Exterior envelope workflow
Replace House Siding
Build an elevation-based siding takeoff, coordinate insulation and coatings, and price labor and access without hiding product-specific coverage or envelope details.
Before you calculate
- Inspect walls, flashing, sheathing, electrical service, and signs of water damage.
- Test or investigate older siding, coatings, and sealants for regulated hazardous materials.
- Confirm wind, fire, water-resistive-barrier, clearance, and manufacturer installation requirements.

Connected calculator workflow
- 1
Build the siding and accessory takeoff
Measure walls and gables, subtract openings, and estimate squares, cartons or pieces, wrap, trim, flashing, sealant, and fasteners.
Checkpoint: Use installed—not nominal—coverage from the exact siding profile and approved accessory system.Open Siding Calculator → - 2
Evaluate exterior insulation quantities
Estimate board, batt, or other insulation coverage when the approved wall retrofit includes it.
Checkpoint: A qualified designer must verify drying potential, vapor control, fastening, and window/door transitions.Open Insulation Calculator → - 3
Price field-applied coatings
Estimate primer and finish coverage for paintable siding and trim surfaces.
Checkpoint: Confirm factory-finish warranty, compatible primer, surface preparation, and application conditions.Open Paint Calculator → - 4
Price access, removal, installation, and overhead
Combine material takeoffs with scaffolding or lift rental, disposal, crew burden, overhead, contingency, and margin.
Checkpoint: Separate concealed damage and hazardous-material remediation with clear allowances or change-order terms.Open Contractor Job Pricing Calculator →
