The average cost for home window tinting is around $600, with most homeowners paying between $150 and $1,600. Costs can also be calculated per square foot, typically ranging from $2 to $100, or per window at around $75 each. For example, tinting one or two windows might cost between $200 and $350, while a larger project of 13 to 15 windows could range from $4,124 to $4,747.

Several factors influence the total project cost, with the number and size of the windows being the most significant. Other key factors include the type, shade, and quality of the tint film, as well as labor costs. Additional treatments, such as low-emissivity (low-E) coatings, can also increase material costs.

Window tinting offers several benefits, such as making your home more energy-efficient by blocking harsh sunlight, protecting furniture from fading, and increasing privacy. For this reason, many homeowners choose to tint only the windows in specific areas where direct sunlight and privacy are primary concerns.

ENERGY STAR®-certified windows are the most energy-efficient windows on the market. This certification means that the window meets strict efficiency guidelines set forth by the Environmental Protection Agency. While they might cost more upfront, they can save you money on your energy bills in the long run. ENERGY STAR®-certified windows lower household energy bills by an average of 12% annually.

Some frosted glass sprays can handle the outdoors, but most of them aren't built for it. Sprays made for exterior use will say so clearly on the label. Anything marked “interior use only” can't hold up against rain, UV exposure, or changing temperatures without peeling, fading, or yellowing. Outdoor-rated sprays are typically more durable, but even then, proper prep and application matter. Before spraying anything outside, double-check the product instructions. If it doesn’t specifically mention exterior use, skip it. 

A common way to modernize arched windows is to install interior window treatments that allow light through the curved portion up to and let you cover the bottom portion for privacy. You can also install plantation shutters to make an arched window look more modern. From the exterior, arched windows can appear outdated if they’re coupled with ornate trim, so toning down the decor can make your window look more natural with a modern design.
