Computed decision comparison
Window replacement vs repair cost
The modeled upfront totals are $9,223 for Window replacement and $2,214 for Window repair scope proxy, a difference of $7,010.
The repair side retains the existing legacy comparison factor of 0.24 against the same ten-window replacement record. It is disclosed as a model factor, not presented as a sourced repair quote.
Side-by-side upfront cost
| Measure | Window replacement | Window repair scope proxy |
|---|---|---|
| Materials | $6,118 | $1,468 |
| Labor | $2,455 | $589 |
| Permits | $200 | $48 |
| Disposal | $450 | $108 |
| Planning range | $6,917–$12,451 | $1,660–$2,988 |
| Typical upfront total | $9,223 | $2,214 |
Window replacement derivation: Ten-window replacement default. Window repair scope proxy derivation: Existing legacy repair factor: 0.24 × replacement model.

Comparison questions
Which option has the lower modeled upfront cost?
Window repair scope proxy is lower in the current static default by $7,010. This compares model records, not contractor proposals.
Are 10-year and 20-year replacement costs included?
No sourced lifespan field exists in the shared baseline store, so the site does not invent replacement cycles. Those horizon cells remain explicitly not modeled.
Do both options use the same source system?
Yes. Both are computed from the current baseline store and index snapshots. Any proxy, quantity normalization, or retained legacy factor is disclosed beside the option.
