What the scorecard measures

Rating is the live Google star average. Review volume is how many customers have rated the business. Confidence weighs the rating by that volume, so a 4.8 from hundreds of people counts for more than a 5.0 from a handful. Recency reflects how recently customers are still leaving reviews.

What drives the cost of siding in St. Louis (2026)

No prices are published here. Siding quotes move with the size of the house, the material (Westside’s site names Hardie, LP SmartSide and vinyl), how much trim, fascia and gutter work comes with it, and whether the roof is being replaced at the same time. Ask each company for an itemized written quote so the numbers can be compared line by line.
