, compared with the others on this page. Confidence weighs the rating by that volume, so a 4.9 from more than two hundred people counts for more than a similar score from fewer than fifty. Recency reflects how lately customers have been leaving reviews.

What drives an insulation quote in Baton Rouge

Insulation quotes tend to move with the square footage, the method (blown-in versus open-cell or closed-cell spray foam), how much old material has to come out, and whether air sealing is included.
