How to Convert Two Garage Doors Into One

When it comes to doors, functionality is essential. A broken door profoundly impacts your daily life and hinders accessibility within your home. The same is true for garage doors. Even if your single garage doors aren’t broken, they may not be serving your lifestyle well.

If you find yourself wishing you had more space or wanting to update your garage, considering converting your split garage door into a double door.

Benefits of Double Garage Doors

As you’re doing garage door research, it’s helpful to understand what “single” and “double” garage doors are. A double garage door is one large door with enough space for two cars to enter at once. Single garage doors — when used on a two-car garage — are two doors with enough space for one car each. These two single doors may also be called split garage doors or twin garage doors.

A two-car garage with one door can be beneficial for several reasons, including:

  • Additional entry space: The pillar that separates twin garage doors can restrict your garage entry space. If your vehicle is larger than average or you have inexperienced drivers in the home, this may make parking challenging. Single doors may also increase the number of nicks and dings you accumulate on your vehicles. Installing a double door eliminates the need for a pillar and creates a larger garage door opening.
  • Updated appearance: Switching to a double door can give the front of your garage an updated appearance and make it appear larger. If your garage is attached to the front of your house, a double door can tie it into the house’s overall appearance. Whether you’re looking to sell your house or not, a new double door will increase your home’s value.
  • Simple operation: Instead of juggling two separate remotes for single garage doors, double doors allow you to operate the entire system with one remote. This simplicity helps prevent your cars from getting cluttered with door remotes and streamlines the entry and exit process.

Whatever your reason for converting, switching to a double garage door can make your garage efficient and stylish. If you’re looking to increase functionality but prefer the two-door look, there are even single garage door options that look like two doors. Accommodate your conversion to your preferences for a practical and polished upgrade.

Steps to Convert Two Garage Doors Into One

Steps to Convert Two Garage Doors Into One

Converting a two-car garage is simple when you understand the steps and procedures involved. Here are some actions to take and details about what to expect as you go through the process.

1. Take Garage Measurements

Before starting a double garage door conversion project, you’ll want to take detailed measurements of your space. In preparation to shop for replacements, here are the garage dimensions you’ll want to have on hand:

  • Height: Measure the vertical distance in feet and inches from the bottom to the top of your garage door openings.
  • Width: Measure the horizontal distance in feet and inches from the furthest left edge to the furthest right edge of your garage doors, including the pillar. It may also be beneficial to measure the pillar’s width separately.
  • Sideroom: From the garage interior, measure the horizontal distance in feet and inches from the outer edges of the garage doors to the inner garage corner.
  • Headroom: Measure the vertical distance in feet and inches from the top of the garage door to the garage ceiling.
  • Backroom: Measure the horizontal distance in feet and inches from the garage door opening to the back wall of the garage.

Knowing your garage measurements will help you select a garage door type and style that works within the dimensions. Most double car garage doors are about 16 feet wide and 7 to 8 feet high. Don’t worry if your measurements fall below or above that range. Many garage door professionals offer custom sizing to fit a variety of spaces.

2. Select a Replacement Double Door

Once you’ve taken measurements, it’s time to find a double door that fits your needs. There are several questions you’ll want to ask yourself when selecting a garage door:

  • What is your budget? Garage doors come in materials such as steel, wood, fiberglass, glass and more. The amount you want to spend on your project can help narrow down the specific material and price point you’re looking for.
  • Where is the garage located? If your garage and garage door are connected and visible from the front of the house, you may want to consider the overall house design when selecting a door. If your garage is separated or less visible, you may not need to consider the house design. In addition, you may be able to save money on heating and increase security if you choose a reinforced, insulated door for your attached garage.
  • How often do you use your garage? Does your garage door see heavy use, or is it gently used? A busy garage may benefit from more durable door material.
  • What are your design goals? Do you want your garage door to tie the house’s colors and style together, or do you want it to accent the overall style? Replacing your door can be an excellent opportunity to consider these details and change up the garage door’s current look.
  • What type of door do you want? Sectional garage doors that slide up into the garage ceiling are the most popular, but you can also choose from doors that swing out, slide apart and fold back. Keep in mind your family’s needs when selecting a type for maximum functionality.

Knowing yourself and your garage door needs can make a large number of garage door options less intimidating. Talk to a professional for advice and to be sure your selection will function as desired.

3. Remove Single Doors

Remove Single Doors

In preparation for your new double doors, your single doors will need to be removed. Though you could do this on your own, it’s often safest to call a professional. Garage doors can weigh hundreds of pounds, and removing the torsion spring system is extremely dangerous if not done properly. Whether DIY or professional, practice caution when removing your single doors.

