Planning Your Shed Door Build

Measuring And Sizing Your Shed Door

Figuring out a plan for your shed door is the first step. And accurate measuring is the cornerstone of building a shed door that fits perfectly.

Start by measuring the height and width of your shed's door opening. From our experience, it's wise to subtract about half an inch from both the height and width to provide enough clearance for the door to swing freely without sticking. This gap will also accommodate any potential expansion due to humidity.

For double doors or building barn doors for a shed, remember to include the space for the door jamb in the center. It's also important to consider the door's thickness and the depth of any siding or trim you plan to add, ensuring these elements don't impede the door's operation.

After taking these measurements, review them once more to confirm their accuracy before moving on to cutting your materials.

Choosing The Right Materials

Wood Types And Their Benefits

Selecting the right type of wood is essential for the durability and appearance of your shed doors. Here's a straightforward list of options and their advantages:

  • Cedar: Naturally resistant to rot, decay, and insect attacks, cedar is a top choice for outdoor use. Its durability in various weather conditions makes it a long-lasting option.
  • Pine: A budget-friendly option, pine is easy to work with due to its softness. It's best used in dry climates or with a good protective finish to prevent rot.
  • Redwood: Similar to cedar, redwood offers excellent resistance to moisture and decay, and it's also less prone to warping.
  • Oak: Known for its strength, oak is a hardy choice that can withstand heavy use. It's also resistant to fungal and insect problems.
  • Plywood: For those looking for an economical choice, treated plywood can serve well for shed doors, especially when painted or sealed properly.
  • Composite: Though not solid wood, composite materials offer a maintenance-free alternative that resists rotting and splitting.

Each wood type has its own set of benefits, so consider your specific needs, such as climate, budget, and aesthetic preference, when making your choice.

Tools And Hardware

Choosing durable hardware is crucial for constructing shed doors that will endure the elements and frequent use. Here's a list of the tools and hardware you'll need:


  • Tape measure: For precise measurements
  • Circular saw or table saw: To cut wood to the correct dimensions
  • Power drill and bits: For pre-drilling screw holes and driving screws
  • Carpenter's square: To ensure your cuts are perfectly square
  • Level: To make sure your doors hang straight
  • Hammer or nail gun: For attaching parts when screws aren't suitable
  • Sandpaper or a sander: To smooth out any rough edges
  • Paintbrush or roller: For applying protective finishes


  • Hinges: Choose heavy-duty, galvanized, or stainless steel hinges to support the door's weight
  • Screws: Exterior-grade screws to resist rust and corrosion
  • Latch: A sturdy latch will keep your doors closed securely
  • Handle: For easy opening and closing
  • Weatherstripping: To seal gaps and keep out drafts
  • Lockset (optional): For added shed door security if needed

Step-by-Step Guide to Building Shed Doors

Removing Old Shed Doors

For replacing shed doors without damaging the existing frame, follow these steps:

  1. Examine how the doors are attached to the shed. Look for screws, nails, or bolts that may be holding the door in place.
  2. If the door is large, have someone help you hold it as you remove the hardware, or prop it up to prevent it from falling.
  3. Start by unscrewing or prying out any screws or nails from the hinges. If bolts are used, you may need a wrench or socket set to remove them.
  4. Once all hardware is removed, carefully take the door off the frame. If it's stuck, gently tap it with a hammer or mallet to loosen it.
  5. After the door is out, remove any remaining hardware from the frame. Clean off old paint, rust, or debris to prepare for the new door installation.
  6. Before proceeding, ensure the door frame is not damaged and is still square. Repair any issues to ensure a good fit for the new doors.

Preparing The Doorframe

To prepare the door frame for your new shed doors, start by checking for any signs of damage or rot. Replace any compromised wood to prevent future structural issues. Next, use a level to verify that the top and sides of the frame are level and plumb.

