Window tinting is an easy aftermarket addition that can help reduce your electric bills, decrease glare in the home, increase privacy, protect your furniture and artwork against fading, and better control temperatures throughout your house. The national average cost for residential window tinting is $550. Many window tinting companies charge per square foot, for example, $6-$8 per square foot for materials and installation. Often, companies can offer lower rates for a larger installation project. Window size also affects cost; smaller windowpanes are harder to work with than large, rectangular windows and will likely mean a higher price per square foot. Your utility company may offer you rebates for installing window tinting. Here are two examples of average project installation cost:

• 110-square-foot window tinting project: $750 for 11 windows tinted.
• $6.80 per square foot. Customer received $150 from electrical company.
• Semi-gloss tint.
• 200-square-foot window tinting project: $1,000 for 10 large-pane windows tinted.
• $5 per square foot.
• Reflective silver tint for maximum privacy.
