Number of Stories

1 Story 2 Stories 3+ Stories

Number of Downspouts Needing Repair

Add Gutter Guards? (per linear foot)

No Basic Mesh ($1.50/ft) Mid-Range Screen ($3.50/ft) Premium Micro-Mesh ($7.00/ft)

Local Labor Rate ($/hour)

#### Formula

Material Cost = Linear Feet × Material Cost/ft × Replacement Factor • Replacement Factor: Minor = 30%, Moderate = 60%, Severe = 100% Labor Cost = Linear Feet × Labor Hours/ft × Story Multiplier × Labor Rate • Labor Hours/ft: Minor = 0.10, Moderate = 0.20, Severe = 0.35 • Story Multiplier: 1-story = 1.00×, 2-story = 1.25×, 3+-story = 1.55× Downspout Cost = Downspouts × ($75 + 1.0 hr × Story Multiplier × Labor Rate) Gutter Guard Cost = Linear Feet × Guard Cost/ft Subtotal = max(Material + Labor + Downspouts + Guards, $175 minimum) Total = Subtotal × 1.15 (contractor overhead & profit) Range = Total × 0.80 to Total × 1.20
