What is the correct procedure for setting up kitchen cabinets? The correct procedure for setting up kitchen cabinets involves careful planning, precise measuring, securing a strong ledger board, mounting the cabinets starting from a corner, leveling each unit, and finally securing them together.
Setting up new kitchen cabinets can seem like a big job. However, with good steps, you can do it yourself. This kitchen cabinet installation guide breaks down the process. We will help you with installing kitchen cabinets safely and squarely. Follow these steps to achieve a professional look.
Preparation: Getting Ready for Cabinet Installation
Before any mounting kitchen cabinetry begins, solid prep work is key. Good prep saves time and avoids mistakes later.
Tools and Materials Checklist
Gathering everything first makes the job smoother. You will need specific tools for DIY kitchen cabinet mounting.

| Safety gear (glasses, gloves) | Always protect yourself. |
Layout and Measuring the Space
Accurate layout is the first crucial step in base cabinet installation steps and for wall units.
Determining the Starting Point
Most pros start installing kitchen cabinets from a main corner. Pick the corner that is most visible or the one farthest from the sink or stove, often the corner furthest from the main entry door.
- Find the highest point: Use your level to find the highest point on the floor along the wall where the cabinets will go. Mark this spot. This high spot becomes your baseline.
- Draw the baseline: From that highest point, draw a level line across the entire length of the wall for the base cabinets. This line marks the bottom of your base cabinet boxes.
- Mark stud locations: Use your stud finder. Mark the center of every wall stud along this line. These marks are vital for securing kitchen cabinets properly.
Layout for Upper Cabinets
Hanging upper cabinets requires a similar, but higher, approach.
- Determine upper cabinet height: Standard counter height is 36 inches (including the countertop). Upper cabinets usually start 18 inches above the counter. Measure 54 inches up from the finished floor. This marks the bottom of your upper cabinets.
- Draw the upper baseline: Draw a perfectly level line at this height across all walls.
- Mark stud locations again: Mark stud centers along this upper line too.
Step 1: Installing the Ledger Board (Support Rail)
The ledger board is a temporary strip of wood that supports the weight of the upper cabinets while you are mounting kitchen cabinetry. This step is critical for hanging upper cabinets.
Creating and Attaching the Ledger
The ledger board must be perfectly level. If the ledger is off, your upper cabinets will be off.
- Cut the ledger: Cut a piece of 1×3 lumber slightly shorter than the wall length.
- Level Check: Place the ledger board onto your marked upper baseline. Use your 4-foot level on top of the board. Make small adjustments until it reads perfectly flat.
- Securing the ledger: Drill pilot holes through the ledger board and into the wall studs at every mark. Use long screws (at least 3 inches) to attach the ledger firmly. It should hold your weight if you lean on it.
Step 2: Base Cabinet Installation Steps
Base cabinet installation steps always come before upper cabinets. You build the foundation first.
Preparing the Cabinets
Remove all doors and drawers from the base cabinets. This makes the boxes lighter and easier to handle. Locate the hardware that will join the cabinets later (kitchen cabinet hardware installation).
Setting the First Base Cabinet
Start with the corner cabinet closest to your marked baseline.
- Positioning: Lift the first cabinet into place. Rest its bottom edge directly on your drawn baseline mark.
- Plumbing and Leveling: This is the most important part of leveling kitchen cabinets. Place your level on the top edge of the cabinet (front to back, and side to side).
- Shimming: If the cabinet is not level, tap wood shims underneath the cabinet base. Slide shims until the level reads perfect. Shims also fill gaps between the cabinet bottom and an uneven floor.
- Attaching to the Wall: Once level, use your drill to drive screws through the back rail of the cabinet directly into the wall studs. Use your 3-inch screws for securing kitchen cabinets. Do not screw the cabinet to the floor.
Placing Subsequent Base Cabinets
Work outward from your first cabinet.
- Cabinet-to-Cabinet Alignment: Set the next cabinet next to the first one. Use clamps or temporary screws to hold them tightly together along the sides.
- Checking Leveling: Check the top of the new cabinet for levelness both front-to-back and side-to-side. Adjust shims as needed under this cabinet.
