Size readings, priced apart by frame
| Size row | Frame A reading | Frame B reading |
|---|---|---|
| 6x6 row | $50-$250 | inside the $200-$850 line |
| 8x10 row | $75-$300 | inside the $200-$850 line |
| 8x17 row | $100-$400 | inside the $200-$850 line |
| 13x13 row | $100-$400 | inside the $200-$850 line |
| 14x37 row | $200-$450 | inside the $200-$850 line |
| 17x29 row | $300-$500 | inside the $200-$850 line |
Each reading is one frame counting of one size row, never blended. Frame B prints no size table, and that absence stands. The same material is never carried across the size line.
Flue count rows, priced apart by frame
| Flue count row | Frame A reading | Frame B reading |
|---|---|---|
| Single-flue row | inside the $190-$650 band, at its lower end | inside the $200-$850 line |
| Multi-flue row | inside the $190-$650 band toward the $1,000 high end | inside the $200-$850 line |
| Outside-mount row | counted with the multi-flue rows at the top of the band | inside the $200-$850 line |
Frame A names single-flue caps as its lowest-counted row and multi-flue and outside-mount caps as its highest, inside one band. Frame B prints one cap line for every flue count.
Material lines behind the size rows, printed once
| Material row | Frame A reading | Frame B reading |
|---|---|---|
| Galvanized steel row | low end at $75 for a basic galvanized steel cap | inside the $200-$850 line |
| Stainless steel row | inside the $190-$650 band, average about $300 | inside the $200-$850 line |
| Copper row | high end at $1,000 for custom copper | inside the $200-$850 line |
| Custom-fabricated row | inside the $190-$650 band toward the $1,000 high end | inside the $200-$850 line |
The material lines stand once here, shared by the size rows, each band as printed.
The crown, the flashing, and the Los Angeles read
| Own-field line, as printed | 2026 reading |
|---|---|
| Frame B crown repair row | $200-$700+ |
| Frame B crown replacement row | $1,000-$3,000 |
| Frame B flashing row | $300-$1,800 |
| Frame A Los Angeles read, apart | $216-$738, average $341, inside Frame A only |
The crown and flashing rows stand as their own Frame B tickets, never cap rows. The frames count the same cap job on different bases -- a replacement band with a size-and-material table in Frame A ($190-$650, average about $300) against a repair-table line inside a wider repair menu in Frame B ($200-$850 for the unit and the job together). The Los Angeles read in Frame A at $216-$738, average $341, stands inside Frame A alone, apart from its national band, never carried into Frame B. Those differences are named as frame differences on every page, never averaged.
The neighbours named apart
Named apart, never a row here: the chimney sweep visit (diagnosis and cleaning, its own field), chimney liner installation, chimney repair and masonry work, chimney crown repair and replacement, and flashing work -- this cluster carries no sweep, liner, repair, crown, or flashing guide of its own, and the chimney crown and the flashing stand as their own fields on every page.
