What’s on a siding estimate
Every line is one part of the siding job, priced on its own so the client can see what each part of the job costs.
| Line item | Unit | Why it’s its own line |
|---|---|---|
| Existing siding tear-off and debris removal | per sq ft | Tear-off is priced by area and includes hauling the old siding away. |
| OSB wall sheathing repair and replacement | per sq ft | Damaged sheathing only shows after tear-off. Price it per square foot as an allowance. |
| House wrap weather barrier installation | per sq ft | The weather barrier behind the siding keeps water out, and it’s priced by area. |
| Window and door opening flashing tape | per linear ft | Openings are where walls leak. Flashing them is linear work clients should see. |
| Vinyl siding starter strip installation | per linear ft | Starter runs along the bottom of every wall, priced by the foot. |
| Vinyl outside corner post installation | per linear ft | Corners are counted in linear feet and vary with the shape of the house. |
| Vinyl J-channel installation at openings | per linear ft | J-channel trims every window and door, so the number of openings shows in the price. |
| Vinyl siding panel installation | per sq ft | Panels are priced per square foot of wall. |
| Fiber cement lap siding installation | per sq ft | Fiber cement is heavier and slower to cut and fasten than vinyl, so it’s priced separately. |
| Vinyl soffit panel installation | per sq ft | Soffit is priced by area under the eaves, separately from the walls. |
| Aluminum fascia cover installation | per linear ft | Fascia covers run along the roof edge and are priced by the foot. |

How siding jobs are priced
Siding is priced by the square foot of wall, or by the square of 100 square feet, the same as roofing. Measure each wall, subtract large openings such as garage doors, and add waste for cuts around windows and gables. The material sets most of the price: vinyl goes up fastest, fiber cement is heavier and slower to cut and fasten, and wood shingles are slower still.
Everything that isn’t a panel is linear: starter strip, outside and inside corners, J-channel around openings, fascia and trim boards. On a house with many windows and corners, that trim adds up to a large share of the job, which is why it gets its own lines instead of hiding in the per-square-foot price.
Tear-off shows you the wall underneath. Price sheathing repair as an allowance per square foot, and list the house wrap and the flashing at openings so the client sees the weather barrier, not just the finish.