- Joining Cabinets: Once the second cabinet is level and flush against the first, it is time for kitchen cabinet hardware installation. Use the joining screws or specialized cabinet hardware (like connecting bolts) provided by the manufacturer to join the two boxes firmly together. Drill pilot holes first.
- Repeat: Continue this process for all base cabinets. Always ensure each new cabinet is level before joining it to the previous one.
Adjusting Kitchen Cabinet Alignment for a Seamless Look
As you join cabinets, you must look at the face frames.
- If the faces are slightly offset, use clamps to pull them tightly together before drilling the final joining screws.
- If you need slight adjusting kitchen cabinet alignment side-to-side, you can sometimes loosen the wall screws slightly, nudge the cabinet into place, and then re-tighten.
Step 3: Hanging Upper Cabinets
Hanging upper cabinets requires two people for safety and ease. The ledger board you installed earlier now takes the weight.
Preparing the Upper Cabinets
Just like the base units, remove doors and drawers from the wall cabinets.
Mounting the First Upper Cabinet
Always start with a corner unit when hanging upper cabinets.
- Positioning: Lift the cabinet up. Rest its bottom edge directly on your marked 54-inch baseline. The back of the cabinet should press firmly against the wall and the ledger board.
- Level Check: Check the cabinet for levelness in all directions. Use shims between the cabinet back and the ledger board, or between the cabinet top and the ceiling, if necessary for support while working.
- Securing to the Wall: Drive your long screws through the back rail of the cabinet, through the ledger board, and deep into the wall studs. Use at least two screws per stud bay for strong securing kitchen cabinets.
Attaching Subsequent Upper Cabinets
Work outward from the first secured unit.
- Positioning: Lift the next cabinet and press its side against the first installed cabinet.
- Alignment Check: Make sure the bottoms of both cabinets are perfectly flush with each other and the baseline.
- Joining: Use wood glue along the joining edges. Then, clamp the cabinets tightly together. Drill pilot holes and insert the joining screws for kitchen cabinet hardware installation. This makes the entire upper run act as one strong unit.
- Check the Ledger: Ensure the ledger board is still supporting the weight evenly. Remove shims from the base if they are no longer needed for support, but leave them if they are needed for adjusting kitchen cabinet alignment against a bowed wall.
Step 4: Final Adjustments and Securing
Once all boxes are mounted, it is time for final checks and securing the units firmly.
Leveling Kitchen Cabinets (Final Review)
Go back over every cabinet box after all units are mounted and joined.
- Use the level across the tops of all base cabinets.
- Use the level across the tops of all upper cabinets.
- Make minor adjustments using shims placed under the base cabinets or between upper cabinets and the ledger board/wall if needed.
Finishing the Joining Process
The bond between cabinets must be solid for drawers and doors to work right.
- Tighten Face Frames: Use pipe clamps across the front openings of the cabinets. Tighten these clamps slowly to pull the face frames flush and eliminate any gaps.
- Insert Connecting Hardware: Drive the final connecting screws or cam locks provided by the manufacturer through the pilot holes you drilled between units. This locks the assembly together. This is a key part of DIY kitchen cabinet mounting—making the run rigid.
Installing Kitchen Cabinet Hardware
This phase includes hinges, drawer slides, and handles. Proper kitchen cabinet hardware installation ensures smooth daily use.
Hinge Adjustment
Modern European hinges are fully adjustable.
- Side to Side (Lateral): Adjusts how close the door sits to the next door.
- In and Out (Depth): Adjusts how far the door sits relative to the cabinet frame.
- Up and Down (Vertical): Adjusts the door height relative to the cabinet above or below it.
Use these three screws on each hinge to achieve perfect gaps around all doors. This fine-tuning is part of the crucial adjusting kitchen cabinet alignment stage.
Drawer Slides
Drawer slides must be installed level and square within the cabinet box. Use the pre-drilled holes in the cabinet sides if available. Measure carefully for each drawer height, as small errors here will cause drawers to stick.
Common Challenges in Cabinet Installation
Even with a great kitchen cabinet installation guide, challenges pop up. Knowing how to handle them makes the difference between a good job and a great one.
Dealing with Out-of-Plumb Walls
Walls are rarely perfectly straight. This affects leveling kitchen cabinets and hanging upper cabinets.
