Stucco & Siding Estimate Software for Contractors (2026)

Siding and stucco projects involve more math than most homeowners realize — facade area, opening deductions, trim footage, corner pieces, and waste. Siding and stucco estimate software runs those calculations automatically so your bid is accurate before you leave the driveway.

What siding and stucco contractors need in estimates

• Facade sqft — all elevations combined, deducting window and door openings
• Material type — vinyl, fiber cement (Hardie), wood lap, T1-11, engineered wood, stucco
• Trim and accessories — corner boards, J-channel, soffit, fascia linear footage
• House wrap and moisture barrier — often required under all siding types
• Stucco coats — scratch, brown, and finish (3-coat) vs. 2-coat systems

How to estimate a siding project

1. Measure each elevation: width × height
2. Deduct openings: each standard window ≈ 15 sqft, each door ≈ 20 sqft
3. Add 10–15% waste factor for cuts
4. Measure trim linear footage: corners, rakes, fascia, soffits
5. Add house wrap if replacing all siding (typically $0.30–$0.60/sqft material)

Common siding estimating mistakes

• Not walking all four elevations — back and side elevations are often missed in quick quotes
• Forgetting permit requirement in many jurisdictions for full siding replacement
• Underestimating stucco repair discovery — removing stucco often reveals rotted framing
