Sills longer than 10′ or 120″ will have a seam and sent in two parts
Window Sill Guidelines for Pricing
Sill pricing is per square foot (rounded to the next 1/2 square foot). To calculate square footage: length of piece x depth of piece, divided by 144 and round to the next 1/2 square foot.
- Example: 59″ x 6 = 354. Divide by 144 = 2.458, round to 2.5
- Example: 64 x 7-1/2″ = 480. Divide by 144 = 3.333, round to 3.5
Sills deeper than 10″ are a higher price per square foot.
