How to Replace Garage Door Glass: A Beginner’s Guide

Step 1 – Check Your Garage Door Manufacturer’s Guide

Your garage door manufacturer’s guide may contain the necessary information and guidelines for purchasing and replacing the door glass. Check if your garage door is a panel door or a one-piece door.

A panel door consists of different sections connected by hinges, and each section can have a glass insert that can be replaced individually. A one-piece door can only be replaced as a whole.

Step 2 – Remove the Broken Glass

Firstly, put on your safety goggles and gloves. You don’t want to get hurt while handling broken glass. Use a putty knife or a screwdriver to remove the glazing compound (or caulk) that holds the glass in place. Carefully remove the broken pieces of glass and dispose of them properly.

Put on Your Safety Goggles and Gloves

Ensure that the area around the garage door is clean and free from glass debris.

Step 3 – Choose the Replacement Glass

The replacement glass should be similar in size and thickness to the original piece. The glass must be tempered, which means it should be adequately durable and robust to withstand objects crashing into it. You need to measure the dimensions of the glass frame accurately.

For the correct thickness, you will also need to read the manufacturer’s guide. You can get the replacement glass at your local hardware store or order from suppliers online.

Step 4 – Install the New Glass

Start by applying a thick layer of glazing compound to the frame. You want to create a clean, watertight seal around the glass. Carefully place the new glass into the frame. Push it into place and gently press the glass to evenly distribute the glazing compound.

Apply another layer of compound to the top of the glass, pressing it firmly into place and smoothing it over with your putty knife. Let the glazing compound cure for at least three days before painting.

Step 5 – Paint the Glazing Compound

After three days, it’s now time to paint over the glazing compound. You can choose to match the color of your garage door or use a different color for contrast. Be sure to use exterior paint that is compatible with the material of your garage door. Apply at least two coats of paint and let it dry before using the garage door.

Step 6 – Reinstall the Door Panel

If you have a panel door, carefully reinstall the door panel back onto the hinges. Make sure all the sections are properly aligned and secured. Use lubricant on any moving parts to ensure smooth operation of your garage door.

5 Considerations Things When You Need to Replace Garage Door Glass

1. Type of Glass

When replacing garage door glass, one of the most important things to consider is the type of glass you need. Several types of glass are available for garage doors, including tempered glass, laminated glass, and polycarbonate. Each type of glass has its own advantages and disadvantages, so it’s important to choose the right one for your needs.

2. Size and Shape

You will also need to consider the size and shape of the replacement garage door glass. The size and shape should match the existing window to ensure a proper fit. If you are unsure about what size or shape you need, measure the existing window and bring those measurements with you when shopping for a replacement.

3. Energy Efficiency

Another important factor to consider when replacing garage door glass is energy efficiency. Look for windows with a low U-value rating, which indicates that they are better at insulating than windows with higher U-values. This will help keep your home cooler during the hot summer months and warmer during the cold winter months.

4. Cost

Cost is also an important factor to consider when replacing garage door glass. Make sure to shop around to get the best price on your new window before making a purchase decision.

Also, be sure to factor in any installation costs that may be associated with your purchase as well as any warranties or guarantees offered by the manufacturer or retailer.

5. Maintenance

Finally, make sure to consider how much maintenance will be required for your new window once it has been installed in your garage door frame. Many types of windows require regular cleaning and maintenance to keep them looking their best over time, so make sure you understand what type of care will be needed before making a purchase decision.

5 Benefits of Replace Garage Door Glass

1. Improved Aesthetics

Replacing the glass in your garage door can give it a fresh, modern look. Glass panels can be customized to match your home’s style and come in various colors, textures, and patterns.

This allows you to choose a design that will complement your home’s exterior and make it stand out. Replacing the glass in your garage door will make it look brighter and more inviting.

2. Increased Natural Light

Garage doors with glass panels allow more natural light to enter your garage, making it easier to see what you’re doing when you’re working on projects or cleaning up after a long day. The extra light also makes it easier to find items stored in your garage without turning on the lights every time you go in there.

3. Enhanced Security

Replacing the glass in your garage door with tempered or laminated glass can enhance your home’s security. Tempered glass is much stronger than regular glass and is designed to break into small pieces if shattered, making it difficult for intruders to access your home through the garage door. Laminated glass is even stronger than tempered glass and provides extra protection against potential intruders.

4. Improved Insulation

Replacing the glass in your garage door with insulated panels can help improve energy efficiency by keeping heat inside during winter and reflecting heat away during summer. This can help reduce energy costs and make your home more comfortable year-round.

5. Reduced Noise Pollution

Insulated garage doors also greatly reduce noise pollution from outside sources such as traffic noise or loud neighbors. The insulation helps absorb sound waves so that they don’t enter your home, allowing you to enjoy peace inside while still being able to hear what’s going on outside when needed.

6 Common Mistakes People Make When Trying to Replace Garage Door Glass

1. Not Measuring the Existing Glass Properly

One of the most common mistakes people make when replacing garage door glass is not measuring the existing glass properly. Taking accurate measurements is essential to ensure the new glass fits correctly and requires no additional modifications.

To do this, you should measure both the height and width of the existing glass from the inside edge of the frame.

2. Not Choosing the Right Type of Glass

Another mistake people often make when replacing garage door glass is not choosing the right type for their needs. Different types of glass are designed for different applications, so it’s important to select a type that will meet your requirements.

For example, if you need a more secure option, you should choose tempered or laminated safety glasses, as these offer superior protection against break-ins.

3. Not Installing It Correctly

Installing garage door glass incorrectly can be dangerous and can also cause damage to your home or vehicle if done improperly. This is why it’s important to hire a professional to install your new garage door glass for you, as they will have experience in doing so safely and correctly.

Additionally, some garage door glass types require special installation tools or techniques, which can only be provided by a professional installer.

4. Not Considering Insulation

When replacing garage door glass, many people forget to consider insulation options as well. If your garage gets very hot or cold during certain times of the year, adding insulation can help keep temperatures more comfortable while also reducing energy bills in the long run.

Several types of insulation are available for garage doors, such as foam board insulation or reflective bubble wrap insulation.

5. Not Considering Security Options

Security should also be considered when replacing garage door glass, as this can help protect your home from intruders or other threats. Several security features available for modern garage doors can provide an extra layer of protection against break-ins or vandalism, such as reinforced frames and shatterproof windows.

You may also want to consider adding motion-sensing lights around your property for added security at nighttime hours.

6. Failing to Clean Up After Installation

Finally, many people forget to clean up after installing their new garage door glass, which can lead to problems if not addressed properly. After installation is complete, it’s important to check for any leftover pieces of debris or dust that may have been left behind during installation and remove them before closing up your garage again.
