What is the difference between sectional and one piece garage door?

Sectional garage doors consist of multiple panels that slide up and overhead, while one-piece doors swing out and move upwards as a single unit.

Understanding Sectional Garage Doors

Definition and Features

Sectional garage doors are comprised of several horizontal panels connected by hinges. As the door opens or closes, these panels move in tracks that are positioned vertically and then turn horizontally into the garage. Some key features of sectional garage doors include:

  • Safety: Many sectional doors have anti-pinch design features that prevent fingers from getting caught between the panels.
  • Sealing: Due to their design, they often offer a tight seal against weather elements, which makes them energy efficient.
  • Variety: These doors come in a range of materials like steel, wood, and aluminum, and various finishes and styles.
  • Windows and Insulation: Some models offer window inserts and are insulated, providing better thermal performance.

Components and Mechanism of Operation

The operation of a sectional garage door depends on several essential components:

  • Tracks: These guide the door panels vertically and horizontally. They are typically made of steel and are anchored to the wall and ceiling of the garage.
  • Rollers: These are wheels that allow the door to move smoothly within the tracks.
  • Springs: They provide the necessary force to lift the door. Torsion springs are the most common type and are positioned above the door, while extension springs are located on the sides.
  • Hinges: These connect the door panels and allow them to pivot as the door is opened or closed.
  • Cables: In the event of a spring failure, cables prevent the door from dropping suddenly.
  • Motor: Many sectional garage doors are automated and use a motor to drive the opening and closing process.

Understanding One-Piece Garage Doors

Definition and Features

One-piece garage doors, as the name implies, consist of a single solid panel. Unlike sectional doors, there are no separate panels connected by hinges. Some distinct features of one-piece garage doors include:

  • Simplicity: A straightforward design with fewer moving parts, often leading to lower maintenance requirements.
  • Space-saving: They swing up as a single unit, which might be suitable for garages with limited headspace.
  • Aesthetics: Often, they have a classic, vintage appearance which some homeowners appreciate.
  • Material Choices: These doors are available in materials like wood, fiberglass, and steel. Some even feature glass windows for added design flair.
  • Durability: With fewer joints and seams, one-piece doors can be very durable, especially when constructed from robust materials.

How One-Piece Doors Operate

The operation mechanism of one-piece garage doors is relatively simple:

  • Pivot Points: On each side of the door, there are pivot points. As the door raises, these pivot points allow the door to swing out and then up into the garage’s overhead space.
  • Springs: Positioned on the sides of the door, these provide the necessary force to assist in lifting the door.
  • Arms: These extend from the door’s sides to the rear of the garage, guiding the door as it moves.
  • Tracks: Unlike sectional doors, these tracks only guide the top portion of the door as it moves into its overhead position.
  • Motor: As with sectional doors, many one-piece doors are also automated and incorporate a motor to facilitate the opening and closing actions.

Key Differences Between Sectional and One-Piece Garage Doors

Appearance and Design

  • Sectional Garage Doors: Comprised of multiple horizontal panels, these doors have a modern look. The design allows for varying styles, textures, and even window placements. The hinged panels become a defining aspect of their appearance.
  • One-Piece Garage Doors: Sporting a single, solid panel, these doors offer a more classic or vintage look. With no visible seams between panels (since there aren’t any panels), they present a unified facade. They may also feature design elements such as glass windows or decorative insets.

Functionality and Ease of Use

  • Sectional Garage Doors: Their design, combined with a motorized mechanism, offers smooth operation. The separate panels make it easy to replace individual sections if damaged. Often equipped with safety features, these doors can prevent accidents related to pinching or sudden drops.
  • One-Piece Garage Doors: Simplicity is key here. With fewer moving parts, the mechanism is straightforward, although manual operation might require more effort compared to sectional doors. The pivot points ensure the door swings out and then up during operation.


Space Requirements and Clearance

Considering typical sizes for residential garages:

Specification Sectional Garage Doors One-Piece Garage Doors

Installation and Maintenance Considerations

Installation Complexity and Requirements

  • Sectional Garage Doors: Installing a sectional door typically requires careful alignment of tracks, calibration of springs, and potentially an automatic opener system. While it’s feasible for skilled DIY enthusiasts with the right tools to install these doors, many homeowners opt for professional installation to ensure safety and proper function. The tracks must be perfectly horizontal and parallel, and the door must be balanced. Choosing the right type of spring based on door weight is also crucial.
  • One-Piece Garage Doors: The installation of one-piece doors is generally considered less complex than sectional doors. However, ensuring that the pivot points are correctly placed is essential. Given that these doors swing out, there’s also the need to ensure enough clearance in front of the garage. Even though it’s simpler, professional installation is still often recommended to avoid any operational issues.

Maintenance Practices for Each Type

  • Sectional Garage Doors: Maintenance involves:
    • Regularly inspecting rollers, tracks, and hinges for signs of wear.
    • Lubricating moving parts with garage door-specific lubricants to ensure smooth operation.
    • Checking the torsion springs for signs of damage or wear. If these springs break, it’s advised to seek professional help for replacement.
    • Cleaning and inspecting the door panels for signs of rust or damage, especially if they are made of metal.
    • Testing the balance of the door by disconnecting the automatic opener and manually lifting it halfway. It should remain in place if balanced correctly.
  • One-Piece Garage Doors: Maintenance steps include:
    • Regularly lubricating the pivot points and any other moving parts to prevent squeaking or stiffness in operation.
    • Checking the frame and the back of the door for signs of rot or damage, especially if the door is made of wood.
    • Ensuring that the door is balanced, similar to the test for sectional doors.
    • Cleaning the door surface, especially if it features any glass elements, to maintain its appearance.
    • Periodically checking any springs or counterweights for signs of wear or fatigue.

Cost Implications

Initial Purchase Cost

  • Sectional Garage Doors: These doors, due to their design complexity and customization options, generally have a higher initial cost. Depending on the material, design, insulation, and added features (like windows or high-quality aluminum or wood finishes), the price can vary significantly. Basic models might start at a few hundred dollars, but high-end designs or those with advanced features can reach several thousand dollars.
  • One-Piece Garage Doors: Generally speaking, one-piece doors have a lower upfront cost compared to sectional doors. A standard, no-frills one-piece door might be more affordable, starting at a couple of hundred dollars. However, adding decorative elements, better materials, or custom designs can increase the price, though it’s usually still less than a top-tier sectional door.

Long-Term Maintenance and Repair Costs

  • Sectional Garage Doors: While these doors might have a steeper initial investment, their modular design can lead to potential savings in the long run. If a panel gets damaged, for example, you might only need to replace that specific section rather than the entire door. However, the more intricate mechanism means more components could wear out over time, like rollers, tracks, or springs. Regular maintenance, which might include professional inspections or replacing worn-out parts, should be budgeted for.
  • One-Piece Garage Doors: These doors generally have fewer moving parts, which might translate to less maintenance. However, if a significant part of the door gets damaged or dented, it could mean replacing the entire door, which can be more costly than replacing a section of a sectional door. While they might require fewer regular check-ups, one still needs to factor in occasional lubrication, balance checks, and potential paint or finish touch-ups.