- Base Cabinets: Shims behind the cabinet box compensate for walls that bow in or out. If the wall bows in, the cabinet bottom might sit farther out than the top. Use shims to push the cabinet back flush to the wall studs along the back rail.
- Upper Cabinets: The ledger board helps keep the top line straight. If the wall is badly out of plumb, you might need to shim the ledger board itself, not just the cabinet base.
Uneven Floors
Uneven floors directly impact base cabinet installation steps.
If your floor slopes, you must rely heavily on your baseline and shims. Never just prop up the cabinet with loose wood scraps. Use proper, sturdy shims inserted securely under the base of the cabinet box. The goal is to make the cabinet appear level relative to your countertops and level lines, even if the floor underneath is sloped.
Cabinet Gaps
Gaps between cabinets happen when frames are not pulled tight enough during joining.
If you see a gap after the glue has dried:
- Loosen the connecting screws between the two units slightly.
- Apply strong clamping pressure across the faces to squeeze the gap closed.
- Re-tighten the connecting hardware. If the gap persists, a small wood filler stick can mask minor cosmetic gaps, but structural gaps need re-clamping.
Securing Kitchen Cabinets: Safety First
When securing kitchen cabinets, remember they must hold weight—dishes, food, and sometimes even people leaning on them. Proper fastening is non-negotiable.
Importance of Stud Location
Always screw into studs whenever possible. Cabinet boxes are heavy, and drywall alone cannot hold them long-term.
- Base Cabinets: Secure every 16 to 24 inches into studs along the back rail.
- Upper Cabinets: These are high-risk if they fail. Ensure screws go through the ledger board and deep into multiple studs. If a stud falls between required screw points, use heavy-duty drywall anchors rated for high weight, though stud mounting is always superior for installing kitchen cabinets.
Cabinet-to-Cabinet Strength
The strength of the cabinet run comes from the boxes being joined tightly. The process of DIY kitchen cabinet mounting relies on strong joints. Use the correct joining hardware (often heavy-duty connecting bolts or screws) and ensure wood glue is applied liberally before tightening.
Summary of the Installation Sequence
To recap the proper flow for a successful project:
- Plan & Measure: Determine layouts and mark stud locations for both upper and base units.
- Install Ledger: Secure the perfectly level support board for upper cabinets.
- Base Cabinets: Set the first base cabinet, shim, and level it. Secure it to the wall. Join subsequent base cabinets, ensuring perfect leveling kitchen cabinets at each step.
- Upper Cabinets: Start hanging upper cabinets on the ledger board, level, and secure them to the studs. Join them tightly.
- Final Adjustments: Check all levels one last time. Complete kitchen cabinet hardware installation (hinges, slides). Perform final adjusting kitchen cabinet alignment for doors and drawers.
By methodically following these base cabinet installation steps and the procedures for mounting kitchen cabinetry above, your new kitchen will look custom-built.
Frequently Asked Questions (FAQ)
Q: How high above the counter should upper cabinets be installed?
A: The standard distance between the countertop and the bottom of upper cabinets is 18 inches. This allows enough room for small appliances and comfortable movement while working. Always double-check this height against your tallest user or any specific appliance you plan to house there.
Q: Can I install cabinets directly onto concrete walls?
A: Yes, but the method changes. You cannot use standard wood screws. For concrete or masonry walls, you must use specialized concrete screws (like Tapcons) or masonry anchors after drilling pilot holes with a hammer drill. The ledger board is still recommended for hanging upper cabinets.
Q: What if I have a gap between the bottom of my base cabinet and the floor?
A: You must fill this gap with proper wood or plastic shims. Do not just use small pieces of scrap wood that can compress later. Secure the shims firmly under the base of the cabinet structure. This is essential for stable leveling kitchen cabinets.
Q: How much overlap should there be when joining two cabinets?
A: When joining two cabinets side-by-side, the face frames should be perfectly flush or overlap just slightly to allow for a clean joint when you tighten the connecting hardware. The goal is zero visible gaps along the face line for the best appearance during installing kitchen cabinets.
Q: Is it better to install wall cabinets before or after base cabinets?
A: It is almost always better to install base cabinets first. The base cabinets establish the height reference (the counter height) which dictates where the upper cabinets must start. Base cabinets also provide a solid, level working platform for installing the upper units.
