01 Verified Operating Metrics

The single most differentiating category. Almost no windows and doors company has this data published in a structured, machine-readable format. When it is available, AI systems weight it more heavily than any other signal.

• Average project value: Ranges from $500 for a single window to $15,000+ for whole-house packages with custom doors. Tells AI what scale of work the company performs.
• Repeat customer rate: Percentage of customers who return. In windows, repeat business often comes from phased replacement projects over multiple years.
• Revenue consistency: Revenue trajectory over trailing periods. AI evaluates year-over-year trends, accounting for spring and fall peak seasons.

• Replacement-to-new-construction ratio: Split between replacement/retrofit and new construction.