If adjustments are needed, shim the frame until it's properly aligned. It's also essential to ensure that the frame is square; measure diagonally from corner to corner, and both measurements should be equal. If they're not, adjust the frame accordingly.

Sand down any rough spots and apply a wood preservative or primer to protect the frame, especially if you're working with a wooden frame.

Cutting And Assembling The Frame

When it comes to cutting the frame for your shed door, precision is absolutely critical. Start by referring to the detailed measurements provided in our kits, but don't rely on them blindly. Always cross-reference these with the actual dimensions of your shed's door opening to account for any variances.

Measure the height and width of the opening at multiple points to ensure accuracy, as some sheds may have settled or shifted over time, leading to slight discrepancies in measurements.

For the cutting process, a sharp blade is non-negotiable. Dull blades can lead to jagged cuts and potential inaccuracies. A miter saw is ideal for making straight, clean cuts, but if you're using a circular saw, a guide can help maintain straight lines.

Always support the wood securely on a stable surface to prevent movement as you cut. And, without question, prioritize safety: wear eye protection, ear protection, and a dust mask to shield yourself from sawdust and debris.

Before making any cuts, double-check your measurements and mark your cut lines clearly with a pencil or chalk line for visibility.

Attaching The Siding

When it comes to attaching the siding to your shed door, the method will vary slightly depending on the type of siding you've chosen.

For traditional lap siding, begin by ensuring that each board is level before securing it. Start from the bottom and work your way up, overlapping each piece to shed water effectively. Nail or screw the siding into place, positioning fasteners near the top of each board where the next board will overlap, which helps to conceal the fasteners and provides a clean look.

For a plywood approach, the process is more straightforward but no less critical in terms of precision and care. Measure and cut your plywood to fit the door frame, leaving a small gap around the edges for expansion.

Apply construction adhesive to the frame to help secure the plywood, then fasten it with screws spaced every 6 to 8 inches along the perimeter and across the center support of the frame. This ensures the siding will stay flat and firm against the frame.

In both cases, it's best practice to install a breathable barrier, such as house wrap, between the frame and the siding. This barrier helps to prevent moisture from getting trapped, which can lead to wood rot and a decrease in the longevity of your shed door.

It's also important to know how to seal shed doors properly. Use a quality exterior-grade sealant along the bottom and any seams to further protect against moisture ingress. With the siding securely attached and properly sealed, your shed door will not only look great but also stand up to the rigors of outdoor exposure.

Assembling And Mounting the Door

Place The Screws

Assembling your shed door starts with the frame. Lay out the cut pieces on a flat surface, aligning them according to your door design.

When joining the corners, use screws that are long enough to provide a secure hold but not so long that they protrude through the wood. Corner brackets or angle braces can be added for extra stability. Screws should be placed at even intervals, usually every 6 to 8 inches along the joints, to maintain structural integrity.

Install The Hinges

Shed door hinge placement is critical for a well-functioning door. Typically, for a standard-sized shed door, you'll want at least three hinges: one near the top, one near the bottom, and one in the middle.

For heavier doors, consider adding additional hinges to distribute the weight more evenly. Use a drill to create pilot holes for the screws, which prevents the wood from splitting. Attach the hinges to the door frame first, then to the shed, ensuring they are level and aligned.

Mount The Door

With the hinges attached to the door, it's time to install the shed door. If possible, have someone help you hold the door in place while you screw the hinges into the shed frame.

Check that there's an even gap around the door to prevent sticking and allow for easy opening and closing. Use shims to adjust the door position if necessary.

Final Checks

Before considering the job done, step back and inspect the door from a distance to ensure it's hanging straight and true. After installing our fair share of doors, we've found it best to open and close the door several times to confirm that it swings effortlessly and latches securely.

Make any final adjustments to the hardware if necessary, and give all moving parts one last check for proper function.


Building shed doors might seem daunting, but with the right tools, materials, and a bit of Homestead Supplier know-how, you'll be well on your way to creating doors that are not just functional but also add character to your outdoor space.