Your single doors will typically need these components removed:

  • Garage door opener: You may need a new garage door opener to operate your double door. If this is the case, a pro will disconnect and detach the current opener from the ceiling.
  • Extension springs: Extension springs run along the horizontal tracks installed on your garage ceiling. A pro will release the tension in these springs to prepare them for removal.
  • Torsion springs: Torsion springs are mounted on the header above the garage door, and they can be very dangerous to remove without proper equipment and experience.
  • Door panels: For most sectional doors, once the proper springs and hardware are removed, the last step is to take each section off the track.

Consider how and where you can dispose of the old door materials. Check with the garage door professionals you’re working with to see if they will take care of the old door materials, or if that will be up to you.

The last step before installing your new double door is removing the pillar divider between the single doors. Garage pillar removal can be tricky, especially if your garage is old and not structurally sound. Once the pillar is removed, even well-constructed garages will need some reinforcement. Have a garage door professional with experience in double door conversions complete this task to ensure your double door is installed safely.

4. Install New Double Door

With your single doors and dividing pillar removed, you’re ready to have your new double doors installed! Though it may be possible to do this yourself, we recommend you call a professional. Double doors are even heavier than single doors, and installing them without the proper expertise can pose a safety risk.

A sectional double door will typically take shape in this order:

  • First section: Even if the garage floor isn’t level, the first section needs to be centered and leveled. Pros may use thin, wedged pieces of wood called shims to keep the bottom section level while attaching the section to the sides of the garage.
  • Additional sections: After the bottom section has been leveled, professionals will build upward by stacking the additional sections on top of each other.
  • Top strut: When the sections reach the top of the garage opening, the pros will install a support strut to the topmost section and attach it.
  • Roller tracks: Roller tracks will be installed along the sides of the garage opening to allow the garage door to open and close smoothly.
  • Upper tracks: The upper tracks will be positioned at the correct height to guide the garage door upward and into its fully raised horizontal position.
  • Torsion spring: The torsion spring will be attached to the top of the door to help raise and lower the door.

Once your new door is installed, there are a few steps you can take to maximize its life. The International Door Association recommends these routines to keep your doors functioning for as long as possible:

  • Monthly exams: Examine your garage door monthly for visible wear or damage. If you notice changes, check with a professional to see if any repairs are necessary.
  • Reversal tests: Test your opener’s automatic reversal mechanism by seeing if the door reverses when you stick an object under the door as it closes. Exercise caution while completing these tests. If your door doesn’t reverse when an item is in its path, you may have a safety issue. Have a professional look at the door and make repairs.
  • Lubrication: Keep the garage door hinges, rollers and tracks lubricated. If the door makes a loud squeaking noise as it moves, it may be time to add lubrication.

5. Add Final Touches

Add Final Touches

Once your door is in place, there are a few final touches you’ll want to cover. This includes programming the garage door opener and garage door remote. If you have a professional install your new door, they may complete this task for you. If not, it is easy to complete on your own.

Here are steps to follow to sync your remote to your garage door opener:

  • Determine the pairing method: Check the instruction manual to determine the method your remote uses for programming. Newer systems utilize a rolling code and send radio frequencies to raise and lower the garage door. This means you’ll need to press corresponding buttons on both the remote and door opener at the same time to program them.
  • Find the learn button: Your new garage door remote will have a designated “learn” button. Some models include the button on the outside, and others have it underneath the remote’s cover. Check your instruction manual to figure out where this button is located on your device.
  • Grab a ladder: You’ll need to be close to the door opener mechanism to program your remote. Find a safe ladder, set it up near the opener and climb up to it with the remote in hand.
  • Program the remotes: Hold the learn button on your remote until an indicator light blinks on the opener. While the indicator light is flashing, press the button on your remote that opens and closes the garage door. Doing so should program your remote to the door opener. Test the remote to ensure it is working correctly, and repeat this process as necessary with additional remotes. Most garage door openers can handle up to five remotes.

With your remotes programmed, you can fully enjoy your new double garage door and the convenience it offers.

Estimated Cost to Convert Two Single Garage Doors Into One

The cost of replacing two garage doors with one is different for every situation. The type of double door you purchase and the time it takes to have it installed will factor into your overall cost. According to Remodeling Magazine, the cost of removing and disposing of a large garage door and tracks and installing a new, high-quality insulated garage door with a lifetime warranty was around $3,500 in 2019.

What that price doesn’t encompass is the resale value a new door adds to your home. The Remodeling 2019 Cost vs. Value Report found that homeowners who replace their garage door recouped 97.5% of the cost in resale value. In the Houston area, homeowners added resale value with a 109.1% cost recouped rate. Whatever the cost, your garage conversion project will add curb appeal to your home and provide a valuable return on your investment.
