Window Glass Replacement Cost Estimator

Estimate the total cost to replace window glass based on dimensions, glass type, thickness, and labor rates.

Window Width (inches)

Window Height (inches)

Number of Panes

Glass Type

Single Pane (standard annealed) Double Pane (insulated IGU) Triple Pane (high-efficiency IGU) Tempered / Safety Glass Laminated / Impact Glass Low-E Coated Glass

Glass Thickness

3/32" (2.4 mm) – thin single pane 1/8" (3 mm) – standard single pane 3/16" (5 mm) – standard double pane 1/4" (6 mm) – heavy / tempered 3/8" (10 mm) – thick laminated

Labor Rate ($/hour)

Estimated Labor Hours per Pane

Include Disposal / Haul-Away Fee?

No Yes (+$25 per pane)

Contractor Markup (%)

#### Formula

Area (sq ft) = (Width × Height) ÷ 144 Billable Area = max(Area, 2.0 sq ft)  [minimum charge] Material Cost / Pane = Billable Area × Glass Price ($/sq ft) Labor Cost / Pane = Labor Rate ($/hr) × Labor Hours Disposal Cost / Pane = $25 (if selected) Subtotal / Pane = Material + Labor + Disposal Subtotal (all panes) = Subtotal / Pane × Number of Panes Markup Amount = Subtotal × (Markup % ÷ 100) Grand Total = Subtotal + Markup Amount Cost Range = Grand Total × 0.85 to Grand Total × 1.15
