How To Tint House Windows: DIY or Professional?

Contrary to popular belief, window tinting isn’t just for cars. In recent years, many homeowners are opting to tint their windows to save on energy costs and gain more privacy. However, with DIY and professional options available, knowing which one to pick can be challenging. 

Read on to learn everything you need to know about home window tinting, from the pros and cons to installation tips.

What Are the Benefits of Home Window Tinting?

While window tinting for cars is largely an aesthetic choice, tinting home windows is a bit different. Tinted windows offer several advantages for homeowners looking to improve their living spaces, including the benefits below.

Lower Energy Costs

One of the biggest advantages of window tinting is that it reduces energy costs. Tinted windows can block up to half the sun’s heat in summer, saving homeowners up to 30% on their utility bills. This makes window tinting an affordable alternative to replacing existing windows with low emissivity (low-E) or triple-pane models.

In some areas, such as California and Arizona, utility companies even offer rebates to customers who install home window tinting, further increasing the potential savings.

Enhanced Home Security and Safety

Home window tinting can prevent burglars from seeing valuables through the windows, allowing homeowners to keep their curtains open and enjoy natural light without compromising safety.

Some window films even add an extra layer of protection by preventing broken glass from shattering. This deters burglars and keeps residents safer in case of accidents or storm damage.

Protection for Interior Furnishings

Window tinting blocks up to 99% of the sun’s UV rays, which can cause fading and early deterioration of carpets, walls, and furniture. This is especially beneficial for homes with dark furniture, which tends to fade more quickly. While sun fading may be a minor problem for most homeowners, it can be a big issue in hot, sunny climates.

Reduced Glare and Improved Comfort

Tinted windows reduce the amount of light entering a home, preventing pesky glares when watching TV or on the computer.

What Are Potential Drawbacks of Window Tinting?

While window tinting offers many benefits, it also comes with some drawbacks. Consider the following downsides before making a decision:

Limited Benefits in Cooler Climates

In cooler regions, solar film can block too much winter sunlight and warmth, potentially leading to increased heating costs. This extra energy use might offset any summer savings, making window tinting less beneficial in these areas.

Nighttime Privacy

While window tinting provides daytime privacy, it doesn’t offer much protection after dark. With interior lights on and curtains open, passersby can still see into a home at night, even with tinted windows.

Installation Challenges

Applying window film can be tricky, especially on windows with multiple small panes or thick frames with protruding latches. These types of windows are more prone to creasing or bubbling during installation.

Plant Life Concerns

Since window tinting keeps harmful sunlight from coming through windows, there’s a chance it may affect your indoor plants. However, window tinting doesn’t usually block the spectrum of light that plants need to grow, only the harmful UV rays. Still, if you have plants that are struggling to stay alive, certain films may make it more difficult for them to get enough sun.

Risk of Thermal Breakage

Window film can increase the thermal stress on glass. If you install it incorrectly or apply it to a window with cracks or flaws, the glass might break. Because of this, thoroughly inspect older windows before applying film.

Window Warranty Concerns

Applying window film can sometimes void a window’s warranty, depending on the manufacturer. However, some tinting manufacturers offer to match the window manufacturer’s warranty, ensuring continued coverage. Talk to your manufacturer about the warranty before buying or installing.

Types of Window Tinting Films

There are four types of window tinting films, each with different benefits:

• Basic tinting film: Reduces sunlight and glare.
• Solar or low-E film: Controls both light and heat.
• Spectrally selective film: Blocks UV rays while allowing visible light to enter.
• Security film: Designed to resist impact and tearing.

How to Choose the Right Window Tint for Your Needs

Window films serve multiple purposes and don’t all work the same way. Here are some factors to consider:

Energy Efficiency Ratings

Look for films with the NFRC (National Fenestration Rating Council) label. This independent organization tests and certifies window products for energy efficiency.

Reflective vs. Non-Reflective Films

Reflective window films have a mirrored surface, giving them a flashy, non-traditional look. Non-reflective films are designed to absorb and reduce heat without the mirror effect, making them look more natural. Another option is frosted window film, which isn’t transparent like traditional tinting and isn’t reflective. It provides privacy while letting in plenty of natural light.

Pros and Cons of DIY Vs. Professional Installation

Each method of installation has its own benefits and drawbacks. DIY installation is cost-effective and can be done on your own time. However, it can be time-consuming, and there’s a risk of error. Poor installation can shorten the tint’s lifespan.

Professional installation usually includes a warranty and is a better option for homeowners who are unsure of their DIY abilities or lack the time. However, it comes at a higher cost than DIY.

DIY Window Tint Installation Steps

While DIY window tint installation can save money, there’s a bit of a learning curve. Here’s an overview of the DIY installation process:

1. Measure the window and cut the film to fit each window pane, leaving an inch of extra film on all sides.
2. Clean the window thoroughly using a mixture of soap and water.
3. Wet the window before applying.
4. Apply the film from the top down, with the liner facing outward.
5. Remove the liner while spraying it with water to prevent static.
6. Use a squeegee to remove water and air bubbles, working from the center outward.
7. Trim the film to fit, leaving a 1/16-inch gap between the film and the window frame.

Cost Considerations for Window Tint Installation

The cost of installing window tinting varies depending on the type of film, the size of the windows, and whether you opt for DIY or professional installation.

DIY Costs

According to Angi, basic window tinting film rolls start at around $2 per square foot. Choosing a higher-end film, such as low-E or decorative options, will increase the cost. You may also need to purchase tools such as squeegees, cutting instruments, and application solutions if they don’t come with your window tinting kit.

Professional Installation Costs

According to Angi, professional window tinting costs $604 on average but can range from $316 to $932, depending on the complexity of the job and the quality of the film. While this option is more expensive, it offers a higher-quality finish and usually comes with a warranty.

Tinted Window Maintenance and Care Tips

To keep your tinted windows looking their best, keep these maintenance tips in mind:

• Wait at least 30 days after installation before cleaning the tinted windows.
• Clean the windows with a soft cloth or sponge and mild soap.
• Avoid abrasive cleaners or materials that could scratch the film.
• Check the tint periodically for signs of wear or damage, such as bubbling or peeling.

Final Thoughts About Home Window Tinting

Home window tinting can be a valuable investment for homeowners looking to improve energy efficiency and enhance privacy. The initial investment can cost upwards of $600, but depending on how much heat they repel, they could pay for themselves in energy savings within months. Weigh the costs, benefits, and drawbacks before committing.
